In this change: - removing pylons contrib - removing mysqldb contrib - updating minimum versions of flask (>=1.0), gevent (>=1.1) Signed-off-by: Alex Boten <aboten@lightstep.com>

USAGE = """
|
|
Execute the given Python program after configuring it to emit Datadog traces.
|
|
Append command line arguments to your program as usual.
|
|
|
|
Usage: [ENV_VARS] ddtrace-run <my_program>
|
|
|
|
Available environment variables:
|
|
|
|
DATADOG_ENV : override an application's environment (no default)
|
|
DATADOG_TRACE_ENABLED=true|false : override the value of tracer.enabled (default: true)
|
|
DATADOG_TRACE_DEBUG=true|false : enabled debug logging (default: false)
|
|
DATADOG_PATCH_MODULES=module:patch,module:patch... e.g. boto:true,redis:false : override the modules patched for this execution of the program (default: none)
|
|
DATADOG_TRACE_AGENT_HOSTNAME=localhost: override the address of the trace agent host that the default tracer will attempt to submit to (default: localhost)
|
|
DATADOG_TRACE_AGENT_PORT=8126: override the port that the default tracer will submit to (default: 8126)
|
|
DATADOG_SERVICE_NAME : override the service name to be used for this program (no default)
|
|
This value is passed through when setting up middleware for web framework integrations.
|
|
(e.g. flask, django)
|
|
For tracing without a web integration, prefer setting the service name in code.
|
|
DATADOG_PRIORITY_SAMPLING=true|false : (default: false): enables Priority Sampling.
