NetXMS Support Forum

В версии 1.2.10 добавил две новые вкладки для подсетей - список узлов и карта адресов. Занятыми адресами считаются те, для которых есть обьект в NetXMS, т.е. корректные данные будут только при включенном network discovery.

Попробуйте агента версии 1.2.10 - я исправил обработку /proc/drbd

Hi!

Bug should be fixed. We have uploaded updated installers, Please download updated version and reinstall.

Hi!

It's not possible yet. All you can do is to setup two thresholds and use filtering script in event processing policy to block events at specific time of the day. However, soon (I plan for 1.2.11 so far) you'll be able to create thresholds as NXSL scripts, then it will be much easier.

Hi!

I've changed the drbd.cpp (protocol version should also work as expected). These changes are included in 1.2.10 release. Thank you for fixing it!

Best regards,

*PING - это начало новой секции конфига. ActionShellExec должен быть в основной секции, вот так:


MasterServers = trampampam.ru
ConfigIncludeDir = C:\NetXMS\etc\nxagentd.conf.d
logFile = C:\NetXMS\var\log.txt
FileStore = C:\NetXMS\var
SubAgent = ecs.nsm
SubAgent = ping.nsm
SubAgent = logwatch.nsm
SubAgent = portcheck.nsm
SubAgent = winperf.nsm
SubAgent = wmi.nsm
SubAgent = ups.nsm

ActionShellExec = ResroreWinVPN:C:\Windows\system32\rasdial.exe $1 $2 $3

*PING
Timeout = 1000
PacketRate = 12
Target = 10.0.0.1:target_1


Hi!

1.2.10 should be released today.

Hi!

You can create new internal DCI with custom schedule to run once per month and either read current value of cumulative counter in transformation script. The tricky part is timing to ensure that monthly DCI runs before cumulative counter resets at month change. Alternative option could be storing value temporarily in node's custom parameters - when cumulative counter resets, it stores it's current value into some custom attribute, and then monthly DCI reads it.

Best regards,

You returning value of original DCI in your transformation script, but if you want cumulative counter, you should return sum of current value of your dummy DCI and current value of original DCI, something like

GetDCIValue($node, dci->id) + GetDCIValue($node, $dci->id)

($dci refers to current DCI being processed).

And to reset the counter - check if last poll time for your dummy DCI is in different month, and return 0 in that case, like this:

if (strftime("%m", $dci->lastPollTime) < strftime("%m", time()))
   return 0;

This filtering script checks that absolute value for given OID is 0. If you have non-zero value which is not changing over time, OID will pass filter but you will still get 0 as delta value. If you want to filter out any non-changing values, you should get two samples and check delta, like this:


snmp = CreateSNMPTransport($node);
v1 = SNMPGetValue(snmp, ".1.3.6.1.2.1.2.2.1.16." . $1);
sleep(10000);  // sleep for 10 seconds
v2 = SNMPGetValue(snmp, ".1.3.6.1.2.1.2.2.1.16." . $1);
return (v2 - v1) != 0;


Of course, practical use of such method is questionable and depends on your goals - you will either miss slowly changing OIDs if sleep interval is too small or make configuration polling extremely long if you have lot of instances and long sleep interval.

Victor

Hi!

This could happen if you have large network, autodiscovery is on, and lot of hosts/devices did not respond to ping and SNMP (usually because of firewall). If this is the case, you don't have to worry - eventually queue will go down. The only drawback is that network discovery will take much longer type. You can speed up discovery process by allowing access from NetXMS server where needed and/or using address filters for network discovery to skip unneded address ranges.

Hi!

SNMP OID used for data collection is in fact DCI name, and so it is available as first event parameter via macro %1 or variable $1 in filtering scripts.

Victor

Hi!

I've changed sorting in last values view to be data type aware. This fix will be part of 1.2.10 release.

Вот он.
