NetXMS Support Forum

Okay, thanks for that info.  I can see from https://wiki.netxms.org/wiki/NXSL:Node that isRouter is a node attribute, but isSTP is not...  I put that in based on what I saw in the below image.  I see most of those things are available attributes, but not isSTP.  I'll have to try another approach.

I can probably accomplish what I need to do for the moment based on the driver or sysDescription attributes, but for future reference, can I pull SNMP values from the newly discovered node like this and use it to filter them?  https://wiki.netxms.org/wiki/Script_Example:_Read_SNMP_Value_From_Node

Good evening,

I have noticed these two operators which aren't in the documentation and would like some clarification on their use.

One of them is a single dot.  Based on usage, it appears to be used to concatenate strings?  From the Wiki page Script Example: Read SNMP Value From Node:

value = SNMPGetValue(transport, ".1.3.6.1.2.1.1.1.0");
if (value == null)
{
    println "Failed to issue SNMP GET request";
    return 2;
}
else
{
    println "System description: " . value; // This dot
    return 0;
}

The other one is this which I've seen in a number of places, including the built-in scripts: ->  Example from Filter::AgentOrSNMP:

return $1->isAgent || $1->isSNMP;

I can see that it's referencing the capabilities of the node, but when I try to do this, the script fails, and NetXMS logs an event with description "error 15 in line 5: uknown object's attribute."  On this one, I'm trying to filter out some printers and a few other devices with SNMP that I don't want it to discover.  What I was going for on the line causing the error is return true for a device that has SNMP, and also is either running spanning-tree or is a router.  Maybe there's a better way to do this.  It's my first attempt.

As best I can figure, $1->isSNMP returns true if the discovered node $1 has that capability, but I couldn't find this -> operator in the documentation.

// Select any device running the NetXMS agent,
// or any node with SNMP that matches criteria.

if ($1->isAgent) {exit 1;}
if ($1->isSNMP && ($1->isSTP || $1->isRouter)) {exit 1;}
exit 0;

Thanks

Okay, I got it working, but it seems a bit strange.  What I did was I switched to openjdk-8-jre (from jessie-backports) and tomcat8. 

When I go to ipaddress:8080/nxmc, I get an odd error from Firefox about the page redirecting in a way that will never complete.  I suspect it's redirecting to /nxmc.  So just for kicks, I went to ipaddress:8080/nxmc/nxmc, and it actually works.  I guess that'll do.  I hope this info is useful to someone.

I fixed the issue with the Windows management console.  I didn't realize it was going to be all Java.  I downloaded the 64-bit version, but I only have 32-bit Java installed.  I downloaded the 32-bit console and was able to log into NetXMS.  Seems the server is up and ready to go.

I would really like to get the web management console working if we can figure that out.

Also, I mistakenly said I was using Firefox Quantum.  I'm actually using Firefox ESR 52.6.0 32-bit which was why I had 32-bit Java.

Some related logs.  Directory listing of tomcat7/webapps and dpkg --get-selections attached.

2018.01.25 14:33:54.497 *I* NetXMS Server started

I'm new to NetXMS (coming from Opsview and Zabbix) so please excuse me if I've made a rookie mistake.  A little background... I'm trying to run NetXMS 2.2.2 on Turnkey Core 14.2 (Debian Jessie).  I have installed tomcat7, tomcat7-admin, default-jre (openjdk-7-jre), postgresql (postgresql-9.4), netxms-server, netxms-dbdrv-pgsql.  I have set everything up according to NetXMS Administrator Guide, and as far as I can tell, the NetXMS server is up and running.  However, I can't get the Windows or web management consoles to work.

My preference is to use the web console, so I tried that first.  I renamed nxmc-2.2.2.war to nxmc.war and put it in /var/lib/tomcat7/webapps.  It seems to deploy, but I get a 404 error when I try to open ipaddress:8080/nxmc.  Error attached below.  I have also tried deploying it with the tomcat web manager and had the same result.  The tomcat web manager says nxmc is deployed and running.  I am using Firefox Quantum for this.  I also tried it in Edge, but all it says is "Hmmm...can't reach this page."  Very helpful...

On this release, I can alternatively install openjdk-8-jre, postgresql-9.6, and tomcat8.  I tried that briefly but still seemed to have the same problem.  I did also try this briefly on Ubuntu Server LTS 16.04.3 but again had the same problem with the web console.

Now, I have also tried the Windows x64 management console on Windows 10.  I extracted the nxmc folder to Program Files and ran nxmc.exe.  It churns for a couple seconds and then gives me the below error.  Not sure where to go with that either.

Any help is much appreciated...
