Nagios and Hobbit are a naive solution for very small operations. They can be a very
small part of what operations want, but any installation wanting to manage multiple
servers has more complete z/VM and Linux requirements. Tools based on simple availability
and CP Indicates don't meet any knowledgable set of requirements. And tools created for
the distributed system are always disabled by any installation that care about perforamnce.
Installation that bother to test and measure those agents quickly turn them off. If you
only have a very few servers, the overhead doesn't matter, installations with more servers
usually care more about performance... We (Velocity Software) work very hard on our
agent - our agent uses '.1%' (point 1 percent) of one processor per Linux server, with one
minute data collection, we can successfully meet the requirements of Operations,
Performance Analysis, Chargeback and Accounting, as well as Capacity Planning. And this
is down to the Linux application and process level. The alerts feed into any SNMP
management console, 3270 or web display (or email if they want).
So I would suggest looking at how many virtual servers you think you will have and match
an infrastructure that will work. Talk to references that know what works (or doesn't).
It's too bad when only consultants and vendors answer questions asking "what others are
doing" since they don't do it.

Nagios or Hobbit are quite nice for that sort of thing, or just use the
same tools you use for the distributed systems. If you don't have such
tools, that's a nice thing to offer the rest of the organization as
(another) reason for the Linux on Z distribution.

Subject: Process or tool to verify linux/oracle environment under vm
We are looking to implement a tool or develop a process for use by the
Operations staff to use to check the availablilty of our linux guests
running under vm. When we IPL vm, the vm guests all start, however
sometimes, linux and/or Oracle database running under linux donot
correctly complete initialization. We need an operator friendly tool or
process to verify linux and oracle availablility at IPL time, whenever a
linux guest is recycled, or any other time operations deems necessary.
We are trying to find out what others are using.
Thanks, Bob
