info-center statistic-suppress enable

Function

The info-center statistic-suppress enable command enables suppression of statistics about consecutive repeated logs.

The undo info-center statistic-suppress enable command disables suppression of statistics about consecutive repeated logs.

The info-center statistic-suppress disable command disables suppression of statistics about consecutive repeated logs.

By default, suppression of statistics about consecutive repeated logs is enabled.

Usage Guidelines

Usage Scenario

In the system, service modules generate logs and control the volume of generated logs. The information center processes the received logs.

A large number of repeated logs are generated in a short time in some scenarios, for example, when ARP and VRRP are enabled. This wastes both the storage space and CPU resources. Generally, users do not want to view the repeated logs. You can run the info-center statistic-suppress enable command to suppress statistics on consecutive repeated logs so that the system can still record other logs.

Logs that are generated consecutively and with the identical log ID and parameters can be regarded as repeatedly generated logs.

Precautions

Statistics about repeatedly generated logs are first output at the 30th seconds from the time the first log is output, and then statistics about repeatedly generated logs are output at the 120th seconds. After being output two times, statistics about repeatedly generated logs are output every 600 seconds.

By default, once receiving a log, the information center outputs the log. If the information center receives repeatedly generated logs within a period, it outputs the number of these logs and will output logs only when it receives a new log (a log with a different log ID). For example, a module sends logs to the information center in the sequence of A1(T1) A2(T2) A3(T2) B1(T3) B2(T4) B3(T4) C1(T5) C2(T6) A4(T7) B4(T8) B5(T8) B5(T8) B7(T9) A5(T9) B8(T10) D1(T11) A6(T11) A7(T12) A8(T12) A9(T13) A10(T14) A11(T15) A12(T16) A13(T17) A14(T18) B9(T18). A1 to A14 are the same; B1 to B9 are the same; C1, C2 and D1 are different from others; T1 to T18 are sequence numbers. The log information output by the information center is as follows:

T1:A1
T3(1): last message repeated 2 times
T3:B1
T5: last message repeated 2 times
T5:C1
T6:C2
T7:A4
T8:B4
T9(1): last message repeated 3 times
T9:A5
T10:B8
T11:D1
T11:A6
T13(2): last message repeated 3 times
T18(2): last message repeated 5 times
T18:B9

Logs of the service module received by the information center show that:

Statistics about repeatedly generated logs are output when either of the following conditions is met:
- The next log is a different log, as shown in (1).
- The time period (every 30 seconds, 120 seconds, and 600 seconds) for outputting log statistics expires, as shown in (2).
Each time the statistics are output, the service module clears the count and starts counting again. For example, during the period from T11 to T18, log A is generated 9 times.
The information center outputs logs in the same sequence the logs are generated, making the trace of information and scenario easy.

Logs with the sequence being A B A B A B A B are alternate logs; therefore, the info-center statistic-suppress enable command is unable to suppression the statistics about these logs.
