NetXMS Support Forum

So I have NetXMS server 4.3.2 running, local client connects, no issue.  The WebUI however is not.  It reports: Server uses incompatible version of communication protocol.

The odd part, I am running 4.3.2 on both the server, local client and WebUI, yet it reports version mismatch.  I even downgraded the WebUI to v4.3.1 and I get the same error, but when I looked more closely at the error, the version doesn't seem to match up?  The error is: Server uses incompatible version of communication protocol.  (server= [60, 4, 1, 1, 1, 43, 1, 2] client= [60, 4, 1, 1, 1, 44, 1, 2]). Neither of these seem to match up with the real version... I am expecting to see 4.3.2 or 4.3.1 for the client, but seeing what I can only suspect is 4.3.1.2 (server) and 4.4.1.2 (client).

Any ideas?

Is there any way to add additional passive rack elements, like a fiber patch panel for example.  Would be great to be able to add these to make the system image resemble the rack as much as possible.

I apologize if this has been answered, I couldn't find it in my searches... but I am having issues with network maps.  When setting the background to the exact same zoom level as is displayed using a GEOLOCATION MAP (by right clicking a container for example) my network map does not look anything like the GEOLOCATION map.  The center of the map is way off the canvas. In fact, my center point cannot even be seen.  Secondly, the map does not fill the entire screen.

Is there a way I can make the network map look as good as the GEOLOCATION map? My desire is to have a map that supports network connection linkage, which the GEO map doesn't support.  I will also note, the world map generates fine as well... just the "Network Maps" section is where I have issues.

I have attached the maps below and you can try it for yourself.  Set the geo container to N40 by W85 with a zoom of 10 and then do the same thing with a network map.
You will see in my comparison, the network zooms far south east versus the geo map which centers correctly.

Am I doing something wrong or just better off using an image based map?

Hello,

I am new to writing scripts for discovery and have that down ok... but I am looking for a way to also filter the interfaces if they are not active.

In this case, I have a sonicwall I wish to monitor, but I don't need to see all the ports not in use.  They all show UP because they use PortShields which connect all the ports in an UP fashion, so I wanted to filter on MTU which in SNMP shows zero on all the ports I wish to ignore.

My SNMP DCI looks like this:

Param: .1.3.6.1.2.1.31.1.1.1.10.{instance}
Discovery (OID): .1.3.6.1.2.1.2.2.1.1

Discovery Filter:
transport = CreateSNMPTransport($node);
if (transport == null)
return false;

// get the interface name to return as instance-name
vb = SNMPGet(transport, ".1.3.6.1.2.1.31.1.1.1.1." . $1);
if (vb == null)
return false;

// filter out loopback
if (vb->value == "lo")
return false;

return %(true, $1, vb->value);

I know MTU is pulled in and stored with the interfaces, but not sure how to filter in the discovery script I have so far.

Like I said, pretty new at this and just getting my hands dirty.... so any help would be greatly appreciated!

I am getting an odd transformation error (that never occurred before, until after the 2.2.1 update).  This is happening on the NetXMS server agent node.

(HOSTNAME xxx.xxx.xxx::227::TransformationScript) execution error: Error 13 in line 1: Cannot do automatic type cast

Unfortunately from this error I am not able to determine which of the several data collection items I have is the culprit.  I am getting results back on all my collection items, no invalid data but still getting the error... thoughts?

Thanks in advance!

I looked around and could not find a post about this... from time to time, I get new network interfaces showing up on machines that are not changing in any way.  I have ruled out multiple ip's, nic's etc.  These literally happen all the time and I think to date all in Win OS environments.  Today for example, I have 3 new Local Area Connections (labeled 9,10 and 11).  The server in question has but a single IP and ipv6 is off.... yet each of the NICS being reported as new show ipv6 addresses.  It shows the interface type as tunnel(x3) and one called Interface Type=6 (ethernetCsmacd) which has an IP which isn't even in this subnet -and- belongs to a different server.  Further, this server does not have any VPN services or any other type of tunnel protocol enabled. 

ipconfig/all shows none of these adapters, mac addresses or anything.  Any thoughts as to why this keeps happening and how to stop it?

Thanks!

I am monitoring services from a windows agent, in a table.  I have a threshold set to look for any service set to auto that is not running.  I have exceptions as well, ignoring Software Protection, Google and other services that start and stop on demand (although set to auto in the service itself).  This works well for the most part, however I am getting false positives on this.  For example:

Threshold reached for data collection item   "SYS - Services" (Parameter: System.Services; Threshold value: 0x00000086; Actual value: 18)

Do I need to break up my conditions or something? How do I narrow down what service it is that hitting the threshold?

Thanks in advance!

I couldn't find this in any documentation or on the boards...
Was wondering if it is possible to trigger an alert if a specific software package version has changed?  For instance if SERVER X has IE 10.1.1400 and it updates, then reads IE 11.0.0000.  Can that trigger an alert?

Thanks in advance!

So, I have battled this issue a lot.  I have never gotten it working and I really need to figure out how.  When I indicate I want the agent to register manually with NetXMS, I fire up the nxagentd with the -r <server>.  Sounds simple enough... so why for the love of all that is holy can't I get this to work?  I have tried -r with the ip and the dns name.  I have tailed my server log and see no activity whatsoever.

If installed the latest version of the agent (also running latest build of the server) and I did see a moment where the agent tried to download a config file from the server (the -M)... so that seemed to work, though i didn't have a valid file there for it... which I would love to do but haven't read up enough on it yet to know... I digress.

So does anyone know any reason the -r wouldn't work.  Like I said, I see no indications that it is even attempting to do it.  Thanks so much in advance!

It seems with the latest build, I am no longer able to query SNMP via an proxy agent/host.  Example:

NETXMS Server ----> AGENT w/ SNMP Proxy---->SNMP Device

Queries directly to an SNMP from the NETXMS server appear to work still....

Anyone else seeing this?

Thanks,

I tried doing this... nada.  The instructions are not totally clear, so no doubt I am doing something wrong, but looking at the JAVA code, it looks like it loads the image file (assumed to be the netxms_login.dat) into a variable and calls if present.  Otherwise the standard logo appears.  Has anyone had any luck doing this?  Are there any other undocumented tips for the WebUI?  Like can you change other features, the title of the app, etc?  Thanks in advance all!

I apologize if I missed this somewhere, but is there an easy way to get NetXMS to wait until two missed pooling cycles pass before considering a node "down".  I have one location that has squirly internet and I get about 30 notifications a day.  I just want to know if the event lasts more than one pass.  This would be the built-in up/down status.  Not on a specific service or rule I have built.  As far as I can tell, it looks like I would need to disable the pooling and look for my own data.

A number of the agent download links are broken.  Unix/Debian 32 bit (netxms-agent_1.2.0_i386.deb) for example is no longer accessible.  Anyone?

I really like this product and hope I can get it to do something other than just the "Status".  I have loaded custom mibs (compiled fine).  I see the item in the tree... when I add any snmp item, it always changes to UNSUPPORTED.  I am not sure what the deal is.  I have tried custom, generic calls.. all the same.  When I check the device config, it connects with snmp fine, pulls the interface names, determines the type (in this case Sonicwall).  Every time it says...

But when I add any OID, I get "Status of DCI:<num> (SNMP: <oid>) Changed to UNSUPPORTED"

What am I missing?  Thanks in advance.
