赋予nagios用户执行权限
[root@wgq objects]# chown -R nagios.nagios services_redis.cfg
[root@wgq objects]# chmod 777 services_redis.cfg
添加监控服务项到nagios.cfg
[root@wgq etc]# vim /usr/local/nagios/etc/nagios.cfg
cfg_file=/usr/local/nagios/etc/objects/services_redis.cfg
7，测试redis监控服务
执行命令/usr/lib/nagios/plugins/check_redis.pl -H cache-1 -a 'connected_clients,blocked_clients' -w ~,~ -c ~,~ -m -M 4G -A -R -T 来测试下redis监控是否正常运行
[root@wgq plugins]# /usr/lib/nagios/plugins/check_redis.pl -H 10.2xx.3.x0 -a 'connected_clients,blocked_clients' -w ~,~ -c ~,~ -m -M 4G -A -R -T
