Inter-server communication

Hi!

I have a problem sending events to another NetXMS server.
Both servers are version 1.2.10, ISCListener enabled, ReceiveForwardedEvents enabled, port 4702 opened, Events matched and nodes matched. (one server is in remote location)
Debug says that, event was failed to forward because of Invalid or incompatible NXCP version.

So how can I match the versions?

Thanks in advance,
Nikk

Hi!

Actually looks like a bug. I'll check it a bit later.

Hi,

Any news to this?

Hi!

I cannot reproduce this problem. Just build test setup with two servers and they are able to forward events. Can you please provide appropriate parts from logs of both servers running at debug level 6? Also, what is exact versions and platforms for those two servers?

Best regards,
Victor

Hi,

Sorry for late respond, was abroad.

So debug 6 on sender server

On the receiver server i don't get anything related to this.

Sender server:
Linux ubuntu-server 3.5.0-45-generic #68~precise1-Ubuntu SMP i686     
NetXMS server - 1.2.11

Receiver server:
Hardware: Intel64 Family 6 Model 45 Stepping 7 AT/AT COMPATIBLE - Software: Windows Version 6.2 (Build 9200 Multiprocessor Free)
NetXMS server - 1.2.11

Hi,

I managed to get rid of the previous error, but now i'm getting another:

On Remote_Server:

[12-Mar-2014 14:10:40.651] [DEBUG] EVENT 17 (ID:1822 F:0x0001 S:1 TAG:"") FROM Remote_Server: Threshold reached for data collection item "Inbound traffic on enp10s1 (packets/sec)" (Parameter: Net.Interface.PacketsIn(2); Threshold value: 10; Actual value: 11)

And on Local_server

[12-Mar-2014 14:10:41.386] [DEBUG] ISC<Remote_Server>: session closed

But in reverse situation (local -> remote) everything worked fine!
Then i have a question, what is this object which cannot be found?

On both servers ISCListener enabled and ReceiveForwardedEvents enabled.
On both servers there is identical (except ID) node object with the same ip address.

Local_Server - 1.2.12,  Ubuntu 12.04 LTS
Remote_Server - 1.2.10, Ubuntu 12.04 LTS

Hi!

Are you using zones on Local_server? Currently receiving server looks for IP address only in default zone.

Best regards,
Victor

Hi,

Yes, zones are being used.

Hi,

So, is this bug or it isn't implemented yet? Maybe there is another way how to send events to local server?
The thing is, that our main devices are located in remote areas, but monitoring should be local. And Proxy-agent connections just occupy the network.

Respectfully,
Nikk
