I'm trying to add some locations for our devices, and I can't find any instructions for Configuation -> Geographical Areas

I've tried adding in coordinates, one per line, which just results in error saying "Cannot parse area border point".
When I try and import a .kml file, nothing happens.

How am I supposed to use this function?

Thanks,

Thank you.
This Manual page helped immensely: https://wiki.netxms.org/wiki/NXSL:SNMPWalk

The following works perfectly:

// Call this function with the following parameters:
// $1 = port number (eg 5900 for VNC)
// $2 = IP address (xxx.xxx.xxx.xxx)


transport = CreateSNMPTransport($node);
if (transport == null)
           return -1;
oid = ".1.3.6.1.2.1.6.13.1.4." . $2 . "." . $1 ; // IP connections
vars = SNMPWalk(transport, oid);
if (vars == null)
           return -2; // SNMPWalk failed
count = 0;
foreach (v: vars) {
  //trace(1, "SNMP WALK ".v->name."=".v->value);
  count = count +1;
}
return count;


https://www.netxms.org/forum/general-support/how-to-countgraphcheck-tcp-connection-states-table-with-netxms/msg2031/#msg2031 nicely explains how to do it using the Agent, but I was wondering if there is a way of counting OIDs that match a certain criteria without having to have an Agent installed, as some of this is available via SNMP.

For example, OID:
.1.3.6.1.2.1.6.13.1.4.xxx.xxx.xxx.xxx.ssss.yyy.yyy.yyy.yyy.dddd

xxx.xxx.xxx.xxx is the local IP address, and ssss is the local port.
yyy.yyy.yyy.yyy is the remote IP address, and dddd is the remote port.
If I could count the number of times ".1.3.6.1.2.1.6.13.1.4.xxx.xxx.xxx.xxx.ssss.*" appears in the list, I could count how many connections there are to a specific service.

Is this possible somehow?

Thanks Filipp!
I'll try it out.

VMWare Memory, CPU and Storage
Don't ask about other values (IOPS, latency etc), as I haven't figured it out yet, and may require PowerCLI or something annoying 

See attached screenshots for examples.
To make things easier, add the datastore names as persistant storage keys and values.
You can then reference them in the scripts using the name rather than the annoyingly long mount points. Of course there's no easy way of finding out this in the first place, other than SSHing into the server and doing a "df", or looking in the vCenter DataStore sections. Datastore names are not queryable via SNMP as far as I can tell, which is lame.

The template should auto apply, but once they have applied to your servers, you will need to add some DCIs manually using the included scripts to correctly deal with the datastores.
The getVMWareCPULoad(totalCPUUsage) is used to monitor total CPU usage for all cores, as with most VMWare servers, graphing individual CPUs will probably end up with a crazy graph with mainly black lines unless you can be bothered to find 32 different colours for your 32 cores :/
getVMWareCPULoad will add up CPU usage from each core, and using getVMWareCPULoad(totalCPUCountX100) can be used to get a line to show if all cores were using 100%.

Hopefully this is useful. If you have any suggestions on how to add more useful metrics, please let me know!
Thanks

They may be old, but they are still useful. I watched them all to get an idea of how NetXMS worked....

I have followed the instructions here:
https://www.netxms.org/documentation/adminguide/upgrade.html?highlight=upgrade%20agent#centralized-agent-upgrade, but when I try and deploy the agent, none of them work, and I get the message "Agent's version doesn't match package version after upgrade"
I am running NetXMS Server 3.9.298, and am trying to install the agent 3.9.334 and will upgrade the server soon afterwards.
I have never tried this before.

Looking at the agent logs, it seems to be receiving the file in chunks, which are then merged back into the original .exe.
I see this in the log also:
2021.10.29 11:33:38.769 *D* [procexec           ] ProcessExecutor::execute(): process "CMD.EXE /C "C:\NetXMS\var\nxagent-3.9.334-x64.exe" /VERYSILENT /SUPPRESSMSGBOXES /LOG /FORCECLOSEAPPLICATIONS /NORESTART" started
which I guess is good news, but I can't see anything obvious after this.

All agents I am trying to upgrade are on the same LAN, so I doubt it's a network problem.
I ran the above command manually on one of the failing servers, and it worked.

Never heard of wildfly, I will check it out.
We are currently using tomcat 9.0.31 and openjdk 11.0.11.

Hi Filipp,
Thanks for the reply.
Yes, the first command didn't work as it says "GET not supported".
The second command worked, although you need to enclose the "-d" option with single quotes instead of double as double quotes are used in the data.
It looked like it worked:

which I guess looks good. If I change the GUID-type part of the URL it fails, so the URL is correct. I can't check if anything arrived in the Teams channel until I go back to the office on Monday

Thanks, I will try that on the next version!

I am trying to get Grafana to work with NetXMS:

Both are on the same server.
Browsing to the server with /api and /api/info displays version information in JSON format.
I have created the Data Source, and when I click Save & test, it replies with "Data source is working".

When I try and select a Target, the drop down box is empty (I assume it should fill with a list of choices)

When I try and add an alarm list, again, I don't get a list of choices in "Source". If i leave it blank, use "*" or "%" (hoping to show all alarms) I get a JSON reply of column names, but no actual data.

As a test, I've added "allowed_origins = *" to the grafana .ini file as I was seeing some warnings, but although the warnings are now gone, it is still not working.

What am I doing wrong?

When Dashboards get complicated, it's not easy to figure out which element is which, when going back in to edit them.
Would it be possible to add something to make it easier to see which is which, without double clicking on each one to check?
For example, (please see screenshot attached) the title of the element could be added as a new column in the list, so it is more obvious.

Thanks!

I now have quite a few servers I want to monitor for "Node Down", but don't want to just allow everything or i'd get too many alerts as Network Discovery is enabled.
In the IF Condition, the order of the objects seems to be in an odd order (see picture). It doesn't seem to be the order I added them to NetXMS either.
Would it be possible to allow the list to be in Alphabetical order, so it's easier to see if an object has been missed out?

Thanks,

Chris
