Cyanite does not return absolute time range when it out of first resolution
When zooming graph in Grafana, from day 29 and later, there are no data points returned and see an empty graph. Relative time "Last X days/hours" working fine. Absolute time inside range of first resolution, which in our case is 1m:4w, working fine. When trying to get data from absolute time later than last 4 weeks, we get no data points and seeing empty graph. Are you familiar with such behavior?
cyanite.yaml:
engine:
rules:
cyanite.*: ['10s:1d', '1m:4w', '1h:1y']
default: ['1m:4w', '1h:1y']
Examples: Working POST /render(older 4 weeks): target=AIO.DIAG.diag2.cpu.cpu.idle&from=1503888311&until=1504007603&format=json&maxDataPoints=640
Non working POST /render(later than 4 weeks): target=AIO.DIAG.diag2.cpu.cpu.idle&from=1501626994&until=1501686700&format=json&maxDataPoints=640
Is there anyone with any assumption regarding the above? It's working as expected with Graphite, but not with Cyanite.
It has to work, you are absolutely right here.
Unfortunately, I have a lot of things going on at work at the moment, and was contributing to cyanite only during my free time, so I can't really help quickly. Sorry about that.
@avneradania I assume you're using grafana not in a proxy mode or something similar, just describe your setup, if I have more questions I'll ask how more
Our setup works as follows: Grafana uses Graphite data soutce, proxy mode with the address of Graphite-api, which configured with Cyanite port. So, all seems to work when trying to get graph with a range till last 28 days(retrntion is 1m:4w, 1h:1y). When trying to generate graph with a range older than 28 days, nothing is shown.
Just wondering, why do you need graphite-api in this case?.. you could just use it directly...
Nit sure I understood your meaning... Im not familiar with a direct data source for Cyanite in Grafana, but through Graphite data source.
Thanks for the advice. Though, issue happens both with Graphite-API and Cyanite directly.
