Transcript
New monitoring systems (and why you should use experiment with
them) Matt Cottingham @mattrco
Web Operations (Allspaw et. al.) • Great overview of approaches
to ensuring the uptime of your services • Useful when I co-founded a startup
• Monitor systems, services and applications • Learn what is
expected for a system • See trends and patterns • Discover and alert on problems Monitoring metrics
What’s changed since?
What’s changed since? • Multiple deploys per day • Application
Performance Management • Breadth of IaaS/PaaS offerings • More applications (Microservices) • Anomaly detection • Containers...
What needs improving? • Handle ephemeral nodes • Thresholds are
still a pain • Manipulating data is still hard • Make useful for others in the business?
Some notable Go projects Heka (by Mozilla) • Data collection
and processing in use at Mozilla • Large no. input and output plugins • Logs as well as metrics • Lua sandbox for experimentation
Some notable Go projects Prometheus (by SoundCloud) • Tagged time
series • Query DSL
Some notable Go projects Bosun (by Stack Exchange) • Similarities
to prometheus • Run alerts against historical data! • OpenTSDB datastore
Some notable Go projects InfluxDB • Time series database •
Based on LevelDB
An experiment Anode (github.com/mattrco/anode) • Setting thresholds is boring, a
computer should do it • Inspired by heka and Etsy’s skyline • Thrown together in a few evenings
Building Anode Channels are a good fit for input, processing,
output
Building Anode https://github.com/dgryski/go-change
Inspiration
Heka in more detail • Sandbox allows you implement certain
plugin types at runtime • Change the .lua file, reload • Resources constrained • Low memory footprint (16KiB/plugin)
Go runtime statistics • expvars (in the standard lib) is
a thing that is useful
Where we want to be • Adrian Cockroft’s Velocity keynote
is full of good suggestions: https://vimeo. com/95064249
Thank you @mattrco
