I feel like I'm missing something. I have an evaluation install of NPM installed and it's polling a number of our routers. When I drill down to an interface, there are some decent graphs there that show me traffic over the past 1h, 12h, or 24hr.
That's great when I'm investigating a recent congestion issue, but often I want to see if the current traffic is out of norm for the circuit, which means a much longer timeline. So far, the only way I've discovered to view the longer histories is to click 'edit', change the zoom range, amount of historical data to load, and sample interval, and then submit. This is a time consuming process to switch back and forth, and I feel like I must be missing an easier way.
How do you view history further back than 24h?
