extensions.watchdog.profile_action.v3.ProfileActionConfig¶

Configuration for the profile watchdog action.

{
  "profile_duration": "{...}",
  "profile_path": "...",
  "max_profiles": "..."
}

profile_duration: (Duration) How long the profile should last. If not set defaults to 5 seconds.

profile_path: (string, REQUIRED) File path to the directory to output profiles.

max_profiles: (uint64) Limits the max number of profiles that can be generated by this action over its lifetime to avoid filling the disk. If not set (i.e. it’s 0), a default of 10 will be used.
