编写脚本实现Zabbix监控Nginx状态

bobpxp

　　1-配置nginx

[root@linux-node2 extra]# cat ../nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"';
    include extra/www.conf;
    include extra/bbs.conf;
    include extra/blog.conf;
    include extra/status.conf;
}
[root@linux-node2 extra]# cat status.conf
server {
        listen       80;
        server_name  status.etiantian.org;
        location / {
            stub_status on;
            access_log  off;
        }
    }
[root@linux-node2 extra]# ../../sbin/nginx -t            #→检查配置文件语法
[root@linux-node2 extra]# ../../sbin/nginx -s reload     #→重新加载nginx配置生效　　2-编写脚本

[root@linux-node2 extra]# cat /server/scripts/nginx_status.sh
#!/bin/bash
. /etc/init.d/functions
. /etc/profile
# Script to fetch nginx statuses for tribily monitoring systems

# Version 1.0
# Set Variables
BKUP_DATE=`/bin/date +%Y%m%d`
LOG="/data/log/zabbix/webstatus.log"
HOST="status.etiantian.org"
PORT="80"
# Functions to return nginx stats
function active {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
        /usr/bin/curl -s "http://$HOST:$PORT" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
# Run the requested function
$1　　3-配置zabbix-agent

[root@linux-node2 extra]# cat -n /etc/zabbix/zabbix_agentd.conf  
### Option: UserParameter
#       User-defined parameter to monitor. There can be several user-defined parameters.
#       Format: UserParameter=,
#       See 'zabbix_agentd' directory for examples.
#
# Mandatory: no
# Default:
UserParameter=nginx.active,/bin/sh /server/scripts/nginx_status.sh active
UserParameter=nginx.accepts,/bin/sh /server/scripts/nginx_status.sh accepts
UserParameter=nginx.handled,/bin/sh /server/scripts/nginx_status.sh handled
UserParameter=nginx.requests,/bin/sh /server/scripts/nginx_status.sh requests
UserParameter=nginx.reading,/bin/sh /server/scripts/nginx_status.sh reading
UserParameter=nginx.writing,/bin/sh /server/scripts/nginx_status.sh writing
UserParameter=nginx.waiting,/bin/sh /server/scripts/nginx_status.sh waiting
[root@linux-node2 extra]# /etc/init.d/zabbix-agent restart  #→重启zabbix-agent　　4-配置zabbix-server

[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.active"
1
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.accepts"
354
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.handled"      
357
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.requests"
402
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.reading"
0
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.writing"
1
[root@linux-node1 scripts]# zabbix_get -s 10.0.0.8 -p 10050 -k "nginx.waiting"
