title: TCollector 写入
|

|

|
||
import TCollector from "../14-reference/_tcollector.mdx"
|
||
|
||
TCollector 是 openTSDB 的一部分，它用来采集客户端日志发送给数据库。
|
||
|
||
只需要将 TCollector 的配置修改指向运行 taosAdapter 的服务器域名（或 IP 地址）和相应端口即可将 TCollector 采集的数据存在到 TDengine 中，可以充分利用 TDengine 对时序数据的高效存储查询性能和集群处理能力。
|
||
|
||
## 前置条件
|
||
|
||
要将 TCollector 数据写入 TDengine 需要以下几方面的准备工作。
|
||
- TDengine 集群已经部署并正常运行
|
||
- taosAdapter 已经安装并正常运行。具体细节请参考 [taosAdapter 的使用手册](/reference/taosadapter)
|
||
- TCollector 已经安装。安装 TCollector 请参考[官方文档](http://opentsdb.net/docs/build/html/user_guide/utilities/tcollector.html#installation-of-tcollector)
|
||
|
||
## 配置步骤
|
||
<TCollector />
|
||
|
||
## 验证方法
|
||
|
||
重启 taosAdapter：
|
||
|
||
```
|
||
sudo systemctl restart taosadapter
|
||
```
|
||
|
||
手动执行 `sudo ./tcollector.py`
|
||
|
||
等待数秒后使用 TDengine CLI 查询 TDengine 是否创建相应数据库并写入数据。
|
||
|
||
```
|
||
taos> show databases;
|
||
name | created_time | ntables | vgroups | replica | quorum | days | keep | cache(MB) | blocks | minrows | maxrows | wallevel | fsync | comp | cachelast | precision | update | status |
