plotParallelismRateImpactOnResponse: Plot response time against degree of parallelism

In WebAnalytics: Web Server Log Analysis

Plot response time against degree of parallelism

Description

Generates a plot of the effect of overall parallelism on response time possibly limited to a single URL in the overall background, the URL whose time is calculated, and by http response type and status.

Usage

plotParallelismRateImpactOnResponse(b, 
      intervalLength = 600, 
			excludeURLOverall="", 
			includeURLOverall="",
			excludeResponse="",
			includeResponse="", 
			excludeStatus="",
			includeStatus="",
			percentileCutoff = 1,
			title="Degree of Parallelism and Response Time", 
			subtitle="")

Arguments

b	a transaction data frame
intervalLength	length of the intervals (in seconds) that parallelism is calculated over
excludeURLOverall	a URL to be deleted from the dataset
includeURLOverall	the URL to be included from the dataset
excludeResponse	a URL to be excluded from the response time calculation
includeResponse	the URL to be used for the response time calculation
excludeStatus	a status to be excluded from the response time calculation, for example success statuses could be excluded. Possible status values are: 'Success', 'Redirect', 'Client Error' or 'Server Error'
includeStatus	a status to filter URLs by, for example, only include success responses in the response time calculation
percentileCutoff	exclude values above the specified quantile, intended for use in excluding outlier events that would distort the elapsed time calculation
title	the plot title
subtitle	the plot subtitle

Value

Returns an R base graphics plot. This function is intended to be wrapped in a call to plotSave

Examples

logFileName = logFileNamesGetLast(dataDirectory=datd, 
  directoryNames=c(".", "."), 
  fileNamePattern="*[.]log")[[1]]

cols = logFileFieldsGetIIS(logFileName)

logdf = logFileRead(logFileName, columnList=cols, 
            logTimeZone = "", timeFormat = "")
plotParallelismRateImpactOnResponse(logdf,
            includeStatus="Success",
            excludeResponse="Static Content Requests",
            percentileCutoff=0.95)
