Expiring certificate Monitor

Hi all,

 

I'm looking into monitoring expiring certificates on Servers.

 

I'm set up an alarm that gives me the expiration date and time, but need a little help on getting this value into LUA and comparing it to todays date, then, if less than 14 days - alert.

 

Here's my command to look up the expiration date:

 

echo | openssl s_client -connect dashboards.mds-ms.net:443 2>/dev/null | openssl x509 -noout -dates

 

The output of this command is generating an information alarm that states:

 

notAfter=Sep 19 13:38:11 2015 GMT

 

Thanks in advance!
