NetXMS Support Forum

Hi,

when you do search for IP address, server will find node with that IP address, and show you MAC address of interface where this IP address is configured. You get specific MAC because you are looking for specific IP. When looking for a node by it's ID you have to somehow decide what interface to use. You can use primary IP address for example to determine what interface and MAC address to show.

Hi,

please verify with command show flags in server debug console if flag AF_RESOLVE_IP_FOR_EACH_STATUS_POLL is actually set.

Hi all!

We just published next patch release for NetXMS 3.8 - version 3.8.350 (3.8.251 for Linux agents). Changes since previous patch release:

- Added notification channel driver for SNMP traps
- Event processing macro %K (alarm key) also works in rules following one that triggered alarm
- Improved Data Collection Editor and Policy Editor usability
- DCI instance used for custom attribute lookup when expanding %{} macro
- Fixed sorting for "Object query" dashboard element
- Fixed memory leak in server related to "Object query" dashboard element
- Fixed issues:
        NX-2022 (Rack with custom height is incorrectly displayed)
        NX-2028 (Use instance name for custom attribute search when expanding %{} macro)
        NX-2029 (Line Chart General Time Period keeps reverting to "Back from now" when trying to use "Fixed time frame" option)
        NX-2031 (HTTP proxy parameter configured in nxmc properties has no effect)

Hi,

it does, but very limited. You can configure cluster object and register virtual IPs - NetXMS will then monitor if virtual IP address is moved from one node to another and if it is present. It cannot monitor resources without associated virtual IPs.

Hi,

are you running server on Windows?

You can actually try upgrade to 3.8 - we did change framework version 3.7, so that may help. And 3.2 is quite old anyway, lot of other fixes and improvements were made since its release.

Hi,

you can use any database present on that server then, probably "master" could be a good choice as it always exists.

It is considered down, but status for the interface is set to "Minor" instead of "Critical" if operational state is DORMANT and expected state is UP. If expected state is DOWN and interface is in DORMANT state, then status will be "Normal" because interface is down in a sense that it does not pass operational packets. I don't think there should be expected state DORMANT (as far as I understand it it is more of an exception state that expected to be solved, so it is kind of pointless to expect interface to be in that state normally).

Hi all!

New patch release for NetXMS 3.8 (version 3.8.226) is just published. Changed since previous release:

- Lower memory footprint of NXSL scripts
- Correct handling of agent policies by external subagents
- Added attribute "tunnel" to NXSL class "Node"
- Server runs configuration poll on node after agent upgrade
- File manager subagent does not register same root multiple times
- Fixed refresh issues in Object Details view
- Fixed visualization issues in switch port view
- Fixed incorrect root object filtering in dashboard elements "Event Monitor", "SNMP Trap Monitor", and "Syslog Monitor"
- Fixed issues:
        NX-2014 (Create NXSL property on node object that gives reference to each type of proxy)
        NX-2024 (Add "Max Wait Time" to Server.EventProcessors Internal Parameter Table)

Hi,

you could choose OID right before doing actual SNMP request in script DCI - so no extra SNMP requests will be done. Like this:

switch($node->vendor)
{
   case "Mikrotik":
      switch($node->productName)
      {
         case "60ghz": oid = ".1.3.6.1.4.1.14988.1.1.1.8.1.6.1";
      }
      break;
   case "Ubiquity":
      switch($node->productName)
      {
         case "AirMAX": oid = ".1.3.6.1.4.1.41112.1.4.1.1.4.1";
         case "AirFiber": oid = ".1.3.6.1.4.1.41112.1.3.1.1.5.1";
      }
      break;
}

if (oid == null)
   return null;  // OID was not selected, null will mark DCI as unsupported

snmp = $node->createSNMPTransport();
if (snmp == null)
   abort;
return SNMPGetValue(snmp, oid);


This of course relies on correctly set vendor and product name values. This should be the case for Mikrotik devices, but may not be for Ubiquity - you should double check.

Alternative approach could be probing for different OIDs in configuration poll hook andd setting correct OID as node's custom attribute, and then use it in script DCI. For example:

HOOK::ConfigurationPoll:

oids = %( ".1.3.6.1.4.1.41112.1.4.1.1.4.1", ".1.3.6.1.4.1.41112.1.3.1.1.5.1", ".1.3.6.1.4.1.14988.1.1.1.8.1.6.1" );
snmp = $node->createSNMPTransport();
if (snmp != null)
{
   for(oid : oids)
   {
      if (SNMPGetValue(snmp, oid) != null)  // You may use more sophisticated checks here if needed
      {
          selectedOID = oid;
          break;
      }
   }
}
SetCustomAttribute($node, "WirelessCenterFrequencyOID", selectedOID);


and script DCI:

oid = GetCustomAttribute($node, "WirelessCenterFrequencyOID");
if (oid == null)
   return null;  // No OID selected, mark as unsupported
snmp = $node->createSNMPTransport();
if (snmp == null)
   abort;
return SNMPGetValue(snmp, oid);

Наша сессия вопросов и ответов с разработчиками начнется сегодня в 14:00 EET. Для желающих подключиться и поучаствовать ссылка на конференцию:

It could be limitation of framework we are using that cause scrolling reset on each refresh. But somebody from the team will check.

Hi,

does Mikrotik switch support LLDP (that should allow NetXMS server to find connection between ProCurve and Mikrotik). DOes NetXMS server see correct FDB on Mikrotik switch? You can check that by right-click on it, and select Topology -> Forwarding database.
What is output f manual topology poll for both ProCurve and Mikrotik?

Hi,

you should pass IP address of the node you are pinging to ping command. Try

ping %a

as command (%a will be expanded to primary IP address of the node where you start object tool).

I see two options here:

1. Use regular expression for DCI matching in summary table to match all possible OID options. This will work only for summary tables though.

2. Create script DCI that will request correct OID depending on device type. For example:


oid = ".1.3.6.1.2.1.1.1.0";
snmp = $node->createSNMPTransport();
if (snmp == null)
   abort;
return SNMPGetValue(snmp, oid);


You can replace direct OID assignment in first line with actual logic for selecting correct OID.
