computed-columns's Introduction

Computed Columns

An awesome Kibana plugin.

This visualization plugin is like a table, but with computed columns. Every new columns is a computation from normal basics columns. Every new column has it own expression (e.g. col[0] * col[1] / 100).

Considerations

Any mathematical expression can be used to create computed columns. Even parentheses can be used to group expressions - e.g. (col[0] - col[1]) / col[0].
To refence a colums use word col followed by brackets with zero base index inside - e.g. col[1] = column 1 (second column).
Computed column can be used to create new computed columns.
Multiples computed colums will be computed in order, thous, you can only use column index n-1.
Current Release Version: 0.4.1.
Hidden columns are evaluated after computed columns.

Install

From 0.5.x every release includes plugins version (x.y.z) and Kibana version (a.b.c).

From Kibana Installation Path:

./bin/kibana-plugin install https://github.com/seadiaz/computed-columns/releases/download/x.y.z/computed-columns-x.y.z-a.b.c.zip

From Docker Image:

kibana-plugin install https://github.com/seadiaz/computed-columns/releases/download/x.y.z/computed-columns-x.y.z-a.b.c.zip

Roadmap

Numeric data validation.
Hidden columns format validation.

development

See the kibana contributing guide for instructions setting up your development environment. Once you have completed that, use the following npm tasks.

npm start

Start kibana and have it include this plugin
npm start -- --config kibana.yml

You can pass any argument that you would normally send to bin/kibana by putting them after -- when running npm start
npm run build

Build a distributable archive
npm run test:browser

Run the browser tests in a real web browser
npm run test:server

Run the server tests using mocha

For more information about any of these commands run npm run ${task} -- --help.

computed-columns's Issues

Enhancement : set "Data" as visualization type

Today, standard "Data Table" visualization has "Data" as visualization type.
But "Computed Columns" visualization has "Other" as visualization type.
It would be nice to set same visualization type than standard "Data Table".

Upgrade to Kibana 6

Any plans on moving this plugin up to version 6?

Does not work with Kibana 5.4.0

I have updated package.json to set 5.4.0 version.
But when I launch the plugin, there is no table displayed, but instead a blank screen.
And I have the following error in browser console :

Error: hiddenColumns is undefined

would you mind to add a gif

can not use in kibana 5.3.0

no result in new column.
can you fix that.

Bug : incompatible with "Split Table" mode

When I add an aggregation bucket, if I choose "Split Table" option, then the resulting visualization is a "blank screen" :

In my browser console, I get the following error :

Dots in linechart after enabling computed-columns

Hi there,
I like your plugin very much.

However, if I enable it I have a strange side effect on linecharts: blue dots are appearing.
I cannot remove nor can change the color of the dots.
If I remove the plugin, the dots are gone; very curious case.

I use the following steps for including the plugin in my Dockerfile file:
~snip
ADD plugins/computed-columns /kibana/plugins/computed-columns
RUN cd /kibana/plugins/computed-columns && npm install
~snip
Compilation succeed and I can use the your plugin without any further issue.
This applies to all versions I have tried 5.1.2, 5.2.0, 5.3.2, 5.4.0.

Any clue?

col[4] is always equal to 2.718

If there are at least five columns, then col[4] (corresponding to the 5th column) is always equal to 2.718.

For example, see this screen shot for a trivial example in which the first column is a simple count metric, and each of the next four calculated columns has a formula that points to the immediately preceding column.

I've reproduced this result both when the 5th column is populated by a metric in the Data tab and when it's populated by a computed column in the Options tab.

My temporary workaround is to treat the 5th column as a dummy column and add it to the hidden columns list.

installation issue

I am trying to install the plugin manually, and I get this message :

ERROR in ../plugins/computed-columns-master/public/computed-columns-vis.j

Module not found: Error: Cannot resolve module 'expr-eval' in C:\HOMEWARE
kibana\plugins\computed-columns-master\public
@ ../plugins/computed-columns-master/public/computed-columns-vis.js 25:1

Do you know what is it due to?

Bug : incompatible hide column in "Split Table" mode

When I add an aggregation bucket, if I choose "Split Table" option and I hide a column then the resulting visualization is a "blank screen" .

I don't have any console message.

Incompatibility with Kibana 5.5.0

Hi,

I download : computed-columns-0.6.0-5.3.3.zip
I modify package.json to set kibana version to 5.5.0
I install the updated zip in Kibana 5.5.0 => it works fine : "Plugin installation complete"
Then, I start Kibana => no error
But when I access Kibana in my browser, I get the following fatal error :

 Fatal Error
