Nagios Support Forum

Hi,

Good day to you.

I am having an issue whereby I am not able to add several DR servers to my primary Nagios XI.
We have checked on all the firewall rules and it is set to allowed already.
We are able to ping from primary NXI to Secondary NXI successfully which has pass through ASA but there is no reply from Secondary NXI.
Attached are one of the Primary CBJ server which also could not be added to Primary NXI even though other servers with the same range can be added.

Conclusion:

1) Not able to add some DR servers (192.168.200.xx) to Primary NXI server (192.168.100.xx)
- We able to add one server which on the same segmentation (192.168.200.xx) to Primary NXI successfully and have checked Firewall rules
which are set to allow for that segmentation but not able to add other similar servers

2) Able to ping from primary NXI to Secondary NXI successfully which has pass through ASA but there is no reply from Secondary NXI.

3) Attached one Primary CBJ server which also could not be added to Primary NXI even though other servers with the same range can be added.



Please do advise if you need more information on this issue.

Hello @phaandiyan2412

Thanks for reaching out, appears that you have made all the necessary adjustments to the firewall but no response. Sounds like this could be a permissions issue and was want to find out what you see in the Windows Event logs for messages related?

Here is a support article that outlines wmic user permissions, and this one provides additional information on things to verify:

Please provide the results on what you find so we can provide further assistance on this.

Thanks,
Perry

Hi,

We have checked from the server perspective as well and there is no permission issue from the server side.
All looks good. There is no information either on Windows Event log of any issues.

Hello @phaandiyan2412

Thanks for following up, let's take a look at XPUT curl command to see what it is telling us when adding the 'host'.

Example:
You can example here:

• Help > Config Reference > API - Config Reference --Hosts --- PUT config/hot/<hostname>

Please follow up with the results,
Perry

Hi,

I have ran the command and pasted the attachment here for your reference.
Please take a look and advise.

The script as below:

curl -XPUT --verbose "http://192.168.100.xx/nagiosxi/api/v1/c ... lyconfig=1"

I tried adding back but I still having the same issue.

PS: I can telnet (135) to the DR servers from NXI without any issues so It is not related to Firewall.
There is no permission issue as well from the server side.
