 The scripts that don't use `grpcurl` to pull data require the `grpcio` Python package at runtime and generating the necessary gRPC protocol code requires the `grpcio-tools` package. Information about how to install both can be found at https://grpc.io/docs/languages/python/quickstart/

+The scripts that use [InfluxDB](https://www.influxdata.com/products/influxdb/) for output require the `influxdb` Python package. Information about how to install that can be found at https://github.com/influxdata/influxdb-python. Note that this is the (slightly) older version of the InfluxDB client Python module, not the InfluxDB 2.0 client. It can still be made to work with an InfluxDB 2.0 server, but doing so requires using `influx v1` [CLI commands](https://docs.influxdata.com/influxdb/v2.0/reference/cli/influx/v1/) on the server to map the 1.x username, password, and database names to their 2.0 equivalents.

 ## Usage
 
 For `parseJsonHistory.py`, the easiest way to use it is to pipe the `grpcurl` command directly into it. For example:
