服务监控

实例一、监控PHP服务

环境：centos7.6 php7.2 nginx1.12
服务器：test14

• 修改php-fpm和nginx的配置文件，以便查看php的汇总信息和详细信息，如下：

1\ 修改php-fpm配置文件

vim /etc/php-fpm.d/www.conf
把
;pm.status_path = /status
更改为：
pm.status_path = /phpstatus          #去掉了前面的;注释符，并更名为phpstatus（这个可自定义的）

2\ 修改nginx配置文件

server {
        listen       80 default_server;
        server_name  _;
        index index.php index.html
        root         /usr/share/nginx/html;
        location / {
        try_files $uri $uri/ /index.php?$args;
        }
        location ~ \.php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
        }
        location = /phpstatus {
            allow 127.0.0.1;
            #deny all;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
            include fastcgi_params;
            fastcgi_pass 127.0.0.1:9000;
        }
｝

• 重启php-fpm和nginx

nginx -s reload
systemctl restart php-fpm

• 统计一下php的汇总信息

[root@test14 ~]# curl 127.0.0.1/phpstatus
pool:                 www
process manager:      dynamic
start time:           22/Aug/2019:10:36:50 +0800
start since:          793
accepted conn:        3
listen queue:         0
max listen queue:     0
listen queue len:     128
idle processes:       4
active processes:     1
total processes:      5
max active processes: 1
max children reached: 0
slow requests:        0

• zabbix客户端添加php监控项

[root@test14 ~]# cat /etc/zabbix/zabbix_agentd.d/userparameter_php_fpm.conf
# PHP-FPM STATUS
UserParameter=php_fpm.status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/scripts/check_php_fpm.sh '$1'

• zabbix客户端添加监控脚本

[root@test14 ~]# cat /etc/zabbix/zabbix_agentd.d/scripts/check_php_fpm.sh
#!/bin/bash - 
cache_file="/tmp/php_fpm_stats.txt"

if [ -e $cache_file ]; then
    TIMEFLM=`stat -c %Y $cache_file`
    TIMENOW=`date +%s`
    if [ `expr $TIMENOW - $TIMEFLM` -gt 60 ]; then
        rm -f $cache_file
        curl --connect-timeout 1 -m 1 localhost/phpstatus 2> /dev/null > $cache_file
    fi
else
    curl --connect-timeout 1 -m 1 localhost/phpstatus 2> /dev/null > $cache_file
fi

case $1 in
    'pool')
        awk -F '[: ]+' '/pool/{print $NF}' $cache_file
    ;;

    'accepted_conn')
        curl --connect-timeout 1 -m 1 localhost/phpstatus 2> /dev/null | awk -F '[: ]+' '/accepted conn/{print $NF}'
    ;;

    'listen_queue')
        awk -F '[: ]+' '/listen queue/{print $NF}' $cache_file
    ;;

    'max_listen_queue')
        awk -F '[: ]+' '/max listen queue/{print $NF}' $cache_file
    ;;

    'listen_queue_len')
        awk -F '[: ]+' '/listen queue len/{print $NF}' $cache_file
    ;;

    'idle_processes')
        awk -F '[: ]+' '/idle processes/{print $NF}' $cache_file
    ;;

    'active_processes')
        awk -F '[: ]+' '/^active processes/{print $NF}' $cache_file
    ;;

    'total_processes')
        awk -F '[: ]+' '/total processes/{print $NF}' $cache_file
    ;;

    'max_active_processes')
        awk -F '[: ]+' '/^max active processes/{print $NF}' $cache_file
    ;;

    'max_children_reached')
        awk -F '[: ]+' '/max children reached/{print $NF}' $cache_file
    ;;

    *)
        exit 1
    ;;
esac

• 重启zabbix客户端

root@test14 ~]# systemctl restart zabbix-agent

zabbix的web页面上操作：

• 添加模板名为PHP_FPM的模板

• 在模板内添加名为PHP_FPM的应用集

• 按需求添加php的监控项，我这里添加了6个监控项，分别是：
  1、active_processes
  2、idle_processes
  3、total_processes
  4、max_active_processes
  5、accepted_conn
  6、pool
  下面以创建active_processes的监控项为例，其它监控项参考创建：
  

• 添加触发器
  
  及
  

• 添加图形
  
  及
  

注：zabbix监控其它服务可以参照上面的方式上来配置
