监控CPU负载、Nginx、TCP、PHP、Memcached、Redis、Mysql、Tomcat

监控CPU负载

Agent端:

[[email protected] ~]# 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:

[[email protected] ~]# zabbix_get -s 10.0.0.101 -k cpu_load1

0.00

[[email protected] ~]# zabbix_get -s 10.0.0.101 -k cpu_load5

0.01

[[email protected] ~]# zabbix_get -s 10.0.0.101 -k cpu_load15

0.05

Step1(创建模板):

Step2(关联主机):

监控mysql

Agent端:

[[email protected] ~]# yum install -y mariadb-server

[[email protected] ~]# systemctl start mariadb

[[email protected] ~]# netstat -lntup|grep 3306

[[email protected] ~]# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/

[[email protected] ~]# 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

[[email protected] ~]# cd /var/lib/

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

Server端：

[[email protected] ~]# ls /var/lib/zabbix

Percona
