This OCTET STRING carries a URL related to an HP OpenView Internet Services trap, letting the recipient drill down for more detail, and is only accessible as part of a notification (accessible-for-notify). Admins can follow this URL directly from a trap-handling console to jump into OVIS for further investigation of the alarm. For example, hpOVISDrillDownUrl might point to an OVIS web console page showing the historical response-time graph for the probe that raised the alert.
