Hi all, I'm stuck with a similar problem with cephfs-shell for octopus (https://docs.ceph.com/en/octopus/cephfs/cephfs-shell/#cephfs-shell). I can't figure out where to get it from. Its not part of the octopus container and also seems not to be available through the octopus repos. Anyone here who can point me to an installation procedure?
Thanks and best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Zach Heise (SSCC) <[email protected]> Sent: 19 October 2022 21:25:14 To: Neeraj Pratap Singh; [email protected] Subject: [ceph-users] Re: Getting started with cephfs-top, how to install Thank you for the reply, Neeraj - solved! I was just going off of the document at https://docs.ceph.com/en/quincy/cephfs/cephfs-top/ - I did not see a specified terminal emulator listed, but yes, after switching my Secure Shell program to XTerm, that seems to have fixed it. Also, now 'ceph fs perf stats' shows a "wall of text" in an unformatted way, which is what I assume cephfs-top is formatting so nicely in its python script. I appreciate the help, and I will make an edit request to that document adding the information I have learned from you and Xiubo, so other relative novices like myself will perhaps be able to fix these issues on their own in the future!

Lots of enhancements are being done in cephfs-top recently. Will suggest to use latest build for better results. And regarding your `use_default_colors()` error, it looks like there some issue with the unsupported terminal emulator.

Flipping that bit to 1 then re-running yum update then yum install cephfs-top solved that problem. However, that leads to a second question then - after running the required command to create the fstop user with $ ceph auth get-or-create client.fstop mon 'allow r' mds 'allow r' osd 'allow r' mgr 'allow r' as the instructions specify, and adding the file ceph.client.fstop.keyring with the relevant key to /etc/ceph on the node in question (which the instructions do not specify and I will make a github edit later), I am getting an error: "exception: use_default_colors() returned ERR" Beyond that, it seems like the system that cephfs-top needs to work, perf stats, has no data in the output fields? ceph01.ssc.wisc.edu<http://ceph01.ssc.wisc.edu>> ceph fs perf stats {"version": 1, "global_counters": ["cap_hit", "read_latency", "write_latency", "metadata_latency", "dentry_lease", "opened_files", "pinned_icaps", "opened_inodes", "read_io_sizes", "write_io_sizes"], "counters": [], "client_metadata": {}, "global_metrics": {}, "metrics": {"delayed_ranks": []}} I activated ceph fs perf stats yesterday, so by this point I should have data in the stats, unless there is a problem elsewhere?

According to this page: https://docs.ceph.com/en/quincy/cephfs/cephfs-top/ - cephfs-top is the simplest way to do this? I enabled 'ceph mgr module enable stats' today, but I'm a bit confused about what the best way is to get the cephfs-top package to use this perf stats. If you are building code from source then you should run it just by: [ceph/build]$ ./src/tools/cephfs/top/cephfs-top You can also find the main/quincy/pacific builds for different distro pacakges under [1] and their artifacts are made available under [2]. [1] https://shaman.ceph.com/builds/ceph/ [2] https://shaman.ceph.com/repos/ceph/ Thanks! - Xiubo The ceph doc page linked above just mentions "cephfs-top is available as part of cephfs-top package" but it does not list what repo is required to access this. Anyone using cephfs-top themselves, and know the missing parts of this document that should be added? -- Zach Heise _______________________________________________ ceph-users mailing list -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]> _______________________________________________ ceph-users mailing list -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]> -- Neeraj Pratap Singh He/Him/His Associate Software Engineer, CephFS [email protected]<mailto:[email protected]> Red Hat Inc. <http://www.redhat.com> [https://financialit.net/sites/default/files/red_hat_5.png] _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
