The Splunk bucketing option allows you to group events into discreet buckets of information for better analysis. For example, the number of events returned from the indexed data might be overwhelming, so it makes more sense to group or bucket them by a span (or a time range) of time (seconds, minutes, hours, days, months, or even subseconds).
We can use the following example to illustrate this point:
tm1* error | stats count(_raw) by _time source
Notice the generated output:
Here is an additional example:
tm1* error | bucket _time span=5d | stats count(_raw) by _time source
The output obtained is as follows:
Similar to the chart command, timechart is a reporting command for creating time series charts with a corresponding table of statistics. As discussed earlier, timechart always generates a _time x-axis (while with chart, you are able to set your own x-axis for your chart visualization). This is an important difference as the following commands...
