The Collector exposes HTTP endpoints at the
to return information about the Collector that can help with debugging issues. The
Collector enables these endpoints by default. To disable these endpoints, set
false in the Collector manifest.
You can access the debug endpoints through your browser.
All endpoints except
/set_log_level are clickable links on the
/debug HTML page,
and are also directly accessible with a
In the Collector manifest, enable Prometheus discovery and configure at least one scrape configuration:
You must complete this step to access the debug endpoints, regardless of whether you're using the Collector to scrape Prometheus endpoints for metrics.
prometheus: enabled: true scrape_configs: - job_name: 'access_debug' scrape_interval: 30s scrape_timeout: 15s static_configs: - targets: ['192.168.192:9100']
If you're running the Collector with Kubernetes, enable port forwarding:
kubectl port-forward chronocollector-POD_NAME LISTEN_PORT
POD_NAME: The name of the Kubernetes pod where your Collector instance is running.
LISTEN_PORT: The port where you can access the Collector. The
listenAddressdefines this port. Default:
Open your browser and navigate to the URL where your Collector is running. The URL is syntax is
/debug. For example, if you're running the Collector locally, navigate to
Click one of the available endpoints from the list.
Displays an HTML page of all debug endpoints, each of which is accessible by clicking an endpoint from the list. This page also displays a list of active scrape targets, including the instance name, job name, and scrape statistics. The table includes three preview links:
- Raw exposition: Includes the actual output of the target's scrape endpoint.
- Dropped series labels: Lists any dropped labels based on relabel rules.
- Ingest series labels: Displays the final set of time series after processing relabel rules.

Returns a JSON list of all Kubernetes Services the Collector detects.
Returns a JSON list of key/value pairs that represent all Kubernetes targets the Collector monitors. The first element is the Collector configuration, followed by a list of all scrape configurations created from the configuration. The endpoint doesn't display Graphite targets.
Returns a JSON representation of the Collector version information. This is the same information the Collector displays at startup.
