Virtual server is the server which doesn’t exist by physical manner. Still it will do all the functions of the real server. The virtual server hosting virtual servers to provide most efficient load balancing by acting like a single IP address for several clients and uses address translation to send the tasks to the real server to handle. Hereafter we will see how we are going to monitor private services and attributes of Linux dedicated servers.
The main attributes and services need to be monitor is CPU load, memory usage, disk usage, logged in users and running processes in the Linux Dedicated Servers. There are available some public services by the Linux dedicated servers they are the HTTP, FTP, SSH etc.
The following ways to monitor the Linux dedicated servers is based on out installation of nagios in our system as a monitoring tool. There are available a lot of ways to monitor the attributes and remote located servers of Linux/ UNIX. One of the main way is by using the SSH key and by the check_by_ssh plug-in to execute on the remote servers. This will be of very useful when we are monitoring hundred of thousands of system which is having a very high load.
Another important method of the Linux and UNIX remote servers using NRPE add-on. NRPE allow executing the remote plug-in on remote Linux and UNIX servers. This method is useful to manage internal resources like disk usage, memory usage etc on the remote host in the Linux dedicated servers.
The top ten Linux hosting websites are justhost.com, ipage, myhosting.com, immotion, dream host.com hub, arvixe, host cator, cirtex hosting, go daddy.com. Every provider is having advantages and disadvantages; they allow the companies to host their website using Linux operating system. When it comes to budget based servers. Because small start up companies can’t afford to the windows based servers since we have to pay for all the software packages are of only by cost.
All the Linux software packages are free of cost and hence to make a linx operating server is simple when compared to the windows operating system.
The third party tools play an important role in monitoring and maintaining the dedicated server. The important function of these monitoring tools is to check the safe level of certain parameters. CPU utilization, server RAM, physical temperature of the server is its various components, bandwidth usage and disk space usage. Here are the various third party tools to do this task. These tools can be installed on the web server and may appear as additional components in the c Panel or Plex site administration dashboard of your web server. The graphical design of the website traffic can be seen through the software package called as webalizer. As an IT manager you should know exact state of your server if incase it is a dedicated servers.
