Hello

What is the correct way to filter by multiple attributes ?

For example, show tool only when both attributeA and attributeB is present under custom attributes.

Hello

What could cause constant peer hopping between interfaces. I have Mikrotik router with Cisco switch. They are connected via trunk port. In event logs the switch (peer) is constantly changing between Bridge interface and eth 5 (interface with public ip).

Got it working:

File: nxagentd-ssh-config.confHostKeyAlgorithms ssh-dss
KexAlgorithms diffie-hellman-group1-sha1

Any other ideas ? Would be quite bad if Netxms support for Mikrotik ssh is broken.

Still no go.

Did the following:

nxagentd.conf

[SSH]
ConfigFile = D:\NetXMS\etc\nxagentd-ssh-config.conf

nxagentd-ssh-config.conf
HostKeyAlgorithms +ssh-rsa

restarted agent. In router ssh debug CL line doesent include ssh-rsa

Seems like its not working when i change agent conf to include

[SSH]
HostKeyAlgorithms +ssh-rsa

and restart agent. "cl" line didnt change in debug.

ssh debug from router: https://ibb.co/pwxSv02

Hello

Has anyone experienced following issue: I have set NetXms to poll Mikrotik router via ssh and each time when attempt is made, router generates error "can't agree on KEX algorithms". When i log in manualy via ssh, then no error. Seems like it started with NetXms version 3.5.90. It used to work on older version and polling script hasent changed.

Egert

Hello

With versions 3.5.90 the issue is still present, agents with high cpu usage cant be upgraded. Error message is "File transfer failed".

Egert

But not possible with ssh ?

Is it possible to send config change to cisco switch (2960x) with scheduled action ? For example move interface to different vlan ?

Hello

How hard would it be to make alert based on historical trends? For example if interface speed is unusualy low for given period.

Egert

Hello

Would it be possible to add shortcut to node right click menu, where link to maps would be shown (list of maps where speific node exists)?

Egert

Hello

Version is latest. I got it fixed by removing records from snmp_ports tabel. There were two records, both with id 1. After migration completed i re added settings with netxms.

Egert

Hello

Any tips how to solve following error message, i get it when trying to migrate from MSSQL to Postgresql?
