Janssen Server Installation FAQs#

After installation, how do I verify that the Janssen Server is up and running?#

Health and status of Janssen Server and its various processes can be verified in multiple ways:

Use the Janssen Server Health Check endpoint#

Janssen Server provides a health check endpoint for Authentication module. It can be invoked from commandline using CURL as below:

curl -k https://janssen-host-name/jans-auth/sys/health-check

For a healthy server, this option will return output as below:

Please wait while retrieving data ...

"status": "running",
"db_status": "online"

Access .well-known endpoints#

Janssen Server exposes .well-known endpoint for openid configuration as per the OpenIDConnect RFC. Successful response from this endpoint is also an indicator of healthy authentication module.

From command-line interface, use CURL to access this endpoint. For example:

curl https://janssen-host-name/jans-auth/.well-known/openid-configuration

This should return JSON response from Janssen Server as per OpenId specification. Sample below:
