| 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 |
Download the actors.json file with the Actors dashboard.
CPU
CPU utilization in execution pools.
| Name | Description |
|---|---|
| CPU by execution pool | 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 each execution pool |
| Events | Event handling metrics in each execution pool |
Download the cpu.json file with the CPU dashboard.
gRPC
gRPC layer metrics.
| 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) |
