check_ssl_cert ssl handshake error

Hello All,

I'm getting ssl handshake errors when using a check_ssl_cert Nagios plugin.

Specifically - 140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177:

I know it's probably a timeout or server is busy issue - but I'd like it not to go in critical state and send alerts.

I've got this defined in my 'define host' : max_check_attempts 5

How can I make it keep trying until it succeeds ? I'm just trying to keep track of the days before the cert expires.

If all else fails - i might just write a text file with cert expiration but rather not do that.

I'm using this plugin:

If anyone can help - it'd be nice.

Chris
