TL;DR Tech Tips

Getting an HTTP URL to return JSON data without using curl

Q: Is there a way to get a URL to return JSON data without using the curl command?

A: Yes, just make sure to URL encode the string so it’s a valid hyperlink. For example:


Aggregations over specific time periods

Q: I need to do aggregations over events grouped by specific time periods (weekdays, months and hours) to get the most popular dayweek for an event. How do I do this?

A: Custom grouping periods are currently not supported, so a good workaround for now is to add new tags to the data model such as weekday (with values 1-7), month (1-12) and dayhour (0-23). This allows you to do GROUP BYs over these tags.

Shutting down InfluxDB gracefully

Q: How do I shutdown InfluxDB gracefully?

A: If installed as a service, execute:

service influxdb stop

…otherwise send SIGTERM to the influxd process.
