Scott,
Could you send your PMR number and I will try and attach my call to it?
Cheers,
jane

I do not get service icons on the node.
I have opened a PMR. We waited for this feature and now that it's here, it's not usable and there is nothing in the docs to indicate it shouldn't work.

Hi Scott,
We were having this debate only last week. I don't know the answers but
I've inserted my guesses below. Anyone else know?
BTW - do you get the service objects for your servmon services showing
at the interface level of a node? I can't make this work on my AIX 5.1
system. From reading the docs, I thought this was now supposed to work
on Unix platforms as well as Win.
Cheers,
Jane

NetView v7.1.4 / Solaris 2.8
Greetings. There is a new enhancement / replacement for nvsniffer
that I am having trouble getting to work. The concept is to detect
whether a particular TCP port is accepting connections and report an
event if it is not. It looks to me like servmon will now do this.
nvsniffer as I recall will discover but not monitor port level
applications.
The problem is this:
The servmon configuration requires that you specify what port the
application runs on and what smartset contains the nodes that are
considered "targets" for the servmon application.
I have a smartset created that has 3 Unix servers.
Each of the Unix servers has multiple instances of the software
running on multiple different ports.
You can put multiple ports in the servmon port field if you wanted a
collection of everything running app XYZ
Each of the Unix servers is multi-homed (4 physical and 12 virtual
addresses).
My guess here is that it uses the Selection Name of the devices and
tests against whatever the DNS gives him as it's IP address - be
interesting to know the real answer to this one...
Each instance of the software is tied to a virtual address.
What does your DNS do with these virtual addresses????
Each instance of the software uses one or more ports.
I doubt that servmon can tell you how many instances of the software are
running - just whether there IS an instance running. Only way I can
think of tackling this is to use discovery and status custom plugin
modules to run scripts that do what you want. The issue is how you
"talk" to each system as the scripts actually run on the NetView
server. I've wondered about using rsh/ssh/rexec to do this but not
actually tried yet....
In my configuraiton, I specify I am interested on port 26001 (for
instance).
Since the boxes are multi-homed, I don't think servmon can tell which
interface/IP address to probe for port 26001 activitiy
The creation of the smarset means that the nodes listed are the right
boxes, but not the right interfaces for activity on those ports.
SO my question is - is servmon smart enough to figure out the traffic
is NOT on the interface that is resolved in DNS and thus located in my
smartset? Since servmon actually adds a field in ovwdb (field name
drivin by servmon.conf) I cannot specify an interface in the servmon
config or the smartset - only a node name since it doesn't appear to
add a field to an interface object, only to a node object.
