Gerrit Monitor is a free Chrome extension developed by Sylvain Defresne. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. The purpose of this extension is to help users monitor multiple Gerrit instances for code reviews that require attention.

With Gerrit Monitor, users can configure the Gerrit instances they want to monitor directly from the extension's option pages. The extension will then request the necessary permissions to synchronize this list of instances if the user is logged into Chrome.

This extension identifies incoming code reviews that require attention if the user has not given at least a +1 to it or if the author has added a message more recently than the user. Outgoing code reviews are also flagged if they have unresolved comments, including the user's own comments. Additionally, outgoing code reviews that have not received any comments in the last 24 hours, excluding autogenerated comments, are considered stale.

Gerrit Monitor also provides several updates and bug fixes in its latest versions. Versionincludes a fix to ensure the extension works on Gerrit instances where the "star:" operator has been removed. Versionintroduces the option to disable "error" notifications, while versionfixes error reporting in the badge and popup. Versioncorrectly reports authentication errors and reduces the duration for which results are cached.
