NetXMS Support Forum

Hi,

I have to get more specific information to investigate it further. Can you please provide MAC address of a computer which is not shown as connected to the switch and result of Topology -> Switch forwarding database command on the switch?

Best regards,

Hi,

try to omit cmd /c and use only

sc \\pmtbackup start spooler

as command. Also, make sure that Windows user NetXMS server service runs under (Local System by default) has access to Service manager on server you try to start service on.

Hi,

yes, you need filtering script for that. To match events from 9:00 to 16:59 (both inclusive) it could look like following:


now = localtime();
return (now->hour >= 9) && (now->hour < 17);

Try to change chart interval to something larger, like 1 week - will you see something? Check that you have correct time zone settings on server and workstation.

Можно, хотя и довольно длинным путем. Сначала надо сделать события из трапов (одно или несколько, не так важно) и вытащить данные в параметры события, а затем в правилах обработки событий вызвать NXSL скрипт, в котором функцией PushDCIData создать новое значение соответствующего push DCI.

Я добавил метод

virtual void getInterfaceState(SNMP_Transport *snmp, StringMap *attributes, DriverData *driverData, UINT32 ifIndex, InterfaceAdminState *adminState, InterfaceOperState *operState);

в класс NetworkDeviceDriver. Можно его переопределить и реализовать собственную логику опросов интерфейсов.

I mean you can monitor OID you are monitoring now, just call it differently and use transformation script to return 0 when all APs are up. Or, you can delete transformation script at all and use script only for adding number of down APs into message (via %[] macro).

I've register a change request to use agent for DNS resolution for remote zones: https://dev.raden.solutions/issues/778. Should not be hard to implement.

Hi,

system will show "indirect" if more than one MAC address is seen on switch port - in this case server assumes that more than one computer is connected via some unmanaged switch. This often could happen if you have computers connected via IP phones.

Are you using zones or just set proxy for individual nodes?

the problem with your transformation script is that it's not linear - it will return 71 when everything is OK and then 1 or more when some APs are down. So diff will actually grow as more APs will go down. I would recommend to call DCI "number of down APs" and return 0 when all APs are up. That way it will be consistent and diff() > 0 will not be triggered when all APs comes back online.

Yes, that could happen if there was incorrect data in event processing policy. You have to manually fix or delete those rules.

Yes, nodes will be rediscovered - the only problem if you have configured some data collection on them - all collected data will be lost. If this is not the case then you can just delete them with subnets.

Hi,

you can set threshold not on absolute value, but on difference with previous value, and generate event if it is less then 0 (i.e, some APs goes down). Then you can achieve what you want with two thresholds: diff threshold will generate new alarms on each change, and recover on next poll - but you should ignore recover event. Another threshold could be set as now, but used only for recover event.

Not with configuration - but server could be changed to use proxy agent for name resolution. But can you confirm that this is the case (i.e. DNS name of node behind proxy cannot be resolved correctly from server)?
