Hello all, I've read a number of articles around on snmp and have a fundamental theory going as to how this works at a macro level but need some confirmation. Any assistance will be greatly appreciated.
As I understand it the part of the OID that is returned depends on its existence in the MIB. I examined a couple of MIB's and none of them do more than relate an explanation of what the particular OID provides and in what format it provides it. (along with name resolution for the OID) What I expected was some way of describing to the snmpd agent where to get the value to return. Since I did not find it there I have the following assumption: The snmpd agent is written to pull data on a finite amount of data for N number of devices hard coded into the binary. The MIB simply denotes the values to offer up to remote collectors. If this is correct, I see there are a number of MIB files present by default on Fedora which I'm using. I don't know if one of these MIB files has every possible item that can be checked, changed and or reported by the development in the net-snmpd agent. If there are other devices that those MIB's don't describe, how would I know I can use them and what their syntax would be? Is there some list published for every possible value the snmpd agent is hard coded to be able to query along with their MIB entry? If I wanted the snmpd agent that comes with Fedora to pull some value from some unique location of my choosing I would have to write my own snmpd agent or use the snmpd.conf file to point to a script that gathers the info I want? Also, if one of the MIB's in the mib folder by default for net-snmpd does contain every possible value snmpd is hard coded to check, which one is it? I hope this makes sense and look forward to some any help... Larry ------------------------------------------------------------------------------ Check out the new SourceForge.net Marketplace.
