IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
High Availability Manager attributes
The High Availability Manager attributes provide aggregated information about the high availability managers.
The attributes within this group are used to build the High Availability Manager workspace.
- The attributes within this attribute group contain zeros for performance data if your site set configuration value Resource Data Collection Method to On Demand (for on-demand sampling) and you have not yet run applications that generate performance data. To report performance data in these attributes after installing and configuring the data collector, use the WebSphere administrative console to set the appropriate PMI instrumentation level.
- The Tivoli Enterprise Monitoring Agent is set by default to provide on-demand sampling; thus the attributes within this attribute group initially contain zeros until you select the workspace and then select it again later. Each time you select the workspace, these attributes are updated with the latest data.
For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.
The time taken (in milliseconds) to rebuild the global state of the bulletin-board. During this time no messages will be received by the subscribers. If this time is too high, and is unacceptable, you may want to increase the number of coordinators. Format is decimal (formatted to 3 decimal places).
The total number of subjects managed. Format is positive integer. This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.
The total number of bulletin-board subscriptions. Format is positive integer. This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.
The time taken (in milliseconds) to rebuild the global group state. During the rebuild time, no fail-over can happen. If this time is too high and is unacceptable for the desired availability, you may want to increase the number of coordinators. For proper operation of this counter, host the active coordinator in an application server other than the deployment manager. Format is decimal (formatted to 3 decimal places).
The instrumentation level for availability manager counters. For WebSphere 5, the valid values are None, Low, Medium, High, and Maximum; for WebSphere 6 or higher, the valid values are None, Basic, Extended, All, Custom. Blank if no instrumentation level is set.
The length (in seconds) of the sampling interval. Format is positive integer.
The total number of subjects being posted to locally. The number includes the proxy postings (if any) done by the core group bridge service on behalf of servers belonging to different WebSphere cells. Format is positive integer. This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.
Local Bulletin-Board Subscriptions
Indicates the total number of bulletin-board subscriptions being posted to locally.
The total number of local groups. Format is positive integer. This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.
The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.
The name of the server subnode. Alphanumeric string.
The row number. Format is positive integer.
The date and time the Tivoli Enterprise Management Agent collected the data. The valid format is a 12-character timestamp. For the STR and SCAN functions, the format is MM/DD/YY HH:MM:SS; the following table shows the values contained in this character string:
Format of the 12-character timestamp
Character String Meaning MM Month DD Day YY Year HH Hour MM Minute SS Second
Example: 09/13/06 18:32:03 indicates the data was collected on September 13, 2006, at 18:32:03.
This attribute was designed for logging and reporting data-collection times rather than for creating situations. To specify a time and date for comparison and testing, use attributes from the Universal Time or Local Time groups.
The name of the application server. Alphanumeric string.
Whether this row is a summary row of statistical totals for all rows. Valid values are No and Yes.
