$ sudo /sbin/service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Syntax error on line 247 of /***/apps/web/webfarm/***.com-httpd.conf: Syntax error on line 5 of /***/apps/AppDynamics/webagent/appdynamics_apache_agent.conf: Cannot load /***/apps/AppDynamics/webagent/sdk_lib/lib/libappdynamics_native_sdk.so into server: libzmq.so.3: cannot open shared object file: No such file or directory

The documentation on this agent's installation is bare bones at best. So I'm not suprised you ran into this issue. 

The file you're looking for is included in the agent package (at least it is through 20.10)
It's located in the [agentroot]/sdk_lib/lib/ direcotry.

You can either copy the file to the /usr/lib or /usr/lib64 directory (depending on your OS) or you can create a symlink that links back to the agent path.

This will resolve your issue.
