perfSONAR User Q&A and Other Discussion

[Wilson Cheung <>]

perfSONAR team,

I'll chime in and say that I'm also experiencing the same problems with fresh installs of Ubuntu Server 20.04.6 with latest OS updates plus latest perfSONAR 5.0.4 Toolkit.  I did the "apt install perfsonar-toolkit" option as described at "https://docs.perfsonar.net/install_debian.html".

Nothing ever shows up in the "Test Results" section of the Toolkit webpage.  Have tried on multiple Ubuntu installs on both physical and virtual machine servers with a mix of 1GigE/10GigE NICs.  I'm able to login via the toolkit webpages and add more  tests to run more frequently (e.g. every 15-minutes) to see if anything would show up.

I did a separate full pS 5.0.4 "toolkit" install on a fresh install of CentOS 7.9-2009 plus latest OS updates to compare and results do appear under the "Test Results" page, so this problem may be Ubuntu specific.  Haven't tried other Debian-based distros yet.

On the Toolkit webpage of the Ubuntu servers, it says "pscheduler" is "Running" in green.  If I leave it in this state and don't reboot the servers for a few days, the pscheduler status tends to eventually changes to "Not Running" in red.  If I manually restart all of the pscheduler services, it goes back to "Running".  Still no "Test Results" appear locally.

On the Ubuntu servers, I also see the same errors in the "pscheduler.log "that Ivan listed about "Failed to archive" and "Failed to put result: 503" and "503 Service Unavailable".

I also see other errors in "logstash-plain.log" and "opensearch.log" about Java.  A recent post talked about making sure your servers are not under-resourced and allocating more memory resources to the JVM used by opensearch/logstash.

Before I dig further down into the various pS internals, are there other specific logs or others I should focus on checking?  I'm not sure if there's something pS configuration specific I missed.

Thanks!

I have a fresh install of Ubuntu Server 20.04 and Perfsonar Toolkit but it refuses to show the test results. Can someone help me with the following issue:

Thanks for looking into this Ivan. Something must have gone wrong with my upgrade from Ubuntu 18.04 to 20.04 and/or perfsonar v4 to v5.

 

I just did a clean install of 20.04 on the server followed by perfsonar v5 and all services are running without issue.

Hi all,

 

I am not sure about the problem and the observation of Shayne, but…

I have completed a fresh install of the pS Testpoint 5.0.4 on Ubuntu 20.04 and have seen no issues.

Hi Fedorka,

 

The real problem is actually in this error message:

WARNING  Queue maintainer got exception ModuleNotFoundError: No module named 'pycurl'

 

You are most likely somehow missing this package

python3-pycurl

Hi Ivan,

 

The output of the requested command does not return anything.

 

Yes, the one command did get cut, here is the full output:

Dear Shayne,

 

Indeed this is a strange problem. I am myself running a test pS instance of Ubuntu 20.04.

Please share the output of this command:

sed -e 's/#.*$//' /etc/pscheduler/daemons/ticker.conf

 

Is there some cutting of text from the diagnostic window?

I am not sure this command from your output makes sense:

echo OPTIONS=$opts > /var/run/pschedule

I also have this issue after upgrading from perfsonar version 4 to 5 on Ubuntu 20.04. I found the pscheduler-ticker service is failing but I’m not sure why.

I have this problem as well, but only on my Redhat 9.2 perfsonar boxes, what version OS are you running on this one?

Hi,

   I found an strange status of pscheduler service on Toolkit dashboard, it is showing that service is "Not running" but when I checked the services on server it is showing all the services are running including pscheduler. Any idea that where is the problem? I have attached screenshot.

 

 

 

Thanks
