Hey guys,
I'm trying use check_memcached.pl to monitor a couple of memcached services running on two ports.
I have my command definition setup like this:
# 'check_memcached' command definition
define command {
command_name check_memcached
command_line $USER1$/check_memcached.pl -H $HOSTADDRESS$ -p $ARG1$
}
And I have my service definitions setup like this:
# Define a service to check memcached on web1 (just the basics for right now).
define service{
use local-service ; Name ofservice template to use
host_name web1 service_description Check Memcached 11211 contact_groups linux-admins check_command check_memcached!web1.example.com!11211
notifications_enabled 1 }# Define a service to check memcached on web1 (just the basics for right now).
define service{
use local-service ; Name ofservice template to use
host_name web1 service_description Check Memcached 11212 contact_groups linux-admins check_command check_memcached!web1.example.com!11212
notifications_enabled 1 }And if I run both checks manually they succeed:
[root@monitor1:/usr/local/nagios/etc/objects/servers] #../../../libexec/ check_memcached.pl -H web1.example.com -p 11211
MEMCACHE OK: memcached 1.4.22 on web1.example.com:11211, up 22 minutes 52 seconds
[root@monitor1:/usr/local/nagios/etc/objects/servers] #../../../libexec/ check_memcached.pl -H web1.example.com -p 11212
MEMCACHE OK: memcached 1.4.22 on web1.example.com:11212, up 12 minutes 2 seconds
Yet, in my nagios web interface, I'm getting this error:
Check Memcached 11211CRITICAL05-24-2015 14:28:31
0d 0h 10m 19s
4/4
CRITICAL ERROR - Can not connect to '162.243.60.6' on port 0
Check Memcached 11212CRITICAL05-24-2015 14:29:12
0d 0h 11m 8s
4/4
CRITICAL ERROR - Can not connect to '162.243.60.6' on port 0
I thought I could specify the command in the service definition like this:
check_memcached!web1.example.com!11211
To reproduced the command as it's executed on the command line. How can I specify the port correctly here?
Thanks,
Tim
Hi Tim,
Your command specification is wrong. It will get the -H attribute from the host_name you should not specify it on the check_command and By doing so what you have effectively done is write: check_memcached.pl -H web1.example.com -p web1.example.com 11211 if you enable debug_level=2048 you should be able to see the commands that Nagios is creating.
