[HOWTO] aix 5.3 quickie howto

[shanekennedy]

just set up aix host as cacti device & thought i'd share info. my cacti server is on linux

compiled perl 5.8.8 w/ ibm C compiler
used compiled perl to compile net-snmp 5.4.1 using sed & grep rpms from
http://www-03.ibm.com/systems/p/os/aix/linux/toolbox/download.html
set up perl w/ "configure --enable-as-needed --without-kmem-usage"

started snmp w/ "/usr/local/sbin/snmpd -A -r"




created /sbin/snmp-cacti script containing:

#!/bin/ksh

if (( `ps -ef | grep snmp-cacti | wc -l` > 20 )) then
exit 1
fi

case $1 in

[madunix]

any feedback about this script before i use it ...

[rony]

I like what I see!

The only thing is, for example, where I work, we will not install net-snmp. So, I wonder if the AIX SNMP implementation supports external scripts? I think I will have more luck playing the lottery...

[madunix]

I have a linux server RHEL5 64bit running cacti, I am in process to capture the snmp data of my AIX clients, any help how to proceed with this.


Thanks

It's hard to hide my disappointment regarding Cacti and AIX. I've chunked through everything in the Forum that a search for AIX+SNMP provided... just several big piles of disorganized mutterings. As often as not, it is unclear whether the posters are working in the context of net-SNMP or the native AIX SNMP cruft.

Have things changed significantly since 2005 for the native AIX SNMP agent? Should it be avoided altogether, if net-SNMP is an option?

[rony]

Anything with my name on it is with concern to the AIX SNMP Agent.

To be honest, if you can use the net-snmp agent, do it. The AIX agent is a convoluted piece of crap.

[andyfb]

With which graph templates do you monitor the results?
Can you attach them, please?

Thanks!
