    Understood. I am in UK but use Hetzner in DE, and don't have any performance issues.

    @jpodner I had the same issue. Solved it by following the instruction on this page to extend my LVM space.

    Btw, I applied the changes of the system.js according to the changelog to solve this problem in my environment until the update is available. So at least for myself this Post could be set to "solved".

    @d19dotca to be honest, I think can be quite debatable, for example say three apps shape a rough sine curve across the time period, there would not be an easy visual winner. But what is also important here, currently we use what the graph library gives us and reworking this for little value is currently not worth while 🙂

    @girish said in Cloudron 7.3.2: "Analyze Disk" doesn't do anything:

    The code is not handling CIFS/SSHFS volumes correctly.

    was not, is now?

    @d19dotca ext4 is the filesystem type in this case from your root / partition and ext4 has a feature of reserved blocks for the root user. Other disks may or may not be ext4 like for volumes or backup.

    Over the past few days, I've been getting alerts that apps are running out of memory that typically have had no issues after the past few days. The System Info / System Memory isn't showing any spikes in RAM usage. I'm still trying to run this down but having some trouble doing so and need to keep digging.

    @robi Good point ... I think it's this way because one way to expand boxdata/appdata/platformdata is using symlinks. Then there's volumes , backups. So, it was easier to filter out by known filesystems.

    @mehdi said in Disk IO Tracker:

    just trying to periodically write stuff and checking the performance, as suggested, would not be great IMO, as it would 1/ be influenced by what's already running on the system 2/ wear out SSDs for little benefit

    Agreed, there are better ways, the example was more for the output or datapoints.

    Aspects of BPF tools make this light on resources, but there's a whole stack of tools down the line, including 'iolatency'.

    @girish said in Count of allocated memory:

    We can improve our graphs section.

    You can say that again! 😛

    I find the memory usage graph to be pretty useless. A table with the values would be much more useful.

    The full stack trace is:

    The last line gives a hint that the graphite file is corrupt. So, I removed all the whisper files in /home/yellowtent/platformdata/graphite/whisper/collectd/localhost/df-sdc1 and graphs seems to work after that.

    @atridad Maybe a good idea to check the health of the hard disk ? Also, since we hit the systemd issue on the same server.

    @rmdes yes, I am not sure why. It doesn't happen in any of our demo servers or managed services. Quite strange. It could also be that maybe others have hit it but have not noticed it (since it only causes a CPU spike..) but clearly it's a bug since it's been fixed upstream.

    @stoccafisso I think I am able to reproduce this in one of our managed Cloudrons. Looking into the fix.

    @girish I guess I'm wondering though why it'd say "Not available yet"... is that because I had restarted the server a few hours earlier? I don't normally notice that though when I restart, it usually still shows data. Is it possible there's a bug here?

    If the restarts are losing that data, then I'd think that's a bug, right, if it shows for some services but not all? To me that makes it seems like it's either not completing properly when it runs and that could maybe explain why it shows values for some but not all, or perhaps it's losing data when it should be remembering it. My gut tells me there's a bug here. Or am I way off?

    I guess it's okay since we have a workaround to run that command when it happens, my brain is just wondering why it happened in the first place and how it could be prevented.
