This script is specific to a need I had (to monitor website performance continuously every 1-ish second). I put it up here in case others might find it useful. I deploy it on Jelastic hosts around the internet, then use Grafana to view the performance data on a chart. Then I can compare the results to other metrics in grafana (SAN disk availability for example) to look for trends.

cxwWebAgent

Monitors response times of websites and logs the data into a PostgreSQL database. Waits 1 second inbetween requests, not including the time the request actually took. So the requests will never "pile up". A request is run, and once it finishes the program waits 1 second before sending the next request to that same site. All sites listed in the configuration file are run concurrently.

Usage

After downloading:

1. Change directory into cxwWebAgent
2. Run npm install
3. Edit the config/default.json5 configuration file
   • Define some sites to monitor
   • Define a postgreSQL/TimescaleDB database to log the data to
   • Probably want to set debuglogging: true
   • Set thissitename to a string that indicates your monitoring location. You can try 'auto'.
4. Run the script npm start

You should see logging output indicating data is being sent to your database.
