本文介绍了在Grafana上使用InfluxDB每秒计算请求的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用telegraf插件nginx读取Nginx的基本状态信息(ngx_http_stub_status_module)
I use telegraf plugin nginx to read Nginx's basic status information (ngx_http_stub_status_module)
这是我的查询
原始sql:
SELECT derivative(mean("requests"), 1s) FROM "nginx" WHERE $timeFilter GROUP BY time($interval) fill(null)
这是我的数据
time accepts active handled host port reading requests server waitingwriting
1464921070000000000 7 1 7 hysm 80 0 17 localhost 0 1
1464921080000000000 8 1 8 hysm 80 0 19 localhost 0 1
1464921090000000000 8 1 8 hysm 80 0 20 localhost 0 1
1464921100000000000 8 1 8 hysm 80 0 21 localhost 0 1
但是requestPerSecond是0.083,我的查询出了什么问题?
but requestPerSecond is 0.083, what is wrong with my query?
推荐答案
假设您要处理一个计数器,那么您想要的查询就是
Assuming that you're dealing with a a counter, the query you're going to want is
SELECT derivative(max(requests))
FROM "nginx"
WHERE $timeFilter
GROUP BY time($interval)
