Metrics
At /metrics, each node exposes its metrics in the Prometheus format.
Each node serves /metrics on its administration port, in the Prometheus exposition format. The route asks for a client certificate of a user with the clusterMonitor role.
| Metric | What it measures |
|---|---|
teseladb_up | The node is running. |
teseladb_ranges | Ranges with a replica on this node. |
teseladb_range_applied_index{range} | Last applied entry of each replica of the node. |
teseladb_range_leader{range} | Whether this node is the leader of that range. |
The REST API and the MCP server add, per route and per tool, requests, a latency histogram, errors by code and open SSE streams. No label carries user data.
