It looks like your PR touches production code but doesn't add or edit any test code. Did you consider adding tests to your PR? 🦉 Hoot! I am a Blathers, a bot for CockroachDB. My owner is dev-inf. |

This change is |
| StaticLabels: metric.MakeLabelPairs(metric.LabelQueryType, "started-select"), | ||
| Essential: true, | ||
| Category: metric.Metadata_SQL, | ||
| HowToUse: "This high-level metric reflects workload volume. Monitor this metric to identify abnormal application behavior or patterns over time. If abnormal patterns emerge, apply the metric's time range to the SQL Activity pages to investigate interesting outliers or patterns. For example, on the Transactions page and the Statements page, sort on the Execution Count column. To find problematic sessions, on the Sessions page, sort on the Transaction Count column. Find the sessions with high transaction counts and trace back to a user or application.", |

Can you say anything more specific about started vs other metrics that would be helpful here?
I'm also not sure this metric is "essential". Most customers use the executed metrics to count QPS so we should justify why they should also pay attention to these.

Good point. I searched Slack and found only 2 threads that explicitly mentioned using the started metrics for troubleshooting:
- https://cockroachlabs.slack.com/archives/C02119Q1G05/p1623169882143700?thread_ts=1623161302.135100&cid=C02119Q1G05
- https://cockroachlabs.slack.com/archives/C0713QV7XHP/p1714432731834549
Additionally, the started metrics was introduced in #37264, which also introduced the executed metrics as a claimed more useful one.
So maybe we should close it for now until receiving explicit ask for this feature?

Removed the "Essential:true" field per offline discussion.
