Build Status Github Releases (by Release)


Mathlion is a Kibana extension that enables equation parsing and advanced math under Timelion. Check out what it can do in the documentation


Copy the last installation url for your version of Kibana from the repository releases. The file follows the naming where the first version is the one of mathlion, the second version indicated it's the one in Kibana.

Remember that starting from Kibana 5.0 you always need an update version of every plugin for it to start as indicated here.

#Kibana >= 5.x

./bin/kibana-plugin install

#Kibana 4
./bin/kibana --install mathlion -u


.es(*).math("a=source")  //the variable "a" now contains the elasticsearch query.
.nop().math("a")  //this row now equals the former elasticsearch query

.es(*).math("source") //return the .es(*) query
.es(*).math("source+5") // add 5 to the .es(*) query

.nop().math("a=a+2 ; a=a+3 ")  //adds 5 to a
.nop().math("a=a+2 ; a=a+3 ; a ")  //adds 5 to a and displays a+5

.es(*).math("a=source")  //this query is invisible and does not generate an axis
.es(*).math("a=source; a")  //this query does

.nop.math("sqrt(3^2 + 4^2)") //returns 5

//Calculate power comsumption based on measured current and stimated voltage (in Europe)

//plot the horizontal statistical mean and variance
.es(*).math("me=mean(source); va=var(source)")
