With ever more services depending on Shibboleth it's important to make sure everything is working properly and end users can successfully access the resources they need.

What to check for

IdP Monitoring

Retrieving Status Information about the IdP
Terracotta cluster health checking

SP Monitoring

Retrieving Status Information about the SP
The SP Status handler will need to be configured to be accessible by your monitoring tools via the acl attribute.
Checking the Session handler is not enough as this does not detect e.g. whether shibd is running.

DS Monitoring

TBD

Contributions

Tools, frameworks, scripts, etc. to check availability of your services.
Feel free to document your solution here (or link to existing documentation).
