We also have TMON for zOS and the only thing you can see is the use of the
IFL and LPAR's CPU usage. In our case we are not under zVM yet so each
LPAR correspond to one Linux image.
We also use our in-house developed Linux monitoring facility (same source
of information as sar and acctcom) but in addition they watch applications,
daemons, networks, mount points and all those little things that can break
Service Level Agreements. I am just in the process of getting published in
the CMG (Computer Measurement Group) magazine. I wrote all the daemon
programs and WEB applications (mostly perl) and I can make them freely
available if enough interst is shown. I can also send a copy of the
article to anybody interested off-list.
Please note that we are in the process of getting zVM and we will use zVM
tools as well. There is a balance between what you monitor inside each
Linux image (that zVM cannot see) and outside from zVM or zOS.
We just came back from our D.R. drill and our DF/DSS backups under zOS of
our zLinux worked like a charm. We "init 2" the Linux image before we do
backups of the system volumes using DF/DSS. After backups, we do an "init
3". We are automating this process with UC/4 that does the scheduling for
zOS, Linux and all of our Unix flavors (Sun and AIX) and also our Windows
(w2k and w2k3).
We do weekly backups of all of our Linux application volumes as well.
Today we are using MySQL but soon we will start implementing Oracle. The
Oracle guys might want to use Oracle tools for their backups.

Please respond to
Linux on 390 Port
I am pondering how to go about monitoring the Linux guests here at my shop.
We have ASG's TMON for our z/OS system, but I don't think they have a Linux
product yet. For the moment, I'm thinking about trying some unholy
combination of the VM Performance Toolkit, top, and maybe Nagios or mon.
Nagios, mon, and other such products are capable of producing e-mails to
lists of support personnel. (In our case, we can use an e-mail to trigger
a pager if we want.)
We also have ACF2 on z/OS, but I don't think there are any plans (yet) to
expand that to Linux; it wouldn't surprise me, though, if we eventually
went to some sort of LDAP setup.
We use FDRINSTANT for our backups. We bring the VM/Linux volumes online to
z/OS, shut down the Linux guests, run the snapshots, restart the guests,
run the backups, and then vary the volumes back offline. I have not yet
gotten an opportunity to try a test restore of the backups, though.

Just a couple of quick questions.
Does anyone use any 3rd party tool,like OmegaMon, to monitor zlinux?
Has anyone every tried to implement CA's eTrust ACF2 Security for zLinux?
Has anyone tried doing volume level backups using FDR or DFSMS?
Do companies have a production control area monitoring the monitor? Or do
you page when alerts happen?
Reason for questions. We are trying to build a case for the use of zLinux
in our shop. Management wants to be assured that all the pieces are there
before they will go forward. Thus the fact finding mission.
