These are not parameters, but monitoring metrics. Refer to: INSPECTION_RESULT | PingCAP 文档中心
The data is collected from Prometheus. You can search the official documentation for the specific meaning of the metrics.

So how should these alerts be handled? Do we need to adjust anything?

| username: 小龙虾爱大龙虾 | Original post link

No need to handle it, this is all performance-related. As long as your business is fine, it’s okay.

Will this affect performance?

Why was there no alarm reported before?

These are all warnings, no need to handle them.

TiDB’s alerts are numerous and detailed. Sometimes, it feels overwhelming, and without careful study, it’s really hard to manage.

There won’t be any issues if you don’t check :stuck_out_tongue:. I see that the alerts are all monitoring metrics, such as cache hit rate. Could it be because the test environment is not being used much?

It does not affect usage, ignore it.

| username: 烂番薯0 | Original post link

Ignore this.

When the cluster does not have performance or failure issues, it is advisable to keep some parameters at their default values. It is not recommended to modify them arbitrarily if you are not sure, as it is unnecessary.
