info-center rate-limit threshold

You can run the info-center rate-limit threshold command to set the maximum number of logs with the same log ID that the information center can process every second. The information center monitors the number of logs that are generated every second under the same log ID. When the number of logs that are generated every second under the same log ID exceeds the threshold in the monitoring period, the information center decides that too many logs are generated and suppresses its log processing rate by processing only the conforming traffic (logs within the threshold) and discarding the non-conforming traffic (logs exceeding the threshold). When the number of logs that are generated every second under the same log ID falls below the threshold and remains below the threshold for five monitoring periods, the information center removes the suppression.

By default, the information center processes a maximum of 30 logs with the same log ID in every second. In certain application scenarios, by default, the information center needs to process more than 50 logs with the same log ID in every second. You can set thresholds for logs with different log IDs. Generally, the default threshold is recommended.

• If the threshold is too low, some logs may be discarded.
• If the threshold is too high, the information center cannot identify the log ID under which too many logs are generated.

• If the threshold value1 specified by the parameter byinfoid infoID or bymodule-alias modname alias differs from the threshold value0 specified globally, value1 takes effect.
• During a software upgrade, if the threshold is configured in the old version, but the new version does not support the specified log module and alias, the threshold configuration of the specified log module and alias will be automatically cleared after the upgrade.
