cert-status-exporter
A Prometheus exporter that checks the expiry and validity of configured domains once a day.
Usage
To export certificate status metrics, run cert-status-exporter --domain <domain>:<port>:<alpn>[:<name>].
The format means: "Connect to <domain> on port <port> while advertising <alpn> as ALPN during the
TLS negotiations. If <name> is specified, then the metric will be labeled as <name>, instead of <domain>.
<alpn> is a semi-colon separated list of ALPN protocols.
By default, cert-status-exporter will bind to 0.0.0.0:8888 and expose the metrics at 0.0.0.0:8888/metrics. To change
the binding address, you can specify --host and --port to change how cert-status-exporter binds the socket.
Example
cert-status-exporter --host 127.0.0.1 --port 8383 --domain "gnu.org:443:http/1.1;http/1.0;http/0.9": Check the certificate ofgnu.org:443, while presenting the HTTP ALPN protocol names during the TLS negotiation. The metrics are exported with the labelnameequal tognu.org.cert-status-exporter --domain "example.org:5223:xmpp-client:xmpp": Check the certificate ofexample.org:5223, while presentingxmpp-clientas the ALPN protocol during the TLS negotiation. Moreover, export the certificate state with the labelnameequal toxmpp.
