pysysbot is capable to display details about the system it is running on. If you don’t want or can stay connected through SSH all the time this is an easy way to get information about the remote system. If you are interested in statistics collectd or munin is a better choice.
If you send “help” the bot will tell you what you can get from him:
This is a simple Jabber bot that can show you some details and
information of the machine it is running on.
