简介: Telegraf 是一个用 Go 编写的代理程序,可收集系统和服务的统计数据,并写入到 InfluxDB 数据库。 Telegraf 具有内存占用小的特点,通过插件系统开发人员可轻松添加支持其他服务的扩展。
官网参考地址 https://docs.influxdata.com/telegraf/v0.11/ 软件下载地址: https://influxdata.com/downloads/
1:安装部署
1、下载
2、安装 yum localinstall telegraf-0.11.1-1.x86_64.rpm -y
3、启动服务、添加开机启动 systemctl start telegraf.service service telegraf status systemctl enable telegraf.service
4、查看版本 telegraf --version Telegraf - Version 0.11.1
配置文件位置(默认配置):/etc/telegraf/telegraf.conf
修改telegraf配置文件添加监控项 vim /etc/telegraf/telegraf.conf
#修改监控数据输出位置,本次测试环境本地安装有influxdb, 可以保持默认:urls = ["http://localhost:8086"] 58 [[outputs.influxdb]] 59 ## The full HTTP or UDP endpoint URL for your InfluxDB instance. 60 ## Multiple urls can be specified as part of the same cluster, 61 ## this means that only ONE of the urls will be written to each interval. 62 # urls = ["udp://localhost:8089"] # UDP endpoint example 63 urls = ["http://172.16.7.12:8086"] # required 64 ## The target database for metrics (telegraf will create it if not exists).
2:添加监控项:
1、添加docker 监控项 参考地址: https://github.com/influxdata/telegraf [[inputs.docker]] #Docker Endpoint #To use TCP, set endpoint = "tcp://[ip]:[port]" #To use environment variables (ie, docker-machine), set endpoint = "ENV" endpoint = "unix:///var/run/docker.sock" #Only collect metrics for these containers, collect all if empty #container_names = []
2、zookeeper 监控添加 [[inputs.zookeeper]] servers = ["172.16.7.12:2181"]
3、mesos监控项 [[inputs.mesos]] # Timeout, in ms. timeout = 100 # A list of Mesos masters, default value is localhost:5050. masters = ["localhost:5050"] # Metrics groups to be collected, by default, all enabled. master_collections = ["resources","master","system","slaves","frameworks","messages","evqueue","registrar"]
以上新加3个监控项,可以通过命令测试配置是否成功。 telegraf -config /etc/telegraf/telegraf.conf -input-filter mesos -test telegraf -config /etc/telegraf/telegraf.conf -input-filter docker -test telegraf -config /etc/telegraf/telegraf.conf -input-filter zookeeper -test
3:修改telegraf 服务启动用户,默认用户无法通过sock 获取doker 数据。
[iyunv@ctn-7-11 grafana]# vi /usr/lib/systemd/system/telegraf.service [Unit] Description=The plugin-driven server agent for reporting metrics into InfluxDB Documentation=https://github.com/influxdata/telegraf After=network.target
[Service] EnvironmentFile=-/etc/default/telegraf #User=telegraf #本次测试环境直接改为root User=root ExecStart=/usr/bin/telegraf -config /etc/telegraf/telegraf.conf -config-directory /etc/telegraf/telegraf.d 。。。。。。。
4:重启服务,使配置生效 systemctl daemon-reload systemctl restart telegraf ps -ef|grep telegraf
1、验证
root 7244 4292 0 17:44 pts/0 00:00:00 grep --color=auto telegraf telegraf (默认启动用户)31793 1 0 15:48 ? 00:00:37 /usr/bin/telegraf -config /etc/telegraf/telegraf.conf -config-directory /etc/telegraf/telegraf.d
#启动脚本修改后 root 3283 1 2 17:24 ? 00:00:00 /usr/bin/telegraf -config /etc/telegraf/telegraf.conf -config-directory /etc/telegraf/telegraf.d root 3402 8804 0 17:24 pts/0 00:00:00 grep --color=auto telegraf
