Thank you for choosing SupportBee's Postfix plugin. This plugin
- Monitors the sizes of Deferred, Bounce, Active, Incoming, Hold and Corrupt queues of Postfix
- Automatically alerts you if the Deferred or Bounce queues grow large (> 100 mails)
- Python 2.6 or Python 2.7 and the
pippackage manager (
pipis required for installation)
- The plugin uses the
postconfcommand and a few other commands to monitor the sizes of Postfix's queues. So, the plugin has to be installed as
rootand also on the same server as the Postfix instance.
root, run the following commands
Install Python 2 and the
pip package manager
apt-get update apt-get install python python-pip
You may also have to install the
apt-get install python-dev
Install the plugin itself
cd ~ git clone email@example.com:SupportBee/newrelic-plugin-agent.git cd newrelic-plugin-agent git checkout postfix_support pip install -e `pwd`
Create the config file
mkdir -p /etc/newrelic/ wget https://gist.githubusercontent.com/nisanth074/254682efea9131179e5cedd490b84b46/raw/b1b97fbf5541f7b166e27db288c86b3b1e4133cb/newrelic-plugin-agent.cfg
and add your New Relic license key to the config file
sed -i -e 's/YOUR_NEWRELIC_LICENSE_KEY/youactualnewreliclicensekey/g' newrelic-plugin-agent.cfg
Create the log directory
mkdir -p /var/log/newrelic-plugin-agent
And start the plugin
newrelic-plugin-agent -c /etc/newrelic/newrelic-plugin-agent.cfg
You can also start the plugin using init
cd /etc/init.d/ wget https://raw.githubusercontent.com/SupportBee/newrelic-plugin-agent/f6f83c57297405be912ce968778665053ad9b4cc/etc/init.d/newrelic-plugin-agent.deb -O newrelic-plugin-agent /etc/init.d/newrelic-plugin-agent start update-rc.d newrelic-plugin-agent defaults
The benefit with using init is that init will automatically start the plugin if you reboot your server anytime
Once you start the plugin (either directly or using init), wait for a few minutes, visit the New Relic Plugins product and go to the Postfix tab. You should see your server in the list of Postfix instances in that tab. If you don't see a Postfix tab or don't see your server in the list of Postfix instances, check the plugin's log file
/var/log/newrelic/newrelic-plugin-agent for errors.
If you've migrated to the new New Relic Alerts product, automatic alerts won't work. Fortunately, its fairly easy (and also more flexible) to just setup these alerts yourself. Visit the New Relic Alerts product, go to the "Alert policies" section and setup an Alert policy for Postfix. You can use the follow metrics in the Alert policy conditions
