由于公司监控需要 需对线上所有TOMCAT进行 GC监控 故采用已下方案:
1：通过jmxmon采集tomcat服务状态 上报给open-falcon-agent
2：open-falcon通过api接口上报数据给grafana
3: grafana配置数据源连接open-falcon-2.0 并进行数据展示
环境准备：
部署open-falcon-2.0 不啰嗦直接上命令 不懂自己gb:
yum install -y redis
yum install -y mysql-server
初始化数据库：
cd /tmp/ && git clone https://github.com/open-falcon/falcon-plus.git
cd /tmp/falcon-plus/scripts/mysql/db_schema/
mysql -h 127.0.0.1 -u root -p < 1_uic-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 2_portal-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 3_dashboard-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 4_graph-db-schema.sql
mysql -h 127.0.0.1 -u root -p < 5_alarms-db-schema.sql
rm -rf /tmp/falcon-plus/
下载二进制包:
https://github.com/open-falcon/falcon-plus/releases #这是地址我下载的是open-falcon-v0.2.1.tar.gz
环境变量设置:
export FALCON_HOME=/data/open-falcon-0.21
export WORKSPACE=$FALCON_HOME/open-falcon
source /etc/profile
tar zxvf open-falcon-v0.2.1.2.tar.gz -C /data/open-falcon-0.21/open-falcon
cd /data/open-falcon-0.21/open-falcon
./open-falcon start
./open-falcon check
记得更改mysql 用户名和密码 如果不一致 默认为空
安装前端代码也就是dashboard:
cd /data/open-falcon-0.21/open-falcon
git clone https://github.com/open-falcon/dashboard.git
yum install -y python-virtualenv
yum install -y python-devel
yum install -y openldap-devel
yum install -y mysql-devel
yum groupinstall "Development tools"
cd /data/open-falcon-0.21/open-falcon/dashboard
virtualenv ./env
./env/bin/pip install -r pip_requirements.txt
如无报错说明安装完成
dashboard的配置文件为： 'rrd/config.py'，请根据实际情况修改
## API_ADDR 表示后端api组件的地址
API_ADDR = "http://127.0.0.1:8080/api/v1"
## 根据实际情况，修改PORTAL_DB_*, 默认用户名为root，默认密码为""
## 根据实际情况，修改ALARM_DB_*, 默认用户名为root，默认密码为""
启动dashboard:
cd /data/open-falcon-0.21/open-falcon/dashboard
./control start
./control status|tail
port:8081 可浏览器访问
Grafana4.5.2 部署：
wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.6.0-1.x86_64.rpm
yum localinstallgrafana-4.6.0-1.x86_64.rpm
vim /etc/grafana/grafana.ini
/etc/init.d/grafana-server restart
访问地址:falcon.uxin001.com:3000
访问：https://grafana.com/plugins/fastweb-openfalcon-datasource/installation
解压至/var/lib/grafana/plugins 下 如图:此配置要检查配置文件下的plugins = /var/lib/grafana/plugins配置
登录grafana4.5 增加数据源:
此处注意:http://192.168.5.161:8080/api/v1/grafana 为open-falcon-0.21版本的api接口 和0.1版本有所区别 建议安装最新版本open-falcon
为监控机器添加变量模板 看图说话:
grafana暂时不支持open-falcon数据的报警 故我们还是用的falcon邮件和微信报警 具体详见另一篇文章
jmxmon部署:
部署之前请确保tomcat开启JMX
vim /data/soft/tomcat_home/bin/catalina.sh
# ----- Execute The Requested Command -----------------------------------------
在此之上添加：
CATALINA_OPTS="$CATALINA_OPTS
-Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=192.168.5.161
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
hostname:本地IP
port:自定义端口 给远程连接使用
authenticate=false 不开启远程用户名和密码验证
重启tomacat
https://github.com/toomanyopenfiles/jmxmon/releases/tag/v0.0.2 #jmxmon下载地址
tar zxvf jmxmon-v0.0.2.tar.gz -C /data/open-falcon/falcon-jmxmon/
配置参考:
cat conf.properties
# the working dir
workDir=./
# localhost jmx ports, split by comma
jmx.ports=9999
# agent port url
agent.posturl=http://127.0.0.1:1988/v1/push
./control start 启动
./control status|tail
登录open-falcon查看 Gc数据是否过来
