Stats collection

General questions:

• What's more useful? Per feature or per instance (wikiid)
  • per feature is dream level, but wikiid is deki
  • is hostname good enough to do per instance?
• How to seprrate internal counts from actions that affect external requests
  • General facility to log certain prefixed headers at the socket membrane
• Does statsD or graphite or neither provide the ability to aggregate data on the folder (foo.bar) boundary?

Implementation

• Should be able to create StatsD logger statically like log4net logger
• Like log4net, by default it will have a null logger attached
• Can configure statsD server via app.config
  • Future
    • Add simple routing to support multiple servers
    • Add support for filtering

Feature level

Only requests that leave the server?

host.feature.{stat}

• bytes in
• bytes out
• exceptions out or status codes
• verbs?
• elapsed time
• requests/second

• elapsed
• db response
• exception count
