zabbix密钥监控mysal、nginx、php

一、zabbix监控mysql
在客户机上配置：
[root@iZ25j76vlxnZ ~]# vim /usr/local/zabbix/etc/chk_mysql.sh

#!/bin/bash# -------------------------------------------------------------------------------# FileName:    check_mysql.sh# Revision:    1.0# Date:        2016/06/20# Author:      Liuguangshun# Email:       [e-mail]# Website:     liuguangshun.github.io# Description: # Notes:       ~# -------------------------------------------------------------------------------# Copyright:   2016 (c) Liuguangshun# License:     # 用户名MYSQL_USER='root'# 密码MYSQL_PWD='YyIrpFNhIofsd'# 主机地址/IPMYSQL_HOST='127.0.0.1'# 端口MYSQL_PORT='3306'# 数据连接MYSQL_CONN="/usr/local/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"# 参数是否正确if [ $# -ne "1" ];then    echo "arg error!" fi# 获取数据case $1 in    Uptime)        result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"`        echo $result         ;;    Com_update)        result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3`        echo $result         ;;    Slow_queries)        result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"`        echo $result         ;;    Com_select)        result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3`        echo $result               ;;    Com_rollback)        result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3`                echo $result                 ;;    Questions)        result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"`                echo $result                 ;;    Com_insert)        result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3`                echo $result                 ;;    Com_delete)        result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3`                echo $result                 ;;    Com_commit)        result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3`                echo $result                 ;;    Bytes_sent)        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3`                echo $result                 ;;Bytes_received)        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3`                echo $result                 ;;    Com_begin)        result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3`                echo $result                 ;;        *)        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)"         ;;Esac

[root@iZ25j76vlxnZ ~]# vim /usr/local/zabbix/etc/zabbix_agentd.conf
在后面添加：

# 获取mysql版本UserParameter=mysql.version,mysql -V #  获取mysql性能指标,这个是上面定义好的脚本UserParameter=mysql.status[*],/usr/local/zabbix/etc/chk_mysql.sh $1 #  获取mysql运行状态UserParameter=mysql.ping,mysqladmin -uroot -pYyIrpFNhIofsd -P3306 -h127.0.0.1  ping | grep -c alive

服务端取值：
[root@iZ25t2tlsnqZ ~]# zabbix_get -s 10.44.37.221 -p10050 -k mysql.status[Com_update]
297

二、监控php-fpm
[root@iZ25j76vlxnZ ~]# vim /usr/local/php/etc/php-fpm.conf

pm.status_path = /status    //把；好去掉，启用监控fpm状态

[root@iZ25j76vlxnZ ~]# vim /usr/local/nginx/conf/nginx.conf

 location ~ ^/(status|ping)$         {        fastcgi_pass   127.0.0.1:9000;        include fastcgi_params;        fastcgi_index index.php;        fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;        allow 127.0.0.1;        allow 10.170.236.125;        deny all;        }

[root@iZ25j76vlxnZ ~]# service nginx restart
[root@iZ25j76vlxnZ etc]# curl -s http://localhost/status  //测试是否可以看到php-fpm的状态，有信息即可
创建监控脚本：
[root@iZ25j76vlxnZ ~]# vim /usr/local/zabbix/etc/chk_php-fpm.sh

#!/bin/bash#monitor php-fpm status from zabbix#lincense:GPL#mail:[e-mail]#date:2016.06.20source /etc/bashrc >/dev/null 2>&1source /etc/profile >/dev/null 2>&1LOG=/usr/local/zabbix/etc/phpfpm_status.logcurl -s http://localhost/status >$LOGpool(){ awk '/pool/ {print $NF}' $LOG}process_manager(){ awk '/process manager/ {print $NF}' $LOG}start_since(){ awk '/start since:/ {print $NF}' $LOG}accepted_conn(){        awk '/accepted conn:/ {print $NF}' $LOG}listen_queue(){        awk '/^(listen queue:)/ {print $NF}' $LOG}max_listen_queue(){        awk '/max listen queue:/ {print $NF}' $LOG}listen_queue_len(){        awk '/listen queue len:/ {print $NF}' $LOG}idle_processes(){        awk '/idle processes:/ {print $NF}' $LOG}active_processes(){        awk '/^(active processes:)/ {print $NF}' $LOG}total_processes(){        awk '/total processes:/ {print $NF}' $LOG}max_active_processes(){        awk '/max active processes:/ {print $NF}' $LOG}max_children_reached(){        awk '/max children reached:/ {print $NF}' $LOG}slow_requests(){        awk '/slow requests:/ {print $NF}' $LOG}case "$1" inpool) pool ;;process_manager) process_manager ;;start_since) start_since ;;accepted_conn) accepted_conn ;;listen_queue) listen_queue ;;max_listen_queue) max_listen_queue ;;listen_queue_len) listen_queue_len ;;idle_processes) idle_processes ;;active_processes) active_processes ;;total_processes) total_processes ;;max_active_processes) max_active_processes ;;max_children_reached) max_children_reached ;;slow_requests) slow_requests ;;*)echo "Usage: $0 {pool|process_manager|start_since|accepted_conn|listen_queue|max_listen_queue|listen_queue_len|idle_processes|active_processes|total_processes|max_active_processes|max_children_reached|slow_requests}"esac

引用脚本文件
[root@iZ25j76vlxnZ ~]# vim /usr/local/zabbix/etc/zabbix_agentd.conf

#UserParameter=php-fpm[*],/usr/local/zabbix/etc/chk_php-fpm.sh "$1"UserParameter=phpfpm.status.pool,/usr/local/zabbix/etc/chk_php-fpm.sh poolUserParameter=phpfpm.status.process.manager,/usr/local/zabbix/etc/chk_php-fpm.sh process_managerUserParameter=phpfpm.status.start.since,/usr/local/zabbix/etc/chk_php-fpm.sh start_sinceUserParameter=phpfpm.status.accepted.conn,/usr/local/zabbix/etc/chk_php-fpm.sh accepted_connUserParameter=phpfpm.status.listen.queue,/usr/local/zabbix/etc/chk_php-fpm.sh listen_queueUserParameter=phpfpm.status.max.listen.queue,/usr/local/zabbix/etc/chk_php-fpm.sh max_listen_queueUserParameter=phpfpm.status.listen.queue.len,/usr/local/zabbix/etc/chk_php-fpm.sh listen_queue_lenUserParameter=phpfpm.status.idle.processes,/usr/local/zabbix/etc/chk_php-fpm.sh idle_processesUserParameter=phpfpm.status.active.processes,/usr/local/zabbix/etc/chk_php-fpm.sh active_processesUserParameter=phpfpm.status.total.processes,/usr/local/zabbix/etc/chk_php-fpm.sh total_processesUserParameter=phpfpm.status.max.active.processes,/usr/local/zabbix/etc/chk_php-fpm.sh max_active_processesUserParameter=phpfpm.status.max.children.reached,/usr/local/zabbix/etc/chk_php-fpm.sh max_children_reachedUserParameter=phpfpm.status.slow.requests,/usr/local/zabbix/etc/chk_php-fpm.sh slow_requests

[root@iZ25j76vlxnZ ~]# /etc/init.d/zabbix_agentd restart
[root@iZ25wrxqp21Z etc]# curl http://127.0.0.1/status
pool:                 www
process manager:      dynamic
start time:           27/Apr/2016:14:21:33 +0800
start since:          85601
accepted conn:        37078
listen queue:         0
max listen queue:     13
listen queue len:     128
idle processes:       2
active processes:     1
total processes:      3
max active processes: 5
max children reached: 4
slow requests:        0
下面介绍每个参数的作用：
pool：php-fpm池的名称，一般都是应该是www
process manage：进程的管理方法，php-fpm支持三种管理方法，分别是static,dynamic和ondemand，一般情况下都是dynamic
start time：php-fpm启动时候的时间，不管是restart或者reload都会更新这里的时间
start since：php-fpm自启动起来经过的时间，默认为秒
accepted conn：当前接收的连接数
listen queue：在队列中等待连接的请求个数，如果这个数字为非0，那么最好增加进程的fpm个数
max listen queue：从fpm启动以来，在队列中等待连接请求的最大值
listen queue len：等待连接的套接字队列大小
idle processes：空闲的进程个数
active processes：活动的进程个数
total processes：总共的进程个数
max active processes：从fpm启动以来，活动进程的最大个数，如果这个值小于当前的max_children，可以调小此值
max children reached：当pm尝试启动更多的进程，却因为max_children的限制，没有启动更多进程的次数。如果这个值非0，那么可以适当增加fpm的进程数
slow requests：慢请求的次数，一般如果这个值未非0，那么可能会有慢的php进程，一般一个不好的mysql查询是最大的祸首。

服务器验证：
[root@iZ25t2tlsnqZ ~]# zabbix_get -s 10.44.37.221 -p 10050 -k phpfpm.status.idle.processes
127        //获取到数据说明配置没问题了，接下来在web页面上添加模板


三、监控nginx
[root@iZ25j76vlxnZ ~]# vim /usr/local/nginx/conf/nginx.conf
在php-pfm下增加：

   location /nginx-status {        stub_status on;        access_log on;        allow 127.0.0.1;        allow 10.170.236.125;        deny all;        }

[root@iZ25j76vlxnZ ~]# vim /usr/local/zabbix/etc/chk_nginx.sh

#!/bin/bash# Script to fetch nginx statuses for tribily monitoring systems# Author: [e-mail]# License: GPLv2# Set VariablesBKUP_DATE=`/bin/date +%Y%m%d`LOG="/data/log/zabbix/webstatus.log"HOST=127.0.0.1PORT="80"# Functions to return nginx statsfunction active {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Active' | awk '{print $NF}'}function reading {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Reading' | awk '{print $2}'}function writing {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Writing' | awk '{print $4}'}function waiting {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| grep 'Waiting' | awk '{print $6}'}function accepts {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $1}'}function handled {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $2}'}function requests {/usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null| awk NR==3 | awk '{print $3}'}# Run the requested function$1

在被监控端配置：
[liuguangshun@iZ25j76vlxnZ ~]$ vim /usr/local/zabbix/etc/zabbix_agentd.conf
在最后添加：

UserParameter=nginx.accepts,/usr/local/zabbix/etc/chk_nginx.sh acceptsUserParameter=nginx.handled,/usr/local/zabbix/etc/chk_nginx.sh handledUserParameter=nginx.requests,/usr/local/zabbix/etc/chk_nginx.sh requestsUserParameter=nginx.connections.active,/usr/local/zabbix/etc/chk_nginx.sh activeUserParameter=nginx.connections.reading,/usr/local/zabbix/etc/chk_nginx.sh readingUserParameter=nginx.connections.writing,/usr/local/zabbix/etc/chk_nginx.sh writingUserParameter=nginx.connections.waiting,/usr/local/zabbix/etc/chk_nginx.sh waiting

在被监控查看nginx状态：
[root@iZ25wrxqp21Z etc]# curl http://127.0.0.1/nginx-status
Active connections: 1 
server accepts handled requests
 67561 67561 159860 
Reading: 0 Writing: 1 Waiting: 0
Activeconnections:对后端发起的活动连接数；
server accepts 67561：nginx 总共处理了67561个连接；
handled：成功创建了67561次握手；
requests：总共处理了159860请求。
Reading：nginx读取客户端的header数；
Writing: nginx 返回给客户端的header数；
Waiting: nginx 请求处理完成，正在等待下一请求指令的连接。


服务器上测试
[root@iZ25t2tlsnqZ ~]# zabbix_get -s 10.44.37.221 -p 10050 -k "nginx.accepts"
3151
注意：在web添加模板时，键值（密钥，web是通过键值来链接监控服务器的）要和监控端UserParameter后面的值一样，例如nginx.accepts
