Hi all,
we have Hobbit 4.2.0 up and running (very well!) and we have BBWin client installed on our Windows servers. We started to install hobbit client on our AIX server (AIX 5.2) using this pre-built package http://rpm.razorsedge.org/aix-5.2/RE/ppc/hobbit-client-4.2.0-4.aix5.2.re .ppc.rpm and it works fine. But I noticed different memory reporting between AIX topas command and Hobbit web page, as follows
=== Topas output ===
Real,MB 8191 % Comp 49.3 % Noncomp 51.6 % Client 51.8
PAGING SPACE Size,MB 7680 % Used 20.5 % Free 79.4
=== Hobbit web output ===
Memory Used Total Percentage green Physical 8189M 8192M 99% green Swap 1612M 7680M 20%
While Total memory (8192MB) and Swap (7680MB, 20%) values are correct, reported Physical memory value is incorrect. Right value is % Comp 49.3 NOT 99%.
Is there anything I can change to have the right value?
Regards.

Hi
AFAIK, AIX uses (by default) a lot of memory for file caching, so you end up using ~100% of your physical memory.
Try running this :
/usr/samples/kernel/vmo -a | grep perm%
maxperm% = 40
minperm% = 20This means that 40% of your memory can (and often, is) be used for file caching.
vmo is available under AIX 5.2/5.3, you can use vmtune under AIX 5.1

Is there anything I can change to have the right value? I depends on what you want to plot. AIX will always put as much as possible unused programs in the swap and use all available memory for file system cache. So swap is never 0% and memory is always 100%.
We have plans to deploy hobbit to all are customers (+100 AIX boxes). I also have plans to tune the hobbit client and server for AIX monitoring and write all kind of extra scripts (I already have scripts to monitor error report, lvm, printers, cupsd, HA/CMP, CPU, ...). These scripts are written for bb and create graphs. I have to port them to hobbit.
If you are interested in AIX specific stuff, let ne know. An extra debugger is always welcome ;)

Hello Stef,
I'm really interested with your extra scripts. Actually, I'm running some scripts from deadcat.au like bb-errpt, bb-lvm, etc... Are your scripts similar or do you write your own from scratch ? In anyway, if you could send me some of them, I will do my best to help you in debugging. Thanks for sharing ! Regards,
Thomas

It is possible that this "project" is scheduled for next year, so you will have to wait a while.
One of things I did when I wrote the scripts and I was using BigBrother, is changing larrd so I can create graphs on the fly. Basically, it is like ncv, but I used "hidden html" to specify the graphs parameters: <!--RRD EBCT EBCT1 20585056.0512--> I will have to change that mechanisme too.

Thanks for reply. I will wait until next year, no problem ! Snicerly,
Thomas

I'll help debug if and when you need it :)
I've got some home grown stuff also, ranging from errpt to HA, and some deadcat stuff, but am always looking for alternatives.

I'm going to clean up my messy bb code and replace it with clean hobbit code ;) Wih hobbit, I have CPU, memory, disk i/o, power5, ... graphs. All AIX specific. I want the same with hobbit. You can send me your scripts, if you want, maybe I can use them too.
A few days ago, I installed twiki on my web-server. Hobbit is one of the webs I just added ;)
