Re: Monitoring NT Services
I've found monitoring NT over SNMP to be extremely unreliable, but it's possible. This is what I did for NT4.0, it may be different for win2k: Check out this 'http://www.techie.net.nz/networking/mrtg/' site (which has changed drastically since I last used it). Basically, you need to install the perf SNMP extension on each monitored host, either get find it online on the NT resource kit cd. If it is already included in win2k this will be much easier. Then find a copy of mbrowse for linux, I think it is on sourceforge.net. Install the windows perf extension MIB on your linux box and fire up mbrowse. Browse for the values you are interested in. There's probably a canned SNMP monitor for mon, but I am testing with a shell script that uses the ucd-snmp's 'snmpget' and 'snmpwalk'. All of these can be obtained free online, though the perf SNMP extension is Microsoft property and may have a license.

Unfortunately, I have little experience with Mon or with network management/monitoring. Has anyone found a way to monitor NT services reliably? I've considered using SNMP; however, I haven't found any way to use SNMP to check the status of a running service. I've considered using SNMP traps; however, this doesn't seem terribly reliable since the UDP packet could never make it to the server running Mon. Using traps tells me something bad happened but it doesn't give me the sense of security that actually checking the services periodically would give me. Has anyone else in the Mon community found a way to solve this problem? If possible I'd like to implement something that doesn't require installing software (particularly commercial software) on all of my NT boxes. Any suggestions, experiences, best practices, things to avoid, etc. would be greatly appreciated. Thanks, Jason Winters

Sorry for late notice, I will be attending perl mongers meeting today (Dec 09). I live in the area, and use mon extensively to monitor systems at work.

Re: WINDOWS-NT-PERFORMANCE MIB for snmpdiskspace.monitor
Check this out: 'http://www.geocities.com/Area51/Rampart/9209/' It has a link a zip, perfm.zip, that has all you need and a nice batch file to install it.

RE: SNMP
Scott and William,, I agree, snmp on NT is a pain. Often many values are empty, or tables are incomplete. The snmp service also crashes often enough I have to use a batch loop to keep it running. Many services can be tested in other ways, though. You can directly connect to mail servers via shell or expect, scan for listening ports to determine applications that are alive, and use the samba suite to test file and print services. Performance data is hit-or-miss, you can get it using snmp on some boxes and not others. Check out this site for more about snmp on NT if you do decide to use it: http://www.geocities.com/Area51/Rampart/9209/ Brian Fender "Scott Prater" <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 11/04/02 04:24 AM To: <[EMAIL PROTECTED]> cc: Subject: RE: SNMP A caveat: we've had horrible experience with the Microsoft perfmib and snmp service. Some problems we've encountered: -- If an interface on a card changes to a down state, the instance variable simply disappears. -- CPU, memory, disk space: the values never get refreshed after the first snmp query. Microsoft recommends stopping and starting the snmp service every five minutes as a programmed task in order to force a refresh. In short, forget the Microsoft snmp service. You'll be much happier installing an snmp service from either the machine vendor (Compaq and Dell both have snmp services), or some third-party software, such as Net-SNMP for Windows. Or, just reformat the hard drive and install Linux. Scott Prater Dpto. Sistemas [EMAIL PROTECTED] SERVICOM 2000 Av. Primado Reig, 189 entlo. 46020 Valencia - Spain Tel. (+34) 96 332 12 00 Fax.
