20: zabbix监控java jvm原理

tomcat weblogic jboss resin
tomcat：
开启监控接口

#安装tomcat
rpm -ivh jdk-8u102-linux-x64.rpm
mkdir /app
tar xf apache-tomcat-8.0.27.tar.gz -C /app/
/app/apache-tomcat-8.0.27/bin/startup.sh
#增加一行
vim /app/apache-tomcat-8.0.27/bin/catalina.sh
CATALINA_OPTS="$CATALINA_OPTS -
Dcom.sun.management.jmxremote -
Djava.rmi.server.hostname=10.0.0.8 -
Dcom.sun.management.jmxremote.port=12345 -
Dcom.sun.management.jmxremote.ssl=false -
Dcom.sun.management.jmxremote.authenticate=false"
#重启生效
/app/apache-tomcat-8.0.27/bin/shutdown.sh
/app/apache-tomcat-8.0.27/bin/startup.sh
#检验
[root@web01 opt]# netstat -lntup|grep 12345
tcp6 0 0 :::12345 :::*
LISTEN 100141/java

安装zabbix-java-gateway来监控jvm

yum install zabbix-java-gateway.x86_64 -y
systemctl start zabbix-java-gateway.service
systemctl enable zabbix-java-gateway.service

修改zabbix-server的配置文件

vim /etc/zabbix/zabbix_server.conf
JavaGateway=127.0.0.1
JavaGatewayPort=10052
StartJavaPollers=3
systemctl restart zabbix-server.service

添加监控

21: zabbix性能优化

性能不足的时候：经常出现误报，断图，还有其他报警

优化：

数据库优化：业务类型 写多读少

存储引擎：innodb --> tokudb
版本 mariadb 5.5 --> mysql 5.7
存储：机械硬盘--->固态硬盘
去掉无用的监控项
增加取值间隔，建议60s
减少数据的保留周期，重要监控项保留90d,其他的一律3d
mysql的分区和分表

zabbix-server服务优化

进程数
缓存大小

22: zabbix低级自动发现

新增一个监控项原型
增加一个UserParameter=xxxx[*],cmd $1
监控每块网卡的mac地址
[root@web01 zabbix_agent2.d]# cat zbx_net.conf
UserParameter=net_mac[*],ifconfig $1|awk '/ether/{print $$2}'
[root@zabbix-server ~]# zabbix_get -s 10.0.0.8 -k net_mac[eth1]
00:0c:29:2e:16:18

通过低级自动发现监控mysql多实例

准备环境mysql多实例

cp /etc/my.cnf /etc/my3307.cnf
vim /etc/my3307.cnf
[mysqld]
datadir=/data/3307/
socket=/data/3307/mysql.sock
port=3307
user=mysql
symbolic-links=0
[mysqld_safe]
log-error=/data/3307/mysqld.log
pid-file=/data/3307/mysqld.pid
sed '/^$/d' /etc/my3307.cnf
sed -i '/^$/d' /etc/my3307.cnf
cp /etc/my3307.cnf /etc/my3308.cnf
sed -i 's#3307#3308#g' /etc/my3308.cnf
cat /etc/my3308.cnf
mysql_install_db --user=mysql --defaultsfile=/etc/my3307.cnf
mysql_install_db --user=mysql --defaultsfile=/etc/my3308.cnf
mysqld_safe --defaults-file=/etc/my3307.cnf &
mysqld_safe --defaults-file=/etc/my3308.cnf &
mysqladmin -uroot -h 127.0.0.1 -P 3307 password
'123456'
mysql -uroot -p123456 -h 127.0.0.1 -P 3307
mysqladmin -uroot -h 127.0.0.1 -P 3308 password
'123456'
mysql -uroot -p123456 -h 127.0.0.1 -P 3308

创建低级自动发现规则

#自定义规则的监控项
vim /etc/zabbix/zabbix_agent2.d/zbx_mysql.conf
UserParameter=mysql.port.discovery,/bin/bash
/server/scripts/mysql_port_discovery.sh
#脚本
vim /server/scripts/mysql_port_discovery.sh
#!/bin/bash
#mysql low-level discovery
res=`netstat -lntp|awk -F "[ :\t]+" '/mysqld/{print$5}'`
port=($res)
printf '['

for key in ${!port[@]}
do
	if [[ "${#port[@]}" -gt 1 && "${key}" -ne "$((${#port[@]}-1))" ]];then
		printf '{'
		printf "\"{#MYSQLPORT}\":\"${port[${key}]}\"},"
	else [[ "${key}" -eq "((${#port[@]}-1))" ]]
		printf '{'
		printf "\"{#MYSQLPORT}\":\"${port[${key}]}\"}"
	fi
done
printf ']\n'

#重启
systemctl restart zabbix-agent2.service
#测试
[root@zabbix-server ~]# zabbix_get -s 10.0.0.8 -kmysql.port.discovery
[{"{#MYSQLPORT}":"3306"},{"{#MYSQLPORT}":"3307"},{"{#MYSQLPORT}":"3308"}]

创建监控项原型

vim zbx_mysql.conf
UserParameter=mysql_alive[*],mysqladmin -uroot -p123456 -h 127.0.0.1 -P $1 ping 2>/dev/null|grep -c alive
#测试
[root@zabbix-server ~]# zabbix_get -s 10.0.0.8 -k mysql_alive[3307]
1

23: zabbix api

api：应用程序接口
什么是调用api
怎么调用api，发起一个http请求

curl "http://apis.juhe.cn/simpleWeather/query?city=昌平&key=3dae6629acd8689e9b12f8bb4f"
{"reason":"查询成功!","result":{"city":"昌平","realtime":
{"temperature":"13","humidity":"15","info":"晴","wid":"
00","direct":"西风","power":"2级","aqi":"67"},"future":

		"host": "10.0.0.8",
		"interfaces": [
			{
			"type": 1,
			"main": 1,
			"useip": 1,
			"ip": "10.0.0.8",
