Using following code:
check file mysqld-error-log with path /var/log/mysqld.log ignore match "MY-010956" ignore match "MY-010957" if match "Warning" then alert if match "ERROR" then alert
I still get notifications for errors that should be ignored:
Description: content match:
2020-06-26T04:42:30.206476Z 5 [Warning] [MY-010956] [Server] Invalid replication timestamps: original commit timestamp is more recent than the immediate commit timestamp. This may be an issue if delayed replication is active. Make sure that servers have their clocks set to the correct time. No further message will be emitted until after timestamps become valid again.
2020-06-26T04:42:31.342138Z 5 [Warning] [MY-010957] [Server] The replication timestamps have returned to normal values.
