自定义监控CPU负载

Agent端:

[root@zabbix-agent1 ~]# vim /etc/zabbix/zabbix_agentd.conf

UserParameter=cpu_load1,/usr/bin/w|awk 'NR==1 {print $10}'|awk -F, '{print $1}'

UserParameter=cpu_load5,/usr/bin/w|awk 'NR==1 {print $11}'|awk -F, '{print $1}'

UserParameter=cpu_load15,/usr/bin/w|awk 'NR==1 {print $12}'

Server端:

[root@zabbix-server ~]# zabbix_get -s 10.0.0.101 -k cpu_load1

0.00

[root@zabbix-server ~]# zabbix_get -s 10.0.0.101 -k cpu_load5

0.01

[root@zabbix-server ~]# zabbix_get -s 10.0.0.101 -k cpu_load15

0.05

ab压测使CPU有波动

Server端:

[root@zabbix-server ~]# yum install -y httpd-tools

[root@zabbix-server ~]# ab -n 10000 -c 100 http://10.0.0.101/index

Agent端:

[root@zabbix-agent1 ~]# yum install -y httpd

[root@zabbix-agent1 ~]# systemctl start httpd

[root@zabbix-agent1 ~]# vim /var/www/html/index.html

[root@zabbix-agent1 ~]# curl --head http://10.0.0.101/index.html

自定义监控Nginx服务

Agent端:

[root@zabbix-agent1 ~]#  vim /etc/yum.repos.d/nginx.repo

[root@zabbix-agent1 ~]#  cat /etc/yum.repos.d/nginx.repo

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/7/x86_64/

gpgcheck=0

enabled=1

[root@zabbix-agent1 ~]#  rpm -qa | grep centos-release

centos-release-7-4.1708.el7.centos.x86_64

[root@zabbix-agent1 ~]# yum install -y nginx

[root@zabbix-agent1 ~]# systemctl start nginx  ##启动前查看是否有其他服务占用80端口(Apache)

[root@zabbix-agent1 ~]# netstat -lntup|grep nginx

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      76182/nginx: master

[root@zabbix-agent1 ~]# vim /etc/nginx/conf.d/default.conf

    location /nginx_status {

        stub_status on;

        access_log off;

        allow 127.0.0.1;

        deny all;

    }

[root@zabbix-agent1 ~]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@zabbix-agent1 ~]# nginx -s reload

浏览器查看http://10.0.0.101/nginx_status或者

[root@zabbix-agent1 ~]# curl http://10.0.0.101/nginx_status

中文字符集乱码问题

[root@zabbix-server ~]# cd /usr/share/zabbix/fonts/

[root@zabbix-server fonts]# rz simkai.ttf

[root@zabbix-server fonts]# vim /usr/share/zabbix/include/defines.inc.php  ##修改两处

#define('ZBX_FONT_NAME', 'graphfont');

define('ZBX_FONT_NAME', 'simkai');

#define('ZBX_GRAPH_FONT_NAME',          'graphfont'); // font file name

define('ZBX_GRAPH_FONT_NAME',           'simkai'); // font file name

[root@zabbix-server fonts]# systemctl restart zabbix-server

自定义监控php-fpm状态

Agent端:

[root@zabbix-agent1 ~]# yum install -y php php-fpm

[root@zabbix-agent1 ~]# systemctl start php-fpm

[root@zabbix-agent1 ~]# netstat -lntup|grep 9000

tcp      0    0 127.0.0.1:9000       0.0.0.0:*         LISTEN      64086/php-fpm: mast

         include        fastcgi_params;

    }

[root@zabbix-agent1 ~]# vim /usr/share/nginx/html/index.php

<?php

        phpinfo();

?>

浏览器http://10.0.0.101/index.php能否成功

[root@zabbix-agent1 ~]# vim /etc/php-fpm.d/www.conf

pm.status_path = /phpfpm_status

[root@zabbix-agent1 ~]# systemctl restart php-fpm

[root@zabbix-agent1 ~]# vim /etc/nginx/conf.d/default.conf

   location ~ ^/(phpfpm_status)$ {

        include fastcgi_params;

        fastcgi_pass    127.0.0.1:9000;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

   }

[root@zabbix-agent1 ~]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@zabbix-agent1 ~]# nginx -s reload

浏览器http://10.0.0.101/phpfpm_status或者curl http://10.0.0.101/phpfpm_status

自定义监控mysql

Agent端:

[root@zabbix-agent1 ~]# yum install -y mariadb-server

[root@zabbix-agent1 ~]# systemctl start mariadb

[root@zabbix-agent1 ~]# netstat -lntup|grep 3306

tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      31688/mysqld

[root@zabbix-agent1 ~]# yum install -y https://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm

[root@zabbix-agent1 ~]# rpm -ql percona-release

/etc/pki/rpm-gpg/RPM-GPG-KEY-Percona

/etc/yum.repos.d/percona-release.repo

/usr/share/doc/percona-release-0.1

/usr/share/doc/percona-release-0.1/RPM-GPG-KEY-Percona

[root@zabbix-agent1 ~]# yum install -y percona-zabbix-templates

[root@zabbix-agent1 ~]# rpm -ql percona-zabbix-templates

/var/lib/zabbix/percona

/var/lib/zabbix/percona/scripts

/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh

/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php

/var/lib/zabbix/percona/templates

/var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf

/var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml

[root@zabbix-agent1 ~]# vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php

$mysql_user = 'root';

$mysql_pass = '';

$mysql_port = 3306;

[root@zabbix-agent1 ~]# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/

[root@zabbix-agent1 ~]# systemctl restart zabbix-agent

由于agent端mariadb没有数据，监控也没有值，只能在server端测试

[root@zabbix-agent1 ~]# cd /var/lib/

[root@zabbix-agent1 lib]# scp -r zabbix/ [email protected]:/var/lib/

Server端：

[root@zabbix-server ~]# ls /var/lib/zabbix

Percona

[root@zabbix-server scripts]# zabbix_get -s 10.0.0.102 -k MySQL.Threads-connected

zabbix_get [82941]: Check access restrictions in Zabbix agent configuration

[root@zabbix-server ~]# vim /etc/zabbix/zabbix_agentd.conf

Server=10.0.0.102

[root@zabbix-server scripts]# systemctl restart zabbix-agent

[root@zabbix-server scripts]# zabbix_get -s 10.0.0.102 -k MySQL.Threads-connected

剩下就是导入模板和添加主机、关联主机。

自定义监控Redis

[root@zabbix-agent1 zabbix_agentd.d]# vim redis_status.conf

UserParameter=redis_status[*],/bin/bash /etc/zabbix/scripts/redis_status.sh "$1"

[root@zabbix-agent1 zabbix_agentd.d]# systemctl restart zabbix-agent

Server端：

[root@zabbix-server scripts]# zabbix_get -s 10.0.0.101 -k redis_status[used_cpu_sys]

剩下就是导入模板和添加主机、关联主机。

自定义监控Memcached

[root@zabbix-agent2 ~]# yum install -y memcached

[root@zabbix-agent2 ~]# systemctl start memcached

[root@zabbix-agent2 ~]# netstat -lntup|grep 11211

[root@zabbix-agent2 scripts]# chmod +x memcached.sh

[root@zabbix-agent2 scripts]# cd /etc/zabbix/zabbix_agentd.d/

[root@zabbix-agent2 zabbix_agentd.d]# vim memcache_status.conf

[root@zabbix-agent2 zabbix_agentd.d]# cat memcache_status.conf

UserParameter=memcached_status[*],/bin/bash /etc/zabbix/scripts/memcached_status.sh "$1"

Server端：

[root@zabbix-server ~]# zabbix_get -s 10.0.0.103 -k memcached_status[pid]

58548

[root@zabbix-server ~]# zabbix_get -s 10.0.0.103 -k memcached_status[curr_connections]

剩下就是导入模板和添加主机、关联主机。

自定义监控Tomcat
