Managing Traffic Ops Extensions
*******************************

Each script is a separate bash script located in ``$TO_HOME/bin/checks/``. 

The extensions must be registered with Traffic Ops in order to display a column on the Server Check page. The list of currently registered extensions can be listed by running ``/opt/traffic_ops/app/bin/extensions -a``.

The below extensions are automatically registered with the Traffic Ops database (``to_extension`` table) at install time (see ``traffic_ops/app/db/seeds.sql``). However, cron must still be configured to run these checks periodically. 

The scripts are called as follows: ::

  
  $TO_HOME/bin/checks/To<name>Check.pl  -c "{\"base_url\": \",https://\"<traffic_ops_ip>\", \"check_name\": \"<check_name>\"}" -l <log level>
  where:

  <name> is the type of check script
  <traffic_ops_ip> is the IP address of the Traffic Ops Server
  <check_name> is the name of the check. For example: CDU, CHR, DSCP, MTU, etc...
  <log_level> is between 1 and 4, with 4 being the most verbose. This field is optional


Example Cron File
=================
Edit with ``crontab -e``. You may need to adjust the path to your $TO_HOME to match your system.
