  • Where are we in our journey with Splunk?
    1) Identify best of breed software (based on ~30 specific requirements)
    2) POC - Limited term license
    3) Infrastructure build out for scale
    4) -- current -- Bring the data
    5) -- this summer -- Splunk PS to kick-start
  • So what did all the buzz in the video mean in terms of usage?
    April 2014 key highlights.
    Each item driving more events into logs.
  • POC was EOL server and all roles on 1 box.

    Prod deployment taking advantage of physical and virtual hosts.
  • Now that data is being indexed, I want to answer questions - quickly.

    There is a lot of data available to answer simple questions.

    Generation of NOW. Look at the time table to power a chart. – EACH TIME IT LOADS

    What have I learned as a new customer of Splunk to reduce or remove "Loading..."
  • 1) Understand who is consuming the dashboards & visualizations
    - 3 key elements to determining what optimizations you can use.
    2) Walk through the panel types
    3) Other methods for answering the tuff questions faster

    ---
    Dashboards, I don’t want to wait minutes or hours to view data that I review frequently.
    1 Basic saved searches that are saved as dashboard panels are “in-line” searches. They are performed each time a dashboard/panel/chart is called. (super slow)
    2 Saved searches using “accelerate this search”, faster but searches are still performed each time.
    3 Saved searches using scheduled – faster, but the delta time from when the search was performed is slow. You do lose flexibility to wander outside your scheduled search terms.
    4 Using a summary index – fast
    5 Partition data that you need real-time / inline searches
    6 Use “fast search”
    7 Evaluate expensive operations using inspect
    * real-time search – keep their timespan limited by # of events it must crawl – beyond 15min, what’s the point? (users of splunk typically don’t have rights to perform real-time.
  • Lastly – If you suspect there are inefficiencies with your search – use the inspector!
    2 easy ways to launch.
    Can tell you if you have a slow index server.
  • We are hiring!
  • This is the end-card.
