Monitoring servers today – one of the major components of the system administrator or IT manager. And the bigger the company, the more customers it serves, the more numerous staff, the monitoring more critical servers in your organization. Although it should be noted that more and more servers are used and the number of computers with the company less than five or ten. Server equipment is designed to operate 24 hours 7 days a week, 365 days a year. Can not stop it, because it can disrupt the entire process, or result in data loss. But machines do not last forever, and they are failures. This implies the need for continuous monitoring of servers: the work of his services, applications, services, etc. What is monitored? First let's define the concept.
Monitoring – methods and system of observations on a particular object or process that provides an opportunity to observe their development and work, evaluate, quickly identify the effects of various external and internal factors. The monitoring results provide an opportunity to make adjustments to manage the object or process. What gives continuous monitoring of the servers? 1. System administrators will learn about the problem before it becomes available or as soon as it arises. In this case, the IT manager will not have to hear complaints from irate members of the inaccessibility required to operate the services can not contact the database, etc. Monitoring Server in this case reduces to a minimum reaction time sysadmin and system downtime, and therefore the company.
2. System administrator or head of IT department (if the company is large enough) can one look to assess the state of the IT structure as a whole or its individual parts in detail. 3. If your problem server monitoring helps to understand what caused the crash, and that – only its consequences. It also reduces the time resolve the problem to a minimum. In addition, the monitoring server can detect the current problems, and thus forestall or to prevent possible malfunction. Today the market of software you can find many solutions that make the process as automated server monitoring and less costly in financial point of view. The work program for monitoring network requires little or no interference of any kind of system administrator. Enough to configure certain checks, their frequency, methods of notification system administrator when certain failures or problems, or the program's response to specific monitoring results, such as: service restart, running external programs with parameters, etc. – And you can safely do other pressing matters. Server monitoring will be done 24 hours 7 days a week, the average person is, of course, will not be able to carry out. This means that the server and the system as a whole will be under constant and unremitting supervision and control. Server can be called a "brain" of the organization. They serve as a repository of critical information, ensure the "mental" work of the company, the relationship of different organs of the organization among themselves and unite them in a single organism. If the server stops functioning, the work of the organization can stand still. Server monitoring helps to avoid this problem, allowing to detect faults at an early stage and fix them in time, and can be prevented. A goal of the program for monitoring servers and networks in general – to make the process less expensive and more effective by a wide range of servers, and continuous inspections of its work.
