From version 7.1 onward, Lansweeper can scan performance information of Windows computers. Specifically, you can monitor the following resources and see them displayed in a Windows computer's Performance tab: CPU, RAM, disks and network traffic. By default, performance data is only scanned for your Lansweeper server itself. For other client machines, performance counter scanning must be manually enabled, instructions for which can be found in this article. Performance information is retrieved remotely through WMI (Windows Management Instrumentation), a management infrastructure built into Windows operating systems. No Lansweeper software is needed on the client machine whose data you want to scan.
To scan performance information of Windows computers, do the following:
- Make sure your Windows computers have been successfully scanned without an agent at least once. Instructions for setting up scanning of Windows computers can be found in this knowledge base article.
- Browse to the following section of the web console: Configuration\Server Options
- Lower the Delete performance counter data after XX days setting as much as possible, in the History Cleanup Options section of the page. Once you've configured performance scanning, this setting will determine how long the data is kept in the database. We recommend keeping the data only for as long as strictly required, to prevent unnecessary database growth.
- Browse to the following section of the web console: Scanning\Performance Scanning
- Hit the Add performance target button. By default, there will already be a target on the page to scan the performance information of your Lansweeper scanning server itself.
- Submit a name for the scanning target in the resulting popup.
- Choose whether you want to scan performance information of Windows computers in a specific group, in a specific report or in a specific selection of computers made by you. The group can be a static or dynamic group. We recommend enabling performance scanning only for the most critical machines in your network.
- Depending on which option you selected in the previous step, choose your asset group or report or make your asset selection using the Select Assets button.
- Submit your scan interval and hit Ok. The minimum interval is hard coded at 5 minutes. If you choose an interval below 5 minutes, it will automatically default to 5 minutes.
- Simply wait. An initial performance scan of the specified machines is immediately run and any subsequent scans are automatically executed based on the schedule you configured. If you have multiple scanning servers, a Windows computer's performance scan is executed by the last scanning server that performed a general scan of the machine. When a performance scan is taking place, you can see the Windows computer in your scanning queue under Scanning\Scanning Queue
- View scanned data in the Performance tab of your Windows computer webpages. To determine when a computer's performance information was last scanned, check the Last Performance Scan date in the machine's Scan Time tab.
Performance counter data includes processor, memory, hard drive and bandwidth usage. CPU and memory usage are scanned as percentages. Disk data includes (per disk and total) percentage of used disk space, disk reads per second, disk writes per second and disk transfers per second. Network interface data includes (per interface and in MB) network traffic received, network traffic sent and total network traffic.
The buttons at the top of each tab can be used to change the displayed time frame: 1 hour, 1 day, 1 week, 2 weeks or 1 month. Minimum, maximum and 95th percentile values are displayed for each resource as well. If you select a 1D or 1W view, an average value is calculated per hour and each hour is a data point. If you select a 2W or 1M view, an average value is calculated per day and each day is a data point. If a machine's performance data can temporarily not be scanned, because the machine is offline for instance, there will be a gap in the line graph for that time frame.
