Can someone give me an example of a transform script that pulls a value from a DCI table into a variable?

I have upgraded my CentOS system running  V2.0-M4 to  V2.0-M5.

I installed the new web interface .war file and restarted my tomcat service.

However now when I attempt to access the web interface I get a HTTP error 403 page as shown here:
-------------------------------------
HTTP Status 403 -

type Status report

message

description Access to the specified resource has been forbidden.
Apache Tomcat/7.0.62
---------------------------------------

Is this a bug, or did I do something wrong?

Thank you tomaskir, I replaced "FindDCIByName" with "FindDCIByDescription" and that did the trick.

I have been working on a SNMP Free memory % transform script and I have found few examples that I can't get to work and I am not sure what I am doing wrong.

I have created a DCI parameter for total memory for the device, and another DCI for the free % transform as shown here.
memTotalReal, OID parameter - .1.3.6.1.4.1.2021.4.5.0
Memory Free %, OID parameter - .1.3.6.1.4.1.2021.4.6.0


I get the correct value for the Total Memory DCI, and on the second DCI for free % I apply this transform script:

sub main()
{
   total = GetDCIValue($node, FindDCIByName($node, "memTotalReal"));
   
   return $1 / total * 100;
}

However, I only get the value of the DCI SNMP poll as if I didn't do any tranform.  So it does not seem to be returning the correct value.

Can anyone tell me what I am doing wrong?

netxms 2.0M4

How long does this take, I have changed my template several times and it does not change the given DCI values on the nodes that it has been applied to.

Ok, I don't know if this is by design but I think I have found the answer.

I had set many of my nodes to "Ignore" interface state as they have many interfaces that are erroneous.

If you have the interface set in this manner alerting and alarms do not fire.

Here is more information, I am still no closer to understanding why this is happening but here is the return of a "Poll Status" of a known down node.  At the end it says node status normal, yet it should be critical.

I am having issues with nodes not showing the proper status.  I have about 100 nodes being monitored on this system.

The server is Version 2.0-M4, on CentOS.

If I disconnect network to some of my nodes their status never changes, however if I disconnect it from other nodes the status changes in about 1-2 minutes and is recovered back to normal in 1-2 minutes upon being reconnected.

It also affects whole subnets, when I disconnect a router interface and have multiple nodes on a monitored subnet not all nodes will show down.  But some will.

I can not seem to find any reason as to why it affects some nodes and not others.  I am monitoring both Windows systems with agents, and network equipment with SNMP but no correlation seems to be apparent.

my "show queues" at the console all show "0" zeros.

Can someone help me with instructions as to how to troubleshoot this?

Thank you very much, that worked for me!!!

I am starting to use templates in my install to make mass changes easier.  I have a template for windows systems to apply various data collection parameters.  I have applied the template to various systems across several containers.  I have made changes to the template but have noticed that these changes are not applied to the nodes automatically without manually re-applying the template.

I see that the template configuration has a "Automatic Apply Rules", so I entered the following script:

sub main() {
   return $node->isAgent;
}

I am not seeing the changed template "automaticly" applied to the existing nodes.  Am I missing something?

Also I would really like to only apply this to "Windows" agents not all agents but I am not familiar with how to script this.

Please help if you can, and thank you.

tomcat7

the web directory would be /usr/local/tomcat7

Can someone help me with the file locations for a couple of files on a linux based NetXMS server?

I need to create a "nxmc.properties" file to extend the web timeout, but I dont' know where to put it.  I have this working on a Windows 7 box, but that doesn't help me with a linux file location.

Also, I would like to upload my logo and I need to know where to put that file, but of course it can be defined in the nxmc.properties file...

Is there a fast way to move or export a "Container" from the Infrastructure Services tree on one server to a new server?

Here is my steps to install NetXMS 2 beta on a installation of CentOS 6.4 ( 64 bit )

I hope this helps anyone out there that is having a hard time. I attached the steps and put them inline here - they may be easier to read in the attachment:

Thank you Alex, that was my problem.

I installed Java 1.8 64 bit in my case, and removed tomcat 6 - and installed Tomcat 7

A bit of messing with it and it works.

Thank you all for such quick assistance!
