This Bash script exposes a few functions to create a Grafana data source, and setup the InfluxDB database behind that. It has some configuration functions in the top. It is a continuation of the Python script offered in this Grafana issue comment.

| Description | |
| ----------- | |
| Deadlock is caused by `ibis::fileManager::getFile` (#7 below) locking the fileManager's mutex, and then the constructor | |
| at `ibis::fileManager::storage::storage` (#4 below) locking it in the same thread, when it realizes it needs to make | |
| some room in the cache first. There seem to be many similar code paths where this sort of deadlock will arise, all when | |
| the cache size is near or over `maxBytes`. |
