IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

DCS Stack attributes

The DCS Stack attributes reports information about the statistical data within the entire WAS domain, including multiple nodes and servers.

Examples of DCS Stack attributes include; the incoming and outgoing message size, the number of incoming and outgoing messages, congestion events, and message buffer reallocations. The attributes within this group are used to build the DCS Stacks workspace.

For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.

Average Incoming Message Size

The average size (in bytes) of the messages that were received by the DCS stack. Format is positive integer.

Average Outgoing Message Size

The average size (in bytes) of the messages that were sent through the DCS stack. Format is positive integer.

Coalesce Time

The amount of time it actually takes to coalesce a view. Format is decimal (formatted to 3 decimal places).

DCS Stack Name

The name of the Topic Space. The value format is an alphanumeric string, with a maximum of 256 characters.

Group Size

The size of the group the local member belongs to. Format is positive integer.

High Severity

Congestion Events

The number of times that a high severity congestion event for outgoing messages was raised. Format is positive integer.

Incoming Messages

The number of messages received by the DCS stack. Format is decimal (formatted to 3 decimal places).

Instrumentation Level

The instrumentation level for the DCS stack. For WebSphere 6 or higher, the valid values are None, Basic, Extended, All, Custom. Blank if no instrumentation level is set.

Interval (sec)

The length (in seconds) of the sampling interval. Format is positive integer.

Join View Change Time

The time to do a merge view change. The DCS stack is blocked during this time. Format is decimal (formatted to 3 decimal places).

Maximum Incoming Message Size

The maximal size (in bytes) of the messages that were received by the DCS stack. Format is positive integer.

Maximum Outgoing Message Size

The maximal size (in bytes) of the messages that were sent through the DCS stack. Format is positive integer.

Message Buffer Reallocations

The number of message buffer reallocations due to inadequate buffer size. If this number is larger than 20 percent of the number of sent messages, contact IBM Support. Format is positive integer.

Minimum Incoming Message Size

The minimal size (in bytes) of the messages that were received by the DCS stack. Format is positive integer.

Minimum Outgoing Message Size

The minimal size (in bytes) of the messages that were sent through the DCS stack. Format is positive integer.

Node Name

The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.

Origin Node

The name of the server subnode. Alphanumeric string. Maximum 128 characters.

Outgoing Messages

The number of messages sent through the DCS stack. Format is positive integer.

Remove View Change Time

The time to do a split view change. The DCS stack is blocked during this time. Format is decimal (formatted to 3 decimal places).

Row Number

The row number. Format is positive integer.

Sample Date and Time

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.

Server Name

The name of the application server. Alphanumeric string.

Sent Messages

The number of messages sent through the DCS stack. Format is positive integer.

Summary

Whether this row is a summary row of statistical totals for all rows. Valid values are No and yes.

Suspicions

The number of times that the local member suspected other members. Format is positive integer.

Synchronization Completion Time

The amount of time needed to guarantee that all view members are synchronized. Format is decimal (formatted to 3 decimal places).

Synchronization Timeouts

The number of times that the synchronization procedure timed out. Format is positive integer.

View Changes

The number of times that this member underwent view changes. Format is positive integer.
