SCREENSHOT 32) The query in InfluxQL language, which is sent to the InfluxDB.
Some of the values are replaced with their actual values such as “$__interval“, which is based on what time frame is selected – “Last 6 hours”. If $__interval is not set on the query manually, it is a good idea to use the mean() function in the query (as in the example above).
SCREENSHOT 33) The Data tab in Query Inspector shows real values from the queries in a table form.
Multiple values of the idle measurement are shown. These values mey be cross-checked with the values from the special files /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq.
SCREENSHOT 34) Modifying the opacity of the graph.
The graph lines look better. The user can experiment with different style values.
