After the completion, data processing equipment could carry out subsequent processings to generated all data, so ensure that data from generate to
The real-time of the process of processing.
In this step, the data in message queue are parsed, a plurality of data after being parsed, wherein parsing
Every data afterwards is all corresponding with the generation time stamp of the data.Wherein, the generation time stamp of any one data refers to this
At the time of data generate；For example, 10,000 datas that ad log server was generated at 14: 23 30:, at this point, this 10,000
Data generation time stamp be exactly 14 points 23 seconds 30 minutes.
In the present embodiment, the process data in message queue parsed, can using distributed mode into

It should be noted that a plurality of parsing data are obtained after S201 parses the data in message queue, for
Data after the parsing that S201 is obtained, S202 and the two steps of S203 can execute parallel.
S203, the value that pre-set level is calculated according to the data after parsing, and save and calculate according to the sequencing of calculating
The value of obtained pre-set level.
In this step, pre-set level can be determined according to the actual situation by technical staff, and the present embodiment is not to pre-
If index limits.The value of pre-set level is calculated to which content in the data after parsing, and how to calculate default finger
The process of target value is the prior art, and which is not described herein again.
In the present embodiment, since a generation time stamp corresponds to many datas, to a generation time stamp pair
The data answered calculate the process of the value of pre-set level, it may be necessary to which the multiple calculating of progress can just obtain generation time stamp and correspond to
Pre-set level final value.In this step, it according to the sequencing of calculating, saves generation time and stabs corresponding default finger
It is marked on each calculated result, i.e., from the angle of time, the number of the calculated result saved is successively increased.Wherein, often
Secondary calculated result includes: the generation time stamp of data, this pre-set level (for example, exposure rate) calculated, this calculates
Value (for example, exposure rate value) of the pre-set level arrived etc..
In the present embodiment, the process that corresponding data calculate the value of pre-set level is stabbed for any one generation time
In, each parameter corresponds to a set of logic of propositions for being calculated data.It wherein, will be to any one generation time
The process that corresponding data calculate the value of pre-set level is stabbed, multiple calculating tasks are generated, in the process for executing calculating task
It is possible that failure, so that generated calculating task is actually but not carried out, for convenience, the present embodiment will have been generated
But the calculating task being not carried out is known as the calculating task accumulated.
It should be noted that above-mentioned S201~S203 is the process that the data in message queue are carried out with analytical Calculation, under
S301~the S303 in face is the detection process to calculating task state, and in the present embodiment, the process of analytical Calculation and calculating are appointed
The process of the detection of business state is to execute parallel.
Specifically, Fig. 3 is a kind of method of the detection calculating task disclosed in the present application with the presence or absence of accumulation, including following step
It is rapid:
S301, every preset duration, detect whether in the presence of accumulation calculating task, if it is present execute S302, it is no
Then, S301 is executed.
In the present embodiment, it is carried out in calculating process to the data after parsing, can have an interface, if there is heap
Long-pending calculating task can show the quantity for the calculating task currently accumulated in the interface.For the heap being shown in interface
Long-pending calculating task is that how to determine is the prior art, and which is not described herein again.
In this step, it detects whether the calculating task in the presence of accumulation, can be accumulated by crawler technology from display is current
Calculating task interface in crawl the calculating task currently accumulated, if crawling the quantity for the calculating task currently accumulated
It is not zero, then it represents that there is currently the calculating tasks of accumulation；Otherwise, if the quantity for crawling the calculating task currently accumulated is
Zero, then it represents that there is currently no the calculating tasks of accumulation.
A length of delay duration when needed for S302, the determining calculating task for completing accumulation.
In this step, a default calculating duration is corresponding with for each calculating task, therefore, by the calculating of accumulation
The total quantity of task and the default product for calculating duration, duration needed for exactly completing the calculating task of accumulation, for the side of description
Just, it is known as the calculated duration of institute to postpone duration.
S303, calculating task state and data delay are saved, and returns and executes S301.
In the present embodiment, calculating task state includes stacking states and normal condition, and the calculating if there is accumulation is appointed
Business, then calculating task state is stacking states, and if there is no the calculating task of accumulation, then calculating task state is normal shape
State.A calculating task state is detected every preset duration, in this step, when the calculating task state that will test is with delay
Length is saved.
Above-mentioned S201~S203 and S301~S303 is to carry out generation time in the application and stabbing corresponding default finger
Whether target value accurately does basis, i.e., whether the value that any one generation time stabs corresponding pre-set level is accurately examined
It surveys, needs to be detected based on the obtained result of S201~S203 and S301~S303.
It should be noted that above-mentioned S201~S203 calculate generation time stab corresponding pre-set level value process,
Whether the value that above-mentioned S301~S303 stabs corresponding pre-set level to the detection process and generation time of calculating task is accurate
Detection process these three processes execute parallel.
Stabbing the value of corresponding pre-set level for generation time, whether accurate detection process is introduced following.
Due to stabbing the process that corresponding data are parsed and calculated to each generation time that data producer generates, be by
It is successively carried out according to the sequencing of generation time stamp, therefore, the newest value that each generation time stabs corresponding pre-set level is quasi-
The true time is also to have sequencing, i.e., the newest value that forward generation time stabs corresponding pre-set level is also first to reach
To accurate.
For example, data producer generate data generation time stamp be followed successively by 14 points 30 seconds 23 minutes, 14 points 31 seconds 23 minutes
With 14 points 32 seconds 23 minutes, it is also 14 points of 23 minutes 30 seconds, 14 that the newest value of corresponding pre-set level, which reaches accurate sequencing,
Point 31 seconds 23 minutes and 14 points 32 seconds 23 minutes.
I.e. when the newest value of 14 points of 30 seconds 23 minutes corresponding pre-set levels does not reach accurate, 14 points 23 minutes 31
The newest value of second and 14 points of 32 seconds 23 minutes corresponding pre-set levels will not reach accurately, therefore, if 14 points of detection
While whether the newest value of 23 points of 30 seconds corresponding pre-set levels accurate, detection 14 points 31 seconds 23 minutes and 14 points 32 seconds 23 minutes
Whether the newest value of corresponding pre-set level is accurate, reduces detection efficiency.
Therefore, in the present embodiment, in order to improve detection efficiency, pass through each generation time in detection sliding time window
The whether accurate mode of value of corresponding pre-set level is stabbed, each generation time stamp that successively detection data producer is sequentially generated
Whether the newest value of corresponding pre-set level is accurate.
Wherein, sliding time window refers to the time range that point is constituted from start time point to the end time.Wherein, at this
In this implementation, start time point is the minimum generation time in the not accurate generation time stamp of value of corresponding pre-set level
Stamp, end time point are that log obtained above postpones any one generation time stamp for being more than or equal to start time point in table.
For example, minimum time stamp in current not accurate generation time stamp for 15 points 25 seconds 20 minutes, log postpones in table
Generation time stamp be respectively 15 points 26 seconds 20 minutes, 15 points 27 seconds 20 minutes, 15 points 28 seconds 20 minutes and 15 points 29 seconds 20 minutes, then terminate
Time point can postpone any one generation time stamp in this four generation time stamps in table for log.
In this step, each generation time for being included to detection sliding time window is needed to stab corresponding pre-set level
Whether value is accurate.For example, including 3 generation time stamps in sliding time window, in this step, need to detect this 3 productions
Whether the value of the corresponding pre-set level of life timestamp is accurate.
In the present embodiment, any one generation time in sliding time window is stabbed, detects generation time stamp
The whether accurate process of the value of corresponding pre-set level be it is identical, for convenience introduce, the present embodiment is with time slip-window
For any one generation time stamp (target generation time stamp) in mouthful, introduces and detect the corresponding default finger of generation time stamp
The whether accurate process of target value.
Specifically, Fig. 4 is that the embodiment of the present application discloses a kind of detection target generation time and stabs corresponding pre-set level
The whether accurate method of newest value.
The detection process is the process that a circulation executes, when reaching with default detection when multiple detections at a length of interval
Between in a detection time when, triggering execute one-time detection process, until certain execute detection process in judge to meet
When preset condition, then it represents that the value that the target generation time stabs corresponding pre-set level is accurate.
Wherein, each detection process all corresponds to a detection time, requires to obtain pre-set level in each detection process
Value (calculated result) in the calculated pre-set level of last time value, that is, obtain pre-set level newest value,
For convenience, calculated result acquired in each detection process is known as result data.
Since the present embodiment is the process that a circulation executes, for convenience, when by according to detection after arriving first
Between the sequence that arranges be known as detection time sequence, will be arranged according to detection time from rear acquired result data is arrived first
To sequence be known as result data sequence.
Specifically, may comprise steps of:
S401, when reaching the target detection time, it is corresponding default that target generation time stamp is obtained from result data table
The newest value of index.
In the present embodiment, for convenience, any one generation time stamp in sliding time window is known as mesh
Mark generation time stamp.In this step, multiple detections at a length of interval when the initial value of target detection time is with default detection
First detection time in time, first detection time can be set by the user.
In the present embodiment, it is being counted every time due to having recorded pre-set level according to the sequencing of calculating in result data table
It is corresponding default to obtain target generation time stamp in this step from result data table for obtained value (calculated result)
The newest value of index.
Since the calculating process for the value for calculating pre-set level includes calculating at least once, a calculating is calculated every time
As a result, also, the detection process of the data accuracy of the calculating process and the present embodiment of the value of pre-set level is mutually independent
Process.Therefore, in this step, the newest value of acquired pre-set level is off current sensing time last time and is counted
The value of calculating, for convenience, when the newest value of acquired pre-set level is known as result data, i.e. current detection
Between acquired result data.
S402, the newest value for calculating pre-set level acquired in the newest value last time for the pre-set level that this is obtained
Between difference value, obtain the first difference value.
In the present embodiment, this refers to current sensing time, the last time refer in history detection time with current detection
Temporally adjacent detection time.It is there is no the last time, i.e., pre- acquired in last time if the present embodiment is to execute for the first time
If the newest value of index is sky.
In this step, difference reflection be the adjacent pre-set level obtained twice newest value between variation degree.
Specifically, difference value can be difference or change rate, wherein difference be this obtain pre-set level newest value with it is upper
Difference between the newest value of the pre-set level once obtained；Change rate is difference and this is obtained and the last time obtained
The ratio at interval.Certainly, in practical applications, difference can also be other content, and the present embodiment is not to the particular content of difference
It limits, as long as difference can reflect between the newest value that the adjacent target generation time obtained twice stabs corresponding pre-set level
Variation degree.
For convenience, the pre-set level newest value and the last time of this pre-set level obtained obtained it is newest
Difference value between value is known as the first difference value.
S403, it is based on detection time sequence, the preceding preset quantity detection time obtained in current sensing time is counted respectively
Obtained difference value.
When this step is to execute for the first time, calculated separately in the preceding preset quantity detection time of current sensing time
The difference value arrived is sky.
S404, judge whether to meet preset condition, if it is satisfied, then S405 is executed, if conditions are not met, then executing S406.
In this step, preset condition includes: that the first difference value and acquired preset quantity difference value are both less than pre-
If threshold value, wherein preset threshold is the same numerical value.
If this step is to execute for the first time, a difference is only existed, which is exactly the first difference value, acquired
Difference value is sky.Acquired difference value can be regarded as infinity, at this point, when executing this step for the first time, judging result one
It is set to and is unsatisfactory for preset condition.
It should be noted that the preset condition in this step is a kind of implementation, in practice, those skilled in the art
Member can preset condition determines according to actual conditions particular content.
S405, determine target generation time stab corresponding pre-set level newest value it is accurate.
In this step, determine target generation time stab corresponding pre-set level newest value it is accurate.
S406, determine that target generation time stabs the newest value inaccuracy of corresponding pre-set level.
In this step, it is inaccurate for determining that target generation time stabs the corresponding newest value of pre-set level.
S407, the target detection time is updated.
In the present embodiment, whether the newest value that detection target generation time stabs corresponding pre-set level is accurately circulation
It carries out, intercycle is default detection duration, i.e. detection time is distributed according to default detection duration.For example, default detection
Shi Changwei mono- minute, detection time be followed successively by 14 points 30 minutes, 14 points 31 minutes, 14 points 32 minutes ....
In this step, the target detection time is the minimum time for being greater than current sensing time in preset multiple timestamps
Stamp, wherein current sensing time is the target detection time reached in S401 in this implementation procedure.For example, this is executed
In the process the target detection time in S401 be 14 points 30 minutes, then in this step, the target detection time be 14 points 31 minutes so that
Reach 14: 31 timesharing in the time, continues to execute S401.
Sampling process due to calculating pre-set level in practice is likely to occur failure, and calculating task is caused to generate accumulation,
When calculating task generates accumulation, acquired preset quantity difference value and first difference value are judged in S404
Respectively less than preset threshold still stabs the process that corresponding data calculate the value of pre-set level for the target generation time, should
There is also uncalculated data in the corresponding data of target generation time stamp, i.e., the newest value of current obtained pre-set level
It is not the final calculation result that the generation time stabs corresponding all data；But judge to meet preset condition according to S404,
I.e. the target generation time stab corresponding pre-set level newest value it is accurate；Therefore, to target generation time stamp pair
Accurately the accuracy of this testing result is lower for the newest value for the pre-set level answered.
The newest value of corresponding pre-set level accurate detection result is stabbed for the target generation time in order to improve
Accuracy, detection target generation time stabs the whether accurate process of newest value of corresponding pre-set level, as shown in Figure 5.
In the detection process, in each implementation procedure, in addition to including acquired preset quantity difference in preset condition
Different value and first difference value are respectively less than except preset threshold, further include that there is no be not carried out in generated calculating task
Calculating task.It is respectively less than pre- in acquired preset quantity difference value and the first difference value i.e. in some detection time
If threshold value, and there is no the calculating tasks being not carried out in generated calculating task, then and target generation time stamp is corresponding pre-
If the newest value of index is accurate in the detection time, otherwise, it determines the target generation time stabs corresponding pre-set level most
New value is in detection time inaccuracy, when reaching the target detection time, continues to execute according to above-mentioned thinking, should until meeting
When preset condition, it is determined that the newest value that the target generation time stabs corresponding pre-set level is accurate.
Specifically, the process may comprise steps of:
S501, when reaching the target detection time, it is corresponding default that target generation time stamp is obtained from result data table
The newest value of index.
S502, the newest value for calculating the pre-set level that this is obtained and the newest of pre-set level acquired in the last time take
Difference value between value obtains the first difference value.
S503, it is based on detection time sequence, the preceding preset quantity detection time obtained in current sensing time is counted respectively

In this step, preset condition includes: that acquired preset quantity difference value and the first difference value are respectively less than
Preset threshold, and there is no the calculating tasks being not carried out in generated calculating task.
If the case where being unsatisfactory for preset condition includes:
The first situation: there is the calculating task being not carried out in generated calculating task；
Second situation: the calculating task being not carried out, and acquired present count are not present in generated calculating task
A difference value and the first difference value are measured not all less than preset threshold.
S505, determine target generation time stab corresponding pre-set level newest value it is accurate.
S506, determine that target generation time stabs the newest value inaccuracy of corresponding pre-set level.
S506, the target detection time is updated.
In this step, if the calculating task being not carried out is not present in generated calculating task, but it is acquired
Preset quantity difference value and the first difference value be not all less than preset threshold, then when the detection of detection trigger process next time
Between for according to it is default detection duration distribution multiple detection times in, greater than current sensing time minimum time stab.For example, working as
Preceding detection time be 14 points 30 minutes, preset detection when it is 1 minute a length of, then the target detection time be 14 points 31 minutes.For the side of description
Just, will in generated calculating task there is no the calculating task that is not carried out, and acquired preset quantity difference value and
First difference value not all less than preset threshold in this case, the detection time determined be known as first object detection when
Between, using the first object detection time as the target detection time.
If there is the calculating task being not carried out in generated calculating task, i.e., what is obtained in this implementation procedure is default
The newest value of index may be the newest value of the pre-set level obtained in last time implementation procedure, therefore, even if acquired
Preset quantity difference value and the first difference value are respectively less than preset threshold, can not ensure that target generation time stamp is corresponding pre-
If the newest value of index is accurate.
Due to that can determine that delay duration, i.e., the calculating task accumulated after the delay duration could calculate completion, because
This, determines that the detection time that detects next time of triggering is in preset multiple detection times stamps, from current sensing time to pusher
Minimum time stamp after the slow delay duration, for convenience, is known as the second target detection for the detection time determined
Time continues to execute detection when reaching the target detection time using the second target detection time as the target detection time
Process.
Specifically, determining that the method for determination for triggering the detection time of detection process next time includes:
A1, to calculate current sensing time to postpone the time point after the delay duration be to stab the reference time.
A2, it is detected in multiple detection times that duration is distributed from default, determines the minimum time for being greater than reference time stamp
Stamp was the second target detection time.
For example, current sensing time be 14 points 30 minutes, when detection, is 2 minutes a length of, and when delay is 3 minutes a length of, then the second mesh
Mark detection time be 14 points 34 minutes.
The utility model has the advantages that in the present embodiment, being parsed to the data that data producer in message queue generates and right
The data that any generation time stabs after corresponding parsing are successively calculated, and are obtained the generation time and are stabbed corresponding pre-set level
Multiple values；The value that corresponding pre-set level is stabbed based on the generation time is detected the generation time and stabs corresponding pre-set level
Newest value it is whether accurate.Specifically, in each detection process, obtaining generation time stamp by the detection process of circulation
The newest value of corresponding pre-set level determines the first difference value based on acquired newest value, judges that the generation time is stabbed
Whether the newest value of corresponding pre-set level is accurate.
Wherein, judge whether accurately a kind of mode may include: acquired preset quantity to the newest value of pre-set level
A difference value and the first difference value are respectively less than preset threshold.
In practice, in the program failure that the process of the value of corresponding pre-set level is stabbed in calculating generation time,
So that there is the calculating task being not carried out in generated calculating task, so that the calculating task of accumulation is produced, at this point, due to
Program mal causes the newest value of the pre-set level repeatedly obtained during repeated detection to be the same median, this
When, judge that acquired preset quantity difference value and the first difference value are respectively less than preset threshold, but pre-set level
Newest value is inaccurate.In order to improve pre-set level newest value accurate detection result accuracy, the present embodiment removes
The acquired preset quantity difference value of judgement and the first difference value are respectively less than outside preset threshold, while also judging to have generated
Calculating task in the presence or absence of the calculating task that is not carried out, only in acquired preset quantity difference value and described the
One difference value is respectively less than preset threshold, also, there is no when the calculating task being not carried out in generated calculating task, determining should
The newest value that generation time stabs corresponding pre-set level is accurate, at this point, testing result accuracy with higher.
In order to improve detection efficiency, when there is the calculating task being not carried out in generated calculating task, this is calculated not
Total duration needed for the calculating task of execution, and the second target detection time after current sensing time postpones the total duration into
Capable detection process next time.
