perfSONAR User Q&A and Other Discussion

[Jon Clausen <>]

Hi

We have the same issue on our CentOS7 pS 4.0.1 measurement archive:

'Ping' latency graphs are not shown with 'report range' shorter than one
week.

Looking at the patches at
https://github.com/perfsonar/graphs/commit/eb560cca62634fc587be297769a8cf3d17bcb1fd
and comparing with the files on the system, there are pretty big
differences (the sections of code are at different line numbers) but it's
clear that the 'bundle.js' (for example) has not been 'patched':

[jac@psma01 ~]$ grep WEIRD /usr/lib/perfsonar/graphs/html/public/bundle.js
                                //console.log("WEIRD: multiple summary
                                //windows found. This should not happen.",
                                //win);

The file;
[jac@psma01 ~]$ rpm -qf /usr/lib/perfsonar/graphs/html/public/bundle.js
perfsonar-graphs-4.0.1-1.el7.centos.noarch
[jac@psma01 ~]$ ls -l /usr/lib/perfsonar/graphs/html/public/bundle.js
-rw-r--r--. 1 perfsonar perfsonar 6045058 Aug 11 17:23
/usr/lib/perfsonar/graphs/html/public/bundle.js

The package was updated 2017-08-06;
[jac@psma01 ~]$ sudo grep perfsonar-graphs /var/log/yum.log
May 17 12:26:38 Installed: perfsonar-graphs-4.0.0.2-1.el7.centos.noarch
Aug 16 08:00:01 Updated: perfsonar-graphs.noarch 4.0.1-1.el7.centos

And currently there are no updates available;
[jac@psma01 ~]$ sudo yum update

 * updates: mirror.nsc.liu.se
No packages marked for update

Have the patches simply not been applied to the rpms, or am I
misunderstanding something?
