plotResponseTimeScatter: Generates a scatter plot of response times

Description

Scatter plot (base graphics object) of response times from a data. The log form uses a log10 y axis.

Usage

plotLogResponseTimeScatter(times, elapsed,timeDivisor = 1000, ylabText = "Time (log sec)") 
plotResponseTimeScatter(times, elapsed,timeDivisor = 1000, ylabText = "Time (sec)")

Value

Generates a base graphics plot. This function is intended to be wrapped in a call to plotSave

Arguments

times: POSIXct timestamps
elapsed: elapsed milliseconds
timeDivisor: divisor to adjust times to seconds (the default value of 1000) or some other interval
ylabText: divisor to adjust times to seconds (the default value of 1000) or some other interval

Examples

Run this code

# \dontshow{
datd = paste0(tempdir(),"/minconfigtemp")
unlink(datd)
dir.create(paste0(tempdir(),"/minconfigtemp"))
logfile = paste0(datd,"/log.log")
fileConn = gzfile(system.file("extdata", "compressed.log", package = "WebAnalytics"))
writeLines(readLines(fileConn,n=100),con=logfile)
close(fileConn)
# set the files directory name suitable for an R example
configVariableSet("config.workdir", tempdir())
setDTthreads(threads = 1)
# }
logFileName = logFileNamesGetLast(dataDirectory=datd, 
  directoryNames=c(".", "."), 
  fileNamePattern="*[.]log")[[1]] # only want one

cols = logFileFieldsGetIIS(logFileName)

logdf = logFileRead(logFileName, columnList=cols, 
            logTimeZone = "", timeFormat = "")

plotResponseTimeScatter(logdf$ts, logdf$elapsed) 
plotLogResponseTimeScatter(logdf$ts, logdf$elapsed)
