Suddenl y getting below error CRITICAL - Socket timeout afte

[imran_khan]

Hello,

Suddenly getting below error. Sometimes I am getting response from the server.

[root@example.com plugins]# ./check_smtp xyz.com
CRITICAL - Socket timeout after 10 seconds
[root@ example.com plugins]# ./check_smtp xyz.com
SMTP OK - 8.218 sec. response time|time=8.218449s;;;0.000000
[root@ example.com plugins]# ./check_smtp xyz.com
SMTP OK - 6.496 sec. response time|time=6.496059s;;;0.000000
[root@ example.com plugins]# ./check_smtp xyz.com
SMTP OK - 6.530 sec. response time|time=6.529657s;;;0.000000
[root@ example.com plugins]# ./check_smtp xyz.com
CRITICAL - Socket timeout after 10 seconds

I am trying to run above command from Nagios server to smtp sever xyz.com.

Thanks,
Imran Khan.

Either you have packet loss issues, or the timeout is occasionally, not enough. Try increasing the timeout first:

Code: Select all

./check_smtp xyz.com -t 20

From: http://nagiosplugins.org/man/check_smtp

-t, --timeout=INTEGER
Seconds before connection times out (default: 10)

Well in all of the checks you have that passed, you are pushing above 60% of the default check time. It likely would help to bump that up a bit with the timeout flag. Try something like this:

./check_smtp -H xyz.com -t 30 -w 10 -c 20

This will set an overall timeout of 30 seconds, with warning at 10 and critical at 20.
