OpenTSDB 安装

下载目录

https://github.com/OpenTSDB/opentsdb/releases
https://github.com/OpenTSDB/opentsdb/releases/download/v2.4.0/opentsdb-2.4.0.noarch.rpm

安装 GnuPlot

yum install gnuplot -y

直接安装OpenTSDB会报错

[root@ecs-t-001-0001 openTSDB]# rpm -ivh opentsdb-2.4.0.noarch.rpmerror: Failed dependencies: gnuplot is needed by opentsdb-2.4.0-1.noarch

安装OpenTSDB

[root@ecs opt]# rpm -ivh opentsdb-2.4.0.noarch.rpm

默认配置目录

    /etc/opentsdb - Configuration files /tmp/opentsdb - Temporary cache files /usr/share/opentsdb - Application files /usr/share/opentsdb/bin - The "tsdb" startup script that launches a TSD or commandline tools /usr/share/opentsdb/lib - Java JAR library files /usr/share/opentsdb/plugins - Location for plugin files and dependencies /usr/share/opentsdb/static - Static files for the GUI /usr/share/opentsdb/tools - Scripts and other tools /var/log/opentsdb - Logs

修改配置

进入目录 /usr/share/opentsdb/etc/opentsdb 修改配置文件 opentsdb.conf

> vim opentsdb.conftsd.storage.hbase.zk_quorum = zk:2181
tsd.network.port = 10080
tsd.http.staticroot = /usr/share/opentsdb/static/
tsd.http.cachedir = /tmp/opentsdb
tsd.core.plugin_path = /usr/share/opentsdb/plugins

初始化OpenTSDB表

进入目录/usr/share/opentsdb/tools，修改create_table.sh

我们加入的内容

HBASE_HOME=/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/hbase
COMPRESSION=SNAPPY

全部内容

[root@ecs tools]# cat create_table.sh

启动TSDB

nohup sh /usr/share/opentsdb/bin/tsdb tsd >tsdb-start.log &

访问页面

写入数据

上面如果没有设置 tsd.core.auto_create_metrics = true 参数时，需要手动创建 metric

tsdb mkmetric sys.cpu.user

否则会提示异常如下

[root@ecs-t-001-0002 ~]# telnet ip port
Escape character is '^]'.
put sys.cpu.user 1588302377 42.5 host=webserver01 cpu=0
put: unknown metric: No such name for 'metrics': 'sys.cpu.user'

加入两条数据，我们使用 telnet 方式添加数据，

put sys.cpu.user 1588292377 45.5 host=webserver01 cpu=0
put sys.cpu.user 1588302377 41.5 host=webserver01 cpu=0

再web页面我们简单查询看一下数据，右下角的一根线就是我们刚刚插入的两个点连成的线

这回我们插入四条数据，写入两个host

put sys.cpu.user 1588292377 45.5 host=webserver01 cpu=0
put sys.cpu.user 1588302377 41.5 host=webserver01 cpu=0
put sys.cpu.user 1588292377 12.5 host=webserver02 cpu=0
put sys.cpu.user 1588302377 80.5 host=webserver02 cpu=0

我们再指定tags查询看看效果，指定webserver02小时如下，结果是从12.5-80.5两个点没问题

看下webserver01,数据也没问题

至此，服务安装与初步使用介绍完成，下一步介绍下Api接口使用
