A read-only status string reporting the health of the Contivity's OCSP (Online Certificate Status Protocol) responder integration, used as a real-time alternative to CRL checking. An admin relying on OCSP for certificate validation needs to know when the service degrades, since a non-Healthy OCSP path could either block valid connections or, worse, silently fail open. If ocspServer reports "Warning" during a certificate rollout, the admin would check connectivity to the OCSP responder before assuming all client certificate checks are being validated correctly.
