Usage stats shows 0 in the downloaded files

    • Download statistics stop working
    • Usage stats shows 0 in the downloaded files
    • Download data is not yet available
    • How to get the Usage Statistics plugin to work
    • OJS statistics views are 0
    • usageEventLogs files are not moved to stage folder

Checklists

  • Visit Statistics > Articles in the backend, do you see any statistics?
  • Check PHP error log for details on those 500 errors
  • Check that base_url in config.inc.php is set correctly
  • Check log files in the usageStats/usageEventLogs directory (inside your OJS files_dir)
  • Check whether dB metrics is updating.
    • In the SQL database, see if there are row(s) for in the metrics table for the journal. If the journal id is 1, use the following SQL: 
      select count(*) from metrics where context_id=1

      If there are no metrics, your instance may not be set up to process the usage stats logs.

  • Check to see if there is a scheduled task registered for the metrics. 
    select * from scheduled_tasks;

    You should see a listing for plugins.generic.usageStats.UsageStatsLoader. If you do have that listing, your instance may not be running its scheduled tasks and may not have the correct plugins installed.

  • If UsageStatsLoader is running check whether log files being written and the plugin can find the log files for processing.
    • Look in files_dir (defined in config.inc.php) and look for the usageStats directory. In particular, look for log files in: usageStats > usageEventLogs
    • When the usage stats are processed, they are taken out of this directory for processing. You should only see logs since the last run.
    • Check usageStats > archive directory.
  • If everything looks okey
    • Lets check the journal ID 
      select journal_id from journals where path="JOURNALPATH";
    • If it is 1. Then check a usage event log: 
      select * from metrics where context_id=1 and load_id="usage_events_20221113.log" limit 10;

      If there are no entries for that, open up usageStats/archive/usage_events_20201113.log and see if there are any entries for the JOURNALPATH journal.

A quick test. Copy an old usageStats/archive log file into usagestats/stage and run:

php tools/runScheduledTasks.php plugins/generic/usageStats/scheduledTasks.xml

Check the metrics table in the database. A new record should be added to the metrics table.
