I’m viewing the graph on the custom test page. The data is being reported in via data message if that makes a difference.
OK. What I'm thinking as that the graph shown on a test page is always for a specific time period (I think 24 hours), and rrdgraph chooses an appropriate granularity for that time period. If it were showing a "year" graph, it would choose weekly samples to graph. If showing a "month" graph, then it'll choose hourly samples. It's not until it's asked to show a graph of perhaps less than 24 hours that it will show samples shorter than 5 minutes. I don't know the exact thresholds, but I think the principle applies.
Not sure what you mean by reducing the trends period?
Does your graph show on the trends page for the server? On the trends page, up the top is a form that lets you adjust the time period for the graphs on that page. If you changed the default 2-day graph period to something like 12 hours, you might start to see finer resolution.
Another option is to click on the magnifying glass next to the graph in the test page, then drag to zoom in on the most recent 8 hours, and see if you get 1-minute samples showing.
