Configure check_redis.pl

[alajangi]

Hi Experts,

I want to monitor redis on remote system, when I run the command mentioned below in nagios server it works fine, but I have no luck in configuring nagios configuration files to see in nagios web ui, the result its showing is as shown below, please help me how to configure.

When I run # /usr/local/nagios/libexec/WL-NagiosPlugins/check_redis.pl -H x.x.x.x -p xxxx from command line, the result is
OK: REDIS 2.8.6 on x.x.x.x:xxxx has 2 databases (db0,db15) with 1094 keys, up 16 days 17 hours

But when I configured in nagios configuration files to monitor the result is

Current Status:
UNKNOWN
(for 0d 14h 59m 12s)
Status Information: Total memory value $ can not be interpreted

My configuration files looks

# vi /usr/local/nagios/etc/objects/localhost.cfg

define host{
use linux-server ; Name of host template to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.
host_name localhost
alias localhost

}

define service{

It looks like your custom macro is not getting populated. Where do you set: $_HOSTSYSTEM_MEMORY$ ?
I don't see the macro declared on any of your objects. . .

Excellent Abris, the problem is solved when I Set _SYSTEM_MEMORY '8G'
in vi /usr/local/nagios/etc/objects/localhost.cfg

define host{
use linux-server ; Name of host template to use
; This host definition will inherit all variables that are defined
; in (or inherited by) the linux-server host template definition.
host_name localhost
alias localhost
address 127.0.0.1
_SYSTEM_MEMORY '8G'
}
Thanks,
Kishore.
