perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Just to reiterate, it would be much better to understand what triggered your digging through the old logs. Upgrading will result in certain services still being installed but not running on your host. Reinstalling seems like overkill since so far the errors shared fall into the category of "nothing to be concerned about". If there is a problem such as a service on the main page is listed as not running or the graphs are not loading, etc that would be good to know about and we can help direct you to the right information to debug.

Thanks,

Andy

It sounds like that host has a strange mix of perfSONAR 3.3 and perfSONAR 3.4 software on it.

Any chance you could wipe the disk and start over with a fresh 3.4 install?

Good afternoon,

Now having started the PingER service, its logs seem full of error:

What is this Key it's wanting, whence should it be got?

Also yesterday these services were started in the order that rc3.d would
start them (in a little "for" loop)
traceroute_ma
traceroute_master
traceroute_ondemand_mp
traceroute_scheduler

No obvious errors at that time: (lost output for traceroute_ma startup)
on traceroute_master
chkconfig traceroute_master on
service traceroute_master start
/opt/perfsonar_ps/traceroute_ma/bin/traceroute_master.pl --config=/opt/perfsonar_ps/traceroute_ma/etc/traceroute-master.conf --pidfile=/var/run/traceroute-master.pid --logger=/opt/perfsonar_ps/traceroute_ma/etc/traceroute-master_logger.conf --user=perfsonar --group=perfsonar
/etc/init.d/traceroute_master start: Traceroute Master started

on traceroute_ondemand_mp
chkconfig traceroute_ondemand_mp on
service traceroute_ondemand_mp start
/opt/perfsonar_ps/traceroute_ma/bin/daemon.pl --config=/opt/perfsonar_ps/traceroute_ma/etc/ondemand_mp-daemon.conf --pidfile=traceroute_ondemand_mp.pid --piddir=/var/run --logger=/opt/perfsonar_ps/traceroute_ma/etc/ondemand_mp-daemon_logger.conf --user=perfsonar --group=perfsonar
/etc/init.d/traceroute_ondemand_mp start: perfSONAR Traceroute On-Demand MP Service started

on traceroute_scheduler
chkconfig traceroute_scheduler on
service traceroute_scheduler start
/opt/perfsonar_ps/traceroute_ma/bin/traceroute_scheduler.pl --owmesh=/opt/perfsonar_ps/traceroute_ma/etc --pidfile=/var/run/traceroute-scheduler.pid --logger=/opt/perfsonar_ps/traceroute_ma/etc/traceroute-scheduler_logger.conf --user=perfsonar --group=perfsonar
/etc/init.d/traceroute_scheduler start: Traceroute Scheduler started

but the logs are full of errors:

root@lcgnetmon> tail -5 /var/log/perfsonar/traceroute_ondemand_mp.log

But, our working Bandwidth box is logging exactly the same so all that noise
must be "normal noise"?! (SIGH, wish for _real_ info/data in logs?!)

Also from yesterday startup, errors in logs:

in traceroute_ma.log

(note that mysql started right AFTER that, according to the order in rc3.d)

Again, our working Bandwidth box is logging exactly the same so all that noise
must be "normal errors"?! (SIGH, wish for _real_ info/data in logs?!)

in traceroute_scheduler.log:

Next to start is regular_testing & hope it doesn't implode again....
