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.

PHP Fatal Error: Uncaught Error: Call to undefined function – OJS

bindtextdomain

  • Error 500 while setting distribution
  • The 500 error in registration page
  • PHP Fatal error: Uncaught Error: Call to undefined function bindtextdomain() in /lib/pkp/lib/vendor/sokil/php-isocodes/src/AbstractDatabase.php:87
  • Failed AJAX request or invalid JSON returned

If you get a message like this:

PHP Fatal Error: Uncaught Error: Call to undefined function bindtextdomain() in ...

…then your PHP installation is missing support for the gettext extension. You need to install or enable it.

Failed Ajax request or invalid JSON returned

  • Failed Ajax request or invalid JSON returned

Cause

This warning is cosmetic, but because it’s being sent out to the browser, it’s interfering with the JSON response.

Solution

Configure your PHP so that errors/warnings are sent to the log, not the browser.

PHP setting

display_errors = Off

Check PHP Extension

gettext extension

Check file permission and ownership
