Hi,
I changed hobbitgraph.cfg so it created to extra graphs: one for Access Virtual Memory and one for the free list. See http://www.docum.org/twiki/bin/view/Hobbit/AixTips Henrik, can you add these graph definitions ?
I also patched the hobbit server so it monitors the Access Virtual Memory on AIX:
diff hobbit-4.2.0/hobbitd/client/aix.c hobbit-4.2.0.ori/hobbitd/client/aix.c 73c73 < long memphystotal, memphysused, memphysfree, memactused, memswaptotal, memswappct;
long memphystotal, memphysused, memphysfree, memswaptotal,
memswappct; 80d79 < if (sscanf(freememstr, "%*d %*d %ld", &memactused) == 1) memactused /= 256; 88c87 < memphystotal, (memphystotal - memphysfree), memactused,
memphystotal, (memphystotal -
memphysfree), -1,
Henrik : The only problem is that Total for the line Actual is always the
amount of Physical Memory. But this should be Physical Memory + Swap Memory.
At least, this is for AIX, but I think this is for other os'es as well. I
think this is a bug.
The problem is that Actual can be > 100%. So, I had to change ./hobbitd/rrd/do_memory.c and remove the > 100% to get some graphs: //if ((actval >= 0) && (actval <= 100)) { if (actval >= 0 ) { sprintf(rrdfn, "memory.actual.rrd");

Henrik (and others), any comments on this post ?

Hello,
I know this has been brought up before, but I was wondering if any has had any luck. Has any been able to integrate the SAR like capability of LARRD from Big Brother into Hobbit? Thanks!
Please disregard this message, sorry for the duplicate.

The problem is that Actual can be > 100%.
The problem with using Accessed Virtual Memory as monitoring for memory usage is that this can be more then 100%. This numbers is inflated on AIX. I still don't know how this can, but AIX does pre-allocation for swap. So some parts of memory have a copy in cache and are counted twice.
Anyhow, this number is still important to monitor. But some special care is needed. First of all
- Actual can be > 100%
- the maximum for Actual is amount of memory + swap (currently this is only the amount for memory)
- for AIX, the warning and error thresholds for Actual needs to set higher because this number is bigger then you would normally expected.
See my first post for some patches.

I changed hobbitgraph.cfg so it created to extra graphs: one for Access Virtual Memory and one for the free list. See http://www.docum.org/twiki/bin/view/Hobbit/AixTips Henrik, can you add these graph definitions ? Henrik, can you add these to hobbitgraph.cfg: [vmstat-avm] TITLE Memory Accessed Virtual Memory YAXIS Size kB -b 1024 DEF:avm=vmstat.rrd:mem_avm:AVERAGE CDEF:sw=avm,4048,* LINE2:sw#00CC00: GPRINT:sw:LAST:Accessed Virtual Memory \: %5.1lf%s (cur) GPRINT:sw:MAX: \: %5.1lf%s (max) GPRINT:sw:MIN: \: %5.1lf%s (min) GPRINT:sw:AVERAGE: \: %5.1lf%s (avg)\n
