This page describes Grafana dashboards for YDB. For information about how to install dashboards, see Setting up monitoring with Prometheus and Grafana.

DB status

General database dashboard.

Actors

CPU utilization in an actor system.

Name Description
CPU by execution pool (us) CPU utilization in different execution pools across all nodes, microseconds per second (one million indicates utilization of a single core)
Actor count Number of actors (by actor type)
CPU CPU utilization in different execution pools (by actor type)
Events Actor system event handling metrics

gRPC

Name Description
Requests Number of requests received by a database per second (by gRPC method type)
Request bytes Size of database requests, bytes per second (by gRPC method type)
Response bytes Size of database responses, bytes per second (by gRPC method type)
Dropped requests Number of requests per second with processing terminated at the transport layer due to an error (by gRPC method type)
Dropped responses Number of responses per second with sending terminated at the transport layer due to an error (by gRPC method type)
Requests in flight Number of requests that a database is simultaneously handling (by gRPC method type)
