perfSONAR User Q&A and Other Discussion

["Lixin Liu" <>]

Hi Shawn,

 

I am not sure what this really means. The example given in both 3.4rc2

and 3.3.2 are the same.

 

I wonder this is because host sask1pfs2.canarie.ca is set to do both

bandwidth and latency tests:

 

  <host>

    description    CANARIE Saskatoon

    address        sask1pfs2.canarie.ca

 

    <measurement_archive>

      type        traceroute

      read_url    http://sask1pfs2.canarie.ca:8086/perfSONAR_PS/services/tracerouteMA

      write_url   http://sask1pfs2.canarie.ca:8086/perfSONAR_PS/services/tracerouteCollector

    </measurement_archive>

 

    <measurement_archive>

      type        perfsonarbuoy/bwctl

     read_url    http://sask1pfs2.canarie.ca:8085/perfSONAR_PS/services/pSB

      write_url   sask1pfs2.canarie.ca:8570

    </measurement_archive>

 

    <measurement_archive>

      type        perfsonarbuoy/owamp

      read_url    http://sask1pfs2.canarie.ca:8085/perfSONAR_PS/services/pSB

      write_url   sask1pfs2.canarie.ca:8569

    </measurement_archive>

 

    <measurement_archive>

      type       pinger

      read_url   http://sask1pfs2.canarie.ca:8075/perfSONAR_PS/services/pinger/ma

      # No 'write_url' for PingER measurement archives

    </measurement_archive>

  </host>

 

so same read_url appears twice (perfsonarbuoy/bwctl and perfsonarbuoy/owamp).

We did not have any problem with 3.3.2.

 

Thanks,

 

Lixin.

Hi  Lixin,

 

If you  haven't  done it yet, you must  update  the  MA  urls  used  in  your  mesh  config to  use  the  new Esmond  URL.    

 

All  the  read  and  write  MA URLs for this  host  in  the  mesh config should  be  updated  to  look  like:

 

http://ndt-sfu.westgrid.ca/esmond/perfsonar/archive/

Hi,

I upgraded a perfSONAR test VM from 3.3.2 to 3.4rc2 and start
getting Mesh Errors from the daily cron job.

I have no problem with 3.3.2. This host (ndt-sfu.westgrid.ca)
is a VM for installation test only.

Here is the section for mesh-config:

<mesh>
    configuration_url
https://ps-dashboard.computecanada.ca/mesh-config/ComputeCanada-tests.json
    validate_certificate        0
</mesh>

<mesh>
    configuration_url
https://ps-dashboard.computecanada.ca/mesh-config/westgrid-tests.json
    validate_certificate        0
</mesh>

Thanks,

Lixin.
