perfSONAR User Q&A and Other Discussion

[Daniel Manzo <>]

Hi all,

 

My current perfSONAR setup is an HP server with 8 GB of RAM and an OS of RHEL 6.8. I installed using the CentOS bundle method with perfsonar-toolkit. After installing MaDDash 2.0 from the staging repo, I realized that perfsonar-graphs updated to 4.0, which is not compatible with the version of perfsonar-toolkit I have (3.5.1). I used yum to remove MaDDash and the staging repo, but I have not been able to see the graphs on the web interface. It just shows a red bar with “Error loading test listing: Internal Server Error”. I have been getting the same three errors in regulartesting.log for a while and have not been able to fix them:

 

2016/10/16 01:00:41 (8232) ERROR> EsmondBase.pm:53 perfSONAR_PS::RegularTesting::MeasurementArchives::EsmondBase::__ANON__ - Error writing metadata (500) 500 Internal Server Error

I have tried the following steps to fix the problem:

rm –rf /var/lib/pgsql/data/*

/usr/lib/perfsonar/scripts/system_environment/configure_esmond

/usr/lib/perfsonar/scripts/system_environment/configure_regulartesting

/etc/init.d/httpd restart

/etc/init.d/perfsonar-regulartesting restart

cd /usr/lib/esmond

source /opt/rh/python27/enable

/opt/rh/python27/root/usr/bin/virtualenv --prompt="(esmond)" .

. bin/activate

python esmond/manage.py migrate

 

Maybe there is something else that I need to remove that was leftover from MaDDash 2.0 that is affecting the database/test results? Any advice or tips would be very helpful.

 

Thanks,
