Installing the Perl Redis Environment

[Email protected] ~]# yum install-y perl-cpan perl-time-hires perl-yaml

[[email protected] ~]# perl-mcpan-e Shell

cpan> Install Redis

After encountering the [Yes] location, all the way to the return, you need to install a lot of components.

I spent more than 2-3 hours, and kept the carriage return, finally installed.

Place the check_redis.pl file in the/usr/local/nagios/libexec/directory

Set permissions

[Email protected] ~]#chmod 755 check_redis.pl

[Email protected] ~]#chown nagios:nagios check_redis.pl

Test Plug-ins

[Email protected] ~]#cd/usr/local/nagios/libexec/

[Email protected] ~]#/check_redis.pl-h 10.168.13.230-p 6379

Ok:redis 2.8.19 on 10.168.13.230:6380 have 1 databases (DB0) with + keys, up 98 days 7 hours

Testing the time to connect to Redis

./check_redis.pl-h 10.168.13.230-p 6379-t 0.5,1

Test CPU

./check_redis.pl-h 10.168.13.230-p 6379-a ' Used_cpu_sys,used_cpu_user,used_cpu_user_children,used_cpu_sys_ Children '-W ~,~,~,~-C ~,~,~,~

Test memory

./check_redis.pl-h 10.168.13.230-p 6379-a ' Used_memory_human,used_memory_peak_human '-w ~,~-C ~,~

Test the number of connections

./check_redis.pl-h 10.168.13.230-p 6379-a ' Connected_clients,blocked_clients,client_longest_output_list,client_ Biggest_input_buf '-W 100,5,~,~-C 500,10,~,~

Started to formally monitor with Nagios.

Edit File

Vi/usr/local/nagios/etc/objects/commands.cfg

The last line adds the following:

# Check Redis

}

# Check Redis

Define Command {

Command_name Check_redis_conn_time

Command_line $USER 1$/check_redis.pl-h $HOSTADDRESS $-P $ARG 1$-T $ARG 2$

}
