Hello Cephers, A very happy new year to you all! I wanted to enable LTTng tracepoints for a few tests with infernalis and configured Ceph with the –with-lttng option. Seeing a recent post on conf file options for tracing, I added these lines: osd_tracing = true osd_objectstore_tracing = true rados_tracing = true rbd_tracing = true However, I am unable to see LTTng tracepoints within ceph-osd. I can see tracepoints in ceph-mon though. The main difference with respect to tracing between ceph-mon and ceph-osd seems to be TracepointProvider and I thought the addition
in my config file should do the trick but that didn’t change anything. I do not know if this is relevant but I also checked with lsof and I see ceph-osd is accessing the lttng library as is ceph-mon. Did anyone come across this issue and if so, could you give
me some direction on this? Thanks a lot for your help! Aakanksha |
