I'm using in inventory system.sw.packages[] key to collect information about installed software. Such data are stored in "Software (full)" inventory field.
http://<zabbixserver>/hostinventoriesoverview.php?form_refresh=1&groupid=0&groupby=software_full

I see two problems:

• If inventory string is long it is hard to browse inventory view
• Aggregated string is used in URL in Host count column. If such string is long enough like in case browsing data collected over system.sw.packages[] clicking on "Host cont" web browser cannot display page with list of host ("Request-URI Too Large" error message is displayed)

We are using zabbix 2.2.5 but probably all versions of the zabbix are affected.
