When running your PHP application in Azure Linux App Service, you may encounter availability or performance related issues.
PHP New Relic agent is one of the APM tools that can help to provide a better understanding of what may be causing these issues.
This article shows a demonstration of how to use New Relic agent to monitor your PHP application running in Linux App Service.
We can get the Newrelic API keys by navigating directly to https://one.newrelic.com/launcher/api-keys-ui.api-keys-launcher
Create "Ingest-License" key:
Copy the new create API key, save it in your local notepad. We will use this key later.
Go to https://one.newrelic.com/, login your New Relic, then click "Add more data"
Select PHP in "App monitoring"
Go "Begin Installation" -> "PHP standard installation"
Provide your application name and select "apt".
Newrelic will provide you the installation commands
Let's put all the commands into a bash script file.
#!/bin/bash echo 'deb http://apt.newrelic.com/debian/ newrelic non-free' | tee /etc/apt/sources.list.d/newrelic.list wget -O- https://download.newrelic.com/548C16BF.gpg | apt-key add - apt-get update apt-get -y install newrelic-php5 NR_INSTALL_SILENT=1 newrelic-install install sed -i -e "s/REPLACE_WITH_REAL_KEY/<your Newrelic API key>/" \ -e "s/newrelic.appname[[:space:]]=[[:space:]].*/newrelic.appname=\"<your application name>\"/" \ -e '$anewrelic.distributed_tracing_enabled=true' \ $(php -r "echo(PHP_CONFIG_FILE_SCAN_DIR);")/newrelic.ini echo '>>>check /usr/local/etc/php/conf.d/newrelic.ini' grep newrelic.license /usr/local/etc/php/conf.d/newrelic.ini grep newrelic.appname /usr/local/etc/php/conf.d/newrelic.ini
1) In line 9, replace <your Newrelic API key> with your Newrelic API key.
sed -i -e "s/REPLACE_WITH_REAL_KEY/9c6fxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxNRAL/" \
2) In line 10, replace <your application name> with your Azure App Service name.
-e "s/newrelic.appname[[:space:]]=[[:space:]].*/newrelic.appname=\"myphpwebapp\"/" \
3) To confirm Newrelic being successfully installed, I added Line 14-16 to check newrelic.ini being configured as expected.
In your Azure App Service WEBSSH, create /home/setupNewrelic.sh with the above contents.
Past all the script contents into it, then use ":wq" to save this file.
Go to your App Service Configuration portal to set "Startup Command", point it to your /home/setupNewrelic.sh
Enable your "App Service logs"
In your /home/LogFiles/xxxx_xx_xx_xxxxxxxx_default_docker.log file, you will see the Newrelic being installed during the boot up startup.
Go to https://one.newrelic.com/, click "Explorer" tab, in the "APM", we should see your java app showed up in the list. The Name should match your application name defined in your setupNewrelic.sh.
Monitor the Application performance Summary.
Check Errors and exceptions throwed by the PHP application
Check Service map and dependencies
Check Transactions, analysis most time consuming requests
Check Database performance
