Creating an Agent for Drupal 7

[fgjohnson]

Hi,

I have the controller installed and running.

I can create a database agent, install it on my Drupal server and see some database data.

How do I create an agent that can monitor my Drupal Application?

Thanks

Hi,

If you are running PHP on the server, you can install the PHP agent and monitor it. Please go through the documentation link at https://docs.appdynamics.com/display/PRO43/Install+the+PHP+Agent for more information on the agent installation.

Best Regards,

Piyush

Ok,
Went through the Docs.
Used this to install

sudo ./install.sh -a=xxx@yyy -e /usr/lib/php5/20121212 -i /etc/php5/cli/conf.d 8090 Drupal7 phpTier myNode
Output seemed successful... but can't see it in the Controller.

Writing '/home/developer/php-agent-2/appdynamics-php-agent/appdynamics-php-agent/php/conf/appdynamics_agent_log4cxx.xml'
Writing '/etc/php5/cli/conf.d/appdynamics_agent.ini'
Writing '/home/developer/php-agent-2/appdynamics-php-agent/appdynamics-php-agent/proxy/conf/controller-info.xml'
rm -f "/usr/lib/php5/20121212/appdynamics_agent.so"
ln -s "/home/developer/php-agent-2/appdynamics-php-agent/appdynamics-php-agent/php/modules/appdynamics_agent_php_5.5.so" "/usr/lib/php5/20121212/appdynamics_agent.so"
Writing '/home/developer/php-agent-2/appdynamics-php-agent/appdynamics-php-agent/proxy/runProxy'
Do I need to create matching agent place holders in the Controller or should it auto find?

[fgjohnson]

Matching Application and Tier.

Agent Connected Waiting for data... and waiting and waiting. :-)

Have used a websirte copier to generate traffic.

See image.

Attached php -i output.

installed the agent with the following syntax:

./install.sh -a=12345-ss-abcdef-12gg23w33ewe@sdfsdf-sdfsdf-sdfsdf-sfs-fsfdsfsd -e /usr/lib/php5/20121212 -i /etc/php5/apache2 hostna.e.domain.com 8090 Drupal7 myTier myNode

Ideas?

Hi,

Please try with follwoing command after replacing the proper placeholders for account name, access key, controller host and port.

./install.sh -a=ACCOUNT_NAME@ACCESS_KEY -e /usr/lib/php5/20121212 -i /etc/php5/apache2/conf.d CONTROLLER_HOST CONTROLLER_PORT Drupal7 myTier myNode

Hi,

After the agent installation, please restart the Apache server and drive some load on the application. If the issue still persists, please provide us the output of phpinfo() from apache.

Best Regards,

Thanks Piyush,

Attached phpinfo.txt created with phpinfo.php in docroot.

Yesterday I was using 4.3.3.7

I uninstalled everything and tried with 4.3.3.8... Can't even get a connection now. :-(

Here's the command and output, as root, to install the agent.

./install.sh -a=ACCOUNT@KEY -e /usr/lib/php5/20121212 -i /etc/php5/apache2 ped19879 8090 Local_WxT Drupal localweb

Hi,

The latest phpinfo shows that the agent is installed and hooked in but it looks like one of the configuration parameter might be an issue. Could you please check specifically for accountName configuration parameter which seems to be wrong. You can verify these agent config details in /etc/php5/apache2/conf.d/appdynamics_agent.ini file. Could you also please check if there are any log files generated in /home/developer/appdynamics-php-agent/logs folder which might give some hint on the issue.

Best Regards,

Piyush

I verified the
agent.accountName

agent.accountAccessKey

in /etc/php5/apache2/conf.d/appdynamics_agent.ini.
They are the same there and in the Controller Licence screen.
in the proxy log


Could not connect to the controller/invalid response from controller, cannot get initialization information, controller host [hostname.domain.com], port[8090], exception [null]

I am able to ping both the controller hostname.domain.com and hostname from the server to be monitored...

... in the agent log
