架构原理

Collectd(数据采集,配置Server连接InfluxDB的25826端口) -> InfluxDB(数据存储,启用collectd插件监听25826端口) —> Grafana(数据展示)

• Collectd ： C 语言开发的一个守护(daemon)进程，周期性收集统计数据和存储，拥有丰富的插件包括监控Ceph,DRBD,OpenLDAP,ZK等，类似statD(graphite也可以用来采集数据，不过展示功能没有Grafana丰富)，数据可以存储在Kafka,InfluxDB，OpenTSDB等上
• InfluxDB: GO开发的开源分布式时序数据库，适合存储指标，时间，分析等数据
• Grafana： 是一个开源的，具有丰富指标仪表盘的数据展示和图表编辑工具，支持Graphite,Elasticsearch,OpenTSDB,Prometheus和influxDB,Zabbix等

Collectd

1. 安装collectd

1. 配置collectd
   PHP

   vim /etc/collectd.conf BaseDir "/opt/collectd" PIDFile "/run/collectd.pid" Hostname "host.example.com" Interval 60 <loadplugin df> Interval 120 </loadplugin> LoadPlugin disk LoadPlugin interface LoadPlugin load LoadPlugin memory LoadPlugin network LoadPlugin processes LoadPlugin users <plugin interface> Interface "eth1" IgnoreSelected false </plugin> <plugin network> Server "10.44.38.244" "25826" </plugin>

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

   vim /etc/collectd.conf BaseDir "/opt/collectd" PIDFile "/run/collectd.pid" Hostname "host.example.com" Interval 60 <loadplugin df> Interval 120 </loadplugin> LoadPlugin disk LoadPlugin interface LoadPlugin load LoadPlugin memory LoadPlugin network LoadPlugin processes LoadPlugin users <plugin interface> Interface "eth1" IgnoreSelected false </plugin> <plugin network> Server "10.44.38.244" "25826" </plugin>

2. 说明
   默认collectd进程会每10s中调用注册在配置文件中的插件，默认全局参数interval＝10s(10s上报一次数据到influxdb等)，针对不同的插件可以配置不同的搜集数据的时间间隔interval

InfluxDB

1. 安装并启动服务
   PHP

   cat < <EOF | sudo tee /etc/yum.repos.d/influxdb.repo [influxdb] name = InfluxDB Repository - RHEL \$releasever baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable enabled = 1 gpgcheck = 1 gpgkey = https://repos.influxdata.com/influxdb.key EOF yum -y install influxdb service influxdb start 启动后TCP端口:8083 为InfluxDB 管理控制台 TCP端口:8086 为客户端和InfluxDB通信时的HTTP API 启动后InfluxDB用户认证默认是关闭的，先创建用户:geekwolf geekwolf 命令行输入influx

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

   cat < <EOF | sudo tee /etc/yum.repos.d/influxdb.repo [influxdb] name = InfluxDB Repository - RHEL \$releasever baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable enabled = 1 gpgcheck = 1 gpgkey = https://repos.influxdata.com/influxdb.key EOF yum -y install influxdb service influxdb start 启动后TCP端口:8083 为InfluxDB 管理控制台   TCP端口:8086 为客户端和InfluxDB通信时的HTTP API 启动后InfluxDB用户认证默认是关闭的，先创建用户:geekwolf geekwolf 命令行输入influx

2. 基本使用
   PHP

   [root@geekwolf ~]# influx Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring.

3. 启用认证
   PHP

   修改配置文件启用认证 sed -i ’s#auth-enabled = false#auth-enabled = true#g’ /etc/influxdb/influxdb.conf service influxdb restart

   1 2 3 4

   修改配置文件启用认证 sed -i ’s#auth-enabled = false#auth-enabled = true#g’ /etc/influxdb/influxdb.conf service influxdb restart

配置InfluxDB支持Collectd

1. 修改配置
   PHP

   vim /etc/influxdb/influxdb.conf [collectd] enabled = true bind-address = "10.44.38.244:25826" database = "collectdb" typesdb = "/opt/collectd/share/collectd/types.db" batch-size = 5000 batch-pending = 10 batch-timeout = "10s" read-buffer = 0 service influxdb restart

   1 2 3 4 5 6 7 8 9 10 11 12 13

   vim /etc/influxdb/influxdb.conf [collectd] enabled = true bind-address = "10.44.38.244:25826" database = "collectdb" typesdb = "/opt/collectd/share/collectd/types.db" batch-size = 5000 batch-pending = 10 batch-timeout = "10s" read-buffer = 0 service influxdb restart

2. 查看metrics信息

安装配置Grafana

访问地址:http://10.44.38.244:3000 默认账号为admin admin
关闭Grafana注册功能:

• 添加InfluxDB数据源

• 添加ping图的例子

• 图表展示

详细demo可参考:http://play.grafana.org/

问题总结

问题 :在使用influxdb0.12.x版本和Grafana2.6时出现multiple query syntax的bug,原因是influxdb的apiwent

解决方法: 升级Grafana2.6到Grafana3.0-beta1以上版本
