Today I am going write a blog on how to Monitor Memory and Disk custom metrics and creating alarm in Ubuntu.
To do this, we can use Amazon CloudWatch, which provides a flexible, scalable and reliable solution for monitoring our server.
Amazon Cloud Watch will allow us to collect the custom metrics from our applications that we will monitor to troubleshoot any issues, spot trends, and configure operational performance. CloudWatch functions display alarms, graphs, custom metrics data and including statistics.

First login to your AWS server, and from...

In a previous article we learned about [Creating a PHP Daemon Service](https://beta.nomadphp.com/blog/50/creating-a-php-daemon-service). Now we are going to learn how to use methods to perform IPC - Inter-Process Communication - to communicate with daemon processes.
