What are the Factors to consider in Server Monitoring Tools?

Server monitoring tools have risen in numbers on the market today. Selecting the best one for your need could be challenging for clients.

Below are the main factors to keep in mind when choosing the right tool solution:

  • Metrics Correlation: There must be a correlation between the monitoring tool and the matrix you are going for. This is important when debugging a problem.
  • Less Configuration Overhead: Consider getting a tool that needs minimal maintenance and is easy to set up. This is necessary, especially when running an enterprise monitoring platform. That chosen tool should meet your needs by just its default dashboard and alert settings.
  • Alerting features: Any monitoring tool should have the ability to notify you of any problem. This way, you can have oversight and deal with any resulting risk appropriately.
  • Coverage of Metric: The tool needs to collect and analyze all metrics you would consider essential. It should configure and customize the metrics to match your preference.
  • Anomaly Detection: You need to consider a monitoring solution with anomaly detection capabilities. This is because sometimes, you might not know that the monitoring system needs to give an alert when a problem arises.
  • Hardware considerations: Look into the hardware architecture used for your network monitoring. Some architecture contains particular components that need unique solutions.
  • Access Control: If you are looking for smooth and secure access, then the solution you select should be able to support SSO functionality identity management.
