If you are keeping your data in the cloud servers, you have probably asked yourself this question at least once: What is server monitoring? And why should you monitor servers? And finally, the last and the most important question: what should you look at when monitoring servers? We will go through all these questions one by one to help you understand the essentials of server monitoring.

What is server monitoring?

Server monitoring is a process of automatically scanning servers on the network for irregulations or failures. It enables you to identify issues and give solutions before they effect end-user productivity. Server monitoring allows companies to track server resources such as CPU usage, money consumption, Disk I/P, bandwidth, etc.

Companies will be able gain deeper insight into their systems and resource usage with an effective server monitoring. This will give businesses an ability to plan capacity and deliver high-quality end-user experience.

Why should you monitor servers?

Server monitoring provides several crucial answers in today’s changing and demanding environments. Here are the most outstanding benefits that server monitoring can give your company:

  • To find out if the issue affecting your app relates to network or server
  • To track server performance for immediate identification when the root causes any problem
  • To identify server hardware downtime
  • To know if your application is running smoothly on servers
  • To ensure server security, availability, and high-level performance

What to look at when monitoring servers?

Let’s take a closer look at what you should pay attention to when monitoring and tracking your servers.

RAM monitoring

A server can load information required by specific apps into RAM for faster access, thus refining the overall application performance. Memory monitoring will enable your IT staff to set RAM limitations in order to get alerted when RAM usage exceeds the pre-configured levels. In case RAM is consumed too fast, companies may stand in front of very serious problems such as the system not work effectively or - even worse - stop working at all.

CPU monitoring

CPU is the backbone of a computer. It is in charge of all the instructions of computer program for implementing the main arithmetical, logical and input/output operations by system. CPU monitoring enables IT staff to set limits to get alerts before the pre-defined limit is reached. There must always be some portion of CPU available to handle workload. This will give your IT team an ability to take actions for bringing CPU back or upgrading the CPU hardware to appropriate levels while at the same time delivering high-level customer experience. 

Bandwidth monitoring

Bandwidth monitoring enables companies to track their network interface and set limitations to get alerts when some metrics reach their maximum levels. These are the metrics that should be monitored:

  • Input and output traffic speed
  • Sent error packets number
  • Received error packets
  • Sent dropped packets number
  • Received Imp dropped packets

Disk space monitoring

Drive monitoring must be done continuously for ensuring its capacity and reliability, as server contains a lot of hardware components. It will allow your IT team to predict potential hardware failures. In case disk space is lower than acceptable levels, companies might see hardware failure, lost data, and downtime. Disk space monitoring enables IT staff to have insights into the consumption speed of server disks and keep appropriate capacity levels. They will be able to quickly identify and isolate the failing component.

Disk I/O monitoring

Disk I/O monitoring enables you to monitor Read and Write operations of logiccal disks on machines. It sets limits and sends notifications when any of the metrics listed below reach the maximum level:

  • Reads/sec – read operations rate on the disk
  • Writes/sec – write operations rate on the disk
  • Queue length – requests number on a disk when performance data is collected
  • Busy time –  passed time percentage when selected disk drive was serving read or write requests

We have understood the importance of server monitoring and what we should pay attention to. Though these are the most critical points there are a lot of other metrics yet to be tracked.
