Metrics Reference
This page lists the metrics generated by kdb Insights Enterprise. See Monitoring for details on how metrics are captured, stored and presented.
Each component generates a range of metrics. With metrics enabled on a component, kdb info, memory and CPU metrics are generated.
Database
The kdb Insights Database publishes performance metrics regarding the storage and querying of data.
See the following links for details on the metrics available: - Storage. - Query.
Reliable Transport
The Reliable Transport, also known as a kdb Insights Stream, publishes status and performance metrics.
Details on the metrics available are located here.
The metrics are published by default, but can be disabled by setting the environment variable RT_EXPORT_METRICS="0".
