2. JON Deployment
Production Server (1) Production Server (x)
JON JON
JBoss JBoss
Agent Agent
All the Remote
JON Remote
other JON Client
Database Java API
RHQ bits App
JON Server Client

3. The Goal - View Behaviour of Multiple
Machines

4. Approach (1/2) – Client App
machine datetime low av max
servername1:1099 2011-09-01T00:00:00.000+01:00 31.0 31.0 31.0

5. Approach (2/2) - R
http://www.r-project.org/
#Read dataset
ajpConnActiveThreads <- read.table(dataSetFile, header=TRUE, sep="")
ajpConnActiveThreads$datetime <- as.POSIXct(ajpConnActiveThreads$datetime, tz="", '%Y-%m-%dT%H:%M:%OS')
#Calculate “Trimmed” Mean
allMachineTrimmedMean <- apply(justNumbers, 1, mean, trim=0.1)
#Draw Graph
jpeg(outputGraphFileName)
plot(threadActiveXRange, threadActiveYRange, type="n", …, col.lab="darkblue")
axis.POSIXct(1, at=seq(r[1], r[2], by="hour"), format="%H:%M", las=2)
axis(2, at=yAxisAt, las=2)
lines(finalData$datetime, finalData[[dataIndex]], col="red")
lines(finalData$datetime, allMachineTrimmedMean, col="blue")
dev.off()
