When you have a static website on your company or just for yourself you still need to monitor it to ensure it’s operational. so let’s do this with only 2 metrics.
First metric is HTTPS
by monitoring HTTPS we know that the SSL certificate is ok and the web server is responding, that’s two metrics for the price of one.
Second metric is Web-scraping
when we web scraping our website we know if the content is served as it should be thus making sure our web server responded with content pages and not empty pages.
Worth mentioning third metric
you’ll probably want to add page speed metric to make sure the website is responding fast enough for visitors.
Summary
I like to keep things simple and by using only those 2 metrics I can make sure the website is working as expected and I don’t need to monitor more than 2 or 3 metrics, I just monitor the metrics that important the most.
