perfSONAR User Q&A and Other Discussion

[Brian Candler <>]

One of my perfsonar nodes has upgraded itself to 3.5. The graphical 
interface is pretty but I'd like to report the following things which no 
longer work.

(I can send the actual server links off-list to developers; these are 
non-public servers)

Many of the breakages relate to IPv6.

The "tests result" section still shows two rows, one for v4 and one for v6:

cov-client-1.snipped    cov-perf-1.snipped
X.X.X.X                 Y.Y.Y.Y
Details | Traceroute

cov-client-1.snipped    cov-perf-1.snipped
XXXX:XXXX:XXXX:XXXX     YYYY:YYYY:YYYY:YYYY
Details

Problem 1: clicking on either of the two "Details" links shows the same 
graph. The graph headers say

         Source                       Destination
cov-client-1.snipped              cov-perf-1.snipped
X.X.X.X, XXXX:XXXX:XXXX:XXXX Y.Y.Y.Y,YYYY:YYYY:YYYY:YYYY

Previously, I could get different graphs for the v4 and v6. Now I can 
only get one, and it's not even clear which it's showing.

Clicking "link to this chart" gives a URL which contains
graphWidget.cgi?source=cov-client-1.snipped&dest=cov-perf-1.snipped

whereas before it would have given either the IPv4 or IPv6 addresses.

(2) From the time of the upgrade, I get red dots showing:

"04:57:41 10/01/2015
Error from bwctl/traceroute:
Problem parsing traceroute output: Can't find hop number in output: 
traceroute6 to XXXX:XXXX:0:2::254 (XXXX:XXXX:0:2::254) from 
XXXX:XXXX:1:64::252, 64 hops max, 12 byte packets at 
/usr/share/perl5/vendor_perl/Net/Traceroute.pm line 624.
04:57:41 10/01/2015"

This might also explain why there is no "traceroute" link in the "test 
results" section for the IPv6 addresses.

(3) From the time of the upgrade, ping tests have stopped working (the 
dotted yellow line for "reverse ping" has just stopped)

But Configuration > Tests still shows the section (which I called "Local 
ping test"), and I can see the test is still there.

(4) Probably unrelated, but click on services directory and it takes you to
http://stats.es.net/ServicesDirectory/
there's almost nothing (just a few red dots in Asia)

Brian.
