collective.newrelic 1.0.9

Introduction

This package offers instrumentation for NewRelic ( http://www.newrelic.com ). Currently the catalog-tool, transformchains and zope-events are instrumented. A transform is included to support RUM (Real-User-Monitoring): it inserts small snippets of javascript at the top and bottom of the rendered pages. RUM does not work in the ZMI (Zope Management Interface).

Installation

You can add this egg ‘collective.newrelic’ to your eggs and it will pull in the ‘newrelic’ egg too.

[buildout]

# either pin versions as shown below...
versions=versions

[versions]
newrelic = 2.6.0.5
repoze.xmliter = 0.5
# update to 1.0.9 on next release:
collective.newrelic = 1.0.8

# ...or allow picked versions and risk breakage on product updates
#allow-picked-versions = true

parts +=
    newrelic

[newrelic]
recipe = zc.recipe.egg:scripts
eggs = newrelic

[instance]
eggs +=
    collective.newrelic

# make sure newrelic itself is enabled and set the path to your newrelic.ini file
environment-vars +=
    NEW_RELIC_ENABLED true
    NEW_RELIC_CONFIG_FILE ${buildout:directory}/newrelic.ini
    NEW_RELIC_ENVIRONMENT development

# when using supervisor, setting environment variables is slightly different:
#[supervisor]
#supervisord-environment=NEW_RELIC_ENABLED=true,NEW_RELIC_CONFIG_FILE=${buildout:directory}/newrelic.ini,NEW_RELIC_ENVIRONMENT=development

A number of additional settings can optionally be configured using environment variables, see http://docs.newrelic.com/docs/python/python-agent-configuration#environment-variables for details. Customizing your newrelic.ini file is more advised though, see below.

The NEW_RELIC_ENABLED and NEW_RELIC_CONFIG_FILE variables need to be set for the newrelic agent to work though.

Omitting NEW_RELIC_ENVIRONMENT variable will mean the [newrelic] part is loaded without additional [newrelic:YOURENVNAME] settings.

Please note: the newrelic package needs python >= 2.5. This package will not work on Plone 3.

Use

To enable the logging to newrelic.com, create an account at newrelic.com and get your license key. Create a ‘newrelic.ini’ file in the root of your project. Either by copying the template from this package or the newrelic package or run

$ bin/newrelic-admin generate-config YOUR-LICENSE-KEY newrelic.ini

This will create a newrelic.ini file in the current directory.

You might want to validate your generated file using newrelic-admin validate-config newrelic.ini

The default profile is ‘staging’, this can be changed in the __init__.py in the patches directory. You can change the default name of ‘Python Application (Staging)’ in the newrelic.ini file. To get sensible database-traces change

transaction_tracer.record_sql = obfuscated

to

transaction_tracer.record_sql = raw

Full class+function wrapping of an entire module

from plone.app import viewletmanager as plone_viewletmanager
from collective.newrelic.utils import wrap_module_classes_functions
class_function_modules = [plone_viewletmanager, ]
wrapped_methods = wrap_module_classes_functions(class_function_modules)
print len(wrapped_methods)

Single class wrapping

from zope.tal.talinterpreter import TALInterpreter
from collective.newrelic.utils import wrap_class_found_functions
wrapped_methods = wrap_class_found_functions(TALInterpreter)
print len(wrapped_methods)

Pin point precision wrapping of single class function

from zope.tal.talinterpreter import TALInterpreter
from collective.newrelic.utils import wrap_class_function
wrapped_methods = wrap_class_function(TALInterpreter, TALInterpreter.__call__)
print wrapped_methods
"TALInterpreter.__call__"
