    The total number of milliseconds (ms) that the mongod processes have spent writing (i.e. flushing) data to disk. Because this is an absolute value, consider the value of `flushes` and `average_ms` to provide better context for this datum.
    type: long
  </definition>
  <definition term="mongodb.status.background_flushing.average.ms">
    The average time spent flushing to disk per flush event.
    type: long
  </definition>
  <definition term="mongodb.status.background_flushing.last.ms">
    The amount of time, in milliseconds, that the last flush operation took to complete.
    type: long
  </definition>
  <definition term="mongodb.status.background_flushing.last_finished">
    A timestamp of the last completed flush operation.
    type: date
  </definition>
</definitions>


## journaling

Data about the journaling-related operations and performance. Journaling information only appears for mongod instances that use the MMAPv1 storage engine and have journaling enabled.
<definitions>
  <definition term="mongodb.status.journaling.commits">
    The number of transactions written to the journal during the last journal group commit interval.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.journaled.mb">
    The amount of data in megabytes (MB) written to journal during the last journal group commit interval.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.write_to_data_files.mb">
    The amount of data in megabytes (MB) written from journal to the data files during the last journal group commit interval.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.compression">
    The compression ratio of the data written to the journal.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.commits_in_write_lock">
    Count of the commits that occurred while a write lock was held. Commits in a write lock indicate a MongoDB node under a heavy write load and call for further diagnosis.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.early_commits">
    The number of times MongoDB requested a commit before the scheduled journal group commit interval.
    type: long
  </definition>
</definitions>


## times

Information about the performance of the mongod instance during the various phases of journaling in the last journal group commit interval.
<definitions>
  <definition term="mongodb.status.journaling.times.dt.ms">
    The amount of time over which MongoDB collected the times data. Use this field to provide context to the other times field values.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.prep_log_buffer.ms">
    The amount of time spent preparing to write to the journal. Smaller values indicate better journal performance.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.write_to_journal.ms">
    The amount of time spent actually writing to the journal. File system speeds and device interfaces can affect performance.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.write_to_data_files.ms">
    The amount of time spent writing to data files after journaling. File system speeds and device interfaces can affect performance.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.remap_private_view.ms">
    The amount of time spent remapping copy-on-write memory mapped views. Smaller values indicate better journal performance.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.commits.ms">
    The amount of time spent for commits.
    type: long
  </definition>
  <definition term="mongodb.status.journaling.times.commits_in_write_lock.ms">
    The amount of time spent for commits that occurred while a write lock was held.
    type: long
  </definition>
