Functionality

The IPsec exporter is determining the state of the configured IPsec tunnels via the following procedure.

1. Starting up the ipsec.conf is read. All tunnels configured via the conn keyword are observed.
2. If the /metrics endpoint is queried, the exporter calls ipsec status <tunnel name> for each configured connection. The output is parsed.
   • If the output contains ESTABLISHED, we assume that only the connection is up.
   • If the output contains INSTALLED, we assume that the tunnel is up and running.
   • If the output contains no match, we assume that the connection is down.
