Port bootchart2 to PostmarketOS, with three patches: 1. Modification of /etc/bootchartd.conf so that the collector will stop after sshd has started. 2. Python 3.8 compatibility 3. Disable the interactive mode of pybootchartgui. Use bootchart2 to profile system boot or a running system. 1. Add the bootchart2 package to your device. 2. Add the following kernel command line parameters: initcall_debug printk.time=y quiet 3. To profile system boot a. add the following kernel command line parameter: PMOS_BOOTCHART2. This parameter causes mkinitfs to start /sbin/bootchartd instead of /sbin/init. /sbin/bootchartd then starts /sbin/init. b. (optional) modify EXIT_PROC in /etc/bootchartd.conf to define when the collector is to stop. c. Boot the system. Approximately 20 seconds after sshd starts (if using the default value of EXIT_PROC), the collector will exit. 4. To profile a running system a. use the command '/sbin/bootchartd start' (as root) to start profiling b. use the command '/sbin/bootchartd stop' (as root) to stop profiling 5. When the collector exits, /usr/bin/pybootchartgui will create a visualization in /var/log/bootchart.png. |
