Distributed monitoring without direct networkconnection

[Nick Lunt]

Hi Ton

 

thanks for the info.

 

It's not that the connections will be up/down it's more that they simply
won't be there. Most of our clients are NHS (hospitals) and we  have to
have a secure vpn connection that we dial into on an as needed basis.

We currently just send alerts as emails to our support account, but the
company is getting bigger and bigger so monitoring the support inbox is
becoming a massive chore. We really want a central nagios server with
the web frontend on a big flat screen on the wall :)

 

Im setting up a filter in postfix on the central nagios server so that
all emails coming in will go thru the filter, the filter will run a
script to call send_nsca.

 

So I'll have nagios clients -> nagios  -> send_email -> primary nagios
server -> postfix -> mail filter -> send_nsca -> nagios

If I get this working I'll treat myself to curry :)

Thanks for the plug, but Opsview is not really suitable for this. We
have distributed monitoring out-of-the-box, but it requires the
permanent connection between slaves and the master which Nick says he
hasn't got.

 

If you will have temporary connections (that go up and down), we have
been thinking whether we can do "batched results from slaves", though
this is quite a big job as it requires changes to a lot of components
(Nagios, NSCA, NDOutils, and our datawarehouse). Let us know if you
fancy sponsoring this work.

 

Otherwise, why can't you just have notifications from the other servers?
Do you need to correlate with your central server?

 

Ton
