Intermittently, the rsp probe will report something as missing. Usually a disk, sometimes swap or other metric.
Often this is just a single alert, then the fault clears, sometimes the fault persists for tens of samples before clearing.
Traced one such alert by setting log level=5 on the rsp probe and found that the result of the 'df' command clearly included all filesystems, yet immediately after the probe alerted that one was missing.
