Time series with additional information
I'm assuming the displayed time series shows number of jobs submitted per 15 minute interval. 

Categorical features

Divide the time series per category. If the jobs can be divided into type1, type2, type3 then make a time series for each type and predict each series individually. So type1-time series has number of type1-jobs per 15 minute interval.

Continuous features

For continues features e.g time-to-do-job you can divide the jobs into categories of time00,time10, time20, time30 for jobs that take 0-9 minutes, 10-19 minutes, 20-29 minutes etc respectively. As before generate a time-series per division. 

Depending on how much data you have and how it is distributed you can make more groups or space them differently.
