Collector for BW - Java Stack Events

The technical name of the Collector for BW – Java Stack Events is /DVD/MON_BW_CL_COL_JAVAST_EVT.

This collector collects KPIs about Java Stack events. The KPIs are specified via the KPI definition and the input table /DVD/MON_BWJVNDD.

The input table /DVD/MON_BWJVNDD sets the extended KPI definition. It contains the following fields:

System ID

System ID

Object name

OLAP statistics object name (QueryID, TemplateID, etc.)

Do not check

Do not check (exclude) this object

Do not run

Do not run event 12503 on this object

Parameters

The following parameters are used for this collector:

Parameter name

Description

DELAY_TO_CHECK_RSDDSTATS

Delay before checking RSDDSTAT

JAVASTACK_COUNT_12503_X_MINUTES

Java Stack count

JAVASTACK_MIN_12503_VARIANCE

The collector also provides detailed information in the detail tables for relevant KPIs. The first detail table is called BW Java Stack no. of 12503 per node – /DVD/MON_BWJVNOD. It contains the following fields:

Client

Timestamp

System ID

Object name 

Alerts count

Do not check

Do not run event 12503 on this node

Min value of heap %

Max value of heap %

The second detail table is called BW failed query on Java Stack – /DVD/MON_BWMISJV. It contains the following fields:

Timestamp

System ID

BW statistics: Day

BW statistics: Time

SESSIONUID

STEPUID

Internal ID of query runtime object

Internal type of query runtime object

OLAP statistics event

UTC time stamp in long form

Username

OLAP statistics object name (QueryID, TemplateID, etc.)

BW statistics: Number

Validity period

Some KPIs are provided in the standard delivery with the collector as examples:
