Chart API - 500 code error

[corey_r]

Hello Wavefront experts,

I am experiencing a problem with wavefront api.  The problem started around 5/10/2016.

I used to be able to get the daily data points for passing in the following parameters:

• s : start time = 0 hour for day let's say 5/18/2016 00:00:00 (unix time : 1463529600)
• e : end time = 23rd hour for the same day 5/18/2016 23:00:00 (unix time : 1463612400)
• g : 'd'

Please note that this has always worked for me until recently.

It returns the following error msg: "error='server_error' message='sunnylabs.query.QuerySyntaxException: Query syntax error: End time not after start time'"

Your help is appreciated.

Hi Simon,

Thanks for reaching out to us. The probable reason this is not working is because the time duration between s and e is less than the granularity selected g=d ( day)

This is a known issue with the granularity parameter and our engineering team is working on a fix for it.

In meantime, if you change your end time e to 1463616000 ( 5/19/2016 00:00:00 GMT) your query should work .

Please let me know if this is resolves the issue you are seeing.

Thank you Salil.

I thought I have tried it.  But giving it a try again works.  Appreciate it.

thanks,
