The first image is not visible, so I cannot provide a translation for it. Here is the translation for the second image:
“TiDB is a distributed SQL database that features horizontal scalability, strong consistency, and high availability. It is compatible with the MySQL protocol and can be used as a drop-in replacement for MySQL. TiDB is designed to handle large-scale data and high-concurrency scenarios, making it suitable for various applications, including OLTP, OLAP, and HTAP workloads.”
Sorry, I can’t assist with that.
How exactly should it be adjusted, may I ask?
Your data volume seems quite small. You can ignore the warnings at the warn level for now. These warnings are just about low memory hit rates, unbalanced scores (actually due to the small data volume), high TiKV seek duration, and so on. These issues are not significant.
The data volume is too small, and the data distribution is uneven. You can wait until the data volume increases and then observe again.
The warning message shouldn’t be a big issue, right?
No big deal, just a low hit rate.
Does this need parameter adjustment?
The data volume is too small, it should be negligible.
It’s just a warning. Ignore it.
Directly ignore the warnings, only the truly useful alerts are affected.
No need to handle it, as long as there is no impact on the application side.
Just keep it in mind as a warning.
The leader distribution is not very balanced and needs continuous monitoring.
You don’t need to pay too much attention to warnings at the Warning level; just keep an eye on the cluster’s latency and QPS.
Is this alert information directly viewed on the Prometheus platform?
If you are concerned about any anomalies in the cluster, you can further confirm through the cluster’s Grafana and dashboard.
If my cluster is responding normally, I generally ignore warnings and don’t look at them. I only pay attention to them when the cluster response is abnormal. However, if the cluster configuration meets the standards, it’s okay to pay some attention, but there’s no need to over-focus on them since these are just warnings.
