7.7.1 Running the collectl Utility from the Command Line
The default action of this utility is to collect data at 10-second intervals and to display the data in ASCII
characters on the terminal screen. Example 7-1 shows the invocation and first record reported from the
collectl utility. The information has been edited to fit horizontally on the page.

The collectl utility provides alternate output formats:
• Use the --M 1 option to display the output in a single line for a more compressed and easier to read
format. Be aware that this option may not produce all the fields.
• Use the --oT option to timestamp the data.
• Use the --oD and --od options to provide two formats of a date and timestamp.
For a discussion of the options to the collectl utility and a description of its output, see collectl(1).
7.7.2 Running the collectl Utility as a Service
After it is enabled, the collectl utility can be run as a service. You can use the service command to
stop and start the collectl service. You can also obtain the current status of this service, as shown in
the following example:
# service collectl status
collectl (pid process_id) is running...
