Silencing Not Working in Sensu Version 6.12

Silencing Checks or Entities Not Working in Sensu Version 6.12

Expected Behavior

When silencing a check or entity, no alerts should be received for the silenced items.

Current Behavior

Despite silencing checks or entities using either through Web UI or sensuctl, alerts continue to be received. This issue has been tested on Sensu version 6.12. This behaviour with earlier versions has not been verified.

Steps to Reproduce (for bugs)

1. Silence a check or entity via the Web UI or sensuctl.
2. Trigger the check to execute again.
3. Observe that alerts are still generated despite the silence configuration being active.

same didn't work in UI as well as command when I tried to silent for month it keep on saying maximum duration allowed
really after upgrade of 6.12 my entire slack is noisy.

Tried for Month

# sensuctl silenced create -s entity:admin-02 -c check-cpu -e 31536000 -r "Silencing CPU check until 2024-12-31 22:00:00"
Error: Threshold reached: silenced crossed maximum duration allowed

Tried for 15days

sensuctl silenced create -s entity:admin-02 -c check-cpu -e 31536000 -r "Silencing CPU check until 2024-12-15 22:00:00"
Error: Threshold reached: silenced crossed maximum duration allowed

Tried for a day :(

# sensuctl silenced create -s entity:admin-02 -c check-cpu -e 31536000 -r "Silencing CPU check until 2024-12-02 22:00:00"
Error: Threshold reached: silenced crossed maximum duration allowed

In UI I could see the same error

Hi @sjkeerthi

The values need to be configured in the backend.yml file on all backend nodes. Afterward, restart the Sensu backend cluster nodes one by one to apply the changes.

The values for max-silenced-expiry-time-allowed and default-silenced-expiry-time should be set as follows:

max-silenced-expiry-time-allowed: 1440m
default-silenced-expiry-time: 1440m

Note:- m stands for minute

We need to increase the value as per our requirement and it should in minutes

We are currently in the process of releasing the documentation, and it will be available soon. In the meantime, please feel free to reach out if you need any further assistance.

Many Thanks,
