Use CHECK_TCP to monitor memcached and Redis instances

In the intranet Environment monitoring external network ECS in the Intranet service port, tried several methods are unsuccessful, and finally consider using CHECK_TCP to monitor, output command information, monitoring results very detailed, great! Share to everyone, hope to help you.

First, check_tcp monitoring memcached

By entering stats to get the parameters, enter quit to quit
So you can use CHECK_TCP to get memcached response time, uptime and other information, the specific command format is as follows:

/usr/local/nagios/libexec/check_tcp-h 192.168.2.11-p 11211-t 5-e-S ' stats\r\nquit\r\n '-e ' uptime '-M crit

The following is the output of the command: Oh, enough detail. It is more important to have the appropriate time, and you can also telnet or tcrmgr inform (Remote Administration tool,tcrmgr inform-port 11209-st 192.168.2.9) results are filtered to get the desired parameters set their own thresholds for more detailed monitoring

Add to Nrpe.cfg inside

Command[check_memcached_11211]=/usr/local/nagios/libexec/check_tcp-h 192.168.2.11-p 11211-t 5-e-S ' stats\r\nquit\r \ n '-e ' uptime '-M crit

Second, check_tcp monitoring Redis

Redis does not support stats need to change to Info command format as above

/usr/local/nagios/libexec/check_tcp-h 192.168.2.11-p 6379-t 5-e-S ' info\r\nquit\r\n ' -e ' Uptim E ' -M crit
