Previous Action Items
- bug 706912 - implement regression calculations - A*Team

- disable side by side staging - armenzg, jmaher

Status Reports
RelEng
- bug 724561 disabled side by side for tp5r and we now use --ignore-first everywhere (except Linux/Windows)
- bug 727823 enabling tp5r for Linux and Windows as well
- we enabled tp5r for Linux/Windows last week
- patches are ready to land
Metrics
- Comparing current Talos data collection and aggregation methods to other proposed methods
- Observed that the current data collection method has heavy carry-over effect (numbers increases over cycles)
- Longitudinal method is better (more stable/tighter around the mean)
- Propose new experiment
- Similar to pagecycles.cvs method, except this time, reboot for every page (100 reboots total)
- Make sure we run this experiment in the same environment as other previous experiments
Talos Changes
- updated more configurations
- moved pageloader into talos
Next steps:
- get pageloader to stop calculating statistics
- figure out what to do wrt sending all data to graphserver
Database Design
- A static copy of the graphs database is setup on s4n4.qa.phx1.mozilla.com and is accessible over mozilla MPT. We can use this as a hosted development database.
Graph Server
- bug 721884 - move talos writes to new graph server
- moving to repo http://hg.mozilla.org/users/rhelmer_mozilla.com/graphs (which is in sync with github)
- this is a step towards merging all the codebases - bug 721895
- change should go out this Friday: bug 727355
- old server (graphs-old) will still be up and functional, so talos writes can fall back if needed
- moving to repo http://hg.mozilla.org/users/rhelmer_mozilla.com/graphs (which is in sync with github)
jhammel - i will get a spec for graphserver-next db schema later today
