Some Arvados services publish Prometheus/OpenMetrics-compatible metrics at /metrics. Metrics can help you understand how components perform under load, find performance bottlenecks, and detect and diagnose problems.
To access metrics endpoints, services must be configured with a management token. When accessing a metrics endpoint, prefix the management token with "Bearer " and supply it in the Authorization request header.
curl -sfH "Authorization: Bearer your_management_token_goes_here" "https://0.0.0.0:25107/metrics"
The plain text export format includes “help” messages with a description of each reported metric.
When configuring Prometheus, use a bearer_token or bearer_token_file option to authenticate requests.
scrape_configs:
- job_name: keepstore
bearer_token: your_management_token_goes_here
static_configs:
- targets:
- "keep0.ClusterID.example.com:25107"
