Cobalt System Metrics Daemon

The Cobalt System Metrics Daemon starts early after boot on a Fuchsia system and periodically measures several system metrics and logs the values to Cobalt. The daemon is not part of the Cobalt telemetry system but rather a client of it that happens to be owned by the Cobalt team.

If you would like to start measuring a new system metric on Fuchsia you might consider adding the instrumentation to this daemon. That would be appropriate if

  • the metric is about the Fuchsia system as a whole
  • there is no other Fuchsia component where it would be more appropriate to add the instrumentation
  • the instrumentation periodically polls some measurement
