This is a simple Python program to poll the local CPU utilization every second and push a "% busy" metric to a Zed lake presumed to be running on the local system.
To install and run with needed dependencies in a virtual environment:
git clone https://github.com/philrz/zed-cpu-logger
cd zed-cpu-logger
python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt
./zed-cpu-logger.py
Assuming a Zed lake is listening on the local host, when running you'll see a dot printed as each batch of CPU points is loaded to the pool.
$ ./zed-cpu-logger.py
Loading data to newly-created pool "default"...................
I created this as a continuous source of time-series data to be used with the prototype Grafana Zed data source plugin I also recently developed.
If I were a better Go developer, surely a better approach would have been to develop something like a general purpose Zed lake Telegraf output plugin. That would allow for gathering and ingest of any metric that Telegraf can poll, with CPU being but one example. Perhaps someone with more skills and experience could be inspired to take that on.
