Time for action – setup of a cron-based report generation

1. Logon to your Cacti server.

2. Create a new file in /etc/cron.d for running the report generation:

   vi /etc/cron.d/reportScheduler
   

3. Add the following one line to this file:

   */1 * * * * cactiuser /usr/bin/php /var/www/html/cacti/plugins/nmidCreatePDF/cron_pdf_scheduler.php > /dev/null 2>&1
   

4. Save the file by hitting ESC and entering x.

5. Now logon to your Cacti web interface.

6. Go to Configuration | Settings.

7. Click on the NMID tab.

8. Select Cron as the Scheduler being used.

9. Click on the Save button.

What just happened?

You just changed your scheduler from the poller-based version to a cron-based one. This will allow the Cacti poller to concentrate on polling performance data while the operating system deals with the report generation.
