Hi!

Can you check please what driver was selected for these switches? Cisco has very specific way of providing MAC address table for VLANs other then VLAN 1, so this may be the case. Catalyst driver supposed to handle this, but maybe there are bugs in the driver, or correct driver was not selected at all.

Hi!

We know that there are installations with more then 3000 nodes. Potentially system can handle hundreds thousands nodes - actual capacity mostly depends on how often you collect data, how much data you collect, and your network bandwidth.

Hi!

Can you confirm that problem on 1.2.7 as well? There was some fixes in node polling. This bug is so strange...

Hi!

Script looks correct. But are you sure that .1.3.6.1.2.1.25.1.5.0 is writeable, and that community string set in NetXMS allows read/write access?

Hi!

You can turn on global event storm detection by setting server's configuration variable EnableEventStormDetection to 1 (you'll have to restart server). You can set number of events to trigger event storm condition in EventStormEventsPerSecond parameter, and for how many seconds number of events mus be above threshold in EventStormDuration parameter.
Another option is to implement counter using situations, and don't send email if certain threshold reached.

Hi!

Can you please attach your config.log?

Все настройки сервера хранятся в базе, так что достаточно перенести базу, проинсталлировать NetXMS сервер на другой машине, и подключить к скопированной базе. Базу можно перенести через nxdbmgr export / nxdbmgr import, или средствами самой базы. Если база SQLite, то достаточно просто скопировать файл базы.

Работа по локализации начата вообщем-то, надо продолжать Локализация для десктоп и веб интерфейсов общая. Уже сейчас веб можно переключить на русский, добавив ?lang=ru к URL'у. На русском правда будет только несколько пунктов меню. Самый правильный вариант думаю будет такой - я подготовлю новые message-файлы, и пришлю вам для перевода. На форуме есть ветка, посвященная локализации консоли: https://www.netxms.org/forum/general/about-the-language/ .

Hi!

NetXMS should work with any SNMP-capable device. You can create links on map with any name set. However, there are no dynamically updated information on the links yet.

In enterprise WiFi system, you usually have wireless switches (controllers) and access points. In most cases access points are not directly accessible, and all management information must be read from controllers. Starting from 1.2.7, NetXMS can read information from wireless controllers and create separate access points objects that can be used on maps, etc. Support from network device driver is required for this functionality. Currently we have driver for Motorola/Symbol wireless controllers.

Hi!

Currently map object status is always NORMAL. I will add an option for map to calculate status based on underlying objects. Currently you can use containers if you want to see status - but that's a double work. For example, you can create container C and map object M. Then you add nodes to both of them, and set map object M as a drill-down map for container C. Then you can add container C to top-level map. You will see it's status depending of underlying nodes status, and if you double click it, map M will open.

Your script has syntax error, and so it not compiles. Because of that you got "script not found" message (not very meaningful in this case, I agree). Besides that, it has other errors. First of all, you have to create SNMP transport object for node you want to query, and then use it in SNMPGet function. Below is an example of script which can be run from server's debug console to get SNMP object ID from node passed as parameter:


if ($1 == null)
{
   println "Please specify node name as parameter";
   return 3;
}

transport = CreateSNMPTransport(FindObject($1));    // Create SNMP transport for node
if (transport == null)
{
    println "Failed to create SNMP transport, exit";
    return 1;
}

value = SNMPGetValue(transport, ".1.3.6.1.2.1.1.1.0");
if (value == null)
{
    println "Failed to issue SNMP GET request";
    return 2;
}
else
{
    println "System description: " . value;
    return 0;
}


Example of running this script on my test server attached.

Hi!

This can happen if counter resets to 0 at some point. Then delta between new value of 0 and previous value if very large. You can prevent such incorrect spikes by checking for reasonable maximum value in transformation script. For example, if max. possible value for inbound is 600000, you can use transformation script like this:


return ($1 <= 600000) ? $1 : 0;

Hi!

Yes, it's possible, you have to install web UI for that. It's in a separate package: https://www.netxms.org/download/webui/netxms-webui-1.2.7.exe or https://www.netxms.org/download/webui/netxms-webui-1.2.7-x64.exe. If you already have Java application server installed, you can just deploy war file: https://www.netxms.org/download/webui/nxmc-1.2.7.war. There is short instruction about web UI installation: http://wiki.netxms.org/wiki/Web_Interface_Installation_Guide.

Hi!

There are lot of different options for different integration scenarios. One option is to use event forwarding between NetXMS servers: collector server collects and analyzes data from devices, and send events to operations manager server when something happens. In such configuration historical data will be kept at collector server, but important events will be available on central server. If you prefer to use other collection tools, you can use integration utilities to send events and data to central NetXMS server (nxevent for sending events and nxpush for pushing performance data).
NetXMS agent is able to parse log files and send events to server when match is found. It cannot forward SNMP traps. Agent is not collecting data automatically - only by server request.
