Gary Yao commented on FLINK-16588:
----------------------------------
What would speak against this is that there are more specialized tools such as
[nagios|https://support.nagios.com/kb/article.php?id=770] to monitor stats of
the underlying hardware.
[~chesnay] What do you think?
> Add Disk Space metrics to TaskManagers
> --------------------------------------
>
> Key: FLINK-16588
> URL: https://issues.apache.org/jira/browse/FLINK-16588
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Affects Versions: 1.10.0
> Reporter: Thomas Wozniakowski
> Priority: Minor
>
> Hi,
> We have recently switched to the RocksDB state backend. We are scraping
> Taskmanager metrics from the REST endpoints to watch for memory and CPU
> issues, but we currently have no good way to get the remaining disk space, so
> we have no way of knowing when RocksDB is going to run out of space for state
> storage.
> How plausible is it to add something like a {{State.FreeStorageBytes}} metric
> or something similar to the standard TaskManager metrics set?
> Thanks,
