[nsp] Monitor GSR Line Card CPU

[Lars Erik Gullerud]

OK, since I know for a fact that our monitoring system does what you are
looking for, I had to dig through some code to see how it is actually
implemented, since I didn't write the code in the first place. 

The various branches under "1.3.6.1.4.1.9.9.109.1.1.1.1" gives you all
the info you need about all the linecards. First we walk the following
three branches:

1.3.6.1.4.1.9.9.109.1.1.1.1.3
1.3.6.1.4.1.9.9.109.1.1.1.1.4
1.3.6.1.4.1.9.9.109.1.1.1.1.5

These contain 5 second, 1 minute and 5 minute stats for all the CPU's in
the system. Then, to figure out which is which, we do the following.

Walk "1.3.6.1.4.1.9.9.109.1.1.1.1.2", which lists all the CPU's in the
system, and showing their corresponding entPhysicalIndex. These indexes
can then be looked up in the ENTITY-MIB. For instance, in one of my
GSR's, the above walk returns:

2.1 = 30
2.2 = 51
2.3 = 56
2.5 = 40
2.6 = 49
2.7 = 61

To find out what these cards are and what slot they are in, we fetch the
info from the ENTITY-MIB under "1.3.6.1.2.1.47.1.1.1.1.2" and
"1.3.6.1.2.1.47.1.1.1.1.7". E.g. to find the last card described above
(with entPhysicalIndex 61), we fetch:

1.3.6.1.2.1.47.1.1.1.1.2.61 = "3 port Gigabit Ethernet, HwVer#: 2.0,
SwVer#: 12.0"

1.3.6.1.2.1.47.1.1.1.1.7.61 = "slot 5"

And there you go. 3-port GigE card in Slot 5 is index 7 in the 5 sec, 1
min and 5 min values we retrieved. Of course, we don't look up the
ENTITY-MIB every time, only during discovery/rediscovery of the device.
