Можно написать data collection script, который в цикле будет опрашивать ноды и возвращать первое успешно полученное значение. Выглядеть может например так:


nodes = %("node1", "node2", "node3");
foreach(n : nodes)
{
   node = FindNodeObject($node, n);
   if (node != null)
   {
      snmp = CreateSNMPTransport(node);
      if (snmp != null)
      {
         value = SNMPGetValue(snmp, ".1.3.6.1.2.1.1.1.0");  // put your OID here - you can also pass OID as script parameter
         if (value != null)
            return value;  // got response
      }
   }
}
return "ERROR";   // error indication


Соответственно DCI на массиве будет с типом Script и в качестве имени - скрипт из библиотеки.

"connection refused" означает что веб интерфейс не может к netxms серверу подключится. NetXMS сервер на той-же машине? Запущен?

Hi,

if you have Linux installation, can you please run it under gdb?

Commands would be like this:

gdb /path/to/netxmsd

will show (gdb) prompt, then

run -D5

server will run in foreground. When crash will happen, (gdb) prompt will be shown again. Type

bt

and send me an output.

Hi!

You may need to build NetXMS in UNICODE mode (by adding --enable-unicode to configure) or set proper code page in netxmsd.conf (CodePage parameter).

Hi,

Debian 7 packages should work on Ubuntu, and so you can use repository for Debian 7. You can just add

deb https://www.netxms.org/apt wheezy main

to /etc/apt/sources.list, then run

apt-get update
apt-get install netxms-agent

Should work fine.

Victor

Hi!

Do you use precompiled binaries or you compile NetXMS on Ubunto from sources?

in 'Performance Tab' 'Title' I can't use the macro {instance-name}. Is it not implemented, a bug or my error in reasoning?

You can only use {instance} macro there. But actually you'll got instance name with that macro. Long explanation is following:

{instance} and {instance-name} macros in DCI name and description expanded during instance discovery process. There is "instance" field in each DCI (you can see it's value on "Thresholds" tab) - you can edit it freely for ordinary DCIs but it is populated automatically for DCIs created by instance discovery, and it is set to instance name. Macro {instance} in performance tab configuration expanded when you open performance tab, and value of "instance" attribute of appropriate DCI is used.

Both macros was created when there was only {instance} in instance discovery and it was making sense. Now with introduction of {instance-name} macro it becomes counter-intuitive. I probably can add {instance-name} macro to performance tab just to make it compatible - but still it will not allow to get actual instance value (although I double somebody will need it in graph title).

Hi,

check server configuration variable SyncNodeNamesWithDNS - it must be set to 0 to avoid node names re-sync with DNS.

Hi,

no, we do not support time filtered MIBs. I'll add this as feature request.

So it's a bug in SNMP agent on switch then. The only workaround so far is to disable topology poll on that node and restart NetXMS server.

Victor

Hi,

interesting is that I don't see "Finished topology poll" message for that node. This may indicate that server is stuck within topology poller for some reason. Can you please run snmp walk from command line on this node on OID .1.3.6.1.2.1.17.7.1.4.2.1.4? I suspect that walk may cycle for some reason thus forming infinite loop.

Hi,

you are using wrong configuration parameters. Correct will be

ID = NTS8
Name = 172.29.10.149:1549/NTS8
Username= apps
Password = apps

ID is an arbitrary string. You will use it in parameters, like this:

Oracle.Cursors.Count(NTS8)

See Oracle subagent documentation for more information: https://www.netxms.org/documentation/adminguide/subagents.html#oracle

Hi,

in version 1.2.7 we start using finction inet_pton which seems to be defined only in SUNW_1.3.1 version of libxnet. That's the only dependency on this version. I'll check how it's usage can be avoided.

Hi,

agent uses Windows performance counters for accessing CPU usage and uptime. Check that winperf subagent is loaded and do not report any errors on startup. It is possible that performance counters are corrupted or PDH is disabled altogether.

Can somebody provide me SNMP access to modern HP/H3C switch?
