Too many alerts

[millerpaint]

Greetings,

Just upgraded to v1.2.3.1 - so far, so good! My question: When the gateway router goes down for any given subnet on our WAN, I receive "node down" alerts for each device within that subnet (servers, printers, etc.).  Of course, those nodes are not really down, just temporarily unreachable. In this situation, all I really need (and want) to know is that the gateway router is down, and that is all.  And then of course, a second alert when the router comes back up.

What is the easiest way to accomplish this?

Thanks,

Theoretically, server should do that automatically if it knows route from itself to nodes behind router. However, it often not working as expected. You can also do manual correlation using situations.

Greetings,

I believe I see the problem: Our NetXMS server does not see the remote router on our MPLS network when doing a traceroute to a node behind that remote router.  I will inquire with our network provider about this, as I would much rather have the server do this, rather than having to configure a situation for each remote subnet.

Hi Victor,

I spoke with our network provider; they do not believe that the remote router being "hidden" from a traceroute would have any impact on the NetXMS server knowing the route to the remote devices.

You mentioned that it it often does not work as expected - is this a known bug?

Hi Victor,

Has this issue been fixed with v1.2.4?  If not, could you provide me with the bug #, so I can track it.

Thanks!

OK great, thanks Victor!

I am now monitoring 50 remote networks, and so far I am happy with NetXMS (and I have yet to upgrade to the latest 1.2.4 version)!
