Suppress Connection Errors

[berndschneider5]

Is there an option, that the check will not produce a Critical message, if the host/port is not available? Or maybe an Unknown state instead of critical in this case?

You can use the --ignore-connection-problems command line option to return an OK state.

Optionally, you can specify the desired return value.

Examples:

$ ./check_ssl_cert --host github.com --port 111 --ignore-connection-problems
SSL_CERT OK: Cannot connect to github.com:111
$ ./check_ssl_cert --host github.com --port 111 --ignore-connection-problems 1
SSL_CERT WARNING: Cannot connect to github.com:111

ok, sorry. i have not seen this in the documentation. maybe i need new glasses :-)

[matteocorti]

No problem. I didn't remember it and was already adding a new option. Only then I noticed that it was already there.

[berndschneider5]

now i remember... i already used this option, but there was a problem. if i set this, i get randomly a critical error: "Service check timed out after 60.01 seconds"
as soon as i remove this option, the check works again.
Any ideas?

Strange, can you please post the debugging output? (--debug)

[matteocorti]

Analysed the debugging output: the problem most likely lies in the usage of curl to check the connection. I committed a new version (3278d75) which uses netcat. Can you please test?
