High-cardinality metrics can increase resource use
Prometheus is a useful option for operations teams monitoring instrumented services. Start with a small set of exporters and verify metric names, labels, and scrape intervals before building alerts. Start with a small, representative task so you can check the results before extending the setup.
Choose retention and label conventions deliberately, then test alert rules against known incidents instead of every short-lived fluctuation. Consider the practical trade-off: not a general log store.
