Mnfst Puppet Helper Scripts

Scripts which use the Puppet dashboard data and update the mnfst-neo graph information.

Prereqisites are curl, awk, jq and csvtool to be available in the system.

Usage:

  • Make sure to set the DASHBOARD_HOST and MNFST_HOST environment variables
  • Trigger ./run.sh NO once every 10-30 minutes (depending on the assumed change rate)
  • Trigger ./run.sh YES once or twice a day to import new server / file information for each system and remove relations which are not relevant anymore.
