Technical Field

Monitoring software for business systems has also been introduced by many internet companies.
For companies with complex service systems and network environments, more analysis software is used to understand the network operation conditions in order to make the network operate healthily. A considerable amount of analysis software analyzes its own network by configuring the corresponding network service (the specific network task configured by the user). The analysis can greatly improve the operation maintenance capability and the fault handling efficiency of the network and effectively reduce the fault time.

For example, for a banking system, business data of the banking system is acquired in real time through a probe, the business data is acquired from the probe through an interface and stored locally, and the business data is displayed based on the business data stored locally. There is a delay in the process of acquiring traffic data from the probe over the interface, however, such that when, for example, traffic data is presented for a period of time (e.g., 9:00-10:00), for 10: data of 00, due to the delay, at 10:00, stored locally 10: the data of 00 is empty, which causes great trouble if it is displayed at the front end.

The embodiment of the application provides a data display method, which comprises the steps of acquiring network node data at preset time intervals, and storing the acquired data in a local database; calculating a time offset and storing the time offset in the local database, wherein the time offset indicates a difference between a time at which the acquired traffic is stored in the local database and a time at which the traffic is acquired; acquiring data from the local database according to time parameters and service parameters, wherein the time parameters comprise display starting time and display ending time; and calculating an actual presentation deadline from the time parameter and the time offset. Through the processing scheme of the application, the data display effect is improved.
Next, a data presentation method according to an embodiment of the present application will be described in detail with reference to the drawings.
Referring to fig. 1, a data display method provided in an embodiment of the present application includes:
s100: network node data is acquired at predetermined time intervals and the acquired data is stored in a local database.
In the embodiment of the present application, data may be acquired in a network node, such as a router, of a network system through a network probe, for example, and the acquired data may include traffic, a traffic type, and the like, for example. And the acquired data may be stored locally for subsequent transactions such as presentation, analysis, and the like.
In the present embodiment, the predetermined time interval may be, for example, 5min, 10min, or any other time interval, and the network node data acquired in the time interval is stored in the local database for subsequent traffic.
S200: a time offset is calculated and stored in the local database, wherein the time offset indicates a difference between a time at which the acquired traffic is stored in the local database and a time at which the traffic is acquired.
Generally, for a data acquisition device such as a probe, data acquisition can be performed manually, but in the process of storing the data acquired by the probe in a local database, for example, data needs to be acquired from the probe through a special interface, and the adoption of the interface and a transmission path causes a time difference between the acquisition of the data and the local storage of the data. In the embodiment of the present application, a difference between a time at which data acquired by a network probe is stored in a local database and a time at which the traffic is acquired is defined as a time offset, and the time offset is stored in the local database.
For example, for a time interval of 5min, the network probe may perform real-time acquisition in the time period, and then the data acquired by the network probe is transmitted to the local database through an interface or the like, and there is a delay in the transmission process, so that for example, for the network probe, 10: 00-10: 05 data collected during this time period, it may be between 10:06 is stored in the local database, the time offset can be assumed to be 1min, and the time offset (1 min) is stored in the local database together with the data acquired during the time period.
S300: and acquiring data from the local database according to time parameters and service parameters, wherein the time parameters comprise display starting time and display ending time.
In the process of data or service exhibition, what needs to be exhibited is data in a specific time period, such as exhibition 10: 00-11: data in time period 00. That is, in the embodiment of the present application, the time parameter indicates a time period in which the service needs to be shown, and includes a show start time and a show deadline. For example for a time parameter < 10:00, 11: 00>, which shows a start time of 10:00, and exhibits a cutoff time of 11: 00. it should be understood that the presentation start time and the presentation deadline may not be fixed time points, but may be variable amounts, for example, the presentation deadline may refer to the current time, so that the current business situation can be presented in real time.
The service parameter may be, for example, a parameter such as an IP address, so that service data corresponding to the IP address can be acquired according to the IP address.
In the case that the time parameter and the service parameter (for example, IP) are known, the service data of the port corresponding to the IP address within the time parameter can be obtained from a local database, for example. Although the form of acquiring the service data is specifically recited in the embodiment of the present application, the embodiment of the present application is not limited to this, and the time parameter and the service parameter may be combined to acquire the service data in other manners.
S400: and calculating the actual display deadline according to the time parameter and the time offset.
As described above, since there is a delay in acquiring the service data from the probe to be stored in the local database, if the display is performed in real time, the service data corresponding to the current time point may be empty, which may cause an abnormal display.
To solve this problem, in the embodiment of the present application, the actual presentation deadline is also calculated from the time parameter and the time offset. That is, at the time of presentation, presentation is not performed exactly in accordance with the set time parameter, but the deadline of presentation is set with reference to the time delay as well.
Specifically, for example, the presentation deadline in the set time parameter is 10: 02, and at 5min intervals from 9:00 acquires the data of the network node, in this case, if the data is transmitted at 10: when the time shift amount at 00 is less than 2min, the time shift amount is set to 10: and when 02, the display can normally show that 10:00, but if at 10: when the time offset at 00 is greater than 2min, 9: 55-10: 00 the time period has not been stored in the local database and thus cannot be normally presented. In this case, in the present embodiment, the presentation deadline is recalculated. Specifically, for example, in the range of 10: and under the condition that the time offset at 00 is less than 2min, setting the actual display deadline to be 10:00, if the ratio of 10: and when the time offset of 00 hours is more than 2min, setting the actual display deadline to be 9:55, thereby avoiding display anomalies.
According to the data display method, display abnormity possibly caused by data delay is considered, so that the actual display deadline time is set according to the time offset, the display integrity is guaranteed, and the display effect is improved.
According to a specific implementation manner of the embodiment of the application, after the actual display deadline is obtained, data is displayed according to the actual display deadline. Specifically, after the actual display deadline is obtained, only the business data from the display start time to the actual display deadline is displayed during display, thereby ensuring the integrity of the display.
According to a specific implementation manner of the embodiment of the present application, the service parameter may be an IP address, and in this case, when data is acquired from the local database, service data corresponding to the IP address and within the set time parameter may be acquired from the local database. Thus, desired data can be obtained conveniently. It should be understood that although in the embodiment of the present application, the service parameter is described as an IP address, the service parameter may also be other parameters such as an object type and a traffic size.
Referring to fig. 2, according to a specific implementation manner of the embodiment of the present application, the calculating a time offset and storing the time offset in the local database in step 200 includes:
s201: and sequentially obtaining the accumulated time offset when the network node data is acquired according to the time sequence.
For example, for a time period of 9:00-10:00, and a predetermined time interval of 5min, time offsets at time points of 9:05,9: 10..10:00, etc. are obtained in sequence. The time offset obtained in this case is a cumulative time offset, e.g., for time 9:10, the time offset obtained at the change point is an overall time offset for the period of time 9:00-9: 10.
S202: and obtaining the absolute time offset of each acquisition time interval according to the accumulated time offset.
As described above, for each time node, the time offset directly obtained by the time node is the accumulated time offset, and the delay reflected by the accumulated time offset is also the delay of all the services before the time point, so that the time delay in the acquisition time interval with finer granularity cannot be accurately described. Thus, in the present embodiment, an absolute time offset is obtained for each acquisition time interval.
Specifically, for example, the accumulated time offsets at 9:05,9: 10..10:00 are t1, t2, and t3., respectively, the absolute time offset of the acquisition time interval can be obtained by subtracting the previous accumulated time offset from the next accumulated time offset. For example, for an acquisition time interval <9:05,9:10>, the absolute time offset is t2-t 1.
S203: and storing the network node data acquired at the time interval and the corresponding absolute time offset in the local database.
After the absolute time offset is obtained by step S202, the network node data collected for the time interval and the corresponding absolute time offset are stored in a local database.
By the scheme, the time delay of each service can be analyzed at a finer granularity, so that help is provided for subsequent adjustment of display strategies and search of delay reasons.
Referring to fig. 3, according to a specific implementation manner of the embodiment of the present application, the calculating an actual display deadline according to the time parameter and the time offset includes:
s301: and acquiring the display deadline in the time parameter.
In general, the presentation deadline may be a time considered to be set, e.g., 10:00, or may be a current time of change.
S302: and obtaining the time for acquiring the network node data at the previous time of the display deadline according to the display deadline and the time interval.
For example, in the case where the presentation deadline is set to 10:04 and the time interval is set to 5min, the time at which the network node data was acquired the previous time of the presentation deadline at this time is 10: 00. Alternatively, in a case where the presentation deadline is set to the current time and the time interval is set to 5min, assuming that the current time is 10:03, the time at which the network node data was acquired the previous time at which the presentation deadline was present is 10:00, and in a case where the current time is 10:06, the time at which the network node data was acquired the previous time at which the presentation deadline was present is 10: 05.
S303: and determining the actual display deadline according to a comparison result of the sum of the time of obtaining the network node data at the previous time and the corresponding time offset and the display deadline.
Specifically, in order to ensure the integrity of the display, when the sum of the time of obtaining the network node data last time and the corresponding time offset is earlier than the display deadline, the time of obtaining the network node data last time is taken as the actual display deadline. For example, when the current time is 10:03 and the time for acquiring the network node data at the previous time of displaying the deadline is 10:00, if the time offset corresponding to the time 10:00 is less than 3min, the time 10:00 is taken as the actual display deadline.
And when the sum of the time for obtaining the network node data in the previous time and the corresponding time offset is later than the display deadline, determining the actual display deadline according to a comparison result of the sum of the time for obtaining the network node data in the previous time and the corresponding time offset and the display deadline. For example, in the case that the current time is 10:03 and the time of obtaining the network node data at the previous time of showing the deadline is 10:00, if the time offset corresponding to the time 10:00 is greater than 3min, that is, the sum of the time 10:00 of obtaining the network node data at the previous time and the corresponding time offset (e.g., 4 min) is later than the showing deadline, the actual showing deadline is determined according to the comparison result of the sum of the time (9: 55) of obtaining the network node data at the previous time and the corresponding time offset (e.g., 4 min) and the showing deadline (10: 03), and specifically, when the comparison result is earlier than the showing deadline (10: 03), the time of obtaining the network node data at the previous time is taken as the actual showing deadline.
That is, the time of the previous acquisition of the network node data and the corresponding time offset are sequentially determined until the sum thereof is less than the presentation deadline.
According to a specific implementation manner of the embodiment of the present application, the network node data may include a plurality of network node data, and the time offset includes a time offset of each of the plurality of network nodes. That is, the traffic data stored in the local database may be data acquired from a plurality of network nodes, in this case, including time offset data of the respective network nodes. In this case, referring to fig. 4, according to a specific implementation manner of the embodiment of the present application, the obtaining data from the local database according to the time parameter and the service parameter includes:
s401: and determining the network node related to the service parameter.
In order to obtain data from the local database in a targeted manner, the network nodes associated with the traffic parameters are first determined. Specifically, when the service parameter is an IP address, the network node corresponding to the IP address is obtained in the local database, and then the data corresponding to the network node is obtained.
S402: and acquiring the time offset of the network node related to the service parameter.
In this embodiment, a difference between a time at which the acquired data of each network node is stored in the local database and a time at which the data is acquired is defined as a time offset of the network node.
S403: and comparing the time offset of the network node related to the service parameter and taking the maximum time offset as the time offset.
Since the data corresponding to the traffic parameter may come from multiple network nodes, in this case, only the time offsets of the network nodes related to the traffic parameter need to be compared and the maximum time offset obtained. Therefore, when the service data related to a plurality of network nodes are displayed, the time offset of each network node does not need to be calculated independently during displaying, the actual display deadline of each node is obtained, the normal displaying of the service data can be met only by taking the maximum time offset as the time offset, and the calculation resources are saved.
Referring to fig. 5, according to a specific implementation manner of the embodiment of the present application, the calculating a time offset includes:
s501: obtaining time offsets of the plurality of network nodes.
S502: the time offsets of the plurality of network nodes are compared.
S503: taking a maximum time offset among the time offsets of the plurality of network nodes as the time offset.
For the same service, the delays at different nodes may be different due to the intermediate service process, and in this case, in order to ensure the display integrity of the same service, only the maximum time offset among the time offsets in each network node needs to be considered, so that the whole process of the service can be completely displayed. Thus, the amount of calculation at the time of presentation can be reduced.
