Metric name | Type | Labels | Description |
client.connection.creations | Sum | broker_id | Total number of broker connections made. |
client.connection.count | Gauge | Current number of broker connections. | |
client.connection.errors | Sum | reason | Total number of broker connection failures. Label ‘reason’ indicates the reason: disconnect - remote peer closed the connection. auth - authentication failure. TLS - TLS failure. timeout - client request timeout. close - client closed the connection. |
client.request.rtt | Histogram | broker_id request_type | Average request latency / round-trip-time to broker and back. request_type is the protocol request type CamelCase name as specified in the Kafka protocol definition. |
client.request.queue.latency | Histogram | broker_id | Average request queue latency waiting for request to be sent to broker. |
client.request.queue.count | Gauge | broker_id | Number of requests in queue waiting to be sent to broker. |
client.request.success | Sum | broker_id request_type | Number of successful requests to broker, that is where a response is received without no request-level error (but there may be per-sub-resource errors, e.g., errors for certain partitions within an OffsetCommitResponse). |
client.request.errors | Sum | broker_id request_type reason | Number of failed requests. Label ‘reason’ indicates the reason: timeout - client timed out the request, disconnect - broker connection was closed before response could be received, error - request-level protocol error. |
client.io.wait.time | Histogram | Amount of time waiting for socket I/O writability (POLLOUT). A high number indicates socket send buffer congestion. |
