Re: SNMP version to work Load average

If you've got the software installed, why not simply query
the agent and see what it returns for these objects?

If the documentation says that a particular module isn't
supported on a given architecture, then it probably won't
work. But if you've got the software up and running, it
should be simple enough to check for yourself.



> By the way, how do I configure Load average?

If all you want is to retrieve the current load average figures,
you don't need to configure anything. The laTable will report
the 1-min, 5-min and 15-minute load averages automatically.

> snmpd.conf man page shows it:
> load MAX1 [MAX5 [MAX15]]

That directive is used to set the maximum thresholds.
A load higher than these values indicates an over-busy system.

> Does the instruction understand only the frequency to check the load?

These three load averages are standard figures, calculated within
the Unix kernel. The Net-SNMP agent simply reports the current
value(s), whenever the relevant objects are queried.
The details of actually calculating these values are buried deep
in the kernel, and is not something that the agent has any influence
over.

Eh? What are you talking about?
The load average indicates how busy the CPU is.
What does traffic or kB have to do with anything?

No - the load average does *not* show traffic.
It shows the CPU load.

> show numbers (in kB, MB, bytes units) or with words (low, normal, hi load)?

It is a number, not a words.
But the number is *not* kB, MB or any sort of bytes.

On a lightly-loaded, single CPU system, you would expect to see
a value somewhere between 0 and 1. (0=completely idle,
1=constantly processing, >1 = overloaded),

See http://en.wikipedia.org/wiki/Load_(computing)
for a more detailed explanation.
