5 Things to Keep Monitoring After Black Friday / Cyber Monday

  1. 1. #MonitorAfterBFCM Five Things To Monitor After Black Friday / Cyber Monday Baron Schwartz - VividCortex
  2. 2. #MonitorAfterBFCM ● Last time I talked about specific things to validate pre-peak ● This time it’s five quick things to keep track of post-rush A Quick Win
  3. 3. #MonitorAfterBFCM The 5 Things 1. Keep an eye on disk space 2. Watch your latency changes 3. Check for performance regressions 4. Assess capacity ceilings 5. Plan for 2017
  4. 4. #MonitorAfterBFCM Code Slush ● Etsy and VividCortex both use a bit of extra caution while deploying in the holidays ● Hard “freezes” are counterproductive ● See my blog for more: https://goo.gl/5ojHPU ● This does add a bit more risk, though
  5. 5. #MonitorAfterBFCM 1. Watch Disk Space Full disks are one of the most common causes of outages. Did you make any changes while firefighting that you haven’t “cleaned up” or brought back into your Puppet/Chef config?
  6. 6. #MonitorAfterBFCM 2. Watch For Latency Increases ● Latency increase in an “important” query ● Use time-vs-time profiling with the Latency column in VividCortex ● Profiler > Queries by Total Time > Compare > look at Count, Latency
  7. 7. #MonitorAfterBFCM 3. Watch For Performance Regressions ● Increase in key parts of the workload ○ Use Profiler / Queries By Total Time ○ Configure alerts on query anomalies ○ Use long-term trending to spot gradual changes, e.g. “last 1 week” time range ● Newly released queries ○ Configure alerts on new queries that are significant ○ Use the Queries dashboard, toggle the “new” option

  9. 9. #MonitorAfterBFCM 4. Assess Capacity Ceilings We talked about the USL last time. You can download our ebook and Excel workbook to learn more and do your own modeling. Two new things you can now do: ● Model with higher real load than you previously were able to see ● See if your pre-peak predictions were right!

  11. 11. #MonitorAfterBFCM 5. Plan For 2017 A few things to do as you look ahead to 2017’s peak season: 1. Write down, take notes, save screenshots, etc a. VividCortex has a “time range bookmark” feature you might find helpful 2. Compare normal vs peak load a. What’s the ratio? b. What will you be able to project about 2017’s traffic based on 2017 normal?
