systemd Developer Lennart Poettering lennart@poettering.net coredump.conf 5 coredump.conf Coredump storage configuration file /etc/systemd/coredump.conf This file configures the behaviour of systemd-coredump, a handler for core dumps invoked by the kernel. All options are configured in the [Coredump] section: Storage= Controls where to store cores. One of none, external, journal, and both. When none the coredumps will be logged but not stored permanently. When external (the default), cores will be stored in /var/lib/systemd/coredump. When journal, cores will be stored in the journal and rotated following normal journal rotation patterns. When both, cores will be stored in both locations. When cores are stored in the journal, they might be compressed following journal compression settings, see journald.conf5. When cores are stored externally, they will be compressed by default, see below. Compression= Controls the type of compression for external storage. One of xz or none. CompressionLevel= Controls the level of compression for external storage. An integer between 0 and 9. See xz1 for more details. ProcessSizeMax= The maximum size in bytes of a core which will be processed. Coredumps exceeding this size will be logged, but the backtrace will not be generated and the core will not be stored. ExternalSizeMax= JournalSizeMax= The maximum (uncompressed) size in bytes of a core to be saved. systemd-journald.service8, coredumpctl1
