One of the most important factors that you should be constantly monitoring with your VPS or dedicated server, especially if you host clients on it, is the uptime of it; this means that you should always be using some type of monitoring service to ensure that your VPS or dedicated server, and if it isn’t you need to ensure that you are notified of the down time ASAP so that you are able to sort the problem out yourself, or notify the support team of your web host to ensure that the down time caused is minimal and that your server will come back online ASAP.

If you are a web host which is providing a responsible and sensible service, then in your terms and conditions you will probably have conditions set out regarding up uptime, which in most cases states things such as if a customer’s service is down for over a certain amount of time, or if the monthly uptime record doesn’t meet the one which is guaranteed then customers are able to request a refund; this in itself should provide you with the motivation to fix a server problem if you have set such rules out in your terms and conditions, since most companies wouldn’t want a servers worth of customers requesting refunds since they don’t think they have been provided with the amount of uptime which has been guaranteed. Most web hosts use their own internal monitoring system for their servers, since in most cases it will alert them quicker to a problem than an external solution would since an internal system is most likely monitored more closely, but with an external solution in place as backup in case the internal one fails. One thing to consider is that most external monitoring services monitor your website or server from multiple geographically different locations which means that they are able to provide a more reliable source of information when it comes to checking to see whether your VPS or dedicated server is online or not when compared to a monitoring system which is monitoring your VPS or dedicated server from one location or from one country or data center, which means that the produced results might not always be accurate and reliable.

When considering uptime solutions for your VPS or dedicated server, you should always take into consideration the effect that a program might have on the performance of your VPS or dedicated server; for example if you use an internal solution then you might need to install an ‘agent’ program which posts data about your server back to the master monitoring node, since information such as the speed that your server’s CPU is running at and the amount of memory that your server has left are factors that can only be gained by internal access to your server unlike other factors such as whether certain services are running or not that can be found out easily via pinging the port which the service runs on. You want to try and maximize the uptime of your VPS or dedicated server, which means that you should optimize the programs that you have installed on it, so that they don’t use up too many resources since the most common reason for a server crashing is that there aren’t enough resources available to keep the operating system going, which means that it just crashes because it is unable to run for any longer on the scarce resources that are available for it.

Conclusion

In conclusion, with the use of either internal or external monitoring systems, you are able to maximize the uptime of your VPS Hosting or dedicated server, thus ensuring that your customers, if you host them on your server, are happy with the service and level of uptime that you have been able to provide them with; you are also ensuring if you use your server for other purposes such as for receiving emails or for a website that emails are received as often as possible, and that visitors will still return to your website thus increasing your amount of revenue that you earn from adverts if applicable. You can also optimize your VPS or dedicated server as well as the programs that it runs to ensure that the amount of resources used is far lower, thus ensuring that you can install some more applications on your VPS or dedicated server or leave it as it is so that it is able to run fast; if running cPanel, then you can use the new optimized version since this will run much fast on a lower specification machine since it has been designed to take up less memory and utilize less CPU.

If you choose to use an internal monitoring system then you gain the ability to monitor internal factors of your server, such as the amount of CPU and memory that is available for use by the operating system and programs that you have installed on your VPS or dedicated server – this is very important if you are running a server which is hosting web hosting and design clients, since you don’t want their websites going down because of a lack of resources. Other factors which you might want to consider when choosing a monitoring system is the accuracy of the results that are collected and in turn produced; for example, with an external monitoring system you will want to be considering how spread the multiple geographical monitoring stations are and with the case of an internal monitoring system, you should find out whether internal server resources can be monitored or not – this will give you an advantage since you will be able to monitor all aspects of your server then, both internal and external which means that accurate results should be produced.
