[chef] Re: Newrelic application monitoring

[Mathieu Martin < >]

Sounds lime something I'd do with runit. And the env vars can be managed in a modular fashion with chpst -e (comes with runit).

In Python it is also installed as a package, and then runs as a wrapper around the python/django application.

To use the wrapper script when running a standalone WSGI server or web application, you will need to modify the existing startup command you use for that WSGI server or web application. At the same time, you must set environment variables to tell the wrapper script where the agent configuration file is located or what the license key is.

In general terms, if you you are currently executing your WSGI server or web application as:

command options

you would now need to run it instead as:

NEW_RELIC_CONFIG_FILE=newrelic.ini newrelic-admin run-program command
  options

The wrapper script is 'newrelic-admin' and is being run with the 'run-program' option. This is prefixing the complete existing command you used previously when starting your WSGI server or web application.

I thought someone might have already come up with a way to modify the supervisor config file in that manner.

Not sure how it's done in the python world.

But in the Ruby world, the NewRelic app monitoring is simply added as any other application gem (library). So it's available in dev with a useful dev mode. And it's automatically installed upon deployment by Bundler.

Is there something similar in the Python world?

And you're right, server monitoring is a breeze to install. And very useful.

Hi --

Anyone have experience adding newrelic?

I'm adding newrelic monitoring to an application that uses
django/gunicorn/supervisor.
First, I notice that there are three opscode newrelic cookbooks:
newrelic_monitoring
newrelic-ng
newrelic

It looks like the newrelic-ng is the only one that includes application,
as opposed to system, monitoring.  Is that correct?
Also, it looks like it doesn't automatically setup monitoring.  I think
you still have to modify the supervisor template in order to run the
newrelic wrapper script.
That doesn't look to hard, but I don't want to re-invent the wheel if
someone else has already done this.
An example would be useful.

I'm also going to add the newrelic server monitoring, but that looks
simple since it's relatively independent.

Thanks!
Liam
