It displays the plain events present in the index.
For Example: Say you write a search as
index=myindex earliest=-1d@d latest=-0d@d For this, the Events Tab lists all the events present in the index
myindex for previous day.
myindex can be a raw index or a summary index.
For the above search, the Statistics tab doesn't display any reporting data since you have not used any reporting commands. The Statistics tab will contain a message:
"Your search isn't generating any statistic or visualization results. Here are some possible ways to get results."
This tab depicts search results as report result tables. For the same search that is used in the Events tab example, if we add some reporting search command, say for example:
index=myindex earliest=-1d@d latest=-0d@d | stats count as Count by ClientIP then the Statistics tab contains data for this search with two columns ClientIP and Count.
Assume that your index has 1000 log events and the unique ClientIP count in those 1000 log lines is 10. Then the Events tab will contain 1000 entries and the tab heading will be
Events(1000), the Statistics tab will contain 10 entries and the tab heading will be
One more point is: whether data gets displayed under Events tab or not depends on the search mode.
