<![CDATA[NETXMS lost all MAC addresses]]>Hello there,

I´m using V.2.19 with Netxms client on monitored servers.
After a specific date, I noticed that Netxms server isn´t collecting any client DCI. only client status.
I noticed then that all my Mac addresses for the nics under each node were gone.
the problem can be simply solved deleting the node and adding it again. but this way I loose my history because it creates another object ID.

Have anybody ever had a problem like this ?

Right now I´m seeing the tables from the database, looking for the field where it stores tme MAC addresses, I guess if I change it there, it will work again.

Anyway, if anyone have a better idea, please post .

Only upgrading the server didn´t solve the problem. MAC addresses were still 00.00.00.00....

I had to upgrade the NETXMSclient on the machine reporting blank MAC address. And worked fine.
Seems to be a problem on the client, because even if you manually try to pool "Status", "Configuration" or the new option "interface names" doesn´t work.
Also, the network interface were appearing as "lan0" and after solving the problem, it detected as "local area connection"

I hope these information help you on next releases.

PS: I´m still with the problem on SNMP devices. I´ll take look and try to find out an answer.

Thanks !

Looks like poller threads inside NetXMS server hangs for some reason. Loss of MAC address configuration is just a consequence, not the source of a problem. Could you please try to upgrade to 0.2.20 - some bugs of 0.2.19 are solved in it - and tell if this helps or not.

Best regards,
Victor

I reinstalled the client and pooled the configuration.

Well, it worked with the workstations. what about the SNMP devices ? routers doesn´t have a client.
still working on it.
