- Around line 221-253: The two code paths for recording container exit in the
LastTerminationState branch are inconsistent: in the !alreadyRecorded branch the
ExitCode == 0 path uses monitorapi.Info while the other (existing) path uses
monitorapi.Error; change the new branch to use monitorapi.Error instead of
monitorapi.Info so both paths use the same severity. Locate the !alreadyRecorded
block that constructs intervals with
containerStatus.LastTerminationState.Terminated and replace the monitorapi.Info
call in the ExitCode == 0 branch with monitorapi.Error so the interval level
matches the existing behavior.

Inconsistent interval level for exit code 0 between new and existing code paths.
The alreadyRecorded guard logic correctly prevents double-counting by comparing FinishedAt timestamps.
However, there's an inconsistency in interval levels:
- New code (line 243): Uses
monitorapi.InfowhenExitCode == 0 - Existing code (line 271): Uses
monitorapi.ErrorwhenExitCode == 0
This means a successful container exit (code 0) could be logged as Info or Error depending on which code path fires first, leading to inconsistent monitoring data.
Please align the interval levels—either both should use Info for successful exits, or both should use Error.
🔧 Proposed fix to align with existing behavior (use Error)
} else {
intervals = append(intervals,
- monitorapi.NewInterval(monitorapi.SourcePodMonitor, monitorapi.Info).
+ monitorapi.NewInterval(monitorapi.SourcePodMonitor, monitorapi.Error).
Locator(monitorapi.NewLocator().ContainerFromPod(pod, containerName)).
Message(monitorapi.NewMessage().
Reason(monitorapi.ContainerReasonContainerExit).🔧 Alternative fix: Update existing code to use Info for exit code 0
If Info is semantically correct for successful exits, update line 271 as well:
} else {
intervals = append(intervals,
- monitorapi.NewInterval(monitorapi.SourcePodMonitor, monitorapi.Error).
+ monitorapi.NewInterval(monitorapi.SourcePodMonitor, monitorapi.Info).

This wasn't really new code. It just puts the old code in a new scope.

@xueqzhan, you're right — looking at the diff more carefully, the monitorapi.Info for exit code 0 was already present in the original code before this PR. The change only wrapped the existing logic in the if !alreadyRecorded guard without altering the interval levels. My comment was incorrect. Sorry for the noise!
