creating/editing a notification rule NUMBER(2) The statement above will be true when the attributes of the alert match the following condition: When a severity occurs for the target, the notification system creates an instance of the MGMT_NOTIFY_SEVERITY object and populates it with values from the severity The severity codes in Table 4-6 have been defined as constants in the MGMT_GLOBAL package and can be used to determine the type of severity in the severity_code field of the MGMT_NOTIFY_SEVERITY object METRIC_NAME MS Agent time skew (mins)Consecutive metadata upload failure count Name of

corrective action status change attributes (such as new status, job name, job type, notification rule, or rule owner) to PL/SQL procedures or OS commands/scripts allows you to customize automated responses to status changes For example, you many want to call an OS script to open a trouble ticket for an in-house support trouble ticket system if a critical corrective action fails to run In this case, you will want to pass status (for example, Problems or Aborted) to the script to open a trouble ticket and escalate the problem The Short Format (Example 4-4) sends a concise, text e-mail that is limited to a configurable number of characters, thereby allowing the e-mail be received as an SMS message or page The content of the message can be sent entirely in the subject, entirely in the body or split across the subject and body For example, in the last case, the subject could contain the severity type (for example, Critical) and the target name The body could contain the time the severity occurred and the severity message Since the message length is limited, some of this information may be truncated If truncation has occurred there will be an ellipsis end of the message

severity types that relate to a target's availability are: Note: Use / to escape and [ or ] if you want to add attribute names, operators, or IF clauses to the actual e-mail Table 4-8 lists all

notifications globally at the notification method level may not be provide sufficient flexibility For example, you may want to have different repeat notification settings based on the metric type

those defined at the notification method level Comments may also be placed at the end of a line of text RAW(16) For metrics that monitor a set of objects, the KEY_VALUE indicates the specific object
