Brian Hicks's questions

I'm parsing Nginx logs into logstash with the following config:

input { stdin { type => "nginx"}}

filter {
    grok {
        type => nginx
        pattern => "%{COMBINEDAPACHELOG}"
    }
    date {
        type => nginx
        match => [
            "timestamp",
            "dd/MMM/YYYY:HH:mm:ss Z"
        ]
    }
 }

 output { stdout { debug => true debug_format => "ruby"}}

Except here's the problem: when I pass in a log with a @timestamp of "04/Sep/2012:12:44:16 -0500" I get (as the result timestamp) "2013-09-04T17:44:16.000Z". Wrong year. Is this a bug?

I have the following environment variable set (trying for a 12-factor app approach):

• PATH="/home/hope/env/bin:$PATH"

/home/hope/env/bin is the bin directory of a virtualenv, it has gunicorn and python in it, among other things. But running commands under this directory results in some funny behavior, namely:

• python works, and sys.executable returns "/home/hope/env/bin/python" (which python says this too.)
• gunicorn doesn't work, despite which gunicorn returning "/home/hope/env/bin/gunicorn".

Obviously to serve pages from this Django app, I need to be able to find gunicorn. I feel like I'm missing something basic, any ideas?

Edit: duh, here's supervisor's output: BACKOFF can't find command 'gunicorn'. Both python and gunicorn are 755 to the same user/group.

I'm using Opscode's application_python cookbook, and trying to deploy a Django application. I need to use Python 2.7 for this project, but it appears that the virtualenv creation is done with python2.6 by default, which I don't plan on installing on the system. Therefore, I get the following error when running chef-client:

[Fri, 08 Jun 2012 16:55:35 +0000] FATAL: Mixlib::ShellOut::ShellCommandFailed: execute[virtualenv --python=python2.6 /opt/apps/trippingbear/shared/env] (/var/chef/cache/cookbooks/python/providers/virtualenv.rb line 28) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '3'
---- Begin output of virtualenv --python=python2.6 /opt/apps/trippingbear/shared/env ----
STDOUT: The executable python2.6 (from --python=python2.6) does not exist
STDERR: 
---- End output of virtualenv --python=python2.6 /opt/apps/trippingbear/shared/env ----
Ran virtualenv --python=python2.6 /opt/apps/trippingbear/shared/env returned 3

I'm pretty (extremely) new to Chef, and haven't got an idea of how to change it. The default seems to be set with attribute :interpreter, :default => 'python2.6' in cookbooks/python/resources/virtualenv.rb. I've tried setting defaults both on my node and in the environment as the following, with no success:

default_attributes(
  "python" => {
    "virtualenv" => {
      "interpreter" => "python2.7"
    }
  }
)

I'm sure this is configurable, but I can't figure out quite how to do it. What am I setting incorrectly?

I'm setting up mongod to run in an /etc/init.d script. This may be a nitpick, but is there a way to avoid this?

# service mongod start
Starting mongod:
forked process: 19820
all output going to /log/location/mongod.log
[SUCCESS]

Instead, I just want to see:

# service mongod start
Staring mongod:              [SUCCESS]
