| 13 | bootchartd is commonly used to profile the boot process
|
|---|
| 14 | for the purpose of speeding it up. In this case, it is started
|
|---|
| 15 | by the kernel as the init process. This is configured by adding
|
|---|
| 16 | the init=/sbin/bootchartd option to the kernel command line.
|
|---|
| 17 |
|
|---|
| 18 | It can also be used to monitor the resource usage of a specific
|
|---|
| 19 | application or the running system in general. In this case,
|
|---|
| 20 | bootchartd is started interactively by running bootchartd start
|
|---|
| 21 | and stopped using bootchartd stop.
