在nagios中使用python脚本监控linux主机
在被监控端192.168.5.1101.先把getload.py放到/usr/local/nagios/libexec内
# vim /usr/local/nagios/libexec/getload.py
#! /usr/bin/env python
import os,sys
(d1,d2,d3) = os.getloadavg()
if d1 >= 5.0:
print "GETLOADAVG CRITICAL: Load average is %.2f" % (d1)
sys.exit(2)
elif d1 >= 2.0:
print "GETLOADAVG WARNING: Load average is %.2f" %(d1)
else:
print "GETLOADAVG OK: Load average is %.2f" %(d1)
# chmod a+x getload.py
# chown nagios:nagios getload.py
2. 在nrpe内加入自定义的命令
# vim /usr/local/nagios/etc/nrpe.cfg
command=/usr/local/nagios/libexec/getload.py
------------------------------------------------------------------------------------------
在nagios服务端测试192.168.5.10
# /usr/local/nagios/libexec/check_nrpe -H 192.168.5.110 -c nh_check_getload
GETLOADAVG OK: Load average is 0.06
在服务端测试192.168.5.10的nagios中加入自定义脚本
# cd /usr/local/nagios/etc/objects
# vim hosts_192.168.5.110.cfg
define host{
use linux-server
host_name 192.168.5.110

# service nagios reload
在nagios的services中就可看到的状态了
