#!/bin/sh -e

# Description
# This cron script will automatically run Piwik archiving every hour.
# The script will also run scheduled tasks configured within piwik using
# the event hook 'TaskScheduler.getScheduledTasks'

# It automatically fetches the Super User token_auth
# and triggers the archiving for all websites for all periods.
# This ensures that all reports are pre-computed and Piwik renders very fast.

# Documentation
# Please check the documentation on http://piwik.org/docs/setup-auto-archiving/

# How to setup the crontab job?
# Add the following lines in your crontab file, eg. /etc/cron.d/piwik-archive
#---------------START CRON TAB--
#MAILTO="youremail@example.com"
#5 * * * * www-data /path/to/piwik/misc/cron/archive.sh > /dev/null
#-----------------END CRON TAB--
# When an error occurs (eg. php memory error, timeout) the error messages
# will be sent to youremail@example.com.
#
# Optimization for high traffic websites
# You may want to override the following settings in config/config.ini.php:
# See documentation of the fields in your piwik/config/config.ini.php
#
# [General]
# time_before_archive_considered_outdated = 3600
# enable_browser_archiving_triggering = false
