RE: [nv-l] nvsniffer / servmon

["Barr, Scott" <Scott_Barr@csgsystems.com>]

Well, I'm still digging!

 

It appears that discovery works. The config file says the second field in the config is the "service smartset" and describes it as the "smartset to create if the service is discovered" to exist. My smartset IS being populated and when I right clikc -> monitor -> network ->services - the ports show up. The only thing that does not appear to be working is the creation of the service icon as part of the node. Here is my config if anyone wants to take a stab at whether it's "right"

 

isCICS_Gateway|5000,5503,7000,7020,7050,7051|CICS_Services|CICS_Gateway_Service|||Production_OS390|5

 

The address of the nodes listed in the "Production_OS390" smartset are all multi-homed with the services actually responding on the real interface, not the SNMP address which is the virtual.

I'm not the expert on this, partly because it is so new, and partly because I don't work with it.  But I don't think the first version of servmon is as flexible as you might like it to be.  According to my understanding, in the case of raw port tests, it appears that only the SNMP address is tested.  The raw port test does not test all IP addresses on a node.

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.
Each of the Unix  servers is multi-homed (4 physical and 12 virtual  addresses).
Each instance of the  software is tied to a virtual address.
Each instance of the  software uses one or more ports.
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.
