А какой хеш был?

Сбросить можно было вот так (без работы с базой напрямую): nxdbmgr resetadmin

Hello.

First of all, you don't have to match message for that. SYS_IF_UP (SYS_IF_DOWN is the same) have 5 parameters, and 3rd one is ip address (check description in event editor).

So you can change script to if ($3 == "0.0.0.0") {
  return true;
}
return false; or even (if you don't have any other logic in the script) $3 == "0.0.0.0"

Then opposite script will be if ($3 != "0.0.0.0") {
  return true;
}
return false; or $3 != "0.0.0.0"


Problem with your original script was invalid syntax, instead of if ($event->message !like "0.0.0.0/0.0.0.0"){
  return true; // Match rule
}

if should've been

if (!$event->message like "0.0.0.0/0.0.0.0"){
  return true; // Match rule
}

Check that server's ip is in MasterServers in agent config.

Hello.

There are no out of the box solution for that.
I'd write some kind of script which will connect to mikrotik (over ssh or telnet), parse "ip hostspot active" command and produce per-user output in format of external parameter provider (https://wiki.netxms.org/wiki/ExternalParametersProvider)
I also suggest to create second script, which will return only customer names, this way you'll be able to setup instance discovery (https://www.netxms.org/forum/configuration/create-agent-list-for-instance-discovery/)

Hello.

Sorry for late reply.

It's definitely an issue with database performance, queue size is way to high.
1) Check "EnableMultipleDBConnections" parameter (either in server settings or using "nxdbmgr get EnableMultipleDBConnections"), it should be set to "1"
2) Check "ConnectionPoolBaseSize" and "ConnectionPoolMaxSize". Server can be very slow if poll size is limited to 1.
2) Increase number of DB writers to at least 4 ("nxdbmgr set NumberOfDatabaseWriters 4")
3) Check I/O, enable slow query logging

Please note "nxdbmrg set" should be used only when server is stopped.

Use script to generate action message, as I explained in https://www.netxms.org/forum/configuration/using-value-of-other-dci-in-description/.

Hello.

It depends on what you want to achieve.
If you need that for notifications – you can use custom script to format message("%[ScriptName]" macro). Example:


And script ("CustomScript" in script library):if ($event->id == 17) { // SYS_THRESHOLD_REACHED, adjust to real event
if ($event->parameters[1] == "System.Memory.Physical.Used") { // $1 is "Parameter name" for SYS_THRESHOLD_REACHED
total = GetDCIValueByName($node, "System.Memory.Physical.Total");
return "Too much physical memory used (" . $event->parameters[4] . "), total: (" . total . ")"; // $4 is "Actual value"
}
}
return $event->message;

This is just an example, you need to adjust it to match your setup (e.g. if this action is used only for specific event in EPP, you can omit $event->id check the script).

A bit more about using scripts in actions: https://www.netxms.org/forum/configuration/actions-parameter/msg3178/#msg3178


If you need event with both values (e.g. for further processing), you can post custom event from transformation or threshold script (https://wiki.netxms.org/wiki/NXSL:PostEvent)

Скриптами можно сделать List:ExternalList=TestList:ls /mnt/backup_201|grep SERVER
Который потом можно использовать в Instance Discovery.

Hello.

Yes, it's known issue. We are rewriting documentation at the moment, it will include complete quick start guide.
While it's not available, please check these video tutorials from Tomas Kirnak: https://www.youtube.com/playlist?list=PLt3aE2eGS5P9L72H82S83MrKx2uz5x8gv

Components:
Server – collects data from agents and SNMP devices, process this data, react on threshold violations, etc.
Agent – daemon, which provide OS-specific metrics to server (e.c. CPU usage, file system information, process information, etc.). In SNMP-only environment agent is optional; however it's recommended to run agent alongside with netxmsd

Ports:

4700 – is used by the agent, server (or debug tools like nxget) connects to agent on this port.
4701 – is used by management console for connection to netxmsd.

Management console always connect only to the server, not to agents directly.
Server connect to agents.

"MasterServer" is a whitelist of the IP addresses, which are allowed to connect to the agent. You need to have at least netxmsd's IP in this list. If it's running on the same machine, I'd recommend to add "127.0.0.1" as well. List is separated by comma, you can also use CIDR notation to specify subnets (e.g. "MasterServers=127.0.0.1, 10.0.0.0/24").

Добрый день.

Это разные реализации Python. Модули поставлены в системный CPython, а nxshell основан на Jython.
Jython написан на джаве, и поддерживает только pure-python модули (без компилированных библиотек).

Внешние модули можно загрузить, добавив путь к ним в sys.path:
AirAlk:~() $ java -jar ~/.m2/repository/org/python/jython-standalone/2.7-b4/jython-standalone-2.7-b4.jar
Jython 2.7b4 (default:3672e624962a, Feb 13 2015, 04:59:14)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_25
Type "help", "copyright", "credits" or "license" for more information.
>>> import xlrd,xlwt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named xlrd
>>> import sys
>>> sys.path.append('/Library/Python/2.7/site-packages')
>>> import xlrd,xlwt
>>> xlrd.__file__
'/Library/Python/2.7/site-packages/xlrd/__init__.py'
>>> xlwt.__file__
'/Library/Python/2.7/site-packages/xlwt/__init__.py'
>>>

Add instance discovery script:

if ($1 ~= "^([0-9]+) .*")
{
   return %(true, $1);  // at this point $1 contains first matching group
}
return false;

It's required because this list return more data than interface index:
AirAlk:~() $ nxget -l 10.5.0.111 Net.InterfaceList
1 127.0.0.1/8 772 000000000000 lo
2 10.5.0.111/24 1 00163E000009 eth0

Instance discovery is performed on configuration poll.

Добрый вечер

Выложил сборку: https://www.dropbox.com/s/wd8ag9ug6hl58iu/nxshell-1.2.17-jython-2.7-b4.jar?dl=0

Если хочется собрать самому, то как-то так:

git clone https://git.netxms.org/public/netxms.git
cd netxms
git checkout v1.2.17
patch -p1 < nxshell-new-jython.patch
cd src/java
./package.sh
cd nxshell
mvn package


Патч делает две вещи: меняет версию Jython с 2.7-b1 на 2.7-b4 и чинит ошибки сборки на слишком новом Jython-е.
Для сборки нужен Apache Maven и JDK.

Пример, как настроить сбор данных по SNMP, есть тут: https://www.youtube.com/watch?v=fbWkkzI0XNA&list=PLt3aE2eGS5P9L72H82S83MrKx2uz5x8gv&index=8
