监控CPU负载、Nginx、TCP、PHP、Memcached、Redis、Mysql、Tomcat
监控CPU负载
Agent端:
# 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:
# zabbix_get -s 10.0.0.101 -k cpu_load1
0.00
# zabbix_get -s 10.0.0.101 -k cpu_load5
0.01
# zabbix_get -s 10.0.0.101 -k cpu_load15
0.05
Step1(配置-->模板-->创建模板):
Step2(创建克隆监控项):
Step3(创建克隆触发器):
Step4(创建图形):
Step5(添加模板如下图):
ab压测使CPU有波动
Server端:
# yum install -y httpd-tools
# ab -n 10000 -c 100 http://10.0.0.101/index
Agent端:
# yum install -y httpd
# systemctl start httpd
# vim /var/www/html/index.html
# curl --head http://10.0.0.101/index.html
监控Nginx服务
Agent端:
#vim /etc/yum.repos.d/nginx.repo
#cat /etc/yum.repos.d/nginx.repo
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/x86_64/
gpgcheck=0
enabled=1
#rpm -qa | grep centos-release
centos-release-7-4.1708.el7.centos.x86_64
# yum install -y nginx
# systemctl start nginx##启动前查看是否有其他服务占用80端口(Apache)
# netstat -lntup|grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 76182/nginx: master
# vim /etc/nginx/conf.d/default.conf
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# nginx -s> 浏览器查看http://10.0.0.101/nginx_status或者
# curl http://10.0.0.101/nginx_status

Step4(添加图形):
Step5(为主机添加模板):
监控TCP信息状态
Agent端:
# cd /etc/zabbix/scripts/
#vim tcp_status.sh
# chmod +x tcp_status.sh
# sh -x tcp_status.sh ESTAB##测试脚本
+ '[' 1 -ne 1 ']'
+ tcp_status_fun ESTAB

# systemctl restart zabbix-agent
Server端
# zabbix_get -s 10.0.0.101 -k tcp_status ##出现这种错误到客户端删掉/opt/ss.txt文件
/etc/zabbix/scripts/tcp_status.sh: line 18: /tmp/ss.txt: Permission denied

# zabbix_get -s 10.0.0.101 -k tcp_status##检验键值

Step4(关联主机):
中文字符集乱码问题
# cd /usr/share/zabbix/fonts/
# rz simkai.ttf
# vim /usr/share/zabbix/include/defines.inc.php##修改两处

# systemctl restart zabbix-server
监控php-fpm状态
Agent端:
# yum install -y php php-fpm
# systemctl start php-fpm
# netstat -lntup|grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 64086/php-fpm: mast
# vim /etc/nginx/conf.d/default.conf

Step2(关联主机):
监控mysql
Agent端:
# yum install -y mariadb-server
# systemctl start mariadb
# netstat -lntup|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 31688/mysqld
# yum install -y https://www.percona.com/redir/downloads/percona-release/redhat/latest/percona-release-0.1-4.noarch.rpm
# 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
# yum install -y percona-zabbix-templates
# 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
# vim /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php
$mysql_user = 'root';
$mysql_pass = '';
$mysql_port = 3306;
# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/
# 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
# cd /var/lib/
# scp -r zabbix/ root@10.0.0.102:/var/lib/
Server端：
# ls /var/lib/zabbix
Percona
# zabbix_get -s 10.0.0.102 -k MySQL.Threads-connected
zabbix_get : Check access restrictions in Zabbix agent configuration
# vim /etc/zabbix/zabbix_agentd.conf
Server=10.0.0.102
# systemctl restart zabbix-agent
# 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。

# zabbix_get -s 10.0.0.101 -k redis_status
0.10
剩下就是导入模板和添加主机、关联主机。

58548
# zabbix_get -s 10.0.0.103 -k memcached_status

剩下就是导入模板和添加主机、关联主机。
监控Tomcat
