I just upgraded my Linux Debian server to release 7.2, and it seems that the insight agents for debian are only for the squeeze version (6.X) and not the wheezy (7.X) one.
For installing the packages, it needs the squeezy repositories, except for the hponcfg package.
The hpasm is able to get more information now than in the previous version of Debian (like the serial number and going into the IML), but I did not try the snmp, as the hp-snmp-agents depends on the package libperl 6.10 (if I remember correctly), and the wheezy version has the libperl 6.14.
