Description of the Session Activity Chart for a SQL

This image is a screen capture of the Activity chart for a SQL. The x-axis shows the dates from 27 February to 29 March 2018. The y-axis shows the Active Sessions, in increments of 0.02, from 0.00 to 0.10.

The category 'I/O Wait' is indicated by blue color, 'CPU' wait is indicated by green color, and 'Other Wait' is indicated by orange color. The chart shows that the SQL spent a major portion of its idle time in the 'Other Wait' category, between 23 and 28 March 2018 and comparatively smaller portions in the ‘CPU’ and ‘I/O’ categories during the same period.
