SNMP based template for memory / swap usage on a Unix host

[jfxura]

Thnx phalek. That worked.

Wish i'd read the entire thread before posting!

Hello world (the first message on this board, I guess).

Was happen also to my installation the CDEF was incorrect and I needed to adjuct the definition, as suggested by phalek.

My installation is 0.8.7e, installed from fresh. Maybe it's need to export the template I have for avoid the same error to someone?

Hello!

I have imported the template, but I only have the "Localhost - Memory - Free" data template:
<path_rra>/localhost_mem_buffers_3.rrd

Is there any patch for the other fields?

All is nice but it will very nice if we can add memory usage with percentage.

I added percentage to the graph by creating my own CDEF. I used the Memory Used (Linux) CDEF.
I called it "Percentage Memory Used (Linux)
cdef=d,c,-,b,-,a,-,1024,*,d,/,10,/

Item #1......Another CDEF: Memory Used (Linux)
Item #2......Custom String: d
Item #3......Operator: /
Item #4......Custom String: 10
Item #5......Operator: /

*****************************
It doesn't get graphed but it shows up in the list of values..
My ONLY problem is trying to create a THOLD against the percentage. Anyone?

Excellent template. Used in cacti 0.8.8.a with some minor correction suggested by phalek.

CDEF:cdefa=d,c,-,b,-,a,-,1024,* \

Seems to be quite good template. However I seem to be getting only buffer and free working. Any idea how come the others are either 0 or "nan"?

Hey guys!

the memory template works fine on hosts with a total of up to 16GB RAM (I guess).

But I have 3 Linux Hosts and each of them has 256GB RAM.

the template isn't capable to get the total, used and cached values.

It's just -nan

is there a solution?

PS: My CDEFs are CDEF:cdefa=d,c,-,b,-,a,-,1024,* \
