[systemd-devel] Fwd: [systemd-commits] Makefile.am src/bootchart - Make bootcharts go to the journal

[Kok, Auke-jan H]

FYI - this is a first pass to putting the bootcharts into the journal,
exactly as coredump does. Ultimately, I will probably make bootcharts
not go to disk other than the journal by default.

A single one-liner can be used to get the latest bootchart automatically:

$ journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518
--field=BOOTCHART > bootchart.svg

    bootchart: put the bootchart into the journal.

    This bit of code is mostly stolen from coredump.c. We construct
    a simple journal message and append the bootchart file in the
    journal automatically.

    You can extract the latest bootchart from the current boot with
    something like:

    $ journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518
--field=BOOTCHART

    which prints it to stdout.

    None of the other logic is touched. The journal entry is created
    even if bootchart was run manually, which is probably wrong.
