Zabbix monitoring Nginx

1. Open the status template in Nginx

[Email protected] ~]# vim/usr/local/nginx-1.8.0/conf/nginx.conf

Location/stat {
Stub_status on;
Access_log off;
Allow the IP address of the machine; #只允许本机访问
Deny all;
}

2. Write a script to monitor Nginx

[Email protected] ~]# vim/home/shell/nc_nginx_check.sh
#!/bin/bash
# Script to fetch nginx statuses for tribily monitoring systems
# Author:dick
# data:2016-05-12
host= the domain name of the website

# Functions to return nginx stats
Function Active {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| grep ' Active ' | awk ' {print $NF} '
}
function reading {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| grep ' Reading ' | awk ' {print $} '
}
function writing {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| grep ' Writing ' | awk ' {print $4} '
}
function waiting {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| grep ' Waiting ' | awk ' {print $6} '
}
function accepts {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| awk nr==3 | awk ' {print '} '
}
function handled {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| awk nr==3 | awk ' {print $} '
}
function requests {
/usr/bin/curl "/http $HOST/stat" 2>/dev/null| awk nr==3 | awk ' {print $} '
}
# Run The requested function
$ #接收第一个参数

[Email protected] ~]# vim/etc/zabbix/zabbix_agentd.conf #添加如下参数

Unsafeuserparameters=1
Userparameter=nginx.accepts,/home/shell/nc_nginx_check.sh accepts
Userparameter=nginx.handled,/home/shell/nc_nginx_check.sh handled
userparameter=nginx.requests,/home/shell/nc_nginx_check.sh Requests
Userparameter=nginx.connections.active,/home/shell/nc_nginx_check.sh Active
userparameter=nginx.connections.reading,/home/shell/nc_nginx_check.sh Reading
userparameter=nginx.connections.writing,/home/shell/nc_nginx_check.sh Writing

[Email protected] ~]#/etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [OK]
Starting Zabbix agent: [OK]
[Email protected] ~]#

3. Test if there is data on the Zabbix server

[email protected] ~]# Yum install zabbix-get-y

[[email protected] ~]# zabbix_get-s The IP address of the monitored end-K "Nginx.accepts"
16187540
[[email protected] ~]# zabbix_get-s The IP address of the monitored end-K "nginx.handled"
16187585
[[email protected] ~]# zabbix_get-s The IP address of the monitored end-K "Nginx.requests"
55652248
[[email protected] ~]# zabbix_get-s The IP address of the monitored end-K "Nginx.connections.active"
349
[Email protected] ~]#
