Hi, Whenever I restart or check the logs for OSD, MON, I get below warning message.. I am running a test cluster of 09 OSD's and 03 MON nodes. [ceph-node1][WARNIN] libust[3549/3549]: Warning: HOME environment variable not set. Disabling LTTng-UST per-user tracing. (in setup_local_apps() at lttng-ust-comm.c:375)
In short: this is harmless, you can ignore it. liblttng-ust tries to listen for control commands from lttng-sessiond in a few places by default, including under $HOME. It does this via a shared mmaped file. If you were interested in tracing as a non-root user, you could set LTTNG_HOME to a place that was usable, like /var/lib /ceph/. Since ceph daemons run as root today, this is irrelevant, and you can still use lttng as root just fine. Unfortunately there's no simple to silence liblttng-ust about this.
