Server Monitoring is a package that will periodically monitor the health of your server and website. It provides healthy/alarm status notifications for Disk Usage, an HTTP Ping function to monitor the health of external services, and a validation/expiration monitor for SSL Certificates.
This package works by setting up a config file and then having a
monitor:run artisan command set on a schedule. When it runs it will alert you via email, Pushover, Slack, or logged to the filesystem.
It currently supports the following monitors:
Disk Usage Monitors
Disk usage monitors check the percentage of the storage space that is used on the given partition, and alert if the percentage exceeds the configurable alarm percentage.
HTTP Ping Monitors
HTTP Ping monitors perform a simple page request and alert if the HTTP status code is not 200. They can optionally check that a certain phrase is included in the source of the page.
SSL Certificate Monitors
SSL Certificate monitors pull the SSL certificate for the configured URL and make sure it is valid for that URL. Wildcard and multi-domain certificates are supported.
The monitor will alert if the certificate is invalid or expired, and will also alert when the expiration date is approaching. The days on which to alert prior to expiration is also configurable.
