Click the Visualize, we choose pie chart here. The default search matches all documents. Initially, a single “slice” encompasses the entire pie, and the default aggregation method is Count, we can change to sum or unit count.
- The count aggregation returns a raw count of the elements in the selected index pattern.
- The sum aggregation returns the total sum of a numeric field. Select a field from the drop-down.
- Unique Count
- The cardinality aggregation returns the number of unique values in a field. Select a field from the drop-down.
We need to divide the pie according to out standard, in my instance, I need to check how many syslog from host 192.168.90.3, how many from syslog.log file, how many from others source.
click the Split slices , then select Filters under the aggregation, I type 192.168.90.3, then click “Add Filter”, then type syslog.log, and click the Apply change button.
And you will see the pie chart similar to this:
Then click the save in the navigation bar, name it( I choose syslog_chart as the name) and click “Save”. This name can be used in Dashboards.
