I haven't yet gotten the gumption to check in the middle of the night to see
how the processes are playing out on the servers. I suppose I could be lazy
and cron out a couple of amstatus reports during the night, but I'd be more
content actually looking at the servers and seeing what's going on. I'll
just have to bite the bullet and wake up. ;-)
Isn't this what amplot is for?
[ sorry if the following is a bit like stream of consciousness . . . ]
I've never used amplot.
OK. So, I checked the man page for amplot and also for gnuplot. The
issue, and the reason I have never used it, is that I have minimally
installed server OSes. That is to say, when I install Solaris 10, I
start with the minimal + network. Then I add only those packages I
want/need. So, *no* graphical interfaces of any kind. Rack mounted
servers with serial consoles. No video cards. I don't think I even
installed the X11 libraries, which would end up with another long string
of dependencies. My Solaris 10 installs take a fraction of the space of
an "end user" install, which is less than a "programmer" or "everything
+ kitchen sink (OEM)" install.
I think that means that even if I tried to export the display to my
desktop computer running X11, I wouldn't have the facilities on the
server to generate it.
Can amplot generate old fashioned ascii graphics?
Or, could I grab the amdump.1 data file and plot it from my desktop? Of
course, then I would have to install Amanda on my desktop (Mac OS X
10.5.8), but I've been meaning to do that anyway.
OK. Thinking out loud and moving along. I did a `amplot -p -l amdump.1`
from the logs directory and got a postscript file. Transferred that to
my desktop and opened it in preview, which translated it to pdf. I think
it worked. Interesting. Not completely what I'm after. It gives some
perspective, but I'm still left guessing about particular servers. It
looks like most of the dumps finished by the end of the first hour. One
server must have taken about 3 hours to complete, and the last server
with the largest dumps took a few more hours after that. Network
bandwidth and holding disk are no problem at all.
I think I still want to look at actual processes on servers and see
what's up.
Or, has amplot changed significantly in recent releases? Might it have
options for individual servers (Amanda clients)?
I suppose reading amdump.1 directly is an option as well.
hmm. That's nuts. It's over 13000 lines of chatter. Some interesting
pieces in it, but hard to assemble a picture.
It's Friday. I can sleep in Saturday morning. I'll jsut get up around
1:00am and have a look see around the servers. Check loads. Check
amstatus. See what's running on each one. & so on.
