Metrics Collection
SPIRL components can optionally collect metrics and expose them in a Prometheus metrics endpoint.
SPIRL Agent
Metrics collection is disabled by default and can be toggled by setting telemetry configuration in the helm chart values.
# Telemetry configuration
telemetry:
# Whether to enable telemetry
enabled: false
# Metrics collectors configuration
collectors:
# gRPC metrics collector configuration
grpc:
# Whether to emit latency metrics. Time histogram metrics for gRPC servers and clients will be emitted if true.
# Since it is bad practice to have metrics of high cardinality the latency monitoring metrics are disabled by default.
# https://prometheus.io/docs/practices/instrumentation/#do-not-overuse-labels
emmitLatencyMetrics: false
metricsAPI:
port: 9090
Note: gRPC latency histograms can generate a high cardinality of metrics, which can lead to performance issues in Prometheus. Therefore, it is optional and disabled by default.
This is an example for enabling metrics collection, including gRPC latency metrics:
telemetry:
enabled: true
collectors:
grpc:
emmitLatencyMetrics: true
When telemetry is enabled, a new metrics port is exposed on agent pods. The port is defined in the metricsAPI.port
field in the configuration.
Collected Metrics
The following metrics are collected by SPIRL components:
- Go Collector: exports metrics about the current Go process using debug.GCStats (base metrics) and runtime/metrics (both in MemStats style and new ones).
- Process Collector: exports the current state of process metrics, including CPU, memory, and file descriptor usage, as well as the process start time.
- gRPC Collector: generates a set of useful metrics about RPCs usage (client and server), such as the number of messages received, RPCs handled, latency distribution, etc.
Note: The Process collector only works on operating systems with a Linux-style proc filesystem and on Microsoft Windows. On other operating systems, it will not collect any metrics.
