Thomas Wozniakowski commented on FLINK-16588:
---------------------------------------------
Hey [~gjy],
I take your point, but as a user of Flink I try to stay as close as possible to
the vanilla versions (best documented, best supported, etc). For us, that means
using the official Flink docker images. On Amazon, AWS does not provide any way
to observe the remaining disk space from OUTSIDE a container, so that only
leaves us one option: monitor from inside. From our perspective that can be
achieved 2 ways:
# Fork the official docker image and add something like nagios to it
# Upgrade Flink so it's included in the official docker image by default
We obviously prefer the second option because then we're not maintaining our
own image :)

> 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,
