Nagios TLS Certificate Monitoring
- SoCS has many servers with TLS certificates to encrypt network connections.
- On occasion during the annual renewal process, one of these servers would be missed, which would lead to expired certificate errors when connecting
- SoCS uses Nagios to monitor the health of all servers we manage. A new check using the check_ssl_cert plugin was set up and configured to warn when a certificate is 60 days from expiring, and display a critical alert at 30 days.
- This new check was applied to any servers which use a TLS certificate to ensure we are warned about any that may be missed during the renewal process.
