• Click the "Save" button to add the monitor.

Uptime Kuma will now monitor the SSL/TLS handshake and certificate expiration status in addition to the availability and response time.

Monitoring Specific Application Endpoints

In some cases, you may want to monitor specific endpoints or APIs of your application. Uptime Kuma allows you to create custom monitors for this purpose. Here's how:

• Access the Uptime Kuma web interface.

• Navigate to the "Monitors" tab and click the "Add Monitor" button.

• Provide a name for the monitor and enter the URL of the specific endpoint you want to monitor.

• Select the monitor type based on the protocol or technology your application uses (e.g., HTTP, HTTPS, TCP, etc.).

• Configure any additional settings specific to your application's endpoint.

• Save the monitor to start monitoring the specified endpoint.

Uptime Kuma will now track the availability and response time of the targeted application endpoint.

Advanced Monitoring Options

Uptime Kuma offers advanced monitoring options to cater to various scenarios and requirements. Some of the advanced options include:

• Specifying custom request headers for HTTP and HTTPS monitors.

• Setting up HTTP authentication for password-protected websites or applications.

• Configuring custom check intervals and timeouts.
