NetXMS Support Forum

Hi all!

We just published another patch release for 4.0 which fixes two important issues:

NX-2210 (Network Service HTTP polling ports above 32767 generates incorrect Host header in HTTP request)
NX-2211 (Agent crash while processing request for System.ThreadCount)

Hi, do you have core dump from crash? If not, could you run netxmsd under gdb until it crashes? If you can, make sure that you have installed the following packages:

netxms-server-dbg
netxms-dbdrv-mariadb-dbg

The run as following in terminal:

gdb netxmsd
On gdb prompt, enter
run -D1

When server crashes, you will get gdb prompt again. Enter command
bt

and share the output.

We just uploaded patched version of UI (version 4.0.2111).

Hi,

probably just ignore them, or set EPP filter to prevent generation alarms. Events will be generated only once for each DCI, so they should stop appearing when new templates will be applied to all old agents.

This actually looks like a bug. Can you provide configuration of your dashboard (you can export it into XML by right click on dashboard object and selecting "Export")?

Hi,

if you have DNS names correctly updated, then you can use DNS names of those devices for communications. NetXMS server will periodically (at configuration polls) check if IP address is the same. You can also force server to make those checks more often by changing configuration parameter Objects.Nodes.ResolveDNSToIPOnStatusPoll from "Never" to "Always" or "On failure".

If you have automatic network discovery then you can turn on parameter NetworkDiscovery.UseDNSNameForDiscoveredNodes - when set server will use DNS name instead of IP address for newly discovered nodes. You should have reverse DNS to be set up properly for this feature to work.

Could you enable SQL trace for some time (this will generate lot of records in log)? Then it will be possible to see all bindings for this query.

You can turn it on while server is running with the following commands in debug console:
debug sql on
debug db.query 9

and to turn back off:
debug sql off
debug db.query -1

Да, у нас с нескольких сторон есть такие запросы. Думаю сделаем в ближайшем будущем.

Hi,

yes, missing policy database error is related to SQLite issue. We will check today.

No, NPI files are no longer needed. Package manager deduces package type from file name, and you can adjust it during import if detection went wrong.

Hi all!

We finally published NetXMS version 4.0. There are lot of new features, changes and improvements, some are visible, some are under the hood. Unfortunately we didn't finish planned changes to UI, so new UI is available as preview alongside old one, and we plan to finalize it during following patch releases.

There are few changes that may cause compatibility issues when migrating from 3.x:

1. Incompatible attributes in NXSL class "DCI": "instance" now refers to instance value (as in {instance} macro), not instance name as before. Instance name can be accessed via attribute "instanceName".
2. Operators print and println in NXSL are now functions, so arguments should be enclosed in brackets as usual for function call.

Below is full change log:

- Two-factor authentication for users
- SMTP implemented as a notification channel and e-mail actions replaced by notification actions
- Added 'DefaultNotificationChannel.SMTP.Html' and 'DefaultNotificationChannel.SMTP.Text' server configuration parametes for default SMTP channel names used by internal functions

We just published updated agent for Windows (version 3.9.446). This agent version correctly reports operating system name when running on Windows 11 and Windows Server 2022.

Then most likely netxmsd process cannot create raw sockets. You can grant it with command

sudo setcap cap_net_raw=ep /usr/bin/netxmsd

(use actual path to netxmsd)

Hi,

unfortunately it is a limitation inside executeSSHCommand function implementation. I've added issue to fix it: https://track.radensolutions.com/issue/NX-2200
