Hi Mark,

Thanks for the command output. The PHP agent should be loaded. Kindly restart your apache/fpm process and verify the same using

php -i | grep zpa

Reg the permission error, kindly make sure the zpdp file has executable flag. To enable it, you can run the following command on the /opt/zpa/bin directory and try restarting the service. 

chmod +x zpdp  

Hope this helps, 

Hi Shrinivasan,

I have done the steps you said and it successfully installed. However, in the portal of site24x7 > APM it doesn't show any data and there's a message: 

No data collected for selected time period.

Hi Mark, 

If the zpa is not loaded in phpinfo it is possible that the agent is not registered properly or the apache/fpm service is not restarted. 

Kindly ensure if 

1. zpa.ini is present in the respective ini directory. You can find this using the following command

php -i | grep "Scan this dir for additional .ini files"

2. zpa.so copied is the corresponding API version. In your case, ensure you have copied "/opt/zpa/lib/zpa20170718.so" to "/opt/cpanel/ea-php72/root/usr/lib64/php/modules/zpa.so" . Note that the file name must be zpa.so in the destination directory (obtained from php -i|grep extension_dir). 

3. Restart the apache/php-fpm service. And verify again using "php -i | grep zpa" 

Kindly let us know if this works. 

Hi Shrinivas,

I still don't see any data in Site 24x7 after installing the PHP agent. 
I have followed all the steps mentioned here:
www.site24x7.com/help/apm/php-agent/install-php-agent.html

Still can't see Site 24x7 displaying any data for my webserver.

Please can you advise?

Thank you!

Hi Avani, 

Can you kindly confirm the following? 

1. zpdp service is running. You can verify it either by running "service zpdpsvc status" or "ps -ef | grep zpdp" 

2. You have restarted the apache/nginx/fpm services post installation. 

3. You can see the zpa module version when running "php -i | grep zpa"

If you are still seeing the issue, please check if the server is able to communicate to Site24x7 servers, by running "curl https://plusinsight.site24x7.com " . 

Also, please check the zpa*.log in /opt/zpa/logs directory to verify there are no errors in communication. 

Thanks for replying back.
1. zpdp is running

2. Yes, I restarted

3. Can see zpa version

Ran the curl command. Checked the logs in zpa*.log in /opt/zpa/logs directory. Here is what I can see in the logs:(Have filled the key/sensitive info with ****). I am not sure why do I get "error:no instance found".

Hi Avani, 

Regret the delay in getting back. 

Can you delete the following symbolic link files in /opt/zpa/lib/ directory and restart the zpdp service? 

libcurl.so / libcurl.so.4 

libssl.so

(Note that other files like libcurl.so.4.4.0/libssl.so.1.1 shall not be deleted)

After deleting these symbolic link files, kindly restart the agent service using either "service zpdpsvc restart" or (in /opt/zpa/bin/) "sh run.sh restart". 

Kindly let us know if this works. 

Thanks & Regards, 
Shrinivasan.
