Installation gotchas: the port and hostname in Cacti settings

A couple of things that tripped me up when installing the Cacti integration were:

• setting the scripts port to 80 instead of 443 in the Cacti web interface. Many (most?) site administrators won't have SSL enabled on their site. This is configured, in Cacti, through:
  1. click "Data Input Methods" on the left sidebar
  2. click "Drupal - User Count" in the data input method list
  3. change 443 to 80 in the "Input String" textarea
  4. save the settings
• before setting up a graph in Cacti, in order for the hostname (i.e. the domain of the site) to get passed to the script, I had to enable it in the data template:
  1. click "Data Templates" in the left sidebar
  2. click "Drupal - User Count" in the data templates list
  3. under "Custom Data" at the bottom, check "Use Per-Data Source Value"
  4. save the settings

  After that, you can set the hostname to get passed after you select "Drupal - User Count" (as is the current example) when creating a new graph as the custom data options.
