Create charts that are not (necessarily) time-based
The chart command
timechart command, which uses the
_time default field as the x-axis, charts created with the
chart command use an arbitrary field as the x-axis. With the chart command, you use the
over keyword to determine what field takes the x-axis.
Example 1: Use web access data to show you the average count of unique visitors over each weekday.
sourcetype=access_* | chart avg(clientip) over date_wday
One of the options you have is to split the data by another field, meaning that each distinct value of the "split by" field is a separate series in the chart. If your search includes a "split by" clause, place the
over clause before the "split by" clause.
The following report generates a chart showing the sum of kilobytes processed by each
clientip within a given timeframe, split by
host. The finished chart shows the
bytes value taking the y-axis while
clientip takes the x-axis. The delay value is broken out by host. After you run this search, format the report as a stacked bar chart.
sourcetype=access_* | chart sum(bytes) over clientip by host
Example 2: Create a stacked bar chart that splits out the http and https requests hitting your servers.
To do this, first create
ssl_type, a search-time field extraction that contains the inbound port number or the incoming URL request, assuming that it is logged. The finished search would look like this:
sourcetype=access_* | chart count over ssl_type
After you run the search, format the results as a stacked bar chart.
