We don't really know if the application server or the database server portions of this configuration will "max out" first on this box. We have the ability, on pre-clustered versions of Cosmo, to separate the database onto a separate machine, yielding a 2-box cluster. Beyond that, we will (likely) need development support to properly support a very large user population.

Address core issues needed to collect base metrics
Technically, it's about more than the hosted service metrics; the overall community metrics are important to track and integrate too.
There's a few existing codebases which will likely be updated, integrated, and/or rewritten.
Metrics-related features can be rolled out incrementally.
Effort required pretty much scales linearly with the number of metrics and reports implemented (once a base infrastructure for analysis is complete).
2007-02-05: Preview metrics list drafted
2007-02-15: osaf.us has at least two metrics being regularly submitted to time-series web service
2007-02-20: Metrics infrastructure running regularly to produce updates
2007-03-05: Metrics available on dashboard
Launch+20d: Improved dashboard
Now
2h: Create metrics VM
Define "core management" metrics (list of 5)
Later
8h: Update the prototype time-series web service to CherryPy 3.0
Define full list of preview metrics available
15h: Build lightweight, dynamic, Python dashboard framework
8h: Write prototype code to parse Cosmo 0.6 access log
This work is a little behind; we should already have a shortlist of needed metrics agreed upon.
It's a little hard to specify properly until one really sees the data produced by new-logging-style Cosmo 0.6 in production.
More work is necessary to distinquish "metrics" (single numbers) from "reports" (tables/drill-down)
Are we ok with a fully-public metrics system?
Running regularly
Some counts of daily visitors broken down by user profile
A dashboard page is available to see the resulting analysis
(Strawman) list of "core management" metrics: Total number of unique visitors this week (broken down by category) Number of signups this week Number of Chandler downloads Retention analysis (users still using after 30/60/90/180/360 days of signup)
Dashboard has two base features: a graph of the "recent" history of the monitored metrics, and an ability to retrieve the history in a CSV format.
(Strawman) list of "preview" metrics: - People chandler users per week casual collaborators per week consultative users per week standalone users per week interop users per week number of signups per day percentage accesses by various clients - Traffic total hits per day total bandwidth (in/out) per day - Community number of Chandler downloads per week
Metrics are built on top of each other. From raw information, some "base" metrics are calculated. By combining (addition, subtraction, multiplication division, statistics, time analysis) the base metrics, additional metrics ("derived metrics") are calculated. All metrics carry units, which carry all the semantics and context of each metrics.
The hosted service metrics framework consists of three main components: Collection scripts Time-series web service * Dashboard
Most metrics are based on a time-series, which means measurements taken over time. Time-series metrics have handy properties, like being easy to visualize (ie, turn into graphs). They are useful for spotting trends that are important to product and strategic management.
We are very interested in "how many people are using our services", this lets us measure our impact on the public and guides our potential for sustainability. The most interesting metrics will therefore revolve around usage, people, frequency, and user profiles.
If the guiding principle is to "count people", propose core metric is "number of visitors per week", broken down into major user profiles:
chandler users per week
casual collaborators per week
consultative users per week
standalone users per week
interop users per week
So primary tenets for Preview metrics are:
Counting number of people using the system, matching user profiles, is a requirement
Community metrics should be revamped before Preview
Retention rates are very important to overall management, but complicated to implement. A "number of people using this week divided by total number of accounts signed up" will need to be included to serve as a primitive retention metric.
Two critical scaling factors are: 1) rate of updates, and 2) rate of synchronization. Rate of synchronization is hard, and we know what the default is for Chandler at least. But "average number of changes per day" should be included in Preview metrics.
Additional dimensions:
Change of events vs change of other stamps
Read vs writes
Authenticated versus anonymous
Recency, frequency, depth
Bandwidth
Performance
Low hanging fruit:
total hits per day
total bandwidth
total accounts accessed per day
chandler users per day
anonymous hits per day
percentage breakdown of chandler users by OS/platform
percentage breakdown of chandler user by version ID
percentage breakdown of all user agents
percentage breakdown by top-level domain
percentage of users from domains "probably" outside US
number of emails submitted to support queue
number of signups per day
number of authenticated logins per day
average number of items per collection
average number of collections per user
Important, non-trivial:
retention
consultative, standalone, mashup usage percentages
depth, average session length/ops
number of updates via chandler per user
getting user counts vs hit counts (interop users per day kinda hard)
weekly views of all "per day" metrics, in order to smooth daily fluctation, and better match spread-out usage patterns.
number of casual collaborators per chandler hub user
Need platform support:
Add authenticated user to Tomcat access_log
Clear marker for successful logins
Clear marker for anonymous access to collection
Clear marker for Chandler update
Clear marker for via-web-UI update
Clear marker for names of people using Cosmo UI
Implementations:
chandler visitors per day: distinct accounts accessed with authenticated access users with chandler user-agent
casual collaborators per day: "entry" urls followed using anonymous authentication to shared collection
consultative users per day: distinct accounts accessed with authenticated access with cosmo ui who have accessed with a chandler-user agent in the last 7 days
standalone users per day: distinct accounts accessed with authenticated access with non-chandler user-agent who have not accessed with a chandler-user agent in the last 7 days
interop users per day: distinct authenticated accounts acccess with non-chandler user agents, or maybe all accesses to non-cosmo UI URLs
retention: number of users who have had an access with 30 days of signup, 60 days, 90d, 180d, 1y

Plain language
You own your data. We will provide mechanisms for you to retrieve the contents of any records or data you store in our service.
You can't sue us if we lose or corrupt your data, or if you can't get to your data.
We will not sell, rent, or otherwise make available your account information, data, or transaction history to anyone. Except where required to be handed over by law.
We can revise these policies.
You won't do things that endanger the viability of the service for others. This can mean "too much" usage, illegal usage, attacks on other accounts, etc.
Standard terms: Jurisdiction, Severability, Limitations of liability to fees paid, No Warranty, Indemnification, Entire Agreement, Internet not under our control, Assignment,

Provide product management, business development, and promotional insight by showing core metric trends visually on a web page.
Business aphorism: you can't manage what you can't measure.
The dashbaord provides the primary presentation of metrics maintained for the hosted service. The dashboard selects a few "core metrics" and presents them well and in context with other metrics.
Of the hundreds of possible metrics, it's inevitable that management attention and focus become centered on a smaller shortlist of core metrics. These receive priority attention in the dashboard.
Need a backend implementation of core metrics before presentation.
Traditionally, we're talking graphs or tables kept up-to-date on an HTML page.
There's a basic daily and weekly analysis codebase available that will likely be reused.
Open to the public or password-protected only? Would love to just do it all public and retract some later if needed.
Need a graphing engine.
Inclined to keep around all source data and generate graphs as-needed. Avoid RRD implementation (round-robin) data backend for now (and thus probably avoid RRD graphs).

To upgrade to a new production instance of Cosmo on osaf.us:
Edit /home/osaf.us/conf/cosmo-service-instance.conf. Find the old production configuration stanza, and mostly cut-and-paste it into a new instance definition. You will need to decide:
instance root (/home/cosmos/INSTANCE is the standard)
Cosmo and Snarf SVN URLs and revision numbers
MySQL database name
Tomcat HTTP port number (and shutdown port number)
Reverse proxy configuration Save the configuration file.
Create the new instance: sudo -u cosmo /home/osaf.us/bin/manage build,start INSTANCE_NAME
Check in changes into osaf.us svn repository.
A data-preserving update is a separate procedure, which needs further exploration and definition in this runbook.
To update an instance's configuration:
Edit /home/osaf.us/conf/cosmo-service-instance.conf. Tweak what you need, probably a port number or something.
Run: sudo -u cosmo /home/osaf.us/bin/manage stop,config,start INSTANCE_NAME
You can also reconfigure multiple instances in one command by placing additional instance names on the bin/manage command line, spearated by spaces. This is useful for taking one instance off the proxy_port config, and putting another one into that config quickly.
