SD_JOURNAL_GET_USAGE(3) sd_journal_get_usage SD_JOURNAL_GET_USAGE(3)
sd_journal_get_usage - Journal disk usage
#include <systemd/sd-journal.h>
int sd_journal_get_usage(sd_journal *j, uint64_t *bytes);
sd_journal_get_usage() determines the total disk space currently
used by journal files (in bytes). If SD_JOURNAL_LOCAL_ONLY was
passed when opening the journal, this value will only reflect the
size of journal files of the local host, otherwise of all hosts.
sd_journal_get_usage() returns 0 on success or a negative
errno-style error code.
All functions listed here are thread-agnostic and only a single
specific thread may operate on a given object during its entire
lifetime. It's safe to allocate multiple independent objects and
use each from a specific thread in parallel. However, it's not
safe to allocate such an object in one thread, and operate or
free it from any other, even if locking is used to ensure these
threads don't operate on it at the very same time.
Functions described here are available as a shared library, which
can be compiled against and linked to with the
libsystemd pkg-config(1) file.
sd_journal_get_usage() was added in version 190.
