|
|
|
- Print a tree of the time-critical chain of units:
|
|
|
|
`systemd-analyze critical-chain`
|
|
|
|
- Create an SVG file showing when each system service started, highlighting the time that they spent on initialization:
|
|
|
|
`systemd-analyze plot > {{path/to/file.svg}}`
|
|
|
|
- Plot a dependency graph and convert it to an SVG file:
|
|
|
|
`systemd-analyze dot | dot -T{{svg}} > {{path/to/file.svg}}`
|
|
|
|
- Show security scores of running units:
|
