Ways To Monitor The Linux Dedicated Servers

Virtual server is the server which doesnt 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 cant 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 servers. 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. Virtual Private Server Hosting.

Linux Disk Recovery After Disk Structure Corruption

blogger /

Linux is an open-source operating system that has various distributions, which include Fedora Core. It is an OS, which enables you to access latest open source applications. The OS uses a disk structure similar to various other Linux distributions and may face the same problem of corruption as others do. Corruption makes it inaccessible and unbootable, causing severe data loss. In such critical situations, you are required to opt for Linux data recovery solutions to get your valuable data back.

In a practical instance of the disk structure corruption in Fedora Linux OS, you may encounter the below error message when you reboot the Fedora operating system-based computer after it freezes at startup-

“EXT-fs: dm-0: couldn’t mount because of unsupported optional features (2000200) mount error 22 – mounting ext 3”

Subsequent to the above error message, you might get further error message that says-

“kernel panic – not syncing: Attempting to kill init.”

After this error message, Fedora operating system cannot detect and access Linux hard drive partitions when you try to perform data recovery Linux using Linux Rescue CD. When you try mounting the disk manually, it says that the disk has invalid arguments and thus it cannot be mounted.

Grounds of the problem As stated above, this problem occurs due to corruption to the logical structure of the Linux hard drive. It may also occur if disk data structures, like Superblock and file system, are damaged. Corruption might be the outcome of virus infection, improper system shutdown, operating system malfunction, and other similar reasons.

Resolution Use any of the below Linux recovery solutions to sort out this problem- Boot your Linux computer using the Rescue CD and then run pvscan command for checking the logical volumes. Run fsck -C -y /dev/hdXX command.

If none of the above Linux File Recovery methods work, you are required to format the disk and reinstall operating system.Although, formatting can fix all disk related problems, but it also cause serious data loss. In such situations, Linux disk Recovery software are required to retrieve lost data after formatting.
