PDC agent metrics

The PDC agent exposes Prometheus-compatible metrics for monitoring and alerting. By default, these metrics are available at http://<agent-host>:8090/metrics. You can change the metrics port using the metrics-addr flag. Example: --metrics-addr=":9100"

Available metrics

The metrics include counters, gauges, and native histograms that provide insight into the agent’s behavior, including:

SSH connection count and duration
TCP connection counts
Signing request latency
Restart counts with exit codes

The following metrics are currently supported:

Metric name	Type	Description	Labels
`pdc_agent_signing_requests_duration_seconds`	Native histogram	Duration of signing requests in seconds	`status`
`pdc_agent_ssh_restarts_total`	Counter	Total number of SSH restarts	`exit_code`
`pdc_agent_ssh_open_channels`	Gauge	Number of open SSH channels	none
`pdc_agent_tcp_connections_total`	Counter	Number of opened TCP connections	`target`, `status`
`pdc_agent_ssh_time_to_connect_seconds`	Native histogram	Time spent to establish SSH connection	none
