Creating an Agent for Drupal 7

[CommunityUser]

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.

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?

Matching Application and Tier.

Agent Connected Waiting for data... and waiting and waiting. 🙂

Have used a websirte copier to generate traffic.

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.

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,

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

Hey - Sorry for this trouble...

The agent.accountName and agent.accountAccessKey in /etc/php5/cli/conf.d/appdynamics_agent.ini were not correct.

I have updated them and restarted apache.

Still can't connect.

Ok... My problem is the accountname@customer# aren't inslalling.

Why?

[AD Thread Pool-ProxyControlReq0] 26 Jul 2017 13:32:46,047  INFO com.singularity.XMLConfigManager - XML Agent Account Info Resolver did not find account name. Using default account name [customer1]

The startop log for proxy.2017_07_26__13_32_45.0.log is attached.

What am I missing?

install script is as follows:

sudo ./install.sh -a=CustomerNumber@CustomerKey -e /usr/lib/php5/20121212 -i /etc/php5/apache2/conf.d ped19879 8090 wxt drupal localweb

or

sudo ./install.sh -a=CustomerNumber@CustomerKey -e /usr/lib/php5/20121212 -i /etc/php5/apache2/conf.d ped19879.CorrectDomain.com 8090 wxt drupal localweb

And the correct data seems to be in /etc/php5/apache2/conf.d appdynamics_agent.ini

Hi,

The recent logs shows 401 Unauthorized which comes when there is an issue with account name / access key. Could you please provide me following information from the environment over a SFTP account which I will share with you in a private message.

1. /etc/php5/apache2/conf.d/appdynamics_agent.ini file.

2. Zip of all the log files from agent logs folder.

3. Output of ps -ef | grep -i proxy command.

4. Screen capture showing account name and access key.

5. Output of phpinfo() from apache server with current agent configuration in place.

Please update on this ticket once you have uploaded all these details on the sftp account.

Best Regards,

Piyush

Ok - I have the files collected.
Please send private message with sftp creds.
Thanks

Hi,

Can you please check messages as I have already sent the SFTP details to you.

Recieved the creds at the alternate email addy I sent.

Hi Johnson,

The agent configuration in appdynamics_agent.ini file under /etc/php5/cli/conf.d and /etc/php5/apache2/conf.d folder are different. Could you please check attached screen capture to correctly find the account name and account access key which needs to be updated in both of these files.

The current screen capture you shared have the account details for End User Monitoring and not for the application agents.

Please get the correct details for account name and access key from controller UI, update those in /etc/php5/cli/conf.d/appdynamics_agent.ini and /etc/php5/apache2/conf.d/appdynamics_agent.ini file and restart Apache server. Please drive some load on the application and see if agent is now able to register and report to controller.

Best Regards,

Piyush

Hi piyush,

Spoke with an Engeneer re my trial.

I was looking at the User Experience Account Name and Key.

I went to the Account tab on the Licence screen in the Controller and used the Name and and Access Key located there in both the appdynamic_agent.ini files.

Agent is now sucessfully connecting to the Controller.

Thanks for your help.
