Dashboard Digest Series – Episode 5: Maps!
“A map does not just chart, it unlocks and formulates meaning; it forms bridges between here and there, between disparate ideas that we did not know were previously connected.” ― Reif Larsen, The Selected Works of T.S. Spivet
Welcome to Episode 5 of the Dashboard Digest series!
Maps play a critical role in visualizing machine data in almost any industry for thousands of use cases. We’ve been continuously adding more mapping functionality to Splunk and with the recent addition of Custom Visualizations in Splunk 6.4 you (the community) have too! This is exciting news as I’ve noticed many times the first panel on a dashboard that draws attention is a map. The best part is that each of these displays …
Dashboard Digest Series – Episode 3
Welcome to Episode 3 of the Dashboard Digest series! At Splunk we love to eat our own dogfood so in this episode we will see a dashboard showing energy and water usage at Splunk headquarters in San Francisco! Additionally you’ll see a few new custom visualizations that became available for use in Splunk 6.4 as well as use of the Machine Learning Toolkit.
Purpose: Display and analyze building energy and water usage. Use machine learning to forecast energy usage, detect outliers and look for anomalies.
Splunk Version: Splunk 6.4 and above
Data Sources: Sensor data in JSON format coming from Aquicore devices.
Apps: Machine Learning Toolkit, Water Gauge Visualization, Calendar Heatmap Visualization
Summary of tips/tricks used:…
Can you SPL?
A couple of weeks ago at .conf2016 we conducted our 2nd annual SPL’ing Bee and it was just as exciting as the year before. We had over 30 contestants, close to 100 spectators and a whole new set of challenging questions.
Here is a little background on how the SPL’ing Bee works.
During the SPL’ing Bee, contestants compete by using SPL to answer questions of a specific data set. To do this, contestants download and install the “Add-on for SPLBee App” on Splunkbase. This app allows each contestant to write a SPL query on a specific data set and submit their results to a master judging instance using a macro and a Splunk custom command called sendjobmeta created by …
Dashboard Digest Series – Episode 2: Part Deux
Before moving on to the next episode 3 I decided to do a part two of Episode 2 – Waves! The reason being is two-fold. 1) Splunk Enterprise 6.5 was recently released and 2) Hurricane Matthew had quite the effect on some of these buoys/stations. See the original blog post here: Dashboard Digest Series – Episode 2
Purpose: Display meaningful statistics on NDBC buoy information in historical and real-time. Easily drilldown, aggregate and visualize data from 1000s of buoys transmitting information.
Splunk Version: Splunk 6.5 and above for table coloring
Data Sources: Polling NDBC RSS feed that produces JSON payload
Apps: Add-on for NDBC, Custom Cluster Map Visualization, Clustered Single Value Map Visualization, …
Dashboard Digest Series – Episode 2
Welcome to the second episode of the Dashboard Digest Series! So what do we have for Episode 2? Waves!
The use case here was to display real-time and historical parameters and statistics from the National Oceanic and Atmospheric Administrations National Data Buoy Center or NOAA NDBC for short. Thanks to an add-on created by Julien Ruaux on Splunkbase, I was able to easily collect data from the NDBC’s data feed and start creating dashboards right away. While the NOAA NDBC site has it’s own dashboard (pictured right) I figured it might be useful to access and visualize the data in different ways through Splunk. That and eventually correlate the buoy data with other data sources.
Purpose: Display meaningful statistics …
Dashboard Digest Series – Episode 1
Welcome to the Dashboard Digest Series! Starting today you can look forward to a different dashboard (and sometimes a collection of dashboards) that was created to solve one of many hundreds of use cases in just about any industry in hopes of getting your creative juices flowing and show you the art of possible of what you can create with Splunk. Some upcoming examples you can expect in this series are depicted in the collage below.
Each post will contain information about the dashboard such as data sources involved, Splunk version, Apps used, and general purpose. This is a great way to see new features and learn about tips and tricks on how to create these dashboards!
So let’s get started!
The first …
If your plants could speak to you, what would they say?
I’m pretty sure mine would say “Hey Bozo, thanks for drowning me to death” or “Must… have… water… What is this, the Sahara?” Oh, and also “I hate it here, what’s it take to get some morning sun?”
I decided it was time to apply my inner nerd to reduce my plants suffering. That and happier plants mean a happier fiancé. Enter Splunk! The goal was:
- Keep track of moisture level in the soil.
- Determine best location for light intake.
- Combine current weather data, future forecasts and 1 and 2 above to create some machine learning models that predict when is best to water. (I’m still working on this part)
I shall call it… Operational Plantelligence! When first said aloud, …
Splunking Avalanches of Data
TLDR = Splunked some sensor data from a Thingsee data logger while skiing and sparked questions about avalanche safety. Dashboards of skiing data below if you don’t feel like reading.
We’ve heard it over and over again: the amount of data generated is growing exponentially. With the emergence of the Internet of Things (IoT), there is no doubt an avalanche of data (see what I did there?) coming. In fact, some say NOAA could be collecting as much as 800 terabytes of data a day, and storing over 100 exabytes by 2020. And that’s just one organization. The question we all have is how do we handle this data, no matter the structure, format, size, speed, schema, way it’s collected, …
Oooooooh, Shiny… Icons!
Who doesn’t love building “shiny” dashboards and getting the following reaction from their viewers? One trick to add some extra flare to your dashboards is replacing your single value rangemap icons with your own images that change color or to a different image depending on the value. This even includes animated .gif or svgs! For example the Operational Intelligence dashboard below shows one use case of single value icon replacements. In fact, the “Power” and “HVAC” icons on the bottom right are animated .gifs and both change color and spin faster according to the single value result. Cool eh? Let’s see how this is done so you can build your own! Note: This only works on 6.1.x and 6.2.x!
