Execution Highlighting
Every invocation of a function gets a unique execution ID, and all of that one request's lines share it. Because serverless runs many requests at once, their lines interleave by timestamp. Execution highlighting tints lines by execution so you can follow one request through the interleaving - without hiding the rest.
Choosing a mode
Choose a mode from View ▸ Execution Highlighting, or from the ••• menu in a GCP pane's toolbar (just left of the filter field), which also offers Help to open this page:
- None - no tint.
- Highlight Selected - tints only the lines that share the selected line's execution. Click a line to follow its request; quiet and on-demand.
- Highlight All - gives every execution its own color from a 12-color palette, so concurrent requests read as distinct colored bands.
The setting is global and works in single panes, layouts, and the time-merged view. Only GCP lines are tinted; SSH and local lines stay neutral. Lines without an execution ID (e.g. some Cloud Run / scheduler entries) aren't tinted.
Filtering to one execution
To see only one request's lines instead of just tinting them, open the inspector for one of its lines and click Filter Execution. The pane then shows just that execution. Clear it with Esc, by right-clicking and choosing Clear Execution Filter, or with the inspector's Clear Filter button - and you're returned to the line you started from.
Both live on GCP & Firebase Sources, which covers the rest of what a Cloud Logging entry carries.
