Can we create a real-time web dashboard using Hunk or other app for a MongoDB source?

New Member

HI There,

I have a very specific requirement. I would like to know if we can use hunk to create a real time web dashboard which can be viewed by many people in the company on their desktop, devices, tabs etc? If hunk doesn't support this are there any other App in splunk which does this?

The data source is a MongoDB collection on a remote server running on Windows server 2012 which consists of Logs from an application.

Appreciate your help. Thanks.

Anil, it depends on what you mean by real-time. Hunk, with the hadoop provider or with the mongodb provider does not provide a real-time capability like Splunk Enterprise does. To be clear - you can run a Splunk Enterprise search in true "real time" and as soon as the incoming data hits a Splunk indexer, it is available for display on a dashboard or a tablet or whatever. With Hunk, we're executing map-reduce jobs in a hybrid model (against HDFS or nosql stores).

As I see it you have the following options.

  1. Use Hunk against MongoDB and simply run very frequent searches. We have seen customers run MongoDB searches once a minute like this, and the dashboard would update every minute. Perhaps that is close enough to real time for you.
  2. Use DB Connect, by installing a JDBC driver as shown here: http://www.unityjdbc.com/mongojdbc/setup/mongodb_jdbc_splunk.pdf. You can then use the dbquery command or you can index your MongoDB data in Splunk using a dbmon-tail and then truly use Splunk Enterprise's real-time capability.

If you truly have logs on a Windows server, there's no need to involve MongoDB at all here, by the way. You can simply use a Universal Forwarder to stream these logs in real-time to Splunk Enterprise, and get real-time visualization that way. You can even use the Splunk Mobile Access Server to serve up content to iPads.

The JDBC driver link in the message above is broken.
The correct (I think) link is this http://www.unityjdbc.com/mongojdbc/setup/mongodb_jdbc_splunk.pdf
