perfSONAR User Q&A and Other Discussion

Hi Victor,

Aaron, another question - is it possible to get rid of deleted test results (or any results)? I understand this option  wasn’t included deliberately but maybe you have some script that cleaning some particular data in the database? 

As far as I know, that’s not possible. Unfortunately, the guy who could definitively answer that question is on vacation right now. I’ll have him get back to you when he gets back though.

There is a script to remove the data.  By default a cron script that runs that deletes data based on a set of filters in a config file. Attached is a config file that will delete all data older than 1 week. You can modify it by changing the "expire" property to a value other than 7 (values are in days). To use it, you'll have to run some commands to initialize your python environment then execute the remove script giving it the attached file. The commands are as follows (assuming you downloaded ps_remove.conf to your home directory):

cd /opt/esmond

source /opt/rh/python27/enable

. bin/activate

python ./util/ps_remove_data.py -c ~/ps_remove.conf

Hope that helps,

Andy

Subject: Re: [perfsonar-user] non-standard OWAMP control port

Hey Victor,

Can you try manually editing /opt/perfsonar_ps/regular_testing/etc/regular_testing.conf, and change the “address” fields in the owamp test to take the form: “[address]:888”, and then restart the regular_testing daemon, and then see if it starts working? That’s not changed, so I’m surprised it ever worked.

Cheers,

Aaron

Hi, 

Sorry if somebody has already risen this but I just discovered that toolkit 3.4 doesn’t support non-standard OWAMP control ports and always uses the default value  861 even when some other port was specified in Add New Host  pane.  It can be seen in different ways: 

-  tcpdump shows that owamp requests go out with 861 instead of 888 in my case; 

- regular_testing.log has repeating OWPControlOpen(apus.carnet.hr): Couldn't open 'control' connection to server: Connection refused

- regular_testing.conf has no information about a OWAMP control port value at all. 

What’s more the web page of Add New Host allows to enter a non-standard OWAMP port value only initially but doesn’t have  afield for a port when I open it for editing the Test member parameters. 

At the same time owping –c 10 apus.carnet.hr:888 works without any problems, showing plausible data for both directions. 

I believe that after installation toolkit 3.4 didn’t have this problem, it appeared very recently, maybe last week (probably after some auto update?). 

Does anybody else use a non-standard owamp control port? 

Best, 

Victor
