InfluxDB、Grafana 与 influxdata其它软件，构建性能监控平台

介绍

Telegraf 类似agent，可收集系统和服务的统计数据，并写入到 InfluxDB 数据库

InfluxDB 时序数据库

Chronograf web控制面板

Kapacitor 监控报警，处理时序数据

安装

https://portal.influxdata.com/downloads

InfluxDB

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.5.2.x86_64.rpm
sudo yum localinstall influxdb-1.5.2.x86_64.rpm

暂不更改InfluxDB配置直接启动

[root@iZ2zecfp183kc1hq3nfk3kZ influxdb]# service influxdb start
Starting influxdb...
influxdb process was started [ OK ]

Telegraf

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.6.1-1.x86_64.rpm
sudo yum localinstall telegraf-1.6.1-1.x86_64.rpm

修改Telegraf的hostname

vi /etc/telegraf/telegraf.conf
hostname = "xxx.xxx.xxx.xxx"

[root@iZ2zecfp183kc1hq3nfk3kZ /]# service telegraf start
Starting the process telegraf [ OK ]
telegraf process was started [ OK ]

Kapacitor

wget https://dl.influxdata.com/kapacitor/releases/kapacitor-1.4.1.x86_64.rpm
sudo yum localinstall kapacitor-1.4.1.x86_64.rpm

[root@iZ2zecfp183kc1hq3nfk3kZ kapacitor]# service kapacitor start

Starting the process kapacitor [ OK ]
kapacitor process was started [ OK ]

Chronograf

web面板我下载的windows版本

https://dl.influxdata.com/chronograf/releases/chronograf-1.4.4.2_windows_amd64.zip
unzip chronograf-1.4.4.2_windows_amd64.zip

直接运行chronograf.exe启动

使用

Chronograf 默认监听8888端口

访问http://127.0.0.1:8888

1、设置InfluxDb的ip+port

2、查看当前有Telegraf的Host

3、查看dashboard
点击host 和 apps列下面的 mysql，nginx可以查看当前的统计面板

Telegraf配置

telegraf已经实现了很多服务的监听，例如常见的 mysql、nginx、apache、redis

nginx监控

配置nginx我们只需要增加nginx的配置

vi /etc/telegraf/telegraf.conf
# Read Nginx's basic status information (ngx_http_stub_status_module)
    [[inputs.nginx]]
      ## An array of Nginx stub_status URI to gather stats.
      urls = ["http://localhost/server_status"]

      ## Optional TLS Config
      # tls_ca = "/etc/telegraf/ca.pem"
      # tls_cert = "/etc/telegraf/cert.pem"
      # tls_key = "/etc/telegraf/key.pem"
      ## Use TLS but skip chain & host verification
      # insecure_skip_verify = false

      ## HTTP response timeout (default: 5s)
      response_timeout = "5s"
