Memory Usage monitor

The Memory Usage monitor uses a local API call or SNMP communication to test the amount of physical memory (RAM) available on:

  • The local machine
  • A remote SNMP-enabled computer running a supported Microsoft Windows operating system
  • A remote SNMP-enabled computer running a Unix-based operating system such as Linux, Solaris, HP-UX, and so on
  • An SNMP-enabled device

The monitor 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.

Create a Memory Usage monitor

The Memory Usage Monitor Wizard helps you configure a Memory Usage monitor with the least amount of initial input. The wizard tests all the parameters you enter along the way to make sure the monitor operates as you expect in a production environment.

If you prefer greater control over the process, you can clone an existing Memory Usage monitor and make any required configuration changes.

  1. Click Devices in the toolbar.
  2. Locate and click the targeted device you want to monitor.
  3. In the toolbar, click Add > Add New Monitor.

  4. In the Select Monitor menu, click Memory Usage.
  5. Enter and select the wizard search criteria.

    1. Enter the IP address or domain name of the device, server, or sensor you want to monitor.
    2. Select the Use SNMP checkbox if the monitor will communicate with an SNMP-enabled network device.

      An SNMP Agent and the SNMP Service must be running on the monitored device for SNMP communications.

    3. Enter the UDP port number that the device responds on.
    4. Select the SNMP version used by the device. ipMonitor and the target device or server must use the same SNMP version.
    5. Select Use RPC/WMI checkbox to enable communications between ipMonitor and a targeted server (if required).

      An authenticated server connection requires a client access license (CAL).

    6. (Optional) Select a credential for monitoring. When selected, ipMonitor uses the credential account and password information to authenticate to the target machine and test the memory usage status.
  6. Click Next.
  7. Complete the wizard.

Test results

Test Result Description
Avail Indicates the amount of physical memory available on the system in megabytes (MB) and percentage (%).
avail-avg indicates the average amount of physical memory on the system based on the tests performed during the length of time specified in the Sample Size field.
