Run the following on the sending device:
and:
Make sure to replace NRDP_TOKEN with your actual token. The receiving XI appears to be recognizing the nrpd interface on http. If you point your browser to https://monitor.c1.net.au/nrdp/, does the page open?

The commands to directly check from sender were both sitting there doing nothing.

But it did reveal that even though I had put an IP address directly into the sender config, that it was then trying to use a FQDN for the post command, and that it was resolving the external address and not the internal one.

Once I dropped a host entry into the sender and re-ran those http/https checks they immediately came back with success post as below.

Am waiting to see if anything appears in unconfigured objects currently.

That looks correct, may we mark this resolved?

Hi Scott,

As there is still no objects coming through in unconfigured I don't think we can.

All I know is that the sender is correctly comm'ing tot he receiver, but nothing is showing up still.

Do you have a host configured called "somehost"?

I see a "somehost" in the unconfigured objects on the receiving server

However the sending NAgiosXI instance has 120 differnet hosts configured, none with that name.

So are these 120 objects actually working and updating? For instance if the checks were not being scheduled they would not be returning data and hence NRDP would not be sending anything to the other server.

Yes the sending server is online and actively checking.

I've attached a screenshot showing that checks were performed only a few minutes ago.

On the sending server tail the log file with this command:
Do you get any information about outbound checks?

I'm not seeing anything about outboundchecks.

On a hunch I forced a host check as below.
