perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Hmmm Grafana just sees whatever data is in OpenSearch, so when you install Grafana will not affect what data appears. Is the OpenSearch server its looking at behind a firewall or could I reach it to take a look? 

Also, we have an office hours call next Friday where we could potentially do some interactive debugging if needed.

Thanks,

Andy

Greetings:

I've followed the Grafana cookboook (here:
https://docs.perfsonar.net/grafana_cookbook.html).

I've created and tested the data source and imported the dashboards.

What I'm finding is that Grafana is only displaying data that was
collected after I completed this installation, even though I have data
from before that point.

Specifically, I got Grafana / OpenSearch connected yesterday, but when I
attempted to view 30 days worth of data, I only see graphs for yesterday.

Is this expected behavior?

If I play around with the Grafana query explorer, I can see that the
time range does change as expected, eg:
> 90 day
> {\"range\":{\"pscheduler.start_time\":{\"gte\":1699733443050,\"lte\":1707509443050,\"format\":\"epoch_millis\"}}}
> 7 day
> {\"range\":{\"pscheduler.start_time\":{\"gte\":1706904709764,\"lte\":1707509509764,\"format\":\"epoch_millis\"}}},


But the only data that gets displayed is data from the point of the
Grafana installation.

Is there a way to use Grafana to display all the data from a perfSONAR node?

Thank you.
