Est' dva varianta:

1. Dobavit' ciscu, dozdatsja okonchanija configuration poll, posle chego postavit' v nastrojkah "disable configuration poll" i udalit' ne nuznie interfeisi i subneti.
2. Sdelat' vse nenuznie interfeisi "unmanaged" - togda oni ne budut oprashivatsja. (massovoe izmenenie sostojanija interfejsov mozno sdelat' na zakladke "subordinates" object browser'a).

Добрый день!

Имеется ввиду отключить добавление самих объектов подсетей, или отключить дискавери внутри этих новых сетей? Если второе, то это можно сделать только фильтрами автодисковери. Первое на 100% нормально сделать нельзя - можно запретить делать configuration poll для узла в Properties -> Polling, но при этом и проверка остальных capabilities (версия SNMP, isRouter, isBridge, etc.) будет отключена. А зачем это нужно?

Сначала командой nxencpasswd получить шифрованный пароль, и в netxmsd.conf использовать DBEncryptedPassword вместо DBPassword. Например, было:


DBLogin = netxms
DBPassword = password


делаем


C:\Source\NetXMS\debug>nxencpasswd.exe netxms password
mMHptlOwBjoW7jJ3wyzp2JHdUEDiLt73kd1QQOIu3vc=

C:\Source\NetXMS\debug>


и обновляем netxmsd.conf:


DBLogin = netxms
DBEncryptedPassword = mMHptlOwBjoW7jJ3wyzp2JHdUEDiLt73kd1QQOIu3vc=


Hi!

There are no single standard "fault" OID. Usually, there are some vendor-specific OIDs from where you can get CPU utilization, memory usage, etc. and set your own thresholds. There are also standard OIDs for network interface errors. Also, you can setup SNMP trap processing, but again, it will be vendor-specific.

Hi!

NetXMS server reads SNMP variable .iso.org.dod.internet.mgmt.mib-2.ip.ipForwarding (.1.3.6.1.2.1.4.1) to determine if node is able to forward IP packets. Value of 1 indicates that IP forwarding is enabled on the node, and in that case NetXMS server sets isRouter attribute to true. Could you please try to read this variable using nxsnmpget or any other tool?

Victor

Dobrij den'!

Poprobujte zamenit' fail dbschema_sqlite.sql (nahoditsja v C:\NetXMS\lib\sql) na prilozennij.

Hi!

I mean that in passive mode NetXMS uses data from known devices to find new devices. For example, you have one device in NetXMS - router with IP address 10.0.0.1 accessible with SNMP. During discovery poll, server reads ARP cache and routing table from that router. For example, it founds two entries in router's ARP cache - 10.0.0.7 and 10.0.0.44. NetXMS then adds new devices with addresses 10.0.0.7 and 10.0.0.44 (if filter does not prevent it), and do discovery poll on them if possible - and that process repeats for each found device. You need active discovery only if you have devices which may not communicating with already known devices, so they will not appear in known devices' ARP cache.

And yes, pinging all IP addresses on subnet can take very long time, especially if you have many unused addresses, because server will wait for possible reply for each address.

Hi!

Could you please provide exact command which does not work?

You should create two DCIs, and transform one of it using value from another. For example, define DCI for interface speed (.1.3.6.1.2.1.2.2.1.5.1); leave it as is. Then, define DCI for inOctets (.1.3.6.1.2.1.2.2.1.10.1), and set transformation script to


sub main()
{
   ifSpeed = GetDCIValue($node, FindDCIByName($node, ".1.3.6.1.2.1.2.2.1.5.1"));
   return ($1 * 8 / ifSpeed) * 100;
}

Hello!

In passive mode, NetXMS server only collects information about network devices by reading ARP caches and routing tables on already known devices. In active mode, server additionally pings every address in given subnets and uses responding addresses as well.

Network discovery can take many hours or even days, it depends on network size. Also, don't forget that NetXMS server should have SNMP access to as much network devices as possible to be able to obtain required information.

You can discover all reachable devices and networks, just make sure that your devices and firewalls allows SNMP requests from NetXMS server.

Test button will work only for nodes (not templates) - because test is done by sending script to server and running it in context of specific node.
For testing scripts where $node variable is not used you could also use nxscript command line tool. If using nxscript, first command line argument will be passed to script as $1, second as $2, and so on.

Ja poprobuju u sebja povtorit' etu situaciju. Kak workaround, poprobujte vibrat' "use existing database" - esli baza uze sozdana i prava na nee est', to vse dolzno srabotat'.

What exact error you got? Is it entire script or just a fragment? If it is entire script, you should write it as

sub main()
{
  if ($1 == null)
     return 0;
  else
     return ($1 * 2);
}

or rewrite as

($1 == null) ? 0 : $1 * 2

Hi!

Could you please try version 1.0.0? I've fixed some bugs in interface poller, should help.

Hi!

In this case, 3 is number of retries, and ping timeout is 1500 milliseconds. Unfortunately, this value is hard-coded (file src/server/core/interface.cpp line 329).
