Do not know actualy... Maybe

1)  3 x BGP-4 Router
2)  minimum 15 RadioBriges of 155 MBit to 1 GBit
3)  unknown number Repeaters
4)  many managed Switches

Because the network is a redunant Backbone Network, I think 
PING is not enough. Need control of all important functions.

Realy often for security reason.

I know and curently I am making some test with my NETBuilder II 
and two ATM Repeaters and my Workstations/Servers.

I have seen there is 'postgresql' support ;-)
I think, I will install it. 
But does it support snmp ?

Thats right, but I need only Marocco, with a 
little bit Algeria, Mauretania and then Spain.

I have coded a smal tool with a Landmap of this. 
I case of an error, my Application open a new 
"Error" Window which is zoomed into the "Error-Zone"

There is nothing which works not with snmp, exept some of my HUB's 
which need an seperatly snmp-Module. Same for my UPS-Systems. 

I think, they must controlled too.

This is why I ask in this List. Most of you are longer in this 
business then me and I am using Linux (Debian) since 03/1999 
(it was SLINK r2).

I will check it out.

I think, I need to install it. but on a seperated Workstation 
of which I have enough ;-)

Question:	If I install nagios-pgsql, does 'nagios' 
		configure my postgresql alone ?

I think, I need to try out all two.
