Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention be used to the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Suitable environment
Situation for video flowing and signaling data all transmit by IP network, because the real time data changes in flow rate is larger, can't judge the variation of service condition accurately.For the situation that video flowing and signaling data transmit by different links, for example the interactive TV business, can judge the variation of corresponding service state by the variation of signaling traffic.For the network configuration of centralized deployment, all user request need to be processed by Centroid, and Centroid is all passed through in the transmission of signaling data, and the variation of the signaling traffic by Surveillance center's node can judge the service operation state of the whole network.For the interactive TV operation system, at first user's order request passes through page server, if operation system breaks down, the Signalling exchange on user and backstage just there will be extremely, for example can't build and flow successfully normally.The user can continue attempt to send the stream request of building, and the stream request of building of a large amount of failures causes signaling traffic to be increased sharply, and the variation by flow can judge whether normal operation of operation system.
The implementation of signaling traffic monitoring principle
By real-time port flow, monitor to realize the monitoring of signaling traffic, port flow Refresh Data rate is 1 time/second, so just can guarantee real-time and the accuracy of port flow data, provides safeguard for by signaling traffic, judging the service operation state.By the signaling flow spirogram, can see intuitively the real-time change of signaling traffic, signaling traffic is slowly to increase or slow decreasing under normal circumstances, online user's quantity difference of different periods, user's order request number is variant, causes the variation of signaling traffic.The signaling flow spirogram of normal condition as shown in Figure 2.
Can see that what in Fig. 2, monitor is the total flow of port sending and receiving, signaling traffic is increasing slowly, and the signaling data of representation page is normal, and interactive TV operation system overall operation is normal.
For the situation that the interactive TV operation system breaks down, user's order request can be increased sharply at short notice, and a large amount of order request can't be processed in time, causes the unexpected variation of signaling traffic.The signaling flow spirogram of failure condition as shown in Figure 3 and Figure 4.
For the unexpected situation about increasing of signaling traffic, can tentatively be judged as service system running state occurs abnormal, can't normally carrying out alternately of signaling, cause the signaling traffic surge, as shown in Figure 3, if the amplitude of variation of signaling traffic surpasses 50Mbyte/min, mean that Signalling exchange is abnormal, abnormal conditions appear in service operation, need to check the related service system; Situation for signaling traffic reduces suddenly, as shown in Figure 4, can tentatively be judged as the signalling link fails, cause can't normally carrying out alternately of signaling, signaling traffic die-offs, and needs to check the log information of the network equipment, failure judgement device port and link.
The judgement service condition
The real time data of Signalling exchange has reflected the real-time status of service operation, can judge by the variation of monitoring signaling traffic whether the service operation state is normal.For signaling traffic, monitor in real time by the signaling flow spirogram, the variation of port flow has reflected the real-time change of signaling data, by the monitoring to signaling traffic and analysis, judges the running status of business, and as shown in Figure 5 and Figure 6, main method is as follows:
1, observe the situation of change of signaling traffic, the situation that whether has flow suddenly to increase or die-off, occur that flow suddenly increases and goes to step 2, occurs that flow is die-offed to go to step 5, and the unchanged expression business of data on flows is normal;
2, check in back-stage management server and have or not the information of reporting an error, by execution, check the script realization, if the information of reporting an error goes to step 3, if back-stage management server is without the information of reporting an error, continue to check whether the interactive TV door can normally access, if can not normally access and go to step 4, if the interactive TV door can normally be accessed, the variation of signaling traffic data is caused by the internal data distribution, is normal phenomenon;
3, check the information that reports an error in back-stage management server, prompting failure judgement reason and coverage according to the daily record that reports an error, fault that can immediate recovery is by restarting the service recovery business of controlling play-on-demand program and Signalling exchange, fault that can not immediate recovery is recovered business by enabling standby back-stage management server, has operated rear inspection service operation normal;
4, check the ruuning situation of interactive TV portal server, check the service operation situation of each portal server, program request daily record failure judgement reason and coverage according to portal server, fault that can immediate recovery by by the fault portal server from server cluster, bringing out the recovery business, after taking out of, restart the fault portal server and restart related service, check after service operation normally and bring server cluster into, fault that can not immediate recovery is recovered business by enabling standby portal server, has operated rear inspection service operation normal;
5, signaling traffic occurs die-offing into the signalling link problem, the switch log information of collecting in checking monitoring, according to daily record check result failure judgement equipment or non-working port, the fault detail information that the relevant device port is arranged in log information, by the restarting equipment port or enable the backup network device recovery system and normally move, check that service operation is normal;
Normally whether 6, inspection business operation, goes to step 1 and continues to observe.
Shown in step 3: (1) logs in back-stage management server and collects the current daily record that reports an error, and checks according to the daily record that reports an error the information that stream reports an error of building; (2) if build overtime the reporting an error of stream, at first check whether back-end data library storage readwrite performance is normal, if database storage readwrite performance is poor, cause to build to flow and ask to process in time, cause that to build stream overtime, this type of fault can immediate recovery, need to carry out the database server switching, switched rear inspection database running status, checked that service operation is normal; If database storage readwrite performance is normal, the Signalling exchange information of on-demand session in the stream daily record is built in inspection, it is overtime or build the reason that runs off and to lose that stream is built in analysis, because a large amount of, build the stream request queue and wait for and cause that to build stream overtime, this type of fault can immediate recovery, now needs to restart the service processes of being responsible for building stream, releasing resource, check that the service processes running status is normal, check that the Signalling exchange of building on-demand session in the stream daily record is normal, check that service operation is normal; (3) if can't find reporting an error of program resource, program state not normal the renewal causes finding program resource, and this type of fault can immediate recovery, need to restart the program resource management server, checks that program state is normal, checks that service operation is normal; (4) if system file damages or other report an error, this type of fault can not immediate recovery, need to enable standby back-stage management server, checks that the back-stage management server log update is normal, checks that service operation is normal.
Shown in step 4: (1) at first checks portal server program request log update situation, if the program request daily record can not normal refresh, whether the chkdsk space is normal, if certain portal server journal disk insufficient space can cause that Set Top Box program request daily record can't normally write, door can't normally be accessed, this type of fault can immediate recovery, now need first this portal server from the portal server cluster, taking out of, then by manual mode, remove history log information, it is normal that the chkdsk log space recovers, audit log refreshes normally, the inspection portal accesses is normal, confirm that service operation is normal, if disk space is normal, this type of fault can immediate recovery, needs first this portal server, from the portal server cluster, taking out of, then to restart this portal server, and audit log refreshes normally, checks that portal accesses is normal, and the confirmation service operation is normal, (2) if the program request log update is normal, check whether the time shift program data are synchronous normal, if portal server time shift program data do not have normal synchronized, this type of fault can immediate recovery, need first this portal server from the portal server cluster, taking out of, then to recover the time shift program data synchronous by restarting server, checks the time shift program normal refresh, the inspection portal accesses is normal, confirms that service operation is normal, (3) if time shift program is synchronously normal, inspection door user data storehouse running status, if door data storehouse abnormal state or other information that reports an error, this type of fault can not immediate recovery, need to enable standby portal server, check the portal server normal operation, check that service operation is normal.
As shown in Figure 7, the order request of Set Top Box arrives portal server by the network equipment to interactive service program request flow chart, carries out Signalling exchange with back-stage management server, and the monitoring of signaling traffic is that the port flow by switch carries out monitoring in real time.If the Signalling exchange of Set Top Box occurs abnormal, the port flow of switch just there will be variation, just can judge the running status of business by the variation of monitoring signaling traffic.Because the variation of signaling traffic is in real time monitoring, thus can pinpoint the problems fast, for judgement and the solution of fault provides basis, for the stable operation of online operation system provides safeguard.
