Parallel Piper

Simple mobile web app for sending data to a Splunk HTTP input. It measures the device motion and sends an event with the intensity of the motion to Splunk.

Build/Deploy

1. Install NPM deps

npm install

2. Run webpack build

Run build.sh in the source directory.

$ sh build.sh

The following environment variables need to be defined for specifying the Splunk server running the HTTP input.

• PP_SPLUNK_HOST (default is "localhost")
• PP_SPLUNK_PORT (default is 8088)
• PP_SPLUNK_SSL (default is false)
• PP_SPLUNK_TOKEN (required) token for the HTTP input (See Splunk Setup below.)

Then run the webpack build:

PP_SPLUNK_TOKEN=cafecafecafecafe \
PP_SPLUNK_HOST=my.host.com \
./node_modules/webpack/bin/webpack.js -p

This generates all the page, JS and all the static content in the dist directory. Simply copy it to a webserver-exposed folder.

Splunk Setup

To enable the splunk HTTP Event Collector and create a token follow the instructions posted here:

http://docs.splunk.com/Documentation/Splunk/latest/Data/UsetheHTTPEventCollector

Once you have your token make sure you update your PP_SPLUNK_TOKEN in the previous section.

Parallel Piper makes use of cross-origin resource sharing which requires you to enable CORS on the HTTP event collector.

To do this edit your $SPLUNK_HOME/etc/system/local/server.conf and add the following.

[httpServer]
crossOriginSharingPolicy = *

If you wish to restrict cors calls to a specific domain replace the asterix with the domain name your are hosting Parallel Piper on.
