The Audit Trail feature initiates an audit message when the system detects an audited event such as a user logging in or logging out of the Metasys system, commanding an item, or changing the configuration of a device. An audit message is stored in the Audit Repositories of the device that generated the audit message. When the local audit repository is full, you can send its audit messages to an ADS (ADX) repository defined as the Default Destination for permanent storage.
The Audit Message and Audit Viewer allows you to view audit messages stored in the audit repository of the selected device. You can determine how to sort and filter the audit messages that appear in the Audit Viewer as well as forward them to the defined default destination. You can add annotations to audit messages and view them when displayed on a Metasys Server . You can also define customized annotations and add these custom annotations to audit messages.
For sites with MVE installed, configure the following attributes in the Site Object:
These settings are used by MVE sites to enable the MVE desired annotations and electronic signature for audit messages. You can apply these settings at the site level or down to the object level as needed. You can set the MVE site to require only annotations, only electronic signatures, both annotations and signatures, or neither annotations nor signatures. Non-MVE sites may optionally define and use annotations; however, electronic signatures are specific to MVE sites.
When both annotations and signatures are required, and a user acknowledges or discards an audit message, they are prompted to reauthenticate and enter a reason and annotation for the action. The user’s login name, date and time of signature, and the reason for signature are saved as part of the annotation. You cannot delete annotations on an MVE site.
See Configuring Annotation and Electronic Signature Requirements in the Site Object in MVE in the Site Management Portal User Interface section. For additional information, refer to the Metasys for Validated Environments on Site Management Portal Technical Bulletin (LIT-12011327).
