heh. You're probably also familiar with the extremely popular Lytec Medical Billing software. Current version was just released on Febuary 9, 2015. My first jump into patient scheduling software programing was in 1996 using FoxPro 2.6a. The Rushmore database technology was awesomely quick for what was also available at the time!
Back to topic, The WhosOnline page will show as many users as your database can generate. The time is determined by the "Who's Online Settings" at:
Control Panel > Display Options > Who's Online Options > Who's Online Timeframe
Users will be listed as online if they have visited within this timeframe (in minutes).
60 = 1 hour
720 = 12 hours
1440 = 24 hours
Most sites set this to "120" -- two hours. But you can set it to whatever you need. And obviously, the users online goes up based on time of day, day of week and many sites are even seasonal, so the month also plays a great part. Install a site analytics tracking software and start monitoring.
If you're already creating "Electronic Health Records" software, you're probably also aware of how important (and incredibly valuable) keeping statistics on most everything is. I am absolutely shocked that you haven't been tracking this type of information since day one -- even if for the simple reasons of justifying a program's viability, a research project, a federal grant or for just simply justifying your paycheck.
