Crash plugin ============ The crash plugin collects information about daemon crashdumps and stores it in the Ceph cluster for later analysis. Daemon crashdumps are dumped in /var/lib/ceph/crash by default; this can be configured with the option 'crash dir'. Crash directories are named by time and date and a randomly-generated UUID, and contain a metadata file 'meta' and a recent log file, with a "crash_id" that is the same. This plugin allows the metadata about those dumps to be persisted in the monitors' storage. Enabling -------- The *crash* module is enabled with:: ceph mgr module enable crash Commands -------- :: ceph crash post -i Save a crash dump. The metadata file is a JSON blob stored in the crash dir as ``meta``. As usual, the ceph command can be invoked with ``-i -``, and will read from stdin. :: ceph rm Remove a specific crash dump. :: ceph crash ls List the timestamp/uuid crashids for all saved crash info. :: ceph crash stat Show a summary of saved crash info grouped by age. :: ceph crash info Show all details of a saved crash. :: ceph crash prune Remove saved crashes older than 'keep' days. must be an integer.
