  ### Finding log files in the filesystem

  Log files are located in the `https://FUSION_HOST:FUSION_PORT/var/log` directory. Generally, the log files below are the most useful in diagnosing an issue:

  * API logs

    `https://FUSION_HOST:FUSION_PORT/var/log/api/api.log` and `https://FUSION_HOST:FUSION_PORT/var/log/api/gc_<timestamp>.log.0.current`
  * Connectors logs

    `https://FUSION_HOST:FUSION_PORT/var/log/connectors-classic/connectors-classic.log` and `https://FUSION_HOST:FUSION_PORT/var/log/connectors-rpc/connectors-rpc.log`

  If it is apparent that additional components are involved, collect their logs and associated `gc` logs from the `https://FUSION_HOST:FUSION_PORT/var/log` directory.
