Currently we are experiencing unknown statuses on server interfaces which are monitored by Orion NPM. We have different Linux OS installed on our servers such as cent, red hat, white box and etc.

An issue that we observed regarding this is that those servers whose OS are Cent 5 with no pre-installed snmp services are stable and monitored correctly by Orion NPM. But those who have lower versions like Cent 4, Red Hat 4, White Box 4 and etc which have pre-installed snmp are the ones who have unknown statuses monitored by Orion NPM.

We're quite confused regarding this issue, can anyone help us? Thanks...
