NetXMS Support Forum

During the last days, I upgraded our 2.2.12 NetXMS to 3.9.334 (mostly painless).
I also upgraded the agents on most of our servers (with the exception of some CentOS6 machines).

However, I was used to restart the agent from the console (Node=>Tools=>Restart agent).
With the 3.9 agent, this works only on the Windows servers.

On CentOS7, this stops the agent (and requires manual restart on the target machine).

Do I miss some configuration option ?

Regards,

Thomas

Hi,

on one of out workstations nxmc refuses to start.
We are not aware of any changes to this specific system (the console runs fine on other similar Windows installations).

This is an installation including the Java Runtime.

We tried
- nxmc.exe -clean
- reinstalling console (including the embedded JRE)
- rebooting the system (several times)

Do you have any hints in this regard ?

Please find below an excerpt from the logfiles (complete logs are attached).

Thank you very much,

Thomas

Hi all,

we just found is a small inconsistency in the "Alarm summary" email, where we find a "Node Down" event for a node we deleted a few days ago.
The alarm is not visible in the F8 Alarm browser.
This might be related to an update (we updated from 2.1 to 2.10 around time when the node was removed).

Both Config entries "DeleteAlarmsOfDeletedObject" and "DeleteEventsOfDeletedObject" are set to 1 (default).

I will apply https://wiki.netxms.org/wiki/Reseting_state_of_all_alarms_and_node_statuses to resolve the issue.

Kind regards,
Thomas

Hi,

I'm currently trying to get an external parameter on a Windows host working.
NetXMS Version as well as the Agent version is 2.1.

The Agent Policy

ExternalParameter=Ext.grep_count(*):powershell.exe -command "Select-String -Path \"$1\" -Pattern \"$2\" | Measure-Object | Foreach-Object { echo $_.Count }"

gets called, but reports "_.Count" as value of the Parameter.

I assume that the "$_.Count" gets replaced by NetXMS somewhere by "_.Count", so the echo returns this string only.

Is there a way to escape "$" in the Agent Policy ? I already tried to "\$_.Count" (returning \.Count as value).

Kind regards,

Thomas
PS: as the External parameter is called, I think you can cancel https://track.radensolutions.com/issue/NX-1233

Hi,

installing a policy containing german Umlauts might truncate my policy file.

I just added a comment like below:

The resulting file in /usr/local/var/lib/netxms/config_ap looks like

...

Removing the Umlaut in the comment transfers the entire file.

Hi,

I'm using some agent policies to add a bunch of external Parameters for Windows and Linux hosts.

This works well on Linux - policy files get saved in /usr/local/var/lib/netxms/config_ap/, Parameters become visible after Agent restart and Config poll.

On Windows, the policy files appear in C:\Windows\System32\config\systemprofile\AppData\Local\nxagentd\config_ap\, but the Parameters contained here do not show up after restart/config poll.
However, adding the very same Parameters to nxagentd.conf works as expected.

Setting FileStore in nxagentd.conf has no effect.

Agent was installed using the nxagent-2.1-M2-x64.exe file.

Is this a bug or do I miss something ?

Kind regards,
Thomas

Hi,

I'm having troubles to get the instance-discovery by script working.

I have:
- Instance Discovery Method: Script
- a Filter script (in the moment just tracing)

However, the filter script doesn't get called - I assume the array returned by list_attributes_by_key() does not find it's way to the instance discovery.
When running the script via "Execute server script", I get the debugs (trace, println) printed.

Can someone point out my error with this ?

Kind regards,
Thomas

Script "list_attributes_like_http"

foreach (entry: a)
{
msg = "like http: " . $node->name . " " . entry;
trace(1, msg);

return a;


"list_attributes"

Hi,

the problem I have is with with a fresh installation of NetXMS 2.0.8 (also tried 2.0.7 and 2.1-M1).

Changes to templates are fine as long netxmsd is running, but disappear when netxmsd is stopped/started.

I tried NetXMS 2.0.7 and 2.1-M1 with sqlite and postgresql databases.

With the postgres backend I get some SQL errors (below), the sqlite backend does not show any SQL errors.

Is there something I miss ?

Kind regards,

Thomas
