perfSONAR User Q&A and Other Discussion

[Raul Lopes <>]

Hi,

 I have a couple of nodes in a 20 nodes mesh that run the tests, but do not report to Maddash.
 
  The logs are full of lines like
 
  Jul  5 19:19:25 ps03-em1 journal: runner INFO     489461: Posted result to https://ps03-lat.rl.ac.uk/pscheduler/tasks/0203bb86-10af-4d77-a607-a51de117f9cf/runs/defa4e86-a17
  7-41a5-aebc-e1256683bd07
 
  I can use pscheduler on the command line and get latency and bandwidth run with success. However, they do not send anything to Maddash. There is nothing going from that host to the Maddash server.

I have been through the logs.

In particular the bit about esmond logs

If your measurement archive is not running or your graphs are not returning data

Esmond mostly stuff like

2021-04-23 13:48:39,121 [INFO] /usr/lib/esmond/esmond/cassandra.py: Connected to ['localhost:9160']

2021-04-23 13:48:39,680 [INFO] /usr/lib/esmond/esmond/cassandra.py: Checking/creating column families

2021-04-23 13:48:39,682 [INFO] /usr/lib/esmond/esmond/cassandra.py: Schema check done

However also shows

2021-07-06 09:58:14,944 [INFO] /usr/lib/python3.6/site-packages/pycassa/logging/pool_logger.py: Connection 139755773060824 (localhost:9160) in pool 139755772886656 failed:

esmond/django.log has an error

Has anyone seen a situation like that?
