NetXMS Support Forum

Finally! Thank you! works fine now

And yes the $ instead of % was a typo above
I mostly had it working before but was unaware you needed to actually run 'instance discovery' after a config poll. Some of my old scripts magically started working

I'm reviving this thread because i've completely scrapped Windows as a host and gone to Ubuntu - various crashes and other such. Ignore the past few posts as they don't apply anymore. What is important is the title of this thread

I STILL can't work out how to get DCI's for interfaces added automatically because information isn't contained in a simple "here follow this from start to finish" manner, its "google it and work it out for yourself"

Can you let me know if i'm on the right track here and help me fill in the blanks...


1) Create a Template item
2) Right click the new template, choose properties, go to the 'Automatic Apply Rules' section
3) Fill in some sort of matching criteria, this alone is difficult enough to find, but for testing purposes it seems "return true;" will match everything
3a) In my case i'm using "return $node->driver == "UBNT";" to match Ubiquiti devices
4) Click ok, right click the Template and choose 'Data Collection Configuration' then create a new parameter
5) Fill in....
Description: "IN - {instance-name} (bytes/sec)"
Parameter: .1.3.6.1.2.1.2.2.1.10.{instance} (In this case this correlates to the inbound bytes counter of Ubiquiti devices)
Origin: SNMP
Data Type: Unsigned Integer
6) In the Instance Discovery section, choose 'SNMP Walk - OIDs'
7) Set Base SNMP OID as .1.3.6.1.2.1.2.2.1.2 (This should be the interface name/description value?)
8 ) In the script field type in "return $(true, $1, $2);"
9) Now whenever you do a Poll->Configuration (and this happens automatically when adding a new device) the template items should get added to anything that matches the template and each DCI

My understanding is that $1 effectively becomes {instance} and $2 becomes {instance-name}
However while this gets added to the node's as a DCI, those aren't replaced. The parameter still reads .1.3.6.1.2.1.2.2.1.10.{instance} and of course no data is collected
Can someone explain what i'm doing wrong and actually tell me the steps necessary instead of just asking me to go look on the forums. Have already done that...

I've had NetXMS core crash on me once so far and it won't restart because the database is locked, this requires running "C:\NetXMS\bin\nxdbmgr.exe check" but that requires manually answering yes and then later confirming to save changes

Is there a parameter to automate this, so it automatically force unlocks the database and commits changes. That way I can write a simple .bat script to run and check if netXMS is not running and do the above
Because we don't use netXMS constantly we can't really afford for it to crash and nobody is aware for several hours (or days if its a weekend) and we lose a huge amount of logging during that period. Hence the need for an automated script to get it up and running again as quickly as possible

That would have been an old config I tried. The server has both 32 and 64 bit JAVA installed
The current one is pointing to the 64 bit java jvm.dll and it doesn't work, same message as above
I tried uninstalling and reinstalling both 32 and 64 bit versions of Java, Tried manually adding
jvm = "C:\Program Files\Java\jre1.8.0_112\bin\server\jvm.dll" to nxagentd.cfg under [JAVA] and same problem

Still getting

2012 R2 Standard - build 9600

Utterly baffled............................

I added the JAVA_HOME to my PC (which isn't the main NetXMS server) and hey presto java subagent loads just fine
However I just CANNOT get the damn thing to work on the main server. It throws the above error message. My PC runs Java 8 update 92, so I installed the same version on the server, updated the JAVA_HOME path to point to using that version - doesn't work
Tried a bunch of things including installing the standalone NetXMS agent on the server (64 bit). No difference
Deleted and copied the Java and NetXMS Agent folders across to the server so the files are identical. No difference
Gave full read/write permission to everyone on both folders just in case it was something silly like that. No difference

It just doesn't work

The %PATH% variable contains this
C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

JAVA_HOME doesn't exist on any machine, so perhaps its not included in latest versions of Java?
Anyway I created it and entered C:\Program Files\Java\jre1.8.0_101
(Using both 32bit and 64bit java and 64bit agent)

Log file now shows

Is anyone able to fire up a fresh windows VM, install the latest version (2.0.6) of netxms agent and confirm it does indeed load java correctly?
Not sure if its a problem with the latest version of java or some netxms component. It's just not working for me, I get the same error messages as above

I think there's something wrong with the java.nsm file
I turned logging on and had no errors, however I then set debuglevel = 4 and get this

And nope java does not appear in agent subagent list

I also tried starting the agent on a fresh computer and it has the same problems in the log file (fresh install, all i've done is edit the config file to include subagent = java.nsm, and added debug/logging commands)

1) Example for dynamic interface monitoring by instance discovery:
https://www.netxms.org/forum/configuration/interface-names-in-instance-discovery/msg18102/#msg18102

2) Java SubAgent and all its plugins are included with the NetXMS agent.
You just need to install Java yourself, and set the appropriate configs (as per the wiki).
Then you will see the Agent Parameters as in the screenshots on the wiki, and you can create DCIs to monitor what you need on the UBNTs.

I had the agent installed automatically with the server binaries package. c:\netxms\ubntlw.jar wasn't there. The only file was netxms-agent.jar and 2 folders (ndd, sql)
I installed the agent on another computer, this included netxms-agent.jar and ubntlw.jar so I copied the ubntlw.jar file over
Modified c:\netxms\etc\nxagentd.conf to this

LogFile = {syslog}
MasterServers = 127.0.0.1
FileStore = C:\NetXMS\var
RequireAuthentication = yes
SharedSecret = **REMOVED**
SubAgent = winperf.nsm
SubAgent = portcheck.nsm
SubAgent = java.nsm

[JAVA]
Plugin = C:\NetXMS\lib\ubntlw.jar

[ubiquiti-ap]
10.255.5.1 = **REMOVED**

[ubiquiti-client]


Restarted the NetXMS agent. Opened management console and did poll->configuration and then poll->status on the netxms agent.
I open up DCI for the Ubiquiti AP. Add a new parameter, choose NetXMS Agent as the origin type, set source node as the NetXMS agent, click on 'Select...' and there's no Ubiquiti entries in there at all

Update: Answer to #3 was provided by an older post I found on this forum (lost the link to it now.... closed the tab earlier)
It just so happens they were also trying to poll a HP switch. And apparently HP switches won't necessarily respond on the same IP they were polled at, and netXMS wasn't acknowledging the return packets as the source IP was different to where it sent. The answer was to look at the IP address table and I found the switch had an IP on the same subnet as the Agent (I was trying to poll x.254.254), changed it to x.11.254 and hey presto it worked perfectly fine

We're a managed services company and have decided to use NetXMS as our network monitoring software. I'm still in the early stages of deployment and getting to understand how NetXMS works
Something i'm a bit confused on is in regards to network discovery and agents
We typically don't have a VPN into a clients network and so we can't ever get direct access to their subnet from our network (and we have a lot of clients that use the same subnet range)

We want to install an Agent in their network, and have that agent do all the polling and network discovery of their internal network. So that we don't have to manually add every device 1 by 1

What I don't understand is firstly..

1) How does NetXMS perform its network discovery? In Configuration -> Network Discovery I enter IP ranges. Are these ranges ONLY scanned by the server that NetXMS server is install on? Or does the server tell all the agents "Hey can you please scan for these configured IP ranges and report back to me"
If it's the former, then how do I get an agent to do active discovery?
If its the latter, is it possible to restrict the scope for each agent. Since I know that most clients only have a single class C network so it would be a huge waste of time scanning 172.16.0.0/12. I would want to tell each agent to only scan on its relevant subnets

2) I believe at this point in time, Agents are polled by the server and not the other way around, correct? So we have to port-forward on the client/Agent's side
Ideally I would like to be able to install an agent in their network, tell it our IP address and it will send to us. So that we don't have to port-forward on every clients network. Is this possible?

3) How do I add devices and have the remote agent be the one that does all the polling. I'm trying to poll a HP switch with a remote agent and its just not working. What exactly do I have to do
What I've done is 'Create Node' -> Set IP address to that of the HP Switch, set 'Proxy for SNMP' to the remote agent and clicked ok. Is this it? Do I need to do anything else? Cause its not working. This is what I get

Remote agent has port 4700 forwarded, but not 161. Does the master server send all commands to the agent on port 4700 or do I also have to open up 161 (or other ports?)

Also while i'm at it (And I realise this is a different topic)
We have Ubiquiti devices to manage. This page here https://wiki.netxms.org/wiki/Ubiquiti_and_Ligowave_wireless_monitoring mentions an addon which works with the java plugin. But with no download link? Where do I get it?
Nor does it mention how to add the things I want to monitor. It shows pictures but not where to set it up

I'm still new to NetXMS and just trying to wrap my head around it. I don't even know where to go to find auto-bind scripts. The only templates I have installed are really basic ones that it comes installed with. And i've set up some for the equipment we use

Are you able to point me to more specific area's to look at to get my head around this? I.e. which wiki links specifically
Once it clicks i'll be fine, but i'm still trying to get to that stage. And for the moment i'd like to start adding a whole bunch of devices just to get some interface traffic logged. Not practical to add 2,000 devices and have to go and add interface stats individually

If I can get a how-to on just that, or some links to the topics to narrow my focus I should be fine from then on to fine tune

I've seen this mentioned in the manual under Instance Discovery
NetXMS can create parameters for Data Collection Item automatically

But with no mention of how to do it. So.... how do I have it so all interfaces are automatically added for monitoring. And perhaps additional intelligence so it knows if it's a MikroTik to add the MikroTik templates etc
Even better, can it try multiple templates and then automatically remove all the ones that are unsupported?
