# Updating RAS Performance Monitor

Newer versions of Grafana may be incompatible with a browser installed in the OS. A modern Edge browser is supported and will be embedded automatically in the RAS Console. But if it's not so, we suggest using a redistributable browser that comes in a form of a plugin. Plugins are available as separate msi packaged and distributed the same way as all other Parallels RAS distributions.

To avoid potential issues, Parallels RAS monitors which versions of Grafana and browser are installed and informs the RAS administrator about it when necessary. In a situation like that, when you select the **Monitoring** category, you will not see a dashboard as usual. Instead, a message is displayed that an updated browser plugin must be installed. To install the plugin, follow the instructions below.

1. In the main menu (at the top), click **Tools** and choose **Plugins**.
2. In the **Plugins** dialog, locate the **Browser Engine** plugin. The **State** column should indicate that it is not installed.
3. Select the plugin and click one of the following buttons:
   * **Install online** — Downloads the plugin from the Internet and installs it. Click this button if you can access the Internet from your environment.
   * **Install offline** — In an offline environment, admin can't get the list of plugins and instead uploads the plugin zip from a local file server. Only installed plugins are listed in the plugins table.
4. After the plugin is installed, you can go back to the Monitoring category and this time you will see the Grafana dashboard.

To update or remove a plugin (if necessary), use the same instructions as above, but select a plugin that is marked "installed" and then click **Update online** (or offline) or **Uninstall**. Please note that custom dashboards are now maintained after upgrades from Parallels RAS 18 to future versions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/ras-admin-guide/v20-en-us/parallels-ras-20-administrators-guide/performance-monitor/updating-ras-performance-monitor.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
