In the case of consecutive intervals within the same bar, the end dates in tooltip are not 5 minutes rounded.

DETAILS

All the intervals are differentiated by one second

This logic is applied in https://github.com/openshift/monitoring-plugin/blob/main/web/src/components/Incidents/utils.ts#L192

. Line 207: Initial nodata interval ends one second before the first timestamp

• Lines 219-220: When severity changes, the interval ends one second before the new timestamp:

• Line 263: createNodataInterval creates a nodata gap from previousTimestamp + 1 to currentTimestamp - 1:

• Line 231: Final nodata interval starts one second after the last timestamp:

This ensures: No overlapping intervals Clear boundaries between intervals Gaps are represented as nodata intervals

For example, if you have timestamps at 100, 200, and 300:

Interval 1: [100, 199, 'critical']

Interval 2: [200, 299, 'warning']

Interval 3: [300, 399, 'info']

Each interval ends one second before the next one starts, creating a 1-second separation.

Proposed Fix
A possible fix on the UI side could be to not changing the logic how intervals are calculated but rounding the text displayed in the tooltip
