Hello everyone,
We're participating in a tender, and are calling for testimonials from companies, which use NetXMS for monitoring data centre's infrastructure. Does anyone of you use NetXMS for monitoring a data centre and would be able to sign such recommendation letter? Please, reach out to me, I can also send you a draft/ example of such letter, if needed. 
Thank you all in advance for your support.

Because we have both MySQL client and MariaDB client on common include path (MySQL going first) during Windows build, we cannot use
#include <mysql.h>
in MariaDB driver as it will pick up header file from MySQL client. So we creat simple header file called mariadb.h and place it besides mysql.h from MariaDB client:
#include "mysql.h"
#include "errmsg.h"

Best regards,
Victor

Agent reads registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall to get list of installed products.
I tested WMI query on Win32_Product on my Windows servers, and it seems to work, but is very slow (usually more than 10 seconds). Normally agent command timeout is less than that, so data collection end up in error.
Could you use System.InstalledProducts table instead?

Best regards,
Victor

Quote from: hmjvaline on November 06, 2024, 03:03:35 PMI am shock netxms 5.1 is limited to 250 nodes  
It reduced my enthusiasm for NetXMS and even gave up on it because it is no longer so open and free. Although I have never needed the company's institutionalized services, I feel discouraged by this new restriction.

You know, even open source developers need money for living. And purchasing support contract for using open source product pre-built for Windows platform is not a big ask in my opinion. 250+ devices is not a small deployment, so likely organization is not that small either, and do not hesitate paying license fee for Windows servers.

Just to make sure we understand setup correctly: you are using desktop client on Windows workstation, connecting to remote server that is also on Windows and using MS SQL database?

This is fixed, fix will be part of release 5.1.

So the problem here is that AP in question does not support neither LLDP nor CDP (not even spanning tree), so there is no way of getting topology information from it. CDP/LLDP not being supported in this context only means that information collected via those protocols is not made available via SNMP, even if device can send/receive CDP or LLDP packets.
If there is topology information available through vendor MIBs, then we probably can implement topology information reading on driver level.

Screenshot below shows how we do it. Basic idea is not to send "node up" notification if timer for "node down" notification was not fired yet. Note that rule order is important in this setup.
