Hi,
I got a message on one of my computers that there were more than 500 events
in the last 10 mins. At the same time a user complained that the computer
had had a dramatic slow down. When I went and had a look, I couldn't find
anything. So I changed the threshold for the evmlogger to 0. But I still
can't find a simple solution, that will allow me to look at the events in a
simple order. I guess I'm missing utilities like uerf or dia that just allow
you to look at events in reverse order, and the show you the time without a
lot of fuss.
I have got a number of different versions running, the oldest is 4.0D and it
goes up to 5.1A. A common factor to some of my slow down problems seems to
be a DS10 running 5.1A that has a kzpcc-ce 3 channel raid controller and
2x4314 disk towers. Up until this week things seemed to have been humming
along, then around mid week, people started to complain about slow downs. I
inspected the disk arrays, and there was no indication that there were any
problems with any of the disks. By the way I have failed to get SMOR client
running on my PC. The agent seems to be running on the DS10. But when I try
to start the client up, I get a message from the DS10 to say the connection
was refused??
Another thing that seems to be common, is the fact that a connection is
being made between an UltraSparc10 (running Solaris 2.7) and the DS10. All
nfs type mounts are controlled by automount on the DS10 and vfstab file on
the Sun. Connections between the DS10 and the UltraSparc seem to be
unbelievably slow at the moment, even when there is very little traffic
around, ie about 8:00 at night. The files are being copied from the Sparc to
the DS10, first the DS10 was mounting one of the Sparc disks, now I have
changed it to the other way around. I have also set one of the mount options
to tcp.
We don't have control over the routers and switches in this place so I have
no way of finding out if packets are being dropped. I can only assume that
something has happend besides maybe a little bit more traffic, but I don't
know what.
