[mrtg] Re: monitoring Windows NT/2000 servers

[Jerry Heidtke]

Another thing that I looked at a while ago is the built-in support in MRTG
for graphing whether an interface is up or down.

Check out the reference on ifAdminHack & ifOperHack.

Here's a sample config that gives you percentage up or down. You might need
to play with the options to get it working right.

--------------------------------------------------------------------
MaxBytes[_]: 100
Unscaled[_]: ymwd
Suppress[_]: 
Options[_]: growright, gauge, withzeroes, unknaszero, nopercent
YTics[_]: 10
ShortLegend[_]: % Up
YLegend[_]: Percent Uptime
LegendI[_]: Admin. Status
LegendO[_]: Oper. Status
Legend1[_]: Admin. Status is Up
Legend2[_]: Oper. Status is Up

Target[server01_UP]: ifAdminHack.1&ifOperHack.1:community at server01*100
Title[server01_UP]: Up Time Statistics for server
PageTop[server01_UP]: <H1>Up Time Statistics for server</H1>

Target[server02_UP]: ifAdminHack.1&ifOperHack.1:community at server02*100
Title[server02_UP]: Up Time Statistics for server02
PageTop[server02_UP]: <H1>Up Time Statistics for server02</H1>

etc....

Yeah, I thought about that graphing thing.  I guess the graphs aren't really
important.  The amount of uptime is important, however.  It is an objective
for our department by management to have accurate uptime/downtime numbers.
A graph would either be ON (up) or OFF (down) I suppose, so over time it
would be mostly up hopefully.  But I was thinking if you installed SNMP on
the server that it would be able to report the actual uptime like the
router's do with MRTG.  We have some software currently that can do this,
but it won't let us do automated HTML graphs that we can post online.

Thanks for the tip on Big Brother.  I was actually in the middle of reading
about their product.  Our ISP recommended it as well since they use it.

Sounds more like you want a tool to tell you if the server is up (i.e.,
available).  Do you care what the actual up time is?  If you are graphing
uptime, it would (theoretically) just continually rise- there is no upper
limit (well, at least if it is a Novell or Unix/Linux box :-) ) and only
return to zero upon reboot (a sawtooth waveform!)

Sounds like you want Big Brother (http://bb4.com) which runs fine on Red
Hat...

Big Brother will also allow you to monitor various services that your
Windows box may be providing (i.e., POP3, SMTP, HTTP, etc.) and let you know
if they are up and page you if they are not.

There are also 3rd party scripts you can add to Big Brother that allows it
to work with MRTG, so various statistics can be graphed also.

Just a thought...

Subject: [mrtg] monitoring Windows NT/2000 servers


Ok, I know there is lots of information out there on this subject, but it
all seems to be based (or at least the stuff I'm finding) on using the
Windows version of MRTG.  I currently have MRTG running great on my Red Hat
7.3 box and it is monitoring our Cisco router.

What I'd like to do, is play with the Windows NT/2000 SNMP service and
monitor these servers FROM my Linux MRTG, not from a Windows MRTG.  I don't
necessarily care to use the third-party SNMP4NT and SNMP42K stuff.  I also
don't necessarily care to monitor CPU utilization or most of the other
performance counters.  What I do want to monitor and graph with MRTG is
simply the uptime of a server.  I might want to add the other stuff later,
but for now I just want uptime.  Basically, if I can ping it, it is up.
That's as simple as I want to begin with.

So, are there any web pages out there that describe how to set this up that
you have seen?  Any other tips for me?

Thanks a lot,
Allen
