Hi,

there are some incompatibilities in dlls. We will publish release 2.2.12 with a fix tomorrow.

There is MySQL monitoring subagent, it could possibly work on MariaDB as well, but it seems to be not documented. You can get some information from it's source code here - https://github.com/netxms/netxms/tree/master/src/agent/subagents/mysql and I will ask next week to update administration guide as well.

Hi,

do those DCIs recover by itself afterwards? Could you set debug level for server to 7 around that time and check for lines with text GetItemFromSNMP? But keep in mind that debug level 7 will produce huge amount of logging, so depending on your system size it may not be a good idea). Could it be that housekeeper start time set around 1:30?

Hi!

Looks very strange. Could you post screenshots of your DCI configuration? Also, is it template DCI or you configure it directly on node?

Hi,

I have found the bug. Please try to replace libnetxms.dll to attached.

Best regards,
Victor

Looks like something is wrong with binaries. Please try to update using this installer: https://cloud.netxms.org/index.php/s/gWYF0hHo9mFzLKU It also contains mysql.ddr with additional logging.

Best regards,
Victor

Did you install 2.2.11 from minimal or full installer?

Could you provide md5 sum of downloaded file and original file?

Please try replacing mysql.ddr with attached one. It should print additional diagnostic line when query fails.

Best regards,
Victor

This looks like a bug in MySQL driver. I'm currently looking at it.

Hi,

looks like we did not rebuild libmosquitto (we ship agent with our own build) after moving to OpenSSL 1.1. Attached is correct version of libmosquitto.dll - replace old one in NetXMS\bin and subagent should start. I assume you have 64 bit system - let me know if you need 32 bit version of dll.

Hi,

this query is executed when DCI data is read for showing on graph or for export. Do you have any issues with displaying DCI data?

Best regards,
Victor

2. другое устройство сообщает ту же подсеть, но с другой маской
пункт 2. совершенно нелогичный. Не бывает "такой же подсети, но с другой маской". Подсеть - это всегда комбинация из Subnet ID и Subnet Mask. Например, 10.0.0.0/24 и 10.0.0.0/16. А "суммирующая" подсеть - это совершенно другое. SYS_INCORRECT_NETMASK путает теплое с мягким.

Речь не идет о суммирующей подсети. Например: чистая система, добавили устройство А. С устройства сервер получает интерфейс с адресом 10.10.10.1 и маской 255.255.255.224. Создает подсеть 10.10.10.0/27. Потом добавляем устройство B. С него получаем интерфейс с адресом 10.10.10.2 и маской 255.255.255.0. В этот момент генерируется событие SYS_INCORRECT_NETMASK, поскольку на одном из устройст маска сети однозначно неправильная. Поскольку сервер не может знать, на каком именно, то принимает что первое найденное устройство имеет правильную маску, а вновь добавленное - нет.
Проблема неверных SYS_INCORRECT_NETMASK может быть, когда при добавлении устройства данные о маске получить нельзя - тогда создается сабнет /24 (это можно поменять параметром DefaultSubnetMaskIPv4).

Hi,

am I understood correctly that actual returned value contains floating point number and text "kW"? If yes, Java consider it as string and do not allow numeric formatting. You can change DCI data type to floating point number and use transformation script to remove unit indicator, like this:


if ($1 ~= "([0-9.]+) kW")
   return $1;
return $1;
