Hello,
The whole test-suite for noble-proposed has completed and all tests have
passed. The results can be seen here:
https://github.com/canonical/ceph-charms/actions/runs/19547255675?pr=120
(Please ignore the COS integration test, it isn't related to this SRU and it's
been broken for a while now).
As for the tests regarding LTTNG, the following procedure was used:
- After deploying a Ceph cluster with 19.2.3, we install the lttng binaries:
> sudo apt install lttng-tools
- Next, we run the lttng daemons:
> lttng-sessiond --daemonize
- We can then list the available trace points:
> lttng list -u
UST events:
-------------
PID: 14531 - Name: /usr/bin/ceph-osd
ust_baddr_statedump:soinfo (loglevel: TRACE_DEBUG_LINE (13)) (type:
tracepoint)
osd:do_osd_op_post (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
osd:do_osd_op_pre_unknown (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
mutex:lock_exit (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
mutex:lock_enter (loglevel: TRACE_DEBUG_LINE (13)) (type: tracepoint)
osd:do_osd_op_pre_copy_from (loglevel: TRACE_DEBUG_LINE (13)) (type:
tracepoint)
osd:do_osd_op_pre_copy_get (loglevel: TRACE_DEBUG_LINE (13)) (type:
tracepoint)
- We can now create a session, and begin tracing:
> lttng create
Session auto-31240637-925731 created.
> lttng enable-event -u -a
All UST events are enabled in channel channel0
> lttng start
Tracing started for session auto-31240637-925731
- Next, we'll generate some activity on the Ceph cluster. We'll use
`rados bench` but any other type of I/O over objects can be applied:
> sudo rados -p data bench 10 write
- After the above is done, we'll stop tracing and verify the output:
> lttng stop
Waiting for data availability.
Tracing stopped for session auto-31240637-925731
> lttng view | head
[18:42:17.027535265] (+0.000001786) mutex:lock_enter: { cpu_id = 0 }, { addr =
0x1fc2408, name = "SimpleMessenger::DispatchQeueu::lock" }
[18:42:17.027535846] (+0.000000581) mutex:lock_exit: { cpu_id = 0 }, { addr =
0x1fc2408, name = "SimpleMessenger::DispatchQeueu::lock" }
[18:42:23.027538829] (+0.000000576) mutex:lock_exit: { cpu_id = 0 }, { addr =
0x205a610, name = "OSD::recovery_tp::lock" }
Finally, we can note that if we disable tracing and run the `rados
bench` program again, no tracing output will be generated.
