perfSONAR User Q&A and Other Discussion

[Andy Lake <>]

Hi,

You may just need to wait some time. After you reboot BWCTL may not start right away as it waits for NTP to converge. This is expected behavior. Within an hour or so bwctld should start on its own. After that it may take several hours for your tests to collect its first data. If you still don't have any data this morning, can you share /var/log/perfsonar/owamp_bwctl.log?

Thanks,

Andy

Thanks Andy,

I have setup the Perfsonar toolkit again. May be there were some problem in previous installation. Now both of the testing tools running. I have test OWAMP, its working. But I am facing problem with BWCTL test.  I have scheduled for BWCTL test but it is not showing any data in "Service Graphs -> Throughput" page. Could please help me with this problem.

For your understanding,

I have observed that after rebooting the system " Bandwidth Test Controller (BWCTL)" is not running. I refreshed the browser several times but still was not running. Then I ran it using the command:  /etc/init.d/ service bwctld start . After running this command its shows followings:


[root@dhcp39-88 init.d]# service bwctld start
/usr/bin/bwctld -c /etc/bwctld -R /var/run
bwctld[2671]: FILE=tools.c, LINE=319, Compiled-in tools: iperf nuttcp iperf3
bwctld[2671]: FILE=iperf.c, LINE=80, IperfAvailable(): iperf_cmd unset, using "iperf"
bwctld[2671]: FILE=nuttcp.c, LINE=81, NuttcpAvailable(): nuttcp_cmd unset, using "nuttcp"
bwctld[2671]: FILE=tools.c, LINE=339, Available tools: iperf nuttcp iperf3
/etc/init.d/bwctld start: bwctld started
[root@dhcp39-88 init.d]#

Do you see any problem in the above output?

Please help me to solve this problem.

Thanks

Hi,

Thank you. I am not sure how your owmesh file got in the state where its missing parameters like the DataDir. Can you try running the following to reset your owmesh file?

rm /opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf

  yum reinstall perl-perfSONAR_PS-perfSONARBUOY-config

        /opt/perfsonar_ps/toolkit/scripts/upgrade/upgrade_owmesh_traceroute.sh

        chmod o+r /opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf

        reboot

After the host reboots add back your tests via the GUI. That should hopefully get things back to a normal state. 

Thanks,

Andy

Yes, I am scheduling tests using GUI on toolkit ( https://.../toolkit/admin/regular_testing/). I have also run bwctl by hand as follows,

As I have mentioned one version of owmesh.conf file is after scheduling bwctl test and another one before scheduling the test.




Thanks

Hi,

How are you configuring your tests? Are you using the regular testing GUI on the toolkit or are you doing things by hand?  Also, why are there two versions of your owmesh file?

Thanks,

Andy

Hi,

My perfsonar still is not running perfSONAR-BUOY Regular Testing (Throughput and One-way Latency).

 Please help me to solve the problem.

Hi,

Can you send /opt/perfsonar_ps/perfsonarbuoy_ma/etc/owmesh.conf?
