perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Phil,

That is usually due to a mixture of HTTP and HTTPS. I think it might be due to the fact your esmond URL is http:// whereas you are likely visiting MaDDash using an https address. It’s usually either the esmond URL or the graph URL…but the graph URL is a relative path by default so that suavely only breaks if someone changes it. 

Hope that helps,

Andy

Hi,

I feel like this has been asked a number of times but I couldn't easily
find the answer.

My perfSONAR 5 MaDDash grid is working well, reflecting real up/down
state of the net.  Using Archive, I can see the history graphs between
various hosts.

BUT, when I click on one of the small green squares, The graphs page
opens, as it should, but in the lower portion of the page is a red
banner, with Error Loading Data. (and no graphs appear).  Also the
Source and Destination blocks are empty.

Things tried, disable selinux, checked opensearch is happy, tried it on
a different OS version, (both R9 and D10 have the same issue).

Suggestions anyone?

Phil

A minimized json file only looking at RTT, this file is 'published' and
'remote add' on MaDDash server.  Archive and MaDDash are on the same system
