Monitor SSL Certificate Expiration
[Also see our FAQ entry on SSL Certificate Monitoring here.]
An outage caused by an expired SSL certificate is the last thing your DevOps team want their inboxes filled with.
Although, happily, the odds are pretty good that they’ll already be awake when it happens, given that certificates are generally issued with an expiration time identical to the moment the certificate was signed. We presume they weren’t purchasing SSL Certs in their sleep.
Still – much better to ensure that the right people are alerted before expiration. And now Wormly can help you with this small, but critical, task.
You will find a new parameter available in our HTTP Sensor – simply specify the minimum number of days validity that a certificate must possess. Alerts will be generated if that threshold is exceeded.
Note that all certificates presented by your server (i.e. the complete certificate chain) will have their expiration dates checked. So a soon-to-expire intermediary certificate won’t go unnoticed, either.
