I would like some help understanding the portions of DSpace that manage
statistics and metrics.  I would appreciate any corrections to my
understandings

The following menu options provide statistics and metrics.

   - Administrative
      - Statistics
   - Statistics
      - Usage
      - Search
      - Workflow
   - Monthly Reports

As I was researching this in this forum, I read that there is a distinction
between "usage statistics" and "content statistics".

If I understood this correctly,

   - usage statistics are generated from solr/statistics
   - these are accessed under "Statistics"
   - content statistics are generated from dspace log files and stored in
   .dat files in /log
      - these are accessed under "Administrative/Statistics"
   - monthly reports are generated from .dat files and saved as stored in
   html files in /reports
      - these are accessed under "Monthly Reports"

In order to generate these properly, the following cron jobs must be run on
a regular basis.

   - usage statistics
      - stats-util -o (hourly)
   - content statistics
      - stat-general (daily)
      - stat-monthly (daily)
   - montly reports
      - stat-report-general (daily)
      - stat-report-monthly (daily)

I am currently encountering 2 issues with my content statistics.

   - I have lost meaningful statistics in production for the last 3 months.

      - I changed my log4j logging level from INFO to WARN.  Could this
      have been the cause?
   - In my development environment, I am capturing a lot of garbage entries
   under "All Actions Performed".
      - The entries appear to be improperly parsed log file entries.

I would appreciate any clarification that the community can provide.

Thanks, Terry
