The key to staying on top of your applications is to monitor them. For a little bit of extra monitoring help, Codeship users can easily notify New Relic about each deployment to an application with the following script. This allows users to analyze the correlation between their code releases and the performance of their application.

# !/bin/sh
# Notify New Relic about a new deployment
# You have to set the following environment variables in your project configuration
# (NEW_RELIC_APP needs to match an existing Application Name in the New Relic APM)
# You have the option to define a revision, a description, and a changelog with the following environment variables
# (Defaults are: description = CI_MESSAGE, revision = CI_COMMIT_ID, and an empty changelog).
# * NEW_RELIC_DESCRIPTION  (65535 characters or less)
# * NEW_RELIC_REVISION  (127 characters or less)
# * NEW_RELIC_CHANGELOG  (65535 characters or less)
# Check required parameters
NEW_RELIC_API_KEY=${NEW_RELIC_API_KEY:?'You need to configure the NEW_RELIC_API_KEY environment variable!'}
NEW_RELIC_APP=${NEW_RELIC_APP:?'You need to configure the NEW_RELIC_APP environment variable!'}
#sanitize semicolons, remove newlines, and replace multiple spaces with a single space
NEW_RELIC_APP=$(echo ${NEW_RELIC_APP//;/%3B}|sed ':a;N;$!ba;s/\n/ /g'|tr -s ' ')
NEW_RELIC_DESCRIPTION=$(echo ${NEW_RELIC_DESCRIPTION//;/%3B}|sed ':a;N;$!ba;s/\n/ /g'|tr -s ' ')
NEW_RELIC_REVISION=$(echo ${NEW_RELIC_REVISION//;/%3B}|sed ':a;N;$!ba;s/\n/ /g'|tr -s ' ')
NEW_RELIC_CHANGELOG=$(echo ${NEW_RELIC_CHANGELOG//;/%3B}|sed ':a;N;$!ba;s/\n/ /g'|tr -s ' ')
curl \
    -H "x-api-key:${NEW_RELIC_API_KEY}" \
    -d "deployment[app_name]=${NEW_RELIC_APP}" \
    -d "deployment[description]=${NEW_RELIC_DESCRIPTION}" \
    -d "deployment[revision]=${NEW_RELIC_REVISION}" \
    -d "deployment[changelog]=${NEW_RELIC_CHANGELOG}" \
    -d "deployment[user]=${CI_COMMITTER_USERNAME}"

Important Notes

As a prerequisite, install the New Relic Agent on the server that hosts the application. You’ll need to restart the application as well.

New Relic will highlight deployments on the Overview page by inserting a pointer in the time line. As you can see in the screenshot below, each vertical black line indicates a deployment. We’ve also highlighted the annotations to show where each environment variable is visible on the Overview page.
