Hi there,
I am just wondering how SNMP retrieve run-time system
parameters.
For example:
somebox$ snmpwalk -l authPriv -u me -A "somepassword"
localhost
will give output like this:
....
....
HOST-RESOURCES-MIB::hrDeviceDescr.768 = STRING:
GenuineIntel: Intel(R) Pentium(R) 4 CPU 2.40GHz
HOST-RESOURCES-MIB::hrDeviceDescr.1025 = STRING: network
interface lo
HOST-RESOURCES-MIB::hrDeviceDescr.1026 = STRING: network
interface eth0
HOST-RESOURCES-MIB::hrDeviceDescr.1280 = STRING:
HP_LaserJet_4000
HOST-RESOURCES-MIB::hrDeviceDescr.1536 = STRING: SAMSUNG
SP0802N
HOST-RESOURCES-MIB::hrDeviceDescr.1537 = STRING: GCR-8523B
HOST-RESOURCES-MIB::hrDeviceDescr.3072 = STRING: Guessing
that there's a floating point co-processor
[some process data]
[some network-related data]
etc.
.....
I know the daemon will get the default value for some of
those parameters from the corresponding MIB files but how
SNMP gets those run-time parameters(e.g process ID ,mem
usage) and if SNMP stores those to files where does it
store???
Any help is appreciated......Thanks!
