Distributed Infrastructure Setup

[danjoh]

Hi, I'm new to Nagios and this Board, so please do not be to harsh

Today we have a setup like this

Code: Select all

            Firewall
               //
+--------+     //     +--------+       +-----------------+
| Nagios |     //     | Nagios |       |     Client-1    |
| Master | <--NSCA--- | Slave  |------>| "active" checks |
| (NSCA) |     //     |        |       |                 |
+--------+     //     +--------+       +-----------------+
               //

(with more than one "Slave")

What we now want to implement is something like this

Code: Select all

            Firewall
               //
+--------+     //     +--------+       +-----------------+
| Nagios |     //     | Nagios |       |     Client-1    |
| Master | <--NSCA--- | Slave  |------>| "active" checks |
| (NSCA) |     //     | (NRDP) |       |                 |
+--------+     //     +--------+       +-----------------+
               //         ^
                          |
                          |            +-----------------+
                          |            |     Client-2    |
                          +----NRDP----| passive checks  |
                                       |    send_nrdp    |
                                       +-----------------+

(No, we do not want the "NRDP-client" to talk directly to the "Master).

Is a setup like this possible?

At first glance this should work, but it will depend on how specifically you are sending things via NRDP to the slave, and via NSCA to the master. How exactly are you sending that data over? OCSP commands, event handlers, notifications, or something else?

[danjoh]

We are using ocsp_sweeper to send the data from the Slave to the Master.

TNX for you Feedback.

OCSP is probably going to work here, but I am not familiar with the ocsp_sweeper tool so I can't speak to its effectiveness.

[danjoh]

OK, TNX for your feedback. I'll have a try next week.

Let us know how it goes. Thanks!

Everything looks great.
Service status is show and gets correctly updated (including "missing" data) and the performance-graphs gets correctly displayed.

I only had two major issues while setting this up.
1) Truncated performance data "delivered" to PNP4Nagios (has really nothing to do with this thread).
2) Some send_nrdp.sh issues (syntax errors in the script and some issues when running it from cron).

Once again, TNX

Glad to hear it! I'll close this up now, but if you need anything in the future please don't hesitate to ask!
