The compiler was too strict. The inherited interval from an outer query should not have caused the inner query to fail because inherited intervals are only implicitly passed to inner queries that support group by time functionality. Since the inner query with a derivative doesn't support grouping by time and the inner query itself doesn't specify a time, the outer query shouldn't have invalidated the inner query. |

InfluxDB 
An Open-Source Time Series Database
InfluxDB is an open source time series database with no external dependencies. It's useful for recording metrics, events, and performing analytics.
Features
- Built-in HTTP API so you don't have to write any server side code to get up and running.
- Data can be tagged, allowing very flexible querying.
- SQL-like query language.
- Simple to install and manage, and fast to get data in and out.
- It aims to answer queries in real-time. That means every data point is indexed as it comes in and is immediately available in queries that should return in < 100ms.
Installation
We recommend installing InfluxDB using one of the pre-built packages. Then start InfluxDB using:
service influxdb startif you have installed InfluxDB using an official Debian or RPM package.systemctl start influxdbif you have installed InfluxDB using an official Debian or RPM package, and are running a distro withsystemd. For example, Ubuntu 15 or later.$GOPATH/bin/influxdif you have built InfluxDB from source.
Getting Started
Create your first database
curl -XPOST "http://localhost:8086/query" --data-urlencode "q=CREATE DATABASE mydb"
Insert some data
curl -XPOST "http://localhost:8086/write?db=mydb" \
-d 'cpu,host=server01,region=uswest load=42 1434055562000000000'
curl -XPOST "http://localhost:8086/write?db=mydb" \
-d 'cpu,host=server02,region=uswest load=78 1434055562000000000'
curl -XPOST "http://localhost:8086/write?db=mydb" \
-d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'
Query for the data
curl -G "http://localhost:8086/query?pretty=true" --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT * FROM cpu WHERE host='server01' AND time < now() - 1d"
Analyze the data
curl -G "http://localhost:8086/query?pretty=true" --data-urlencode "db=mydb" \
--data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"
