Webservers: Port 80 (HTTP Sensor), Ping
-You can use SNMP to get processor load, memory usage, network card usage, disk free, etc. I would specifically look at memory if you are hosting a shared server and also hard drive. Some monitoring programs allow you to monitor a specific folder. Those two sensors would be great for shared web server.
Mail: SMTP, POP, IMAP, Round Trip
We also monitor these services from various probes to detect potential issues from other areas around the world.
Would also be very wise to keep track of the hardware side of things. Voltage variations throughout the system can be catastrophic, RPM and Temperature drops can burn out equipment and help indicate if the system needs to get a good dusting or your datacenter forgot to fix the A/C.

Hello
One cause of excess I/O on a SQL Server is page splitting. Page splitting occurs when an index or data page becomes full, and then is split between the current page and a newly allocated page. While occasional page splitting is normal, excess page splitting can cause excessive disk I/O and contribute to slow performance.
If you want to find out if your SQL Server is experiencing a large number of page splits, monitor the SQL Server Access Methods object: Page Splits/sec. If you find out that the number of page splits is high, consider increasing the fill factor of your indexes. An increased fill factor helps to reduce page splits because there is more room in data pages before it fills up and a page split has to occur.
What is a high Page Splits/sec? There is no simple answer, as it somewhat depends on your system's I/O subsystem. But if you are having disk I/O performance problems on a regular basis, and this counter is over 100 on a regular basis, then you might want to experiment with increasing the fill factor to see if it helps or not.
There are various third party-tools that can be used to monitor each of these parameters of your web server on the real-time basis. These tools can be installed on the web server and may appear as additional components in the cPanel or Plex site administration dashboard of your web server.
I heard that WAPT is performance, a load, stress testing tool for web based applications. This is useful to monitor all the parameter that are used for server maintenance.
Apart from that if the basic services like httpd,crond,mysqld,DNS,named,exim are working fine. then you may have to run top command and just monitor it so that you will come to know all the processes which are responsible for the load in the server.

Our system included this package, and it's a full monitor setup that literally monitors everything you could possibly need to know about your system. I'd highly recommend looking into a third-party system that has live help and some sort of backups to keep a record of what's happening.
