Simple poll mobile web app for sending data to a Splunk HTTP input. It allows people to answer simple multiple-choice questions on their mobile phone and have the results be displayed in a Splunk dashboard in real-time.
1) Update enviroment variables in build.sh
Change the environment variables to match your environment and configuration of the Splunk HTTP input.
# Hostname of the Splunk server with the HTTP input enabled
export PP_SPLUNK_HOST=localhost
# Port of the Splunk HTTP input
export PP_SPLUNK_PORT=8088
# `true` if SSL is enabled for the Splunk HTTP input
export PP_SPLUNK_SSL=false
# Splunk HTTP input token
export PP_SPLUNK_TOKEN=C0FFEE11-CAFE-CAFE-CAFE-C0FFEEC0FF33
For Splunk setup see below.
2) Build the mobile ap
Run build.sh
in the source directory.
$ sh build.sh
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.
Direct users to navigate to the URL of your webserver and have them answer the numbered questions. Each interaction wil send a new event to Splunk.
It's also optionally possible to specify the name of the poll (subject) and the number of questions as URL parameters:
http://my.webserver.com/poll?subject=Test%20Poll&count=12
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 = *
After Splunk 6.4 this setting moved to $SPLUNK_HOME/etc/system/local/inputs.conf
:
[http]
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.
