[Joshua Fan]

Hi,all

Frequently, for some cluster, there is  no data from Task Manager in UI, as the picture shows below.

but the cluster and the job is running well, just no metrics can be got.

anything can do to improve this?

Thanks for your assistance.

Hi All

came into new situations, that the UI can show metric data but the data remains the same all the time after days. So, there are two cases, one is no data in UI at all, another is dead data in UI all the time.

when dig into the taskmanager.log, taskmanager.error, taskmanager.out, there is nothing unnormal found.

anyone can give some hints?

Yours sincerely

Joshua

Hi Joshua,

Looks like a bug, the UI parsing we saw in Flink 1.5.0 and 1.6.0 is normal. 

Please feel free to create a JIRA issue.

In addition, I suggest you upgrade your Flink version.

Thanks, vino.
