perfSONAR User Q&A and Other Discussion

Hi,

After making that change you need to wait for the maddash checks to run again. Looks like they have had a chance to do so and seem to be working for me this morning.

Thanks,

Andy

Hi Andy,

I have modified the file /etc/maddash/maddash-server/maddash.yaml 

from

maUrl: 

        default: "http://%row/esmond/perfsonar/archive"

to

maUrl:

        default: "https://%row/esmond/perfsonar/archive"

After I restarted maddash-server, the maUrl didn't change immediately to https on my browsers. On my test maxtrix,  some shows with https, but other stay at http, is it a browser cache side effect?

I am testing it from my home now, it appears that https for maUrl is shown on my browser.

I am having a tough time to force

http://maddash-server/maddash-webui to

https://maddash-server/maddash-webui

using mod_rewrite in 

 /usr/lib/maddash/maddash-webui/.htacess

or in /etc/httpd/conf.d/apache-maddash.conf

RewriteCond %{HTTPS} !=on

RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]

maddash is actually served by a java application, is that right?

Please enlight me how I can achieve that task.  

http://maddash-server/maddash-webui works with https in maUrl in the graphs, though.

Thanks again.

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.
