perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <zwlu@ucdavis.edu>]

Hi Chris,

 

I doubled the “cellSize”, “cellPadding”, and “tetBlockSize” from their respective default values in this file:

/opt/maddash/maddash-webui/etc/config.json

 

Since I have a small mesh, this makes the visual a little better.

 

I have restarted the regular testing server a few time already, but when I click on any square (green or orange/green), I don’t get any graph.

 

Thanks.

Hey nice grid, how did you get the squares to be that large?  Mine are really tiny.

 

As for the orange squares, it looks like your tests are working, what I would do is go to Settings, Server Settings and schedule a refresh.  You need to set an admin user before you can do that.  The steps are listed here for creating the admin user -

I did what you suggested and it worked.  Now I change the subject a bit.  My maddash setup using the mesh configured hosts, I didn’t get anything in the “Graph”.  If I get to individual perfsonar web page, I can get graphs displayed between these hosts.  I also noticed that it appears that the band width tests going only one way rather than having both band width and “reverse” band width tests.

 

Here is my maddash info:

maddash-server-1.2-4.noarch

maddash-1.2-1.noarch

maddash-webui-1.2-3.noarch

 

my maddash page is at:

Thank you very much for your help

Hi,

 

Do you have multiple “host” elements in your mesh that have the IP addresses you list below? If so, you should combine them into 1 ‘host’ object with multiple addresses.

 

Cheers,

Aaron

Hi all,

 

I am setting a local mesh for our perfsonar servers (five in all). I am encountering problem on my last server which happens to have two interfaces and v4/v6 addresses.  I would appreciate suggestion to fix the mesh generation problem here.  I am running:

 

perl-perfSONAR_PS-MeshConfig-Agent-3.4-15.pSPS.noarch

perl-perfSONAR_PS-MeshConfig-Shared-3.4-15.pSPS.noarch

perl-perfSONAR_PS-MeshConfig-JSONBuilder-3.4-15.pSPS.noarch

 

Mesh Error:

  Mesh: UC Davis Mesh

  Host: 

  Error: Multiple 'host' elements associated with the addresses on this machine: melange-v6.noc.ucdavis.edu, melange.noc.ucdavis.edu, 2607:f810:330:1ffd::f, melange-owamp-v4.noc.ucdavis.edu, 128.120.80.78, melange-v4.noc.ucdavis.edu, 2607:f810:330:1ffe:0:0:0:f, melange-owamp-v6.noc.ucdavis.edu, 2607:f810:330:1ffe::f, 128.120.80.74, 2607:f810:330:1ffd:0:0:0:f

 

Thank you.
