Monitoring Metrics

Pinot provides metrics out of the box so that you can monitor every aspect of performance and robustness of the Pinot cluster. Most of the metrics are available either at table level or instance level. There are three main categories of metrics:

  • Gauge – A single value at any point in time

  • Meter – Rates of the metric per unit of time

  • Timer – Record durations and can be used to fetch average duration per unit of time, percentile values, minimum or maximum values, etc.
