Personal rage thread on #Monitoring vs. #Observability. Courtesy of this delineastion: "Monitoring is telling you your systems are broken, Observability is being able to ask why?"

Telling me a system is broken is *worthless* if I can't ask it why it's broken.
"Yo, your shit's broken" has ALWAYS been BAD monitoring.
At times, it may be the only monitoring we have, but it's not the end goal.

Every time I see #Monitoring vs #Observability I wonder if they knew sysadmins could program before #DevOps became a thing. I've been a sysadmin for almost 20 yrs. On day 1, I thought "running the same commands over and over again is dumb, here's some #Perl."
