Selenium Monitoring Setup
Last updated on 26 June, 2025You can monitor your websites by setting up Selenium on your LogicMonitor setup by installing a reachable Selenium Grid and configuring your Collector. This enables seamless integration of Selenium Webchecks and synthetic performance insights directly in your LogicMonitor portal.
Setting up Selenium monitoring involves the following:
- Installing the Selenium Grid
- Updating the LogicMonitor Collector for Synthetics

General Requirements for Setting up Selenium
To set up Selenium Synthetics with LogicMonitor, you need the following:
- Selenium Grid 4
For information, see Selenium Grid 4 from Selenium documentation. - LogicMonitor Collector 34.100 or later
Note: You must install the Collector in an environment with network access to the Selenium Grid. For more information, see Adding Collectors.
Note: Set the Shared memory (/dev/shm) value to a minimum 2GB to ensure the browser-based test runs successfully.
