• InfluxDB支持collectd数据收集的配置


    一、常用脚本

    influx
    show databases
    #如果没有collectdb数据库则执行以下脚本创建
    create database collectdb

    #修改配置文件
    vim /etc/influxdb/influxdb.conf

    二、修改配置信息如下

    [collectd]
                    enabled = true
                    bind-address = "127.0.0.1:25826"      #InfluxDB的安装服务器ip
                    database = "collectdb"
                    typesdb = "/usr/share/collectd/types.db" #查找一下types.db文件不一定在这个路径,如果路径配置错误就不能监听成功(与collectd的配置保持一致)
                    batch-size = 5000
                    batch-pending = 10
                    batch-timeout = "10s"
                    read-buffer = 0
    重启InfluxDB服务
    [root@betterday collectd]# systemctl restart influxdb.service #重启InfluxDB服务
    [root@betterday collectd]# netstat -anp| grep 25826 #查看端口是否已监听,如果有则代表启动正常
    udp        0      0 127.0.0.1:25826         0.0.0.0:*                           22580/influxd  

     确认数据:

    [root@betterday collectd]# influx
    Connected to http://localhost:8086 version 1.2.4
    InfluxDB shell version: 1.2.4
