I am Jairo Lopez and am currently working with Miracle Linux in Japan.
We have been working on getting the vfs.dev.read and vfs.dev.write agent keys working for AIX 6.1. We have implemented the number of bytes read and written to all the disks on an AIX machine and on particular hdiskX devices. The implementation relies on libperfstat to obtain the data.
Attached is our working patch the Zabbix 2.0.3 agent on AIX 6.1
We thank you for your time and would like to receive comments.
