Memory monitoring

Monitoring memory usage is essential in guaranteeing maximum performance. High rates of memory utilization results in decreased performance for the associated processes.

In addition, a steady increase in memory utilization over time may indicate a memory leak. A memory leak is when memory is allocated by processes as they start, but is not released when they end. Memory leaks degrade device performance over time. Typically, the device becomes unresponsive when memory is no longer available.

Memory monitoring keeps track of the free memory available. Memory use is tracked so that unexpected changes in usage can be detected, analyzed, and corrected.

Proactive memory monitoring using customizable reports provides in-depth insights into your memory usage. Accessing this information helps ensure memory utilization issues don't hinder your application availability or performance, and provides a more satisfactory end-user experience.

Memory utilization is the average utilization derived from the percent of available memory in use at a given moment.

Memory utilization monitoring: ManageEngine OpManager

OpManager monitors the memory utilization on Windows and Unix-based servers using SNMP, WMI, or CLI protocols.

OpManager's memory monitoring allows you to set memory thresholds so that you get alerted if your machine’s memory utilization reaches a critical level predetermined by you.

OpManger effectively ensures that:

  • Memory leaks are detected before performance is affected.
  • The minimum amount of physical memory required by the system remains available.
  • The total amount of physical memory allotted to the server is not exceeded.

OpManager monitors all the following metrics:

  • Free physical memory
  • Memory utilization
  • Page faults
  • Page reads
  • Page writes
  • Pages per second
  • Available page-file memory size
  • Available physical memory
  • Available virtual memory

With OpManager you can:

Start monitoring memory utilization instantly

  • Find memory utilization monitors associated for close to a dozen server types.
  • Spot high memory utilization at a glance using the intuitive dials in the snapshot page.
  • View the current memory utilization along with the total memory available.
  • Fine-tune the monitoring configurations right from the snapshot page, and narrow down a problem more quickly.

Stay ahead of the problem with threshold-based alerts

  • Specify thresholds, and get notified when memory usage hits the limit. This allows you to take the appropriate steps to avoid loss of data and downtime
  • Configure an increasing or decreasing threshold of available free memory.
  • Add more intelligence to threshold configurations by specifying the number of violations allowed before actually triggering an alert. You can implement bulk threshold configurations, too!
  • Avoid false alerts by specifying a rearm value to clear alerts.
