Octoboard collects data from cloud applications using publicly available APIs. How much and how long data is stored depends on cloud applications that you connect to.
Applications provide data for Octoboard differently. Some offer a lot of data, others are more restrictive.
Google Analytics, for example, would offer a lot of historical data and Octoboard will query many months back.
Other applications such as Twitter, Youtube or Instagram, for example, would not return historical data for some parameters at all. For such applications, Octoboard will collect data every day and will build it up over time. The longer you use Octoboard, the more data you will see over time.
This is how Google Analytics widgets look from day one (note charts and graphs filled with data).
And here is Twitter Engagement metrics - they are not available initially and will be accumulated by Octoboard over time - see “OVERVIEW” graph as an example.
Over time you will get data collected and stored in the system. Just keep using Octoboard.
