Hi,

Looks like the issue is that you are visiting the page using https, but the graph URL is loading data from the archive using plain http. Browsers don’t like when web pages do that sort of thing, so they don’t let the graph load. A couple things you can do:

1. If you visit the dashboard using http it works since it is consistent with the iframe: http://grx.noc.ucdavis.edu/maddash-webui/details.cgi?uri=/maddash/grids/UCD+Ping+Delay/augury-v4.noc.ucdavis.edu/fumee-v4.noc.ucdavis.edu/Ping+Delay

2. You can update the “<measurement_archive>” section of the mesh-config file you are using to build the dashboard and change the read_url in each to use https instead of http. This will eliminate the problem whether coming from http or https.

This isn't a new issue, so not sure if you previously had only visited using http. It’s a side-effect of how maddash includes the graphs.

Thanks,

Andy

Hi all,

 

We have a small maddash grid, which has been working for a long time, but recently it fails to display any graphs.

 

https://grx.noc.ucdavis.edu/maddash-webui/

 

When I hover over the main page, I saw data displayed, but I click on any square, I got error message of “Error retrieving data, An unknown error occurred”.  I just wonder if my old maddash configuration setting was obsolete, do I need to change the configuration to newer format?

 

Thank you.
