Class XSystemReportOperationInfo

java.lang.Object
waggle.core.info.XDTO
waggle.common.modules.systemreport.infos.XSystemReportOperationInfo

public class XSystemReportOperationInfo

extends XDTO

XSystemReportOperationInfo contains data for timed operations, such as API methods and HTTP methods.

Field Summary

String	ID The ID of the operation, which is the JMX Object Name.
String	Legend Optional label that is more user human readable than the ID.
double	RangeCommitTime An approximation of the commit time accumulated in invocations of the operation over the report range.
double	RangeCommitTimePerSecond The CommitTime rate.
double	RangeInvocations A rough approximation of the number of invocations over the report range.
double	RangeInvocationsPercentage This operation's percentage of the total number of invocations across all operations in the range, expressed as a number between 0 and 1.
double	RangeInvocationsPerSecond The Invocations rate.
double	RangeTotalTime An approximation of the total time spent in invocations of the operation over the report range.
double	RangeTotalTimePercentage This operation's percentage of the total time across all operations in the range, expressed as a number between 0 and 1.
double	RangeTotalTimePerInvocation The average number of milliseconds per invocation.
double	RangeTotalTimePerSecond The TotalTime rate.
long	SnapshotCommitTime The value of the JMX CommitTime attribute at the time of report generation.
long	SnapshotInvocations The value of the JMX Count attribute at the time of report generation.
long	SnapshotTotalTime The value of the JMX TotalTime attribute at the time of report generation.

Field Detail

ID

public String ID

The ID of the operation, which is the JMX Object Name.

Legend

public String Legend

Optional label that is more user human readable than the ID.

SnapshotInvocations

public long SnapshotInvocations

The value of the JMX Count attribute at the time of report generation. This value is reset whenever the server restarts.

SnapshotTotalTime

public long SnapshotTotalTime

The value of the JMX TotalTime attribute at the time of report generation. This value is reset whenever the server restarts.

SnapshotCommitTime

public long SnapshotCommitTime

The value of the JMX CommitTime attribute at the time of report generation. This value is reset whenever the server restarts.

RangeInvocationsPerSecond

public double RangeInvocationsPerSecond

The Invocations rate. This is the average number of invocations per second over the system report range. This is an RRD data source.

RangeTotalTimePerSecond

public double RangeTotalTimePerSecond

The TotalTime rate. This is the average amount of total time (in milliseconds) per second that was spent in invocations of the operation. This is an RRD data source.

Note that this value can go above 1000 millis-per-second because the server may process multiple concurrent invocations of a operation. If two clients invoke the same operation at the same time, and each invocation takes 800 milliseconds to complete, then the TotalTimePerSecond for that second is 1600 milliseconds.

RangeCommitTimePerSecond

public double RangeCommitTimePerSecond

The CommitTime rate. This is the average amount of time (in milliseconds) per second that was spent committing the operation. This is an RRD data source.

RangeTotalTimePerInvocation

public double RangeTotalTimePerInvocation

The average number of milliseconds per invocation. This is computed by dividing the RangeTotalTimePerSecond by the RangeInvocationsPerSecond.

RangeInvocations

public double RangeInvocations

A rough approximation of the number of invocations over the report range. This is computed by multiplying the RangeInvocationsPerSecond by the number of seconds in the range.

Note that this approximation could be very inaccurate for smaller sample sizes (small numbers of invocations or short ranges).

RangeTotalTime

public double RangeTotalTime

An approximation of the total time spent in invocations of the operation over the report range. This is a computed value generated by multiplying the RangeTotalTimePerSecond by the number of seconds in the range.

Note that this approximation could be very inaccurate for smaller sample sizes (small numbers of invocations or short ranges).

RangeCommitTime

public double RangeCommitTime

An approximation of the commit time accumulated in invocations of the operation over the report range. This is a computed value generated by multiplying the RangeCommitTimePerSecond by the number of seconds in the range.

Note that this approximation could be very inaccurate for smaller sample sizes (small numbers of invocations or short ranges).

RangeInvocationsPercentage

public double RangeInvocationsPercentage

This operation's percentage of the total number of invocations across all operations in the range, expressed as a number between 0 and 1. This is a computed value generated by dividing this operation's RangeInvocations by the sum of all operations' RangeInvocations.

RangeTotalTimePercentage

public double RangeTotalTimePercentage

This operation's percentage of the total time across all operations in the range, expressed as a number between 0 and 1. This is a computed value generated by dividing this operation's RangeTotalTime by the sum of all operations' RangeTotalTime.
