Class: profile::arclamp::processor

Provision Arc Lamp, which processes PHP stack traces and generates SVG flame graphs. This profile also provisions a static HTTP server exposing the trace logs and SVG flame graphs.

See also profile::webperf::site, which provisions a reverse proxy to expose the data at <performance.wikimedia.org/arclamp/>.

Original launch task: phabricator.wikimedia.org/T194390.

Parameters

redis_host

Address of Redis server that is publishing stack traces.

redis_port

Port of Redis server that is publishing stack traces (usually port 6379).

errors_mailto

Email address to send errors to

compress_logs_days

How many days to wait before compressing logs.

retain_hourly_logs_hours

How many hourly captures to retain on local disk.

retain_daily_logs_days

How many daily captures to retain on local disk.

Parameters:

  • redis_host (Stdlib::Fqdn) (defaults to: lookup('profile::webperf::arclamp::redis_host'))
  • redis_port (Stdlib::Port) (defaults to: lookup('profile::webperf::arclamp::redis_port'))
  • errors_mailto (String) (defaults to: lookup('profile::webperf::arclamp::errors_mailto'))
  • compress_logs_days (Integer) (defaults to: lookup('profile::webperf::arclamp::compress_logs_days'))
  • retain_hourly_logs_hours (Integer) (defaults to: lookup('profile::webperf::arclamp::retain_hourly_logs_hours'))
  • retain_daily_logs_days (Integer) (defaults to: lookup('profile::webperf::arclamp::retain_daily_logs_days'))
  • swift_accounts (Hash[String, Hash]) (defaults to: lookup('profile::swift::accounts'))
  • global_swift_account_keys (Hash[String, Hash]) (defaults to: lookup('profile::swift::global_account_keys'))
