[root@psLT-USP: perfsonar] /etc/init.d/perfsonarbuoy_owp_master restart
Sent HUP to 2889
perfSONAR-BUOY OWAMP Measurement Service restarted

Before I do the restart, my .log had showed:

Sep  9 12:10:39 ps-lt owampd[2900]: FILE=sapi.c, LINE=303, Connection to ([143.107.6.19]:861) from ([143.107.6.19]:47983)

After, the .log is like the first e-mail I sent you:

Hey Luis,

Can you try doing “service perfsonarbuoy_owp_master restart”, and see if it spits any errors out?

Cheers,

Aaron

Hey Luis,

Does /var/lib/mysql/mysql.sock exist?

Cheers,

I checked if the service is running and it is running normally. Could be other thing?

Thanks.

Hi Luis,

Can you check your MySQL server is running?  And if not restart it.  That can be done with:

sudo service mysqld status
sudo service mysqld restart

If MySQL doesn't start, there'll probably be more information in the /var/log/messages file.

Cheers,

Antoine.

Hi, everyone!

When I acess the Graphs Services, all my tests appear inactive :(

In the .log the messages appear, but I don't know what they means:

How can I repair this?

Thanks.
