    I read the tutorial and I did not found the answer to the following:
    – my logger is able to present me Erlangs but for 15 min or 1 hour.
    I guess it is to have a better idea of peaks.

    Example:
    from 9 to 9h15: 0.2 erlang
    from 9h15 to 9h30: 0.3 erlang
    from 9h30 to 9h45: 0.1 erlang
    from 9h45 to 10: 0.4 erlang

    If i ask for the same data but grouped by hour, i get for 9h to 10 h a value that is not 1 erlang (the sum of the values above).

    How is this to handle?
    How to calculate in erlangs for periods not equal to an hour?

    Best regards and thanks for the help.

    from 9 to 9h15: 0.2 erlang means ckt/s occupied for 3 minutes in 15 minutes observation (Erlang is occupancy of circuit divided by observation period)

    from 9h15 to 9h30: 0.3 erlang means ckt/s busy for 5 minutes in 15 minutes

    from 9h30 to 9h45: 0.1 erlang means ckt/s busy for 1.5 min(90 sec)in 15 minutes

    from 9h45 to 10: 0.4 erlang means ckt/s busy for 6 minutes in 15 minutes.

    In one Hour duration occupancy comes to (3+5+1.5+6)min=15.5 min
    ie 15.5/60 around 0.25E in 1Hour
