Metric shows all data as "empty"

Hello,

I have an active alarm on one of my servers for apps.files (current value: “-”, alarm: used_file_descriptors, 1315 hours ago) that is simply not being reseted. Even after rebooting the server, nothing seems to be updated on this page.

When I click on “Go to Chart” on the alarm, all data on the netdata.cloud ui is being presented as “<!> empty” (<!> being actually kind of a ‘warning’ sign), for every single category. After that, anything else I click on the UI starts presenting me with these “empty” values, from the main war room to the node listing. By checking the javascript console on the browser, I’m seeing a few CORS errors, a few 429 (apparently for sentry) and a couple of 400 (one example: /api/v1/spaces/xxx/rooms/yyy/data).

I’ve tried this on Google Chrome 87.0.4280.141 x86_64 (MacOS 11.1) and on Safari 14.0.2, with the exact same results.

After logging out and logging in again, everything works, until I try to go to the same “Go to Chart” page. Then it’s back to “empty” again.

Hey @Mawkee

Thank you very much for your detailed bug description

The active alarm is a known issue Incorrect active alarms in Cloud · Issue #4 · netdata/netdata-cloud · GitHub

When I click on “Go to Chart” on the alarm, all data on the netdata.cloud ui is being presented as “<!> empty”

What can possibly cause this is when you click on “Go to Chart”, the selected time window is adjusted to show the period of the alarm and since 1315 hours ago could be more than what your agent retains it causes empty charts.

You can try to adjust your time window and see if that fixes the problem.

We are going to look at it on our end as well, it would be useful for us if you can share your spaceID. (send me a direct message Profile - Leonidas_Vrachnis - Netdata Community)

If that is the case, we will need to improve our UI @Manos_Saratsis.

Hello Leonidas!

Adjusting the time window seems to have done the trick. Thanks :slight_smile:

I’ll reach out to pass you my spaceid

@Leonidas_Vrachnis , sorry about this, but I can’t seem to find any way to send you a direct message. Maybe it’s related to me being a new user or something like that?
