使用Categraf安装clickhouse插件报错

Viewed 50

RT,我想使用N9E对click house进行数据库指标的监控,测试结果结果报错./categraf --test --inputs clickhouse

但是我也没这条查询语句,配置文件里面用户名密码是没问题的,所以权限应该是正常的,想知道是不是默认的连库方式不是用clickhouse-client。。。所以很迷茫,附上clickhouse.toml,麻烦各位大佬帮忙看看

# # collect interval
interval = 15

# Read metrics from one or many ClickHouse servers
[[instances]]

  ## HTTP(s) timeout while getting metrics values
  ## The timeout includes connection time, any redirects, and reading the
  ## response body.
  timeout = 5

已解决。。因为servers使用的是url,所以想用post请求试试,结果报错http只支持8123端口,最终命令如下
curl -X POST "http://ck1:8123" -u default:passwd --data "SELECT cluster, shard_num, host_name FROM system.clusters"
然后修改了servers的端口就成功了,所以clickhouse插件使用的是POST请求而不是click house自带的client连接的,找到原因也是瞎猫碰到死耗子。。不知道日志在哪?journalctl -fu categraf查看也不明不白的

提个pr,嘿嘿,我看代码上是没有打印这个http的请求的错误原因
