Hello!

Usually you should be able to upgrade any version of agent. Most likely there are a problem with specific system. Agent installer should left logs in /tmp on target machine - could you please provide them?

Best regards,
Victor

1. How do we disable alerts and notifications of a sys_node_down\sys_node_up status during a set time period?  For example, during the 12am to 4am hours, the majority of our servers go through a restart process.  How do we configure the scheduling so that the email notification of sys_node_down and sys_node_up are not captured over a certain time period?

You can achieve this by adding additional filtering script to the rule. Script for checking if current time is not between 00:00 and 04:00 (04:00 not included) may look like following:


sub main()
{
   now = localtime();
   return now->hour >= 4;
}

2. How do we configure the email alerts to only send once email every 5 minutes and stop after 4 emails when a sys_node_down event occurs.  In other words, we've created an event processing policy for sys_node_up and sys_node_down for sending an email notification once when an event occurs.  How do we create an email event so that we are notified once every 5 minutes with a max of 4 emails?

There are no easy way to achieve this. However, you can try the following:

1. Create custom event, like NODE_STILL_DOWN;
2. In processing policy, add action that runs a script on server; this script should run nxevent tool four times to post NODE_STILL_DOWN event to server four times with 5 minutes interval, and then exit;
3. Add event processing policy rule for NODE_STILL_DOWN event - it should check if node is still down and if yes, send additional email.

Hope this helps!

Hello!

It's a bug in configure. I'll fix it and put updated version on web site.

Сделал очередное теоретическое исправление, NetWare сервера для тестов пока нет. Попробуйте заменить libnxlp.nlm на приложенный - теоретически проблема должна пропасть.

Hello!

In this topic you could find some information about custom trap configuration: https://www.netxms.org/forum/index.php/topic,9.0.html.

As first step in troubleshooting, set server's variable LogAllSNMPTraps to 1 and check if traps are received by server at all.

Yes, it should work on OpenBSD.

Hello!

API is available, but for C++, not plain C. You will need libnxsrv and all it dependencies to use it. API is not documented, but is very straightforward:

1. You should create object if class AgentConnection;
2. Call Connect() method for it;
3. Call GetParameter() method to retrieve data from agent (you can call GetParameter multiple times to retrieve multiple parameters);
4. Destroy connection object.

There are command line tool called nxget which can be used to retrieve data from agents. You can use nxget's source code as a reference to build your own communication tool.

Hello!

Most likely you have entered OID incorrectly, or your device really does not support it. Could you please post some screenshots?

Hi!

You can export active alarms into comma-separated file using nxalarm tool. For terminated alarms and events the only way to export is to query database directly. Alarms stored in table alarms, and events in table event_log. Ask if you'll need comments on structure of these tables.

Best regards,

It's a bug (or confusing feature) in event viewer. If event is not marked as "write to event log", then it will not be written to database. However, server notifies all connected clients about all events, and if event viewer is open at this moment, then event is displayed. If you close event viewer and open it again, you'll see that all past events without "write to event log" mark disappeared.
In a new console, event viewer will be separated to two different views - real time event monitor, which will show all events as they coming, and event log viewer, which will show events actually logged in database.

We know we use to have a pc with IE6 to get it working but it works.
Also we tried the webinterface and Alarm tab... problem here is that the alarms are not updates realtime... something what is great with Alarm Viewer.

We have some slight problems with it :

- Alarm Viewer need to be reset couple of times a day
- We want to change background so it stays changed (we can change it while started in the folder... but with a restart it's gone)

Both alternate background for Alarm Viewer and automatic refresh of alarm list should be easy to implement. I'll try not to forget and add it to next release.

Than i have also a question about Alarm Notifier.. some cool tool which runs in my system tray all the time.
I want to install it at home so i get the alarms there too is that possible... so yeah which ports it uses so i can put it in my ISA server.

All client tools use TCP port 4701 to connect to server.

Hi!

I still have not solved problems with .apkg installer, so I put agent version 0.2.31 for IPSO as simple archive (https://www.netxms.org/download/agent_packages/nxagent-0.2.31-ipso.tar.gz). Extract it inside /opt directory and run /opt/netxms/bin/nxagentd as usual. Agent linked statically with all subagents.

Spasibo za log, vrode ponjal gde problema. Postarajus' segodnja peredelat' i vilozu obnovlennuju versiju.

Добавил такую возможность в 0.2.31. Теперь полный формат File.Count и File.Size выглядит так:

File.Count(path, pattern, recursive, size, age)

где:

path        Путь к файлу или каталогу
pattern    Маска для выборки файлов
recursive  Индикатор рекурсии - если выставлен в 1, то агент будет искать файлы в подкаталогах, если 0 - то нет
size         Фильтр по размеру; если 0 - фильтра нет, если < 0 - берутся файлы с размером меньше abs(size) байт, если > 0 - берутся файлы с размером больше size байт
age         Фильтр по возрасту файла;  если 0 - фильтра нет, если < 0 - берутся файлы со временем изменения меньше чем abs(size) секунд назад, если > 0 - берутся файлы со временем изменения больше чем abs(size) секунд назад

Например:

File.Count(C:\TEMP, *.dat, 0, 0, 600) - количество файлов с расширением .dat в каталоге C:\TEMP, измененных раньше, чем 10 минут назад, без учета файлов в подкаталогах.
File.Count(C:\TEMP, *.dat, 1, -1000) - количество файлов с расширением .dat и размером меньше 1000 байт в каталоге C:\TEMP и подкаталогах.
