perfSONAR User Q&A and Other Discussion

[John Hess <>]

hi,

i recently separated our central esmond MA to a distinct physical server, 
ps-ma-lax.cenic.net, from the host (VM) on which our pS MaDDash is running, 
ps-dashboard.cenic.net.   the time-series graphs had been working well — up 
until they stopped working a day or two ago.  

i am tracking perfsonar-staging on both systems w/auto-updates enabled.   the 
dashboard VM has pulled in perfsonar-graphs 4.0.1 v0.1.rc1.el6.   (after 
clearing browser data) within the browser -> Graph pane, the region which 
would otherwise display the graphs now displays this error:

Error loading data
Error retrieving data
Can’t connect to ps-ma-lax.cenic.net:443 (connect: Network is unreachable)

the (Chrome browser) javascript console log has these entries:

dojo.js:15 [Deprecation] Synchronous XMLHttpRequest on the main thread is 
deprecated because of its detrimental effects to the end user's experience.

'https://ps-ma-lax.cenic.net/esmond/perfsonar/archive/?source=ps-svl-10g.cenic.net&destination=melange.noc.ucdavis.edu'
 because it violates the following Content Security Policy directive: 
"default-src 'self' ". Note that 'connect-src' was not explicitly set, so 
'default-src' is used as a fallback.

i did not find a good match for the symptom among the open perfsonar/graphs 
issues on GitHub:

        https://github.com/perfsonar/graphs/issues

though closed issue #85 ‘Add security headers for graphs’ looked interesting.


thanks,
