perfSONAR User Q&A and Other Discussion

[Soichi Hayashi <>]

Jason,

I have following in the /opt/perfsonar_ps/perfsonarbuoy_ma/etc

(perfsonar-bw)

> BWDataDir       /usr/local/perfsonar/perfsonarbuoy_ma/bwctl

(perfsonar-lt)

> OWPDataDir      /usr/local/perfsonar/perfsonarbuoy_ma/owamp

These re-configuration were needed to prevent perfsonar from running out of disk on the default /var partition.

The config creates pid file in following location (for perfsonar-bw)

> /usr/local/perfsonar/perfsonarbuoy_ma/bwctl/bwmaster.pid

which contains a correct PID

2013-09-27 19:11:47 UTC [root@perfsonar-bw:/usr/local/perfsonar/perfsonarbuoy_ma/bwctl]# cat bwmaster.pid
1850
2013-09-27 19:11:50 UTC [root@perfsonar-bw:/usr/local/perfsonar/perfsonarbuoy_ma/bwctl]# ps - grep 1850
497       1850     1 99 17:44 ?        01:27:31 /opt/perfsonar_ps/perfsonarbuoy_ma/bin/bwmaster.pl:master

I am guessing that.. web interface is using the default pid location to look for the PID file, and incorrectly determining that the process are not running? 

Thanks!

Hi Soichi;

The local services page is designed to look for PID files and process names for the various services.  In the case of Latency testing:

> my $pSB_owamp_master_pid        = "/var/lib/perfsonar/perfsonarbuoy_ma/owamp/powmaster.pid";
> my $pSB_owamp_master_pname      = "powmaster";
> my $pSB_owamp_collector_pid     = "/var/lib/perfsonar/perfsonarbuoy_ma/owamp/upload/powcollector.pid";
> my $pSB_owamp_collector_pname   = "powcollector";

And in the case of Bandwidth testing:

> my $pSB_bwctl_master_pid    = "/var/lib/perfsonar/perfsonarbuoy_ma/bwctl/bwmaster.pid";
> my $pSB_bwctl_master_pname      = "bwmaster";
> my $pSB_bwctl_collector_pid     = "/var/lib/perfsonar/perfsonarbuoy_ma/bwctl/upload/bwcollector.pid";
> my $pSB_bwctl_collector_pname   = "bwcollector";

The check will go into 'not running' if there are no PID files, or the PID in the file doesn't match the process name that is currently running.  That would be the first place to look (and naturally the old fashioned 'reboot' has been known to fix this).

With regards to your Bandwidth test machine - I don't see any tests in an active state via the results page, so that may be additional troubleshooting you will want to do.

Thanks;
