Alert Detail Table
Use this display to track and manage all alerts that have occurred in the OCM system, add comments or assign Owners to alerts. Alerts are color-coded to visually indicate the alert status:

Red	Critical state: The critical threshold for this alert has been exceeded.
Yellow	Warning state: The warning threshold for this alert has been exceeded.

Alert Name Filter	Select an alert type (also referred to as the alert name) to show in the table, or select * (asterisk) to show all alert types. The table lists all sources (which are stated in the Alert Index column) that exceeded the warning threshold for the selected alert type. Because a single alert type is applied to multiple sources (nodes or caches), if you select the OcAvailableMemoryLowNodeSpike alert type, for example, multiple nodes might be shown (if they exceeded the warning threshold for that alert type). And if you select the OcCapacityLimitCache alert type, multiple caches might be shown (if they exceeded the warning threshold for that alert type). If you select * (asterisk), all alert types are shown for all nodes and caches that exceeded the warning threshold for any alert type. By default, all alert types are shown.
Alert Text Filter	This filter uses Regex filtering. Enter the (case-sensitive) string to search in the Current Alerts table Alert Text column, then press Enter. To remove the filter, delete the text and press Enter. For example, to display only Warning alerts, enter *Warning, then press Enter. The Current Alerts* table then displays only alerts with Warning in the Alert Text string.
Show Critical Alerts Only	Check to show only critical alerts in the table (and no warning alerts). Critical alerts have a severity level of 2. By default, critical and warning alerts are shown.
Show Cleared	Check to show cleared alerts. An alert is considered cleared when the source for the alert (node or cache) returns to below the alert threshold. By default, warning and critical alerts are shown.
Show Acknowledged	Check to show acknowledged alerts. Acknowledged alerts were manually acknowledged. Acknowledged alerts are automatically removed from the Current Alerts table. By default, warning and critical alerts are shown.
Owner Filter	Select the alert Owner to show alerts for in the table.
	All	Shows alerts for all Owners in the table: Not Owned and Owned By Me alerts.
	Not Owned		Shows only alerts without Owners in the table.
	Owned By Me		Shows only alerts for the current user in the table.
Alert Settings Conn OK
	Red			The Alert Server is disconnected.
	Green			The Alert Server is connected.

Total	The total number of alerts currently listed in the table.
Critical	Check to show alerts in the table that are currently in a critical state. Also shows the total number of alerts that are currently in a critical state and currently listed in the table.
Warning	Check to show alerts in the table that are currently in a warning state. Also shows the total number of alerts that are currently in a warning state and currently listed in the table.

Current Alerts	The Current Alerts table lists all alerts for all sources (nodes and caches) that exceeded an alert threshold. Filter the alert types shown using the Show Type drop-down list. Filter the alert states shown by selecting Show Critical Alerts Only, Show Cleared or Show Acknowledged. Sort the data by column using the button. By default, critical and warning alerts are shown.
	Time			The date and time the alert was issued.
	Cleared			When checked, the alert cleared. An alert is cleared when the source for the alert (a node or cache) returns to below the specified alert threshold. To include cleared alerts in the table, select Show Cleared.
	Acknowledged			When checked, the alert was manually acknowledged. Acknowledged alerts are automatically removed from the Current Alerts table. To include cleared alerts in the table, select Show Acknowledged.
	Alert Name			The alert type. Alert types contain alert threshold definitions. A single alert type applies to all nodes or caches in the cluster. For example, the OcAvailableMemoryLowNodeSpike alert type applies to multiple nodes, and the OcCapacityLimitCache alert type applies to multiple caches.
	Alert Index			The Oracle Coherence source from which the alert originated. If the alert is a cluster alert the Alert Index is the the cluster name. Otherwise, the Alert Index is the cluster name followed by the node or cache name.
	Alert Text			Descriptive information about the alert.
	ID			Unique string identifier for the alert.
	Owner			When checked, the alert was closed by a user. To see the Closed table column, select the Closed checkbox (on the lower left).
	Severity			The severity level of the alert. 0: The alert limit has not been exceeded therefore the alert is not activated. 1: The alert warning limit was exceeded. 2: The alert alarm limit was exceeded.
	Source			The name of the Data Server reporting the alert.
