js-analyser-util

##Util package to analyse instrumented and collected data from Node.JS projects using js-analyser

###Usage mvn package to build jar with dependencies

###Save summary from raw instrumented variable values

java -cp target/jsanalyser_util-1.0-SNAPSHOT-jar-with-dependencies.jar variable.summary.VariablesAndValues  <rawInstrumentLogfile> [OPTIONAL-summaryFilePath | DEFAULT- [rawInstrumentLogfile]summary.txt]

###Further analyse variable values using summary file created

java -cp target/jsanalyser_util-1.0-SNAPSHOT-jar-with-dependencies.jar variable.summary.VariableValuesIntoFiles 

Options:
  * -i, --input
       Input path of summary file
  * -o, --output
       Output path of result. Valid folder to save each variable in seperate
       file. Valid text file to save all variables in single file
    -q, --quartile
       Include to save quartiles of each variable in a single file rather than
       every value
       Default: false
    -s, --single
       Include to save all variables in singe file. Default is to save each
       variable in seperate file
       Default: false
    -t, --total
       Threshold to select variables with minimum total values
       Default: 50
    -u, --unique
       Threshold to select variables with minimum unique values
       Default: 1

####Save all values of all variables into one file as variable name -> value pair. (Default task)

Ex: variable1.csv

variable1	value
v1	20
v1	2
v2	232

####Save each variable into seperate file with all values recorded for that variable. (Include -s option to enable this)

Ex: variable1.csv

variable1
20
2
232

####Save each variable into seperate file with all values recorded for that variable. (Include -s option to enable this)

Ex: variable1.csv

norm- Quartiles of normalized values (Values normalzied between 0-1)

Name	min	1st quartile	median	3rd quartile	max	norm 1st quartile	norm median	norm 3rd quartile
var1	-10.12	-7.2	-2	3	11.23	0.25	0.4	0.8
var2	12	71	201	312	1121	0.2	0.6	0.9

###Other util Classes

####github This package contains classes to analyse GitHub usiing its APi. (Include GITHUB_ACCESS_TOKEN in GithubConstants)

• List repositiories based on search query
• List files based on the frequency of changes in given commits
• List commit ids with certain additions/delitions

####cluster.em

• EM CLustering algorithm implementation using Mixture of Gaussians
• Gaussians per cluster is dynamic thus, automatically defined based on the cluster values
