System information

Create RRD
I had been thinking about making this config options and putting the formulas in the code.
NMIS Command Line
simple script to provide status of nodes and basic info like summary.pl but commandline oriented.
Thresholds
Put the threshold code seperate for just using in nmis.pl
HOST MIB
Add support for HOST-MIB, then get CPU and MEM working dynamically, get DISK mapping working for disk free and usage stuff.
Add a control file like the interface.dat which maps CPU and MEM and DISK, also tracks inventory changes.
Eric,
Yep, this was used pre Event Policy table, which is when I figured the event
policy should be used. I think this is only used by nmiscgi.pl and looks
redundant. If an event exist for a node, then just get the level from the
event state table. Should be a small patch.

Keith

Subject: [nmis_users] eventlevel
Keith - I am not sure why the subroutine eventlevel in NMIS.pm
appears to overule the event levels as defined in the policy table -
is there a good reason for this, have I misread the code, or was
this something to get the project up and running out of the box ?

Interface Speeds and SNMP Spikes
Yes and No, best handled in RRD but not so easy, sort of need to handle in NMIS and RRD, ie if NMIS detects a reset (which it does by monitoring sysuptime),
checks last RRD value and sets current interface poll to 0 which should reset the RRD and remove the spike.
Nasty little SNMP! I think the problem is when the SNMP counter gets reset and RRD doesn't know how to deal with it, ie last collect was 10000, now 100 and
it has a small spike as it thinks the counter has wrapped.
Limiting the CDEF to the speed of the link is a good idea, but for some interface types it is not accurate, ie for ATM or Frame Relay PVC which have a burst
capability. I will add this to the TODO list and ponder it a little more, will have to put some code in to handle interface types and speed of primary interface.
