By pure good luck I was in work very early so I got moving on a new cert. and having done that, I headed off to my Nagios status page because I was pretty sure that I had a check for this cert. in place. Sure enough, I did, but Nagios wasn't displaying an alert for its expiry, nor had it warned me that it was about to expire.

My bad - I should have mentioned that I had already checked that - I am using the standard check_http plugin. But your asking that has anyway solved the problem, because it jogged my mind somehow. The check_http plugin outputs dates in U.S. format, and this is not configurable. I had a command definition which passed the output of the plugin through, so what Nagios was getting back was the result code from sed and not from the plugin.  

I've now written a little wrapper script which saves the result code and all is now sweetness and light.

It would be nice if check_http's date output format were configurable :-(



Kindest regards,
