Greetings, Ivan,

Thank you  for reply.

Please see attached screen shot of our toolkit GUI page. The services still have “Not Running” status.

Our ntp package is above 4.1

# yum list ntp

Loaded plugins: fastestmirror, product-id, refresh-packagekit, rhnplugin,

              : search-disabled-repos, security, subscription-manager

ntpdate        0:off 1:off 2:on 3:on 4:on 5:on 6:off

Please advise. 

Thanks!

Hi Rong,

 

It appears to me that the picture on your toolkit GUI page must have changed ever since your previous report.

Please update us on the status.

 

Please verify and report the version of the ntp daemon: yum list ntp. It should be > 4.1

 

Regards,

Ivan

Greetings, Ivan,

 

Thank you for your reply. I and my colleague had trouble shooting for a while. 

 

After I restarted the three services, I did restart several times, the following messages are associated the most recent restart:

( seems no error )

 

 

Regarding NTP,  our server currently synchronize with institutional time servers, I do not use external time servers.

As the current documentation : http://docs.perfsonar.net/install_centos.html Step3

command /usr/lib/perfsonar/scripts/system_environment/enable_ntpd appears to be outdate? No such script?

 

Regarding our server, it’s a RHEL 6 box.  We have due network interfaces on it in order to reach by two network systems.

Not sure if this makes perfSONAR confuse at some point.

eth0

• Speed:1000M
• ipv4 addresses:10.113.113.62
• MAC address:3C:A8:2A:14:72:50
• mtu:1500

eth2

• Speed:1000M
• ipv4 addresses:10.113.117.13   
• MAC address:3C:A8:2A:14:72:52
• mtu:9000

 

I appreciate very much for your input!

 

Rong

Subject: RE: perfS0NAR Services not running

 

Hi Rong,

 

The web_admin.log is a very high level log for the web interface of the toolkit.

In order to give us a better picture of the current case, could you please restart:

-          sudo service bwctl-server restart

-          sudo service owamp-server restart

-          sudo service cassandra restart

 

and  provide us the messages from the commands above and excerpts of a little while before the restart from:

-          /var/log/messages

-          /var/log/perfsonar/owamp_bwctl.log

-          /var/log/esmond/esmond.log

-          /var/log/cassandra/cassandra.log

 

Please tell how did you get to this state? Is that a new install or an upgrade? What in your understanding led to this state of the toolkit?

 

Please note the above commands are not sufficient to restore the full operation of the toolkit.

 

Regards,

Ivan

Greetings, 

 

Services bwctl, regular_test, owamp and esmond in the perfSONAR shown on web interface are “Not Running”.  Please see the attached screen shot.

I looked at web_admin.log and saw those error messages:

I do see those values are defined in the /etc/bwctl-server/bwctl-server.conf

# bwctl control channel

peer_port       6001-6200

# bwctl measurement test ports

test_port       5001-5900

Can anyone please advise what’s wrong here? 

Thanks,

Rong
