⭐ What are the key features of a System Monitoring Software?

Here are some important features of System Monitoring Software:

  • Monitoring multiple servers: Your system monitoring software should be able to handle servers from different vendors running various operating systems. It should also be able to monitor from various servers at multiple sites and in cloud environments.
  • Monitoring range of server metrics: It should offer various metrics like CPU usage, memory usage, disk space, upload/download rates, Monitoring CPU temperature, etc.
  • Monitoring applications: It should provide common monitoring applications using a deep knowledge that helps you to monitor key server processes, including web servers, database servers, and application stacks.
  • Automatic alerting: The most important and vital feature of any system monitoring tool is to provide automatic alerts when servers or network devices are down or overloaded.
  • Triggering actions in response to alerts: It should help to handle specific classes of network problems automatically.

  • Scalability: It should be able to grow with your business requirements, from a small or medium business (SMB) to a large enterprise.

⚡ What are the best practices for System monitoring?

When using network infrastructure monitoring tools, you need to keep in mind the following best practices. By implementing these, you can boost the success of your network infrastructure monitoring strategy.

  • Prioritize: Before establishing notification or threshold settings, you need to determine which components are most important.
  • Create alert resolution processes: You should always try to achieve the fastest and most efficient resolution for each type of alert you set up. This should be tied in with prioritization and should consider escalation.
  • Practice redundancy: If you have several data centers, make sure you are monitoring each of them from multiple locations.
  • Combine monitoring tools: You will get on-premises and cloud-based tools. Use both if it is necessary.
  • Keep tabs on the monitor: Never assume that just because you are not getting alert messages, nothing is wrong in your system. There could be an issue with the monitoring tool itself or in the system settings.
  • Review metrics on a regular basis: The thresholds you establish can be too high or too low. However, if you are receiving plenty of alerts or you aren’t notified when a problem in your system occurs, so you should change your threshold settings.
  • Conduct tests: You need to find out whether your alert system is effective when a critical issue arises. You need to do it only once when you implement a monitoring and alert system. It needs some fine-tuning. For that, you need to conduct regular tests so the robustness and effectiveness of the system remain efficient before a specific issue occurs.

❗ What is Result-based monitoring?

Result-based monitoring is the approach for tracking the results and performance of a system on a transparent basis. It helps you to measure the impact of evaluation.

💻 Where can I find device monitoring templates?

In case if your system monitoring software operates on a template model according to the device type and if you cannot find one, then you can ask the help desk of the software provider for device monitoring templates. You can also check forums for that tool.

🏅 When should you not use System Monitoring Software?

You should not use System Monitoring software when analyzing small and simple networks as these tools take lots of time to analyze I.T. infrastructure performance and generate the final report.

👉 What are the Network Monitoring Techniques?

Network monitoring uses a variety of techniques to test the availability and functionality of the network. Some more common techniques used to collect data for monitoring software are:

  • Ping: Ping monitoring tools send signals and record data, like the signal was received or not and how long it took the host to receive that signal.
  • SNMP: SNMP monitors individual devices in a network through monitoring software.
  • Syslog: Syslog is an automated messaging system that sends messages when a specific event affects a network device.
  • Scripts: In networks, scripts are used to substitute for any lack of functionality in network monitoring software.

🚀 What are the types of system monitoring software?

There are Seven types of system monitoring software:

  • Performance monitors: Processors of Simple Network Management Protocol (SNMP) status messages.
  • Performance testers: These type of software issue commands, such as ping and traceroute, to gather statistics.
  • Wireless sniffers: Are the packet sniffers or packet analyzers for wireless networks.
  • Firewalls: Read packets traveling through the network boundary.
  • Intrusion detection systems: Help you to identify standard and anomalous traffic patterns.
  • SIEM tools: This type of system monitoring tools examine log files for security breaches.

❓ How are system monitoring software deployed?

System monitoring tools can be deployed on-premises, on the cloud, or in a hybrid fashion. When comparing system monitoring tools, consider what type of deployment is ideal for your business.
