"Eventually this customer has had enough. They leave. This represents both a sizable blow to revenue and a scathing indictment of your product’s reliability at scale. But, on the bright side, both MTTR and MTBF benefit enormously! That’ll look great on the quarterly slide deck." (~700w)

sage words from @danslimmon on how to better develop you/your team's #o11y theory by getting practical practice #monitorama #observability
-
“Name your metrics, alerts and dashboards with the language you would use if you were having a conversation about the system at lunch, not the cryptic defaults or uuid hostnames” ~ @danslimmon #monitorama #monitorama24 #observability
-
We’ve all heard the definition for observability, but, who is one? What is involved in determining? ~ @danslimmon presenting “No observability without theory” You need a theory of the system to build valid inferences

Great piece by Dan Slimmon about assigning incidents scores and how it doesn't make sense. As someone who has had to do this a bunch in my career, his approach makes a ton more sense to me than the current way most companies do it.

@thisismissem @sgf "blame" is not the same thing as "assigning responsibility".
A good red flag for this is teams that say "We do #blameless #postmortems by not naming anyone in the postmortem".
No! You know you have a blameless postmortem culture when you *can* name people in postmortems without it causing problems.
This can be exceptionally hard to achieve, but it's worth it.
