Structure of the Metric Reference Manual

This manual contains chapters for the Microsoft SQL Server, IBM DB2 Database and Sybase Adaptive Server Enterprise Database. The metrics in these chapters appear in alphabetical order according to category.

Metric Information

The information for each metric comprises a description and user action if available:

  • Description

    Provides an explanation following the metric name. This text defines the metric and, when available, provides additional information pertinent to the metric.

  • User Action

    Suggests how to solve the problem causing the alert.

Definitions of Columns in Metric Summary Tables

The Metric Summary table in Enterprise Manager Cloud Control is part of the overall metric information. The following table provides descriptions of columns in the Enterprise Manager Metric Summary table.

Column Header Column Definition

Target Version

Version of the target, for example, 9.0.2.x and 10.1.0.x. The x at the end of a version (for example, 9.0.2.x) represents the subsequent patchsets associated with that release.

Collection Schedule

The rate at which the Management Agent collects data. The collection frequency for a metric comes from the Enterprise Manager default collection file for that target type.

Default Warning Threshold

Value that indicates whether a warning alert should be initiated. If the evaluation of the warning threshold value returns a result of TRUE for the specified number of consecutive occurrences defined for the metric, an alert triggers at the warning severity level.

Default Critical Threshold

Value that indicates whether a critical alert should be initiated. If the evaluation of the critical threshold value returns a result of TRUE for the specified number of consecutive occurrences defined for the metric, an alert triggers at the critical severity level.

Alert Text

Message indicating why the alert was generated. Words that display between percent signs (%) denote variables. For example, Disk Utilization for %keyValue% is %value%% could translate to Disk Utilization for d0 is 80%.
