NetXMS Support Forum

Yes your point is valid but I know that is possible, if I change the script and return any value, It appears on dci description.
I would like to know how to do it.

Hi everyone, I have an issue.
I don't know if I'm doing something wrong.
I have following script that I'm going to use to avoid collection of wrong values (hundred of TB)  obtained from snmp "iftable"
I dont get any error (of sintaxis) but the script is not performing any action.
In adition, there is a way to debug this scripts used on transformation tab?. I'm using Windows Server 2012R2 as Netxms Server and PostgreSQL

[script]
interface = GetInterfaceObject($node, ((int)$dci->instance));
speed = interface->speed;
if ($1 > speed){
   return 0;
}
else{
   return $1 * 8;
}

Hello everyone, do you know how can I call a script from a dci description?
for example, this is the description of a dci: TrafficIN %{script:getIfNameByName({instance-name})}
this is my script:
scriptName:getIfNameByName
sub getIfName(netString)
{
     if (length(netString) > 0)
     array a;
     a [length(netString)];
     a = SplitString(netString, " ");
     return (a [
                       (a->size)-1
                  ]
              );
}
return getIfName($1);
how can I call that script and send "instance-name" as parameter?

Hi everyone,
I was looking for a way to create a dci for network traffic on all interface address.
I'm using a template and instance discovery for the process. Now I know that I can use the agent list "Net.InterfaceList" to get interface index and then with Net.Interface.BytesIn64({instance}) get the data I need.
I use following Instance discovery filter script that Alex Kirhenshtein created:
if ($1 ~= "^([0-9]+) .*")
{
       return %(true, $1); // at this point $1 contains first matching group
}
return false;

I was trying to modify regex string to "^[0-9](?!.*127\.0\.0\.1)" to avoid loopback interface.
But I get error "execution error: Error 18 in line 3: Invalid regular expression"
As I couldn't find a way to do it, I use following script
if ((index($1,"127.0.0.1/8")==0)&&(index($1,"::1/128")==0)&&(index($1,"fe80:")==0))
{
     if ($1 ~= "^([0-9]+) .*")
     {
          return %(true, $1); // at this point $1 contains first matching group
     }
}
return false;

Now it works but I tested my regex string on others apps and it worked fine.
Also I was reading that with regex you can "split" the agent list string into multiple values, for example $1:iface Index, $2:IP Address, etc.
although now is working, I'm a bit confuse about regex expressions on netxms. how could I do it the same I do but with regex?
also, when you use regex to get multiple values from a string, how could you asign to multiple variables ($1,$2,etc)

Thanks for your help   

As you said, I have to install that on my Client PC and It works.

Hi,

I have read on some places that if I want to modify supported ciphers I have to use "AllowedCiphers" and/or "EnabledCiphers" options
https://wiki.netxms.org/wiki/Server_Configuration_Variables
https://media.readthedocs.org/pdf/netxms-admin/latest/netxms-admin.pdf

I want to enable only AES256, so I set AllowedCiphers on 1, then restart NetXMS Server and I get a warning "NetXMS Server doesnt support encryption".
I have netxms server 2.08 running on windows server 2012r2, my version doesn't has EnabledCiphers option, so I create the variable and set it on 1.
But I get same mesage. If I set AllowedCiphers to 17, it works.
Do I'm doing something wrong?

Best Regards

Hi,

it was supposed to be fixed in 2.1-M2. Could you please give more details about your environment when 2.1-M2 is now working? Also, could you please try different browsers?

Best regards,
Victor

I have this issue with Netxms Console 2.1-M2 and previous, Web Console 2.1-M2 and previous(Chrome and Firefox).
I have used Windows7 64 bits +Sqlite and Windows server 2012 + MSSQL Server.

Thanks For the Help.
It works. 

Hi all,
sorry for my english, I'm from Ecuador and I don't speak English very well.

I'm using netxms and I think that its great. I have the next problem:
I have some switches cisco 2960, I want to create a template to poll consumed ram from them
I checked cisco documentation and I know that I can get used ram wid oid ".1.3.6.1.4.1.9.9.48.1.1.1.5.1" and free ram with oid ".1.3.6.1.4.1.9.9.48.1.1.1.6.1"
those oid are not tables. The problem is that I dont have a oid to poll used ram in percentage so I create an script that I called SNMPOperations wich calculate percentage consumed.
I have tried this in several ways and I can't figure out what is wrong.
For example:
If I create the script with the function GetValueSNMP that recive a node object and return consumed ram (in percentage)

Script version 1:
sub GetValueSNMP(parameter)
{
   transport = CreateSNMPTransport(parameter);   // "parameter" is a node object
   usedRAM = SNMPGetValue(transport, ".1.3.6.1.4.1.9.9.48.1.1.1.5.1");
   freeRAM = SNMPGetValue(transport, ".1.3.6.1.4.1.9.9.48.1.1.1.6.1");
   totalRAM = usedRAM + freeRAM;
   usedRAMPercentage = ((usedRAM * 100)/totalRAM);
   return usedRAMPercentage;
}
I'm calling previous script in TransformationTab (doesn't work) and Instance Discovery(doesn't work)  in the following way:

use SNMPOperations;
return GetValueSNMP($node);



Script version 2:
   transport = CreateSNMPTransport($node);
   usedRAM = SNMPGetValue(transport, ".1.3.6.1.4.1.9.9.48.1.1.1.5.1");
   freeRAM = SNMPGetValue(transport, ".1.3.6.1.4.1.9.9.48.1.1.1.6.1");
   totalRAM = usedRAM + freeRAM;
   usedRAMPercentage = ((usedRAM * 100)/totalRAM);
   return usedRAMPercentage;
I'm using previous script in Instance Discovery(doesn't work)

I dont know if the script is wrong, or If I'm doing something wrong on dci template.
Please your help.

aalexson Thanks for the help.
Also to inform you. I tried version "2.1-M2" and the issue persist.
Maybe you know if this bug has a number?

I have the same issue with version 2.08 and beta.
Is this a bug ?
Sorry, I want to make sure that I don't have anything wrong in my configuration.

I have the same problem with the version 2.07.
Do I have the same problem if I use a linux distro?

I have the same problem with both consoles, desktop and web.
Netxms server(2.05) is installed on Windows Server 2012 + SQL server 2012
Netxms management console(2.05) is installed on Windows 10

Best Regards

Hi Everyone.
I created a graph on netxms.
It's cool when I select a preset lower that 12 hours, see attachment (preset1.PNG)
But when I select a preset greater than 12 hours, information about day and hours disappear,see attachment(preset2.PNG).
How can I solve this?
Thanks for the help.
pd: sorry if I make a mistake, I don't speak english very well
