NAME¶

sd_journal_get_usage - Journal disk usage

SYNOPSIS¶

#include <systemd/sd-journal.h>

int sd_journal_get_usage(sd_journal *j, uint64_t *bytes);

DESCRIPTION¶

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.

RETURN VALUE¶

sd_journal_get_usage() returns 0 on success or a negative errno-style error code.

NOTES¶

All functions listed here are thread-agnostic and only a single thread may operate on a given sd_journal object.

These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
