给nagios增加监控当前php进程数的插件,并用pnp出图
脚本说明
脚本默认监控为php-fpm 以TCP方式运行在本机的端口php
php-fpm.conf例
127.0.0.1:9000/value>
其它地址需在脚本中修改相应地址127.0.0.1:9000
最终输出的$total processes为当前正在执行或等待的php数,此数为0或越少越好.

增加执行权限,宫户端nrpe路径为/opt/nagios/
chown nagios:nagios check_phpprocs.sh
chmod 755 check_phpprocs.sh
mv ./check_phpprocs.sh /opt/nagios/libexec/
编辑宫户端nrpe.cfg增加监控命令,这里设置waring阀值为100,critical阀值为200
vi /opt/nagios/etc/nrpe.cfg
- command[check_phpprocs]=/opt/nagios/libexec/check_phpprocs.sh -w 100 -c 200
重启宫户端nrpe
- kill `cat /var/run/nrpe.pid`
- /opt/nagios/bin/nrpe -c /opt/nagios/etc/nrpe.cfg -d
编辑监控端主机文件c1gstudio.cfg,添加监控服务
vi /usr/local/nagios/etc/objects/c1gstudio.cfg
define service{
use local-service,srv-pnp ; Name of service template to use
host_name c1gstudio
service_description PHP Processes
check_command check_nrpe!check_phpprocs
notifications_enabled 1
}
pnp4nagios已配好,srv-pnp为配好的模板 可以直接出图
templates.cfg
- define service {
- name srv-pnp
- register 0
- action_url /pnp/index.php?host=$HOSTNAME$&srv;=$SERVICEDESC$
- process_perf_data 1
