Seems good to me. You should also look at the query metrics at the historical and the broker. https://druid.apache.org/docs/latest/operations/metrics/#historical https://druid.apache.org/docs/latest/operations/metrics/#broker Also druid 27.0 has query from deep storage which should further help you running queries on segments not loaded on the historicals,

Thanks @Karan Kumar! Why look at broker metrics? I should only be looking at historical node metrics, right?

For general slowness. Since user impacting stuff is better monitored in the brokers
