This page contains information on monitoring system resources and performance.
For information on monitoring data content and activity see:
To check your site is accessible you can check that the login page of the web file manager is available and responsive.
To check also that server is operational over a network you can call an API to check, for example, that a folder exists. There is such a script available under Access Anywhere scripts for monitoring.
You can use any platform that supports monitoring of CentOS 7 including SNMP.
For example, with the Amazon Cloud you could use CloudWatch as noted in Getting Started with AWS Cloud - Systems Monitoring.
We recommend monitoring the following metrics.
vmstat Procs r: The number of processes waiting for run time. b: The number of processes in uninterruptible sleep. Memory swpd: the amount of virtual memory used. free: the amount of idle memory. active: the amount of active memory. Swap si: Amount of memory swapped in from disk (/s). so: Amount of memory swapped to disk (/s). IO bi: Blocks received from a block device (blocks/s). bo: Blocks sent to a block device (blocks/s). CPU us: Time spent running non-kernel code. (user time, including nice time) sy: Time spent running kernel code. (system time) id: Time spent idle. st: Time stolen from a virtual machine.%%''

If you are using MariaDB replication you could also use the database replication monitoring script. See Access Anywhere scripts for monitoring.
Monitor the network traffic using your monitoring system. Or you can get the information from
cat /proc/net/dev
