Remote Network Monitoring

I need to monitor several servers' for simple connectivity. These servers
on disjoint non-routable networks, each of which is protected by its own ISA
Server firewall.

This is the system I'd like to use: Each network has one machine which
serves as a local monitor. It pings local machines to verify connectivity.
Aside from notifying a remote monitoring station of any failures, it reports
regularly to the monitor. If the monitor fails to receive a regularly
scheduled report or receives a notice of a failed machine on the remote
network, it sounds an alarm.

Does anyone know of any software that can do this?

WhatsUpGold or ServersAlive should be able to do something comparable, if
not entirely identical.

Thanks, Lanwench! I've looked them over and I'm going to try them out.

You're very welcome - good luck.

Hello,

Microsoft ISA also have "connectivity verifier". When it fails, ISA
sends a mail to alert you.

Yes, Nagios certainly is a good tool -- if you've got a Unix or Linux server
to use as a monitor, but all of the machines with which I'm concerned are
Windows-based. It would be fun to play with Nagios, though.

I was actually using ISA Server's connectivity verifiers to monitor some
critical local machines. And using ISA Server's connectivity verifiers
simply isn't appropriate, since they're not intended to monitor other
machines. They're meant to monitor the the ISA Server machine itself. In
addition, denting a firewall by connecting ISA server by VPN to external
networks doesn't seem very smart, and that's what I'd have to do to monitor
a lot of remote machines.

I've been running the free trial version of Servers Alive, and I'm
impressed. After playing with it for an hour or so, it was easy to figure
out how to use it. It's chock full of notification methods. I found it
easy to configure it to periodically connect to remote networks using VPN
connections that I'd set up in Windows networking. While it has a wealth of
capabilities for monitoring various services, the ping test was good enough
for me. Besides, it appears that the tests that require remote agents can
add significantly to the cost of the software. But I'm sure that the tests
that don't require remote agents are good enough for the vast majority of
situations.

Servers Alive offers nothing in the way of reports, but I figure that's
actually a good thing, since they're useful mostly for the people who would
be looking over my shoulder. It tells me when a machine or node is
unreachable, that's all I need to know. Still, it would be very helpful to
get reports on the frequency of intermittent failures or roundtrip times.

A real boon is the ability to configure tests and machines in a logical tree
structure. I'd like to have more direct control over the testing sequence,
especially since the last test of a machine on a remote network has to
perform the disconnection from that network. But with the small number of
machines I'm using for this demo (32), I've been able to make it work.
Monitoring hundreds of machines over several VPN connections may be a bit
more problematic. Still, it's doing what I need, and I may use it.

I'll set up WhatsUp Gold on another machine in a couple of days, and I'll
report back then.

Hi.

i'm running nagios on a 200 usd f10 headless box, and is monitoring :

w2k3 sbs server via snmp + performance counters + ip tools
lan printers
mysql services ( not servers )
gateway
+ whatever you can think of.

try nagios. its addictive.

pleite
