Troubleshooting Tip: How to enable web service logs in FortiOS v7.4.10, v7.6.5, and v8.0.0

[jfelix09]

Description	This article describes identifying and mitigating web service issues (NodeJS).  This document outlines steps to enable additional logging and a temporary workaround.
Scope	FortiGate devices running FortiOS versions 7.4.10, 7.6.5, and 8.0.0.
Solution	Enable web-svc-perf Logging: Additional logs have been introduced in FortiOS versions 7.4.10, 7.6.5, and 8.0.0 related to the web service performance. Access the CLI and execute the following commands: config log settings set web-svc-perf enable end Restart the Node.js process to apply changes: diagnose nodejs process restart Collect and Share Logs: Download the web service (web-svc) logs (FortiGate GUI -> Log & Report -> System Events -> Web Service Events -> Select 'Download' button). Share these logs with Fortinet support to help identify the microservice causing the issue. Temporary workaround: If there is any issue related to the FortiGate web server services, a temporary workaround is available to periodically restart the Node.js process. This is not a preferred solution, but it can be used until the root cause is identified. Enable automatic restart of the Node.js process: config system global set web-svc-auto-restart enable end Note: This workaround should only be used as a temporary measure. It is crucial to collect and share logs to facilitate a permanent fix. Related documents: config log setting  diagnose web-svc
