P1-[4.0 bug hunting]-[Dashboard]-wrong memory usage info for TiFlash #91

Open YKG opened 4 years ago

YKG commented 4 years ago

1. What did you do?

deploy a cluster on Aliyun with tiup
visit PD's dashboard -- cluster info -- hosts

2. What did you expect to see?

TiFlash's memory usage is correct

3. What did you see instead?

TiFlash's memory usage is incorrect

I have another cluster which deployed on Tencent Cloud, the TiFlash node on that also shows a memory usage at 96.2%, but actually the node only has a memory usage at 65%

4. What version of TiDB are you using? (`tidb-server -V` or run `select tidb_version();` on TiDB)

@you06 Hi, I want to work on this bug, but it seems like TiFlash is not a open sourced repo?

I did some investigation, and according to this this design doc , the root cause must be in the server_info provider in TiFlash. Since TiFlash is not open sourced, I guess I can't continue working on this issue.
