Zabbix监控平台(三)生产环境案例

一,Zabbix生产环境监测案例概述

 

1.1 项目规划

  • 主机分组

    • 交换机
    • Nginx
    • Tomcat
    • MySQL
    • Apache
    • PHP-fpm
    • redis(也有状态页,自己研究)
    • memcache(也有状态页,自己研究)
  • 监控对象识别:

    • 使用SNMP监控交换(监控交换机或路由器)
    • 使用IPMI监控服务器硬件
    • 使用Agent监控服务器(监控操作系统和软件服务)
    • 使用JMX监控JAVA(监控tomcat等java服务)
    • 监控MySQL
    • 监控Web状态
    • 监控Nginx状态
    • 监控Apache状态
    • 监控Tomcat状态
 

1.2 SNMP监控流程(监控交换机或路由器)

  1. 交换机上开启snmp
  2. 在zabbix上添加监控(设置SNMP interfaces)
  3. 关联监控模版
 

1.3 IPMI(监控服务器硬件)

建议使用自定义item监控服务器硬件,在本地执行ipmitool命令来获取数据(虚拟机上没有远程控制卡,所以无法测试)

可以在本地执行ipmitool命令获取数据(命令需要安装)

 

1.4 JMX(使用Zabbix Java Gateway代理)

用来获取java数据,本次的实战内容

 

1.5 实战监控Nginx,Apache,MySQL,PHP-fpm

今天的实战内容,注意总结过程

 

1.6 Zabbix的Web监测

二,Zabbix监控MySQL数据库操作实战

我们需要部署一个MySQL服务和一个zabbix-agentd客户端

 

2.1 编写监控mysql脚本

在nginx服务器(192.168.200.69)上安装一个MySQL 
下面是监控mysql状态的一个shell脚本,内容如下:

mkdir -p /server/scripts

cd /server/scripts

vim check_mysql.sh

cat check_mysql.sh

 
  1. #!/bin/bash
  2. # author:Mr.sun
  3. MySQL_USER="root"
  4. MySQL_PWD="linyaonie"
  5. MySQL_HOST="127.0.0.1"
  6. MySQL_PORT="3306"
  7. MySQL_CONN="/usr/local/mysql/bin/mysqladmin -u${MySQL_USER} -h${MySQL_HOST} -P${MySQL_PORT} -p${MySQL_PWD}"
  8. if [ $# -ne "1" ];then
  9. echo "arg error!"
  10. fi
  11. case $1 in
  12. Uptime)
  13. result=`${MySQL_CONN} status | cut -f2 -d":" | cut -f1 -d "T"`
  14. echo $result
  15. ;;
  16. Com_update)
  17. result=`${MySQL_CONN} extended-status | grep -w "Com_update" | cut -d"|" -f3`
  18. echo $result
  19. ;;
  20. Slow_querles)
  21. result=`${MySQL_CONN} status | cut -f5 -d":" | cut -f1 -d"O"`
  22. echo $result
  23. ;;
  24. Com_select)
  25. result=`${MySQL_CONN} extended-status | grep -w "Com_select" | cut -d "|" -f3`
  26. echo $result
  27. ;;
  28. Com_rollback)
  29. result=`${MySQL_CONN} extended-status | grep -w "Com_rollback" | cut -d"|" -f3`
  30. echo $result
  31. ;;
  32. Questions)
  33. result=`${MySQL_CONN} status | cut -f4 -d":" | cut -f1 -d"S"`
  34. echo $result
  35. ;;
  36. Com_insert)
  37. result=`${MySQL_CONN} extended-status | grep -w "Com_insert" | cut -d"|" -f3`
  38. echo $result
  39. ;;
  40. Com_delete)
  41. result=`${MySQL_CONN} extended-status | grep -w "Com_delete" | cut -d"|" -f3`
  42. echo $result
  43. ;;
  44. Com_commit)
  45. result=`${MySQL_CONN} extended-status | grep -w "Com_commit" | cut -d"|" -f3`
  46. echo $result
  47. ;;
  48. Bytes_sent)
  49. result=`${MySQL_CONN} extended-status | grep -w "Bytes_sent" | cut -d"|" -f3`
  50. echo $result
  51. ;;
  52. Bytes_received)
  53. result=`${MySQL_CONN} extended-status | grep -w "Bytes_received" | cut -d"|" -f3`
  54. echo $result
  55. ;;
  56. Com_begin)
  57. result=`${MySQL_CONN} extended-status | grep -w "Com_begin" | cut -d"|" -f3`
  58. echo $result
  59. ;;
  60. *)
  61. echo "Usage:$0(Uptime|Com_update|Slow_querles|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)"
  62. ;;
  63. esac

2.2在zabbix-agent端创建自定义键值配置文件

 

创建mysql.status的键值

chmod +x check_mysql.sh

chown zabbix.zabbix check_mysql.sh

cd /etc/zabbix/zabbix_agentd.d/

vim mysql_status.conf

cat mysql_status.conf

 
  1. UserParameter=mysql.status[*],/server/scripts/check_mysql.sh $1

image_1cudrpo93poikoe1pmck7fo1hm.png-40.3kB

 

删除旧键值模版

rm -rf userparameter_mysql.conf

image_1cudrvbe5c8uom31jqcf211onl1g.png-24.2kB

 

创建mysql.ping和mysql.version的键值

vim mysql_status.conf

cat mysql_status.conf

 
  1. UserParameter=mysql.status[*],/server/scripts/check_mysql.sh $1
  2. UserParameter=mysql.ping,/usr/bin/mysqladmin -uroot -plinyaonie ping | grep -c alive
  3. UserParameter=mysql.version,/usr/bin/mysql -V

image_1cudsdqja1ste1cfbfjicff1nuv3h.png-18.8kB


image_1cuds08uo1rvrb7dnes1274gu91t.png-34.9kB

 

重启zabbix-agentd服务

/etc/init.d/zabbix-agent restart

image_1cuds2ep64qkrbmkg51ei3sap2a.png-44.2kB

 

2.3 在zabbix-server端测试键值

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.status[Uptime]"

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.status[Com_commit]"

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.status[Bytes_sent]"

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.status[Bytes_received]"

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.ping"

zabbix_get -s 192.168.200.69 -p 10050 -k "mysql.version"

image_1cudsc22irrdbr719na1gclo2u34.png-59.3kB

 

2.4 在zabbix-server端Web前台引入zabbix监控MySQL的模版

zabbix自带监控MySQL的模版,我们只需要将模版引入到主机即可 
配置-->主机-->选择主机-->模板,然后将MySQL模版连接到此主机即可

image_1cudspn801q6kl24ktkhk6jo96e.png-103.7kB


image_1cudstbnn15g3i341olaer46qk8g.png-90.2kB


image_1cudsudd2td81o3m7c01qm01b8ba6.png-107kB


image_1cudt0afu7o11kmbp1f81g41gbj.png-222.4kB

从图中可以发现模版里的键值都是我们之前已经定义好了的键值

 

三,Zabbix监控Apache、Nginx操作实战

 

为了避免冲突,若系统中已经安装httpd服务,务必删除

rpm -q httpd

/etc/init.d/iptables stop

setenforce 0

image_1cue2ahodb021fos1kh24ct1ea69.png-28.4kB

 

源码构建apache

tar xf httpd-2.2.17.tar.gz -C /usr/src/

cd /usr/src/httpd-2.2.17/

./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi && make && make install

cd /usr/local/httpd/

ls

ln -s /usr/local/httpd/bin/* /usr/local/bin/

cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd

chmod +x /etc/init.d/httpd

cd /usr/local/httpd/htdocs/

echo "`hostname -I` I am apache" > index.html

cat index.html

cd /usr/local/httpd/conf

awk '/#ServerName/{print NR,$0}' httpd.conf

sed -i -e '97 s/#//;s/example/yunjisuan/' httpd.conf

sed -n '97p' httpd.conf

/etc/init.d/httpd start

netstat -antup | grep httpd

echo "`hostname -I` www.yunjisuan.com" >> /etc/hosts

tail -1 /etc/hosts

curl www.yunjisuan.com

image_1cue303an1ih8eh615vi11fqnd746.png-94.9kB

 

3.1.2 开启apache状态页

要打开apache的ServerStatus页面,需要在httpd.conf文件最下边加入代码段

 
  1. ExtendedStatus On
  2. <location /server-status>
  3. SetHandler server-status
  4. Order Deny,Allow
  5. Deny from all
  6. Allow from 127.0.0.1
  7. </location>

最后,重启动apache即可

image_1cue33ms31bgnm9e5d91796dln53.png-49.5kB

 

3.1.3 下载apache zabbix模版并解压

 

从如下地址下载apache zabbix模版(上边有下载链接)

wget https://github.com/lorf/zapache/archive/master.zip

 

解压zip格式压缩文件

unzip master

ls -d zapache-master

cd zapache-master/

ls

此模版文件中包含了监控apache的脚本文件,zabbix的apache模版文件,还有客户端zabbix自定义传key文件。

image_1cue3ec0kl201fg46qj18vgnoh5g.png-88.4kB

首先将zapache放到需要监控的apache服务器上的/etc/zabbix/scripts目录下,如果没有scripts目录,自行创建一个即可。然后执行授权:

cp zapache /etc/zabbix/scripts/

cd /etc/zabbix/scripts/

chmod 755 /etc/zabbix/scripts/zapache

./zapache

 
  1. zapache version: 1.5
  2. usage:
  3. ./zapache [<url>] TotalAccesses - Check total accesses.
  4. ./zapache [<url>] TotalKBytes - Check total KBytes.
  5. ./zapache [<url>] CPULoad - Check CPU load.

  24. ./zapache [<url>] OpenSlotWithNoCurrentProcess - Check Open Slots with No Current Process.

image_1cue3n4cb5sfen27sm1r8k19dl6d.png-135kB

接着将userparameter_zapache.conf.sample文件放到/etc/zabbix/zabbix_agentd.d目录下,并重命名为userparameter_zapache.conf文件,然后修改键值命令的路径。

最后,重启zabbix-agent服务

cd /root/zapache-master/

cp userparameter_zapache.conf.sample /etc/zabbix/zabbix_agentd.d/userparameter_zapache.conf

cd /etc/zabbix/zabbix_agentd.d/

vim userparameter_zapache.conf

tail -1 userparameter_zapache.conf

 
  1. UserParameter=zapache[*],/etc/zabbix/scripts/zapache \$1 #本行要修改

/etc/init.d/zabbix-agent restart

image_1cue41c20r6l3ba8vb1d5braqcb.png-68.7kB

 

3.1.4 测试键值

 

在zabbix-agent端查看脚本用法

cd /etc/zabbix/scripts/

./zapache

 
  1. zapache version: 1.5
  2. usage:
  3. ./zapache [<url>] TotalAccesses - Check total accesses.
  4. ./zapache [<url>] TotalKBytes - Check total KBytes.
  5. ./zapache [<url>] CPULoad - Check CPU load.
  6. ./zapache [<url>] Uptime - Check uptime.
  7. ./zapache [<url>] ReqPerSec - Check requests per second.
  8. ./zapache [<url>] BytesPerSec - Check Bytes per second.
  9. ./zapache [<url>] BytesPerReq - Check Bytes per request.
  10. ./zapache [<url>] BusyWorkers - Check busy workers.
  11. ./zapache [<url>] IdleWorkers - Check idle workers.
  12. ./zapache [<url>] version - Version of this script.
  13. ./zapache [<url>] ping - Check if Apache is up.
  14. ./zapache [<url>] WaitingForConnection - Check Waiting for Connection processess.
  15. ./zapache [<url>] StartingUp - Check Starting Up processess.

  23. ./zapache [<url>] IdleCleanupOfWorker - Check Idle Cleanup of Worker Processess.
  24. ./zapache [<url>] OpenSlotWithNoCurrentProcess - Check Open Slots with No Current Process.

我们发现脚本需要传递两个参数,即url和选项,然后我们在zabbix-server端进行键值测试

zabbix_get -s 192.168.200.78 -p 10050 -k "zapache[127.0.0.1 TotalAccesses]"

zabbix_get -s 192.168.200.78 -p 10050 -k "zapache[www.yunjisuan.com version]"

zabbix_get -s 192.168.200.78 -p 10050 -k "zapache[www.yunjisuan.com ping]"

image_1cue48mae991ha9gt35t9ubco.png-34.4kB

 

3.1.5 在zabbix-server的Web页面上监控apache

 

(1)创建一个监控apache的主机

image_1cue4dod21gth1a6jsjvobiajsdl.png-103.6kB


image_1cue4gu1u9f017cj1sck1dqu1q8el.png-108.7kB

 

(2)导入apache监控项的模版(上边有模板下载链接)

zabbix默认并没有监控apache的监控项模版。我们需要将它导入到apache中。在之前解压出来的目录中,有待导入的web模版

 
  1. [root@apache ~]# tree zapache-master/
  2. zapache-master/
  3. ├── httpd-server-status.conf.sample
  4. ├── README.md
  5. ├── zapache-template-active.xml #Web模版
  6. └── zapache-template.xml #Web模版
  7. 0 directories, 4 files

我们将这两个.xml后缀的拷贝到windows上,然后从Web界面导入进去

image_1csinasjhvo71d3t98l98s191r44.png-23.8kB


image_1csinb0k84lghju1gq81b2jeeg4h.png-44.6kB

导入以后Web端就有监控apache的监控项模版了

 

(3)将模版链接到apache主机

image_1cue5raan1k2u1chkigp1ne4f88fh.png-79.9kB


image_1cue68p7takq11su1j0a13crslskm.png-57.2kB


image_1cue656ao9uf1hiv121j1bjtj9ek9.png-81.4kB

 

3.2 实战监控nginx

 

3.2.1 开启nginx状态页

vim /usr/local/nginx/conf/nginx.conf

/usr/local/nginx/sbin/nginx -t

/usr/local/nginx/sbin/nginx

 
  1. #在nginx的配置文件中,添加status配置
  2. location = /nginx-status {
  3. stub_status on;
  4. access_log off;
  5. allow 127.0.0.1;
  6. allow 192.168.200.78; #zabbix服务器地址一般是内网地址
  7. deny all;
  8. }

image_1cue6rq4u1s6u19r11uivqctsaqo.png-39.1kB

 

3.2.2 访问设置好的nginx-status链接

curl 192.168.200.78/nginx-status

 
  1. nginx status详细说明如下:
  2. Active connections:对后端发起的活动连接数;
  3. acceptsnginx总共处理了多少个连接;
  4. handlednginx成功创建了几次握手;
  5. requestsnginx总共处理了多少请求。
  6. Readingnginx读取客户端的header数;
  7. Writingnginx返回给客户端的header数;
  8. Waitingnginx请求处理完成,正在等待下一请求指令的连接

image_1cue6u4tm3m84501q6gd2vadr5.png-23.6kB

 

3.2.3 编写nginx状态监控脚本

vim nginx_status.sh

cat nginx_status.sh

 
  1. #!/bin/bash
  2. # Set Variables
  3. HOST="127.0.0.1"
  4. PORT="80"
  5. #Functions to return nginx stats
  6. function active(){
  7. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Active" | awk '{print $NF}'
  8. }
  9. function reading(){
  10. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Reading" | awk '{print $2}'
  11. }
  12. function writing(){
  13. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Writing" | awk '{print $4}'
  14. }
  15. function accepts(){
  16. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $1}'
  17. }
  18. function handled(){
  19. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $2}'
  20. }
  21. function requests(){
  22. /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $3}'
  23. }
  24. function ping(){
  25. /sbin/pidof nginx | wc -l
  26. }
  27. # Run the requested function
  28. $1

image_1cue73rp7n8j12o4cu1a9d3cjs2.png-88.4kB

 

3.2.4 给脚本可执行权限并且授权

chmod +x nginx_status.sh

chown zabbix.zabbix nginx_status.sh

image_1cue75afb18kb1rps19nc1id7vddsf.png-30.2kB

 

3.2.5 在zabbix-agent端配置nginx键值配置文件并重启agent客户端

cd /etc/zabbix/zabbix_agentd.d

vim nginx.conf

cat nginx.conf

 
  1. UserParameter=nginx.active,/usr/bin/curl -s "http://127.0.0.1:80/nginx-status" | grep "Active" | awk '{print $NF}'
  2. UserParameter=nginx.status[*],/etc/zabbix/scripts/nginx_status.sh $1

/etc/init.d/zabbix-agent restart

image_1cue7vni41mi71fjfqdv1njl1tuatp.png-46.8kB

 

3.2.6 在zabbix-server端测试键值

zabbix_get -s 192.168.200.78 -k "nginx.status[reading]" -p 10050

zabbix_get -s 192.168.200.78 -k "nginx.status[active]" -p 10050

zabbix_get -s 192.168.200.78 -k "nginx.status[reading]" -p 10050

zabbix_get -s 192.168.200.78 -k "nginx.status[writing]" -p 10050

zabbix_get -s 192.168.200.78 -k "nginx.status[ping]" -p 10050

image_1cue81tcvuno1nrlqk8cv9puqum.png-40.7kB

 

3.2.7 接下来我们需要在Web端导入nginx监控模版(上文有模板下载链接)

image_1csine64afjmacp1hndkq7q9s65.png-36.3kB


image_1cue87i447jenss1hb65kfe113j.png-97.5kB


image_1cue8bk678p8gc1t8qvpgba518f.png-87.5kB


image_1cue8d25b10f012c51nqe1cu61png18s.png-90.3kB


image_1cue8dlvi1tdati6ed9osl1nig199.png-120.6kB

 

3.2.8 异常调试

如果Zabbix图形界面一直没有获取到数据,可以通过在zabbix server上执行zabbix_get手动测试: 
/usr/local/zabbix/bin/zabbix_get -s 192.168.200.78 -p 10050 -k "nginx.status[active]" 
如果获取数据有问题,会给出相应提示,如果能够获取到数据,那就没问题了。

 

四,Zabbix监控Tomcat操作实战

zabbix监控tomcat,需要zabbix_server开启java poller,zabbix_java开启javaGateway,端口10052,Tomcat JMX开启12345端口,提供性能数据。

数据获取流程为:java poller<-->javaGateway:10052<-->Tomcat:12345

image_1csinfi11chr1f4fstgjvd130n7p.png-89.3kB

 

4.1 配置Tomcat JMX(安装Tomcat步骤省略)

 

配置jmx,在需要监控的tomcat服务器上,编辑catalina.sh,加入如下配置

vim /usr/local/tomcat/bin/catalina.sh

sed -n '249p' /usr/local/tomcat/bin/catalina.sh

 
  1. CATALINA_OPTS="-server -Xms256m -Xmx512m -XX:PermSize=64M -XX:MaxPermSize=128m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.200.78 -Dcom.sun.management.jmxremote.port=12345"

这里需要注意,必须增加-Djava.rmi.server.hostname选项,并且后面的IP就是tomcat服务器的IP

image_1cue92lth1101r7i82d38f1fqk1e.png-34.8kB

 

4.2 重启Tomcat

/usr/local/tomcat/bin/shutdown.sh

/usr/local/tomcat/bin/startup.sh

netstat -antup | grep java

image_1cuescd451r651qhcbjpjjb639.png-78kB

 

4.3 编译zabbix,加入java支持(需要先安装JDK)

在zabbix server服务器上,编译安装zabbix-server,需要加上--enable-java,以支持jmx监控,如果之前的zabbix server没加此选项,那么需要重新编译安装,编译参数如下:

 
  1. ./configure --prefix=/usr/local/zabbix --with-mysql --with-net-snmp --with-libcurl --enable-server --enable-agent --enable-proxy --enable-java --with-libxml2
 

特别提示

在启用--enable-java编译zabbix之前,zabbix server服务器上需要安装JDK,并需要设置JAVA_HOME,以让系统能够识别到jdk的路径

 

4.3.1 在zabbix-server端安装JDK

tar xf jdk-8u60-linux-x64.tar.gz -C /usr/local/

ln -s /usr/local/jdk1.8.0_60/ /usr/local/jdk

sed -i.ori '$a export JAVA_HOME=/usr/local/jdk\nexport PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH\nexport CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar' /etc/profile

tail -3 /etc/profile

source /etc/profile

提示:

java gateway服务的配置脚本settings.sh不需要修改任何配置。

 

4.3.3 启动java Gateway服务

/usr/local/zabbix/sbin/zabbix_java/startup.sh

netstat -antup | grep 10052

image_1cuet5r5hjl6p4ie2vjjs1tpn3q.png-69.8kB

 

4.4 修改zabbix server配置

默认的情况下,zabbix server未启用javaPollers,需要修改zabbix_server.conf的如下配置

 

修改以下配置文件的内容

cd /usr/local/zabbix/etc/

cat -n zabbix_server.conf | sed -n '215p;223p;231p'

 
  1. 215 # JavaGateway=
  2. 223 # JavaGatewayPort=10052
  3. 231 # StartJavaPollers=0

image_1cuet8g2k1q5k1f1f1thm2b6tvv47.png-24.1kB

 

将上述配置文件内容修改成如下

vim zabbix_server.conf

cat -n zabbix_server.conf | sed -n '215p;223p;231p'

 
  1. 215 JavaGateway=127.0.0.1 #JavaGateway的地址
  2. 223 JavaGatewayPort=10052
  3. 231 StartJavaPollers=5

image_1cuetc5hjemf1sg0kkr8pe1i3t54.png-23.2kB

 

启动zabbix_server服务并查看已经打开的java poller进程

/etc/init.d/zabbix_server start

ps -ef | grep "java poller" | grep -v grep

五,Zabbix监控PHP-FPM操作实战

php-fpm和nginx一样内建了一个状态页,对于想了解php-fpm的状态以及监控php-fpm非常有帮助

 

5.1 启用php-fpm状态功能

 

修改php-fpm配置文件,确保如下配置是打开状态

pm.status_path = /status,具体操作如下

 

在Zabbix-server端操作如下

cd /usr/local/php/etc

ls

sed -n '360p' php-fpm.conf

vim php-fpm.conf +360

sed -n '360p' php-fpm.conf

image_1cueud3385dp2me1vjt1k8r1i0a8c.png-30.9kB

 

重启php-fpm服务

netstat -antup | grep php-fpm

pkill php-fpm

netstat -antup | grep php-fpm

/usr/local/php/sbin/php-fpm

netstat -antup | grep php-fpm

image_1cueuhob2kej1961c6n1hub1kid8v.png-34.7kB

 

5.2 nginx配置php-fpm状态页面

 

配置php-fpm状态页面

vim /usr/local/nginx/conf/nginx.conf

cat /usr/local/nginx/conf/nginx.conf

 
  1. worker_processes 1;
  2. events {
  3. worker_connections 1024;
  4. }
  5. http {
  6. include mime.types;
  7. default_type application/octet-stream;
  8. sendfile on;
  9. keepalive_timeout 65;
  10. server {
  11. listen 80;
  12. server_name localhost;
  13. location / {
  14. root html;
  15. index index.php index.html index.htm;
  16. }
  17. location = /nginx-status {
  18. stub_status on;
  19. access_log off;
  20. }
  21. location = /status { #添加此location
  22. include fastcgi_params;
  23. fastcgi_pass 127.0.0.1:9000;
  24. fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
  25. }
  26. location ~ \.php$ {
  27. fastcgi_pass 127.0.0.1:9000;
  28. fastcgi_index index.php;
  29. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  30. include fastcgi_params;
  31. }
  32. }
  33. }

image_1cuevftlf9ra93o11j8elo1c0aa6.png-78.4kB

 

重启动nginx服务

/usr/local/nginx/sbin/nginx -t

/usr/local/nginx/sbin/nginx -s reload

image_1cuevh8r9h0bo6g130n1n7hgk6aj.png-22.6kB

 

5.3 状态页浏览器访问测试

php-fpm状态页比较个性化的一个地方是它可以带参数,可以带的参数有json、xml、html,使用zabbix或者nagios监控可以考虑使用xml或者默认方式。

http://192.168.200.69/status

image_1cuevj7dla6jid51jh01b3f1s6kb0.png-25.4kB

 

具体含义说明如下

curl 127.0.0.1/status

 
  1. pool: www #fpm进程池名称,大多数为www
  2. process manager: dynamic #进程管理方式(static,dynamic or nodemand.dynamic)
  3. start time: 12/Dec/2018:07:35:24 +0800 #启动日期
  4. start since: 1137 #运行时长
  5. accepted conn: 142 #当前FPM进程池接受的请求数
  6. listen queue: 0 #请求等待队列,如果值不是0,那么要增加FPM的进程数
  7. max listen queue: 0 #请求等待队列最高的数量
  8. listen queue len: 128 #socket等待队列长度
  9. idle processes: 1 #空闲进程数量
  10. active processes: 1 #活跃进程数量
  11. total processes: 2 #总进程数量
  12. max active processes: 2 #最大的活跃进程数量(FPM启动开始算)
  13. max children reached: 0 #达到最大子进程的次数,如果值不为0,那么需要调高最大进程数
  14. slow requests: 0 #当启用了php-fpm的slow-log功能时,如果出现php-fpm慢请求这个计数器会增加,一般不当的MySQL查询会触发这个值

其他状态参数显示形式的数据(json,xml,html)

 

以xml的格式输出PHP-fpm状态页

curl 127.0.0.1/status?xml

 
  1. <?xml version="1.0" ?>
  2. <status>
  3. <pool>www</pool>
  4. <process-manager>dynamic</process-manager>
  5. <start-time>1516953418</start-time>
  6. <start-since>3731</start-since>
  7. <accepted-conn>647</accepted-conn>
  8. <listen-queue>0</listen-queue>
  9. <max-listen-queue>4</max-listen-queue>
  10. <listen-queue-len>128</listen-queue-len>
  11. <idle-processes>2</idle-processes>
  12. <active-processes>1</active-processes>
  13. <total-processes>3</total-processes>
  14. <max-active-processes>3</max-active-processes>

5.4 在Zabbix agent端修改配置

在创建Zabbix的agent端键值配置文件的时候,我们可以考虑利用PHP-fpm状态页的不同输出格式来抓取数据。例如我们利用xml格式获取数据,操作如下:

 

查看xml格式PHP-fpm状态页数据

curl 127.0.0.1/status?xml

 
  1. <?xml version="1.0" ?>
  2. <status>
  3. <pool>www</pool>
  4. <process-manager>dynamic</process-manager>
  5. <start-time>1516953418</start-time>
  6. <start-since>3731</start-since>
  7. <accepted-conn>647</accepted-conn>
  8. <listen-queue>0</listen-queue>
  9. <max-listen-queue>4</max-listen-queue>
  10. <listen-queue-len>128</listen-queue-len>
  11. <idle-processes>2</idle-processes>
  12. <active-processes>1</active-processes>
  13. <total-processes>3</total-processes>
  14. <max-active-processes>3</max-active-processes>
  15. <max-children-reached>0</max-children-reached>
  16. <slow-requests>0</slow-requests>

image_1cuevuhl01isr1qgs1fjpbj621rdh.png-43.9kB

 

创建zabbix监控的agent端键值配置文件

cd /etc/zabbix/zabbix_agentd.d/

vim userparameter_php-fpm.conf

cat userparameter_php-fpm.conf

 
  1. UserParameter=php-fpm.status[*],/usr/bin/curl -s "http://127.0.0.1/status?xml" | grep "<$1>" | awk -F "[>|<]" '{print $$3}'
  2. 这里需要注意在脚本里如果写成$3的话,脚本会认识是一个变量,因此我们需要用$$3

重启动agent客户端

/etc/init.d/zabbix-agent restart

image_1cuf0b8iksftml01k0rb7m1jnkeb.png-18.2kB

 

5.5 进行键值配置文件测试

zabbix_get -s 192.168.200.69 -p 10050 -k "php-fpm.status[process-manager]"

zabbix_get -s 192.168.200.69 -p 10050 -k "php-fpm.status[start-since]"

zabbix_get -s 192.168.200.69 -p 10050 -k "php-fpm.status[active-processes]"
