June SF Metrics Meetup

We have some fantastic speakers for our June Meetup: Rob Miller from Mozilla and Noah Kantrowitz. 

Our generous host is Mozilla. Arrive around 6:30pm to catch up with other quantifiers over food and drinks, talks start at 7:00pm. Space is limited, please RSVP.

Stream Processing Made Heka Easy

Rob Miller, Mozilla

Do you have servers? Are they running services? Are all of those servers and services producing data? Do you ever feel overwhelmed by all of that data, and wish that it were easier to parse, crunch, process, aggregate, watch, ship, and generate notifications based on that data? In this talk Rob Miller will show how Mozilla's Cloud Services team has been using their stream processing tool Heka to tame the firehose.

Is There An Echo In Here?

Noah Kantrowitz

For decades, audio engineers have been finding new and better ways to improve the quality of their signals. From the basics of high-pass and low-pass filters, to modern anti-feedback and echo cancellation algorithms, there is a huge body of work both academic and practical. Operations monitoring and metrics tools have also advanced rapidly in the last few years, leading to vastly improved alerting and general awareness of system health.

This is not without a downside, however. As anyone that has been on the receiving end of Nagios' flap detection or a graphite-induced pager storm can attest, the signal to noise ratio (itself an audio engineering term) has become a problem for many organizations. At heart a stream of audio data and a stream of metrics data are quite similar. This talk will explore some basic algorithms from Digital Signal Processing you can use to level up your monitoring systems!

We will be serving beer. Drinking is allowed for anyone age 21 or older.

    Thank you for great presentations and meetup! At the end of Noah's talk he gave some extras and mentioned wavelets, on which I want to comment that wavelets, just like sin-waves, is a set of orthogonal unit vectors that can be used to decompose the space. The advantage over sin-waves is that sin-waves spread the entire time span, so you have to use the window function if you want to look at some bound time interval, but wavelets are local in time so they are better suited to deal with signals that change over time.

    Anyone know if there is secure bike parking at this location (or more secure than locking up out on the street)?

    June 18, 2014

    • Rob M.

      There is a place inside where you can park your bike, yes.

    As always the talks will be recorded and published on our Vimeo channel

    This time we are going to try something new: Live streaming. Details about that later.
