NetXMS Support Forum

Hello,

in instance Discovery ...

I configured parameter as Net.Interface.BytesOut({instance}) and in instance discovery I am using Agent List with List name Net.InterfaceList. I found some source code on this forum, so I modified it to:

if ($1 ~= "10.200.*.*")
{
   return %(true, $1);  // at this point $1 contains first matching group
}
return false;

But it is not working, I guess that if statement ($1 ~= "10.200.*.*") is incorrect. I would like to return one instance which start with 10.200 IP address. Any idea how to do that? Thank you

Edit: Well, it is returning whole instance (ifType, IP, MAC Name) ... How I can return only Name?

Ah, I solved it.

I was using template for these parameters and somehow one server refused to rename network interface to Ethernet (it showed as renamed but it wasn't). That's why it was reporting as unsupported ...)

Anyway, do you know how can I filter interface name by the first bytes of IP Address?

For an example, I have 10 network interfaces and one of them has IP 192.168.1.10 and I would like to return this one specific instance which begins by 192.168 ...

Thank you :-)

Hello,

it does not support Net.Interface.BytesOut(Ethernet). This is very strange.

Ok, I solved it by script:

sub main()
{
val1 = GetDCIValueByDescription($node, "Used physical memory");
val2 = GetDCIValueByDescription($node, "Physical memory used for buffers");
val3 = GetDCIValueByDescription($node, "Physical memory used for cache");
return val1 - val2 - val3;
}

Hello,

I draw some graphs of memory usage and I would like to subtract values from Memory free value.

For example: System.Memory.Physical.Used - System.Memory.Physical.Buffers - System.Memory.Physical.Cached to get real used physical memory.

Is it possible to subtract these values in Transformation? If so, how can I call these values? If not, what is the best way to do that? I am new to NetXMS so I am little confused. Thank you :-)

Only to map, I will try to add also devices. Will let you know, thanks :-)

Edit: Yes, that was the problem. Thank you.

Hello, I would like to share some network maps to some users for read only. When I set up access rights in Access Control and user log in to netXMS web interface or Management console he sees network map with Unknown icons instead of devices icon.

Check attachment for an example.

Do you know how to fix it? Thank you

Hello,

I have 5 similar servers running the same Windows version (Windows Server 2012 R2), same NetXMS agents version with the same subagents. One of these servers is reporting error when I am trying to monitor interface traffic via Net.Interface.BytesOut64(*).

Error :Status of DCI 617 (NetXMS Agent: Net.Interface.BytesOut64(Ethernet)) changed to UNSUPPORTED"

Interface name is correct, do you know where could be the problem? I am also experiencing this problem with one Windows 2008 server, but I guess it could be caused by old system.

Thank you in advance :-)

Ok, thank you :-)

Hello, same problem here, only with Cisco C2960 and C3850 devices. (NetXMS 2.0.6 + MySQL)

EDIT: Fixed, it was caused by change of interfaces. Some ports were expected as DOWN and they went UP :-)

Hello, is it possible to monitor memory usage on server per logged user via SNMP or NetXMS agent?

I have terminal server and I have installed NetXMS agent to run per session, but I can't figure out how to do that.

Thank you guys :-)
