Memory allocation

Most Web Help Desk systems perform well with a 3.0 GHz processor and 4 GB of RAM. This configuration will support up to 20 techs. If you plan to support more than 20 techs, SolarWinds recommends adding 1 GB of additional RAM for every 10 additional techs.

If you plan to integrate Web Help Desk with SolarWinds Orion, ensure your Orion server is running SolarWinds Orion Core 2012.2 or higher. Web Help Desk requires this version of Orion Core so it can automatically integrate SolarWinds alerts. See the SolarWinds NPM documentation for upgrade and licensing instructions.

Deployments with fewer than 20 techs

If you plan to support 20 tech sessions or less in your deployment, you can run Web Help Desk on a system with:

  • A supported operating system
  • A 32-bit Java Virtual Machine (JVM)
  • 4 GB of RAM (up to 3.7 GB of RAM for the tech sessions, JVM support, operating system, and any additional services you need to run on the system)

This configuration supports 10 - 20 tech sessions with no on-board memory issues.

To adjust the maximum memory setting, edit the MAXIMUM_MEMORY option in the whd.config file. This file is located in the Web Help Desk home folder. The default home folder varies for each operating system, as listed below.

Operating system Path
macOS /Library/WebHelpDesk
Microsoft Windows Server \Program Files\WebHelpDesk
Linux /usr/local/webhelpdesk

Deployments with more than 20 techs

If you plan to support more than 20 tech sessions in your deployment, SolarWinds recommends installing Web Help Desk on a system running:

  • A supported operating system
  • A 64-bit JVM
  • 4 GB of RAM for 20 tech sessions plus 1GB of RAM for each additional 10 tech sessions

JVM memory allocation

Web Help Desk requires additional max heap memory over the Java Virtual Machine default setting. To improve application performance, increase the JVM memory and then restart Web Help Desk.
