Many things are possible. But Glance might not be the best tool for creating medium or long term graphs. It is designed to be a sysadmin's tool, for getting a quick "what is happening right now" style view. The graphical mode of Glance, "gpm" can draw some graphs, but must be running in interactive mode for the entire time you want the graphs for, which is inconvenient.
You'll want something that runs in the background collecting data, and then uses that data to generate graphs, either at scheduled times (daily/weekly/monthly) or on demand.
For a "simple" solution, you might set up sar (see man sa1 and man sar for details) for automatic data collection, then use free software like kSar to produce graphs out of the collected data. sar is included in every HP-UX installation by default.
For an "advanced" solution, you might dedicate a server (a VM is fine) to collect data from all your servers using SNMP or whatever protocol is available, and to present a Web UI that can be used to access the graphs and zoom into any time interval that has data available. Cacti can do that. You can even set up multiple views and set up usernames & passwords so that if you have multiple customers, each customers can see only his/her own data. Cacti can be somewhat complex to set up, but it is *very* extensible. In the Cacti users forum, you can find many templates and extensions for Cacti, and if none of the existing templates are suitable to your requirements, it is not too hard to create your own.
Like kSar, Cacti is free software.
