What is Server Monitoring? | 20 Best Server Monitoring tools In Use

What is Server Monitoring - Top 20 Server Monitoring tools

A server monitoring software enables you to stay on top of performance bugs and outages. You can have in-depth visibility into key performance metrics of your server infrastructure. In this blog, we’ll discuss the popular Server Monitoring tools that are being widely used.

What is Server Monitoring?

Server monitoring is the process of gaining clear insights into the physical or virtual activity on your servers. It monitors CPU Usage, Memory Consumption, I/O, Network, Disk Usage, Process etc.

Servers store and process information that is provided to other devices, users, or applications. Server Monitoring ensures the security of server data and helps in better performance of the server.

Why Server Monitoring?

Today, business computations and deployments are increasingly cloud-based. Cloud service providers like AWS and Azure provide IaaS Services on a pay-per-use basis. This enables the organizations to deploy more Servers into the cloud. Increased server count can be a growing security concern. Ensuring security along with maintaining performance and server availability is crucial for optimizing the customer experience.

  • Due to these concerns, organizations with cloud-deployed Servers need Server Monitoring Solutions.

Server Monitoring can have multiple objectives and may track different Key Performance Indicators (KPI). But the main objective of Server Monitoring is to protect the server from failures that may interrupt the server availability.

  • To detect, prevent and resolve any issues that can affect the server proactively.
  • It enables you to track data loss and server availability.
  • To know the capacity and speed of the server.
  • You can keep track of the responsiveness of the server.
  • It also tracks memory consumption, Input/Output, and CPU processes.
  • SM helps in identifying issues like app downtime and response time.

Server Monitoring Solution:

A server monitoring software helps you in the automation of the Server Monitoring process. Processes like identifying performance-related defects such as application downtime, response time, and resource utilization can be automated.

How does Server Monitoring Work?

The general process of Server Monitoring can be explained in 5 steps

1. Identify The Most Important KPIs

The process starts with the identification of the data you would like to track. The Key Performance Indicators can be different for different servers based on their functionalities for your organization. Critical KPIs for different servers are as follows

  • For application server – availability and responsiveness
  • For web server – capacity and speed
  • For a data storage server – data loss, latency, and data throughput.

2. Set Baseline KPI Values

In this step, all servers are measured against identified KPIs and an acceptable range of values for each KPI is measured. This initial measurement can be used as a baseline for future testing of the performance of the server.

3. Configure Data Collection And Analysis

A server monitoring tool must be properly configured to extract data from the server deployed in the cloud. These tools track the on-server activity by streaming event logs, Server OS KPIs including CPU, memory availability, disk performance, and network connectivity.

4. Set Up Comprehensive And Specific Alerts

After configuring your data collection, this step involves building an alerting system that alerts you in times of a KPI network breach or when your chosen metrics go below the baseline values.

5. Get Ready To Respond

In the final step, you will be needing an outline policy that guides your team about how to respond to the alerts. Which alerts should be the priority and how urgent a type of alert notification needs a response etc.
