Determines the number of bytes that this event internally uses
in disk storage for the values, not counting the bytes for
storing the field names. This does not include the RAM usage of
an event during a query, implying that aggregated events will
have a size of zero.

Search for Events by Size in Repository
Search for events of a certain size in a repository using eventSize() function
Query
logscale
eventSize()|_eventSize>10000
Introduction
The eventSize() function is used to search
for events depending on the internal disk storage usages. The
function augments the event data with the event size information.
Step-by-Step
Starting with the source repository events.
logscale
eventSize()
Determines the number of bytes that events internally use in disk
storage for the values (not counting the bytes for storing the field
names), and returns the results in a field named
_eventSize.
logscale
|_eventSize>10000
Searches for events that take up more than 10000 bytes in internal disk
storage usage. Notice that you cannot do a direct comparison, as the
function augments the event data with the event size information, rather
than returning data.
Event Result set.
Summary and Results
The query is used to get an overview of the disk storage usage of the
different events and in this example filter on the largest ones. A high
disk storage usage can cause performance issues, depending on the time
range.
Track Event Size Within a Repository
Calculate the event size and report the relative size statistics for each event using eventSize() function
Calculates the percentile() for the
eventSize field and determines
which filesize is above 50%,75%, and 90,99% of the overall event set,
then finds the maximum size for the specified field over a set of
events, and displays the returned results in a timechart.
Event Result set.
Summary and Results
The query is used to show how statistical information about events can
first be determined, and then converted into a graph that shows the
relative sizes.
