20+ Top Server Management and Monitoring Tools

Server Monitoring is the process of monitoring a server's system resources like CPU Usage, Memory Consumption, I/O, Network, Disk Usage, Process etc.

Enterprises run multiple servers to deliver business critical services for their end users. Some of them include database servers, core app servers, caching servers, web servers, and more. Performance of each of these servers are critical because even if one of the servers fail, then it impacts the delivery of business critical services.

Therefore it is imperative to know any performance issues proactively so that they are identified at the early stage and fixed before they turn big and pose a threat to business. Server monitoring tools help in monitoring servers as well as the entire infrastructure. They also provide intensive reports on capacity planning to maintain the network without any hassle.

Server Monitor

Server Monitoring is the process of monitoring a server’s system resources like CPU Usage, Memory Consumption, I/O, Network, Disk Usage, Process etc. Server Monitoring also helps in capacity planning by understanding the server’s system resource usage.

A server monitor software helps in automating the process of server monitoring. Server performance monitoring also helps in identifying other performance related issues like resource utilization, app downtime and response time.

Why is it important to monitor server performance?

  • To monitor server availability and data loss.
  • To monitor the responsiveness of the server.
  • To know the server capacity, user load and speed of the server.
  • To detect and prevent any issues that might affect the server proactively.

collectd – The system statistics collection daemon

Collectd – gathers metrics from various sources, e.g. the operating system, applications, logfiles and external devices, and stores this information or makes it available over the network. Those statistics can be used to monitor systems, find performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you’re at the right place, too ;).
