Checking node services

How I can check service is up in a node? I've looked for a MIB that shows which ports are open, but only I find the connections that are in use.
Thank you

Re: Checking node services

I guess my first question is whether you are attempting to see if the node is up, or if connectivity is up, or if a particular service is active.

These are all different tests, but many could be used to provide the same answers. For instance if you check a Server for inetd running, it's obvious that you'll be able to telnet to the machine (as long as the telnet daemon is enabled).

The other question to as is should I be using NNM or ITO? NNM is a great Network Monitoring tool, whereas ITO is exceptional for Server Monitoring.

As the old saying goes, there are many ways to skin a cat, the tools that you select to perform that skinning can make you job either easy or difficult. If you have ITO, I would recommend using it to check for various services. But you can perform similar tests on the Server and report them back to NNM using SNMP.

Hope that helps.

Re: Checking node services

Hi Albert,
I'm sorry, I've a NNM 6.01 and I want check if a particular service in a sever node is active. The MIB's that I've found show the active connections but no the open ports in the server. I would like to do a collection of this service and when the service down to force an event.

Thank you

Re: Checking node services

CTsar,

What is the Service?

What type of Node?

Is there a listener which launches the services (i.e. portmapper, inetd ....)

I cannot be more specific with out more information.

Also, I would like you to consider the possibility that it would seriously reduce the network overhead (especially if you have many machines to monitor), if this monitoring was performed on the server locally.

Re: Checking node services

Albert,
I'm sorry twice.
I want monitor ports 25,80,110(SMTP,POP3 and HTTP)of four NTServers and five Linux Slackware7.
Thank you again
