If none of the above alarm type conditions is satisfied, the alarm type is other problems.
And acquiring the basic attribute reported by the current set top box from the message, and recording the basic attribute value, wherein the basic attribute comprises the information of the region where the current set top box is located, the manufacturer of the set top box, the license plate party of the program, the model of the set top box, the Url of the program and the like.
And storing the obtained alarm types, the preset alarm type conditions met, the unique codes of the set top box in the message, the report time of the viewing message and the alarm message, the basic attribute values and other information into an HBase database.
Determining whether the message is a viewing message or an alarm message to determine the number of viewing users and alarm users, and storing the time obtained by adding the basic attribute value and the conversion into MongoDB, wherein the information stored in MongoDB is shown in the following table 1:
list one
The number of the alarm users in the table is obtained by statistics according to basic attribute values such as license plate side codes, city codes, manufacturer codes, time, set top box models, program URLs and alarm messages with the same alarm types, and the number of the audience users is obtained by statistics according to license plate side codes, city codes, manufacturer codes, time, set top box models and audience messages with the same program URLs, for example, a line record example of MongoDB is as follows:
the record represents that license plate party code is CNTV, city code is Wu Hou Ou in Chengdu, manufacturer code is beacon, manufacturer code is CM201-2, program URL is "http:// 117.146.223.183/888888/16// 26919469. Ts", viewing user number in the period of 2020040210 is 264, and alarm user number of alarm type is 9600 for CDN problem alarm.
The data in MongoDB are classified according to different combination relations between five fields of license plate coding cpcode, city coding area code, manufacturer coding stbcode, manufacturer coding model and program URLprogram, namely basic attribute value combination and alarm type, and meanwhile, alarm coverage rate of different time datetime based on the above conditions is obtained by using the number of alarm users/number of viewing users, for example, alarm data of a home local area network forming an urban Wu Houou is obtained through calculation, and is expressed in JSON format for expressing the following data clearly, and can also be expressed according to formats such as objects:
the above data shows that in Chengdu Hou Ou, the alarm type is home LAN problem, the alarm coverage is 0.352 at time 2020040210, the alarm coverage is 0.354 at time 2020040110, the alarm coverage is 0.337 at time 2020040211, and the alarm coverage is 0.341 at time 2020040211.
And intercepting the hour field, namely the last two bits of time, for example 2020040211, from the obtained alarmcoverage, intercepting the hour field to obtain 11, collecting the same formed historical alarm coverage rate of the hour field, for example 11 in the hour field, hou Ou in Chengdu city, 0.337,0.331 in the alarm type of historical alarm coverage rate set formed in the home local area network problem, taking the average value as the basic attribute combination, and collecting the historical alarm coverage rate of 11 under the alarm type.
Historical alarm coverage rates obtained by combining different basic attributes and alarm types are stored in MongoDB as shown in Table 2.
TABLE 2
| 1 | cpcode | String | License plate square code |
| 2 | areacode | String | City code |
| 3 | stbcode | String | Vendor code |
| 4 | datetime | Int | Time (hours: HH), |
| 5 | model | String | set top box model |
| 6 | warntype | String | Alarm type |
| 7 | coverage | Double | Alarm coverage |
Taking MongoDB Beijing Kogyo CDN problem alarm coverage rate of 10 points of the problem alarm problem as an example of 0.353, the stored data are as follows:
through the processing flow of the message uploaded by the set top box, the server can acquire the alarm type, the basic attribute value, the message uploading time and related data such as the alarm coverage rate and the like of the message according to the combination of the alarm type and the basic attribute value, so as to be used for generating the comprehensive alarm. The specific flow of the comprehensive alarm generation method of this embodiment is shown in fig. 1.
And step 101, obtaining the total number of audience users and the total number of alarm users according to the messages meeting the preset conditions. The message is obtained from a plurality of set top boxes in a preset time period, and comprises an alarm message and a viewing message.
In one example, in the step of preprocessing the data, after processing the message data, storing the corresponding data in an HBase database, wherein the HBase stores alarm types, alarm types conditions of message matching, a set top box in the message uniquely encodes deviceid, viewing messages and alarm message reporting time, the message meeting preset conditions can be searched from the HBase database, the number of viewing users of each message meeting the preset conditions is accumulated, the total number of viewing users of the message meeting the preset conditions is obtained, and similarly, the total number of alarm users of each message meeting the preset conditions is accumulated, so that the total number of alarm users of the message meeting the preset conditions is obtained.
In one example, the preset condition includes: with the same alarm type and the same attribute value combination.
Taking city codes and alarm types as examples, the city codes are Beijing Kogyo areas, the alarm types are CDN alarms, the data of the alarm types and the city codes are searched in an HBase database, the preset time period is 20 minutes, and the total number of viewing users and the total number of alarm users from the current time period to 20 minutes before the current time period are obtained.
And 102, acquiring real-time alarm coverage rate according to the total number of the audience users and the total number of the alarm users.
In one example, the total number of alert users obtained in step 101 is divided by the total number of viewing users to obtain the real-time alert coverage.
And step 103, judging whether to generate comprehensive alarms according to the real-time alarm coverage rate and the historical average alarm coverage rate, wherein the historical average alarm coverage rate is obtained according to the total number of audience users and the total number of alarm users of the historical messages meeting the preset conditions.
In this embodiment, the historical average coverage rate may be obtained according to the data stored in the mongo db database, and the step of preprocessing the data by the mongo db is already described, which is not described herein.
For example, if the current time is between zero point and one point, obtaining a city code from a MongoDB database as a Beijing Korea, and the alarm type is CDN alarm, averaging a historical alarm coverage rate set from zero point to 1 point, obtaining a historical average alarm coverage rate, and comparing the historical average alarm coverage rate with a real-time alarm coverage rate.
In addition, in one example, if the real-time alert coverage is greater than the historical average alert coverage, generating a composite alert; and if the real-time alarm coverage rate is not greater than the historical average alarm coverage rate, judging whether to end the comprehensive alarm according to the historical comprehensive alarm condition. The historical comprehensive alarm condition refers to whether the comprehensive alarm which has the same alarm type, basic attribute and time as the real-time alarm coverage rate exists in the range and the current time is not finished.
Taking the real-time alarm coverage rate from zero to 1 point as an example, taking the real-time alarm coverage rate of the Beijing Kogyo area as the CDN alarm, ending the comprehensive alarm if the real-time alarm coverage rate is not greater than the historical average alarm coverage rate and the comprehensive alarm which is not ended exists in the current range, deleting the comprehensive alarm information which is related to the non-ended in the HBase, such as a basic attribute value, time, alarm type and set top box associated with the alarm, wherein the deleted comprehensive alarm information in the example is as follows: and in the morning sun area of Beijing city, CDN problem alarming, time and associated set top box models, if the real-time alarming coverage rate is larger than the historical average alarming coverage rate, generating comprehensive alarming, and if no finished comprehensive alarming exists in the current range, storing comprehensive alarming information into an HBase database. When the finished comprehensive alarm does not exist in the current range, the comprehensive alarm information is stored in the database to avoid redundancy of the data stored in the database.
If the CDN problem alarm is generated in the Beijing Korea according to the discovery, maintenance personnel can analyze the related network of the Beijing Korea according to the alarm type conditions which are met by specific equipment associated with the CDN problem alarm and HBase, and the fault analysis for a set top box can be made, so that the alarm problem of the set top box can be conveniently solved.
The embodiment is a one-time comprehensive alarm generation process, and different ranges, namely different basic attribute value combinations and comprehensive alarms of different alarm types, can be determined according to the data of the database.
In addition, the database and the frame, the components and the like used in the embodiment are only for easy understanding, and do not limit the technical scheme.
The embodiment of the invention stores the audience alarm number in a classifying way and judges the comprehensive alarm of the set top box according to the historical alarm coverage rate, and the alarm of the associated set top box is analyzed instead of only analyzing the alarm of a single set top box, so that the reason for the occurrence of the alarm of the set top box is conveniently obtained.
A second embodiment of the present invention relates to a comprehensive alarm method. The second embodiment is substantially the same as the first embodiment, and differs mainly in that: in a second embodiment of the present invention, a history alert coverage collection is obtained according to the total number of viewing users and the total number of alert users of a history message satisfying a preset condition; removing abnormal values from the alarm coverage rate set; and acquiring historical average alarm coverage rate according to the alarm coverage rate set from which the abnormal value is eliminated.
