使用nagios監(jiān)控某進(jìn)程的運(yùn)行狀態(tài)

使用nagios監(jiān)控被監(jiān)控服務(wù)器上的某一程序，腳本通過查看進(jìn)程狀態(tài)返回狀態(tài)值，并傳送給nagios，來(lái)達(dá)到監(jiān)控目的。nagios每個(gè)插件監(jiān)控會(huì)返回以下狀態(tài)值，我只用到了 0 、1、 2

復(fù)制代碼代碼如下:

#!/bin/bash -x
# Exit values:
# ------------
#    0  OK
#    1  Warning
#    2  Cirital
#    3  Unknown
#    Others Unknown

##-------
dfs_process=`ps -ef | grep './dfs client' | grep -v grep`
if [ -z "$dfs_process" ];then
        echo "Critical the program of gather is down !!!"
        exit 2
fi

process_ppid=`echo $dfs_process|awk '{print $3}'`
process_pid=`echo $dfs_process|awk '{print $2}'`

if [ $process_ppid = 1 ];then
        echo 'The process of dfs put back'
        exit 1
else
        while [ $process_ppid != 1 ]
                do
                old_process_ppid=$process_ppid
                process_ppid=`ps -ef | grep $process_ppid | grep -v $process_pid | grep -v grep | awk '{print $3}'`
                process_pid=`ps -ef | grep $old_process_ppid| grep -v $process_pid | grep -v grep|awk '{print $2}'`
                done
        dfs_pprocess=`ps -ef | grep "$process_pid     1" | grep -v grep`
        echo "process of './dfs client' OK ! - Parent process is `echo $dfs_pprocess | awk '{print $8,$9,$10}'`"
        exit 0

fi

然后，打開被監(jiān)控端nrpe的配置文件
# vi /usr/local/nagios/etc/nrpe.cfg
添加：
 

復(fù)制代碼代碼如下:

command[check_dfs]=/usr/local/nagios/libexec/check_dfs.sh

最后，在監(jiān)控端定制監(jiān)控服務(wù)(service.cfg)即可開始監(jiān)控服務(wù)了。
