Currently server just discards information obtained from CDP, LLDP, etc. if it cannot find matching node. I think we can store raw topology data for the nodes as well, and show it in separate view (indicating which of IP/MAC addresses are known nodes of course). I've added it as feature request: https://track.radensolutions.com/issue/NX-2277.

Are other parameters related to MySQL working? If so, please set debug level on agent with mysql subagent to 7, try to request one of problematic parameters (or wait few minutes so server did it), and share agent log.

You should be able to use internal parameters ICMP.PacketLoss and ICMP.ResponseTime.Last. Usually you'll need variants without instance - they will return data for primary IP address. Variants with instance should be used when you have configured additional ping targets on a node and want to get information for those targets.

I think that it could be good idea to ignore notPresent interfaces by default on the server level. We will discuss that internally and likely add as configurable option. But for now hook script is a way to go.

Currently only via API - but it should be relatively easy nxshell script or Java app.

When interface is down, we have two contradicting requirements: one is to show what was connected to that interface before it went down, and other is to show actual connectivity. First requires to keep showing link between disconnected interfaces, second requires to delete that link immediately after interface goes down. As NetXMS server has no way of knowing if disconnect is permanent or temporary, and there are seems to be more requests to provide access to last known connection information, NetXMS server keeps that connection until it will know that topology was changed (for example, one of previously connected interfaces will go up and LLDP will report different peer).
One possible solution could be configurable topology expiration time - i.e. if interface is down for N days, remove any known topology information from it.
Currently as a workaround you can delete interface that is disconnected - configuration poll will find it and re-create, but peer information will be erased.

Collector is there, but we didn't get to actually processing flow data. I still want to add this functionality, it is question of available resources and priorities.

From what you show it looks like mail relay successfully received mail from netxmsd, so if you didn;t receive it it was either not sent by relay, or rejected/dropped by receiving server. Do you have any logs from relay regarding forwarding of this mail?

Hi,

do you mean database lock in the DB so server complains that database is locked by another instance? If yes, you should list peer IP address in netxmsd.conf on cluster nodes. For example, if you have cluster nodes with addresses 10.0.0.1 and 10.0.0.2 (with whatever VIP moving between them), on node 10.0.0.1 you should add

PeerNode = 10.0.0.2

to netxmsd.conf and on node 10.0.0.2 add

PeerNode = 10.0.0.1

That way server will read the lock, check if server is running on peer node (by attempting to connect to agent and check running processes and by connecting to port 4701), and remove stalled lock if netxmsd is not running on peer node.

Hi,

it's a bug, just fixed it. Fix will be included into next patch release.

I can confirm that changing server is not implemented yet in new web UI.
