You can find the context of charts by looking up the chart in either http://your.netdata:19999/netdata.conf or http://your.netdata:19999/api/v1/charts.

You can find how netdata interpreted the expressions by examining the alarm at http://your.netdata:19999/api/v1/alarms?all. For each expression, netdata will return the expression as given in its config file, and the same expression with additional parentheses added to indicate the evaluation flow of the expression.
