Joshua Boniface cfeba50b17 Revert "Return to all command-based Ceph gathering" ... This reverts commit 65d14ccd92. This was actually a bad idea. For inexplicable reasons, running these Ceph commands manually (not even via Python, but in a normal shell) takes 7 * two orders of magnitude longer than running them with the Rados module, so long in fact that some basic commands like "ceph health" would sometimes take longer than the 1 second timeout to complete. The Rados commands would however take about 1ms instead. Despite the occasional issues when monitors drop out, the Rados module is clearly far superior to the shell commands for any moderately-loaded Ceph cluster. We can look into solving timeouts another way (perhaps with Processes instead of Threads) at a later time. Rados module "ceph health": b'{"checks":{},"status":"HEALTH_OK"}' 0.001204 (s) b'{"checks":{},"status":"HEALTH_OK"}' 0.001258 (s) Command "ceph health": joshua@hv1.c.bonilan.net ~ $ time ceph health >/dev/null real 0m0.772s user 0m0.707s sys 0m0.046s joshua@hv1.c.bonilan.net ~ $ time ceph health >/dev/null real 0m0.796s user 0m0.728s sys 0m0.054s		2021-07-10 03:47:45 -04:00
