# Graphs⁣⁣⁣⁣

The Graphs tool allows to trace the device parameters represented in the diagrams. Available modes: realtime tracking, displaying data for hour, day, week or month. Choose mode in the drop-down list located in the lower right corner of the "Graphs" section. By default, the system displays the daily data log.

Scaling can be performed for all active diagrams using the timeline at the bottom of the page.

To display a diagram of the certain device parameter values, activate this parameter at the top of the page. There are two display modes available: a list, where all graphs are arranged sequentially one below the other, and tiles with two graphs in a row.

<table><thead><tr><th width="198">Parameter</th><th>Description</th></tr></thead><tbody><tr><td><strong>ARQ</strong></td><td>An indicator of the resent packets number.</td></tr><tr><td><strong>Capacity</strong></td><td>Available throughput of the wireless link, in Mbps.</td></tr><tr><td><strong>EVM</strong></td><td>Error vector magnitude - indicator of the measured input signal quality, telling how far are the received constellation symbols compared to the ideal symbols of the constellation. The parameter value must be as high as possible in absolute value. The recommended level should be less than -21 dB.</td></tr><tr><td><strong>Frame loss</strong></td><td>An indicator of the packets lost during transmission.</td></tr><tr><td><strong>Load</strong></td><td>Used throughput of the wireless link, in Mbps.</td></tr><tr><td><strong>MCS index</strong></td><td>Modulation and coding scheme selected for transmission.</td></tr><tr><td><strong>RSSI</strong></td><td><p>The RSSI indicator displays the received signal level for each channel (uplink and downlink). Available values:</p><ul><li><strong>-90...-80 dBm</strong> - close to the receiver sensitivity level, only the lowest modulations are available. </li><li><strong>-80...-60 dBm</strong> - average input range.</li><li><strong>-60...-40 dBm</strong> - the recommended range for achieving best performance.</li><li><strong>>-40 dBm</strong> - input signal level is too high.</li></ul></td></tr></tbody></table>

# Agent Instructions: 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 current page URL with the `ask` query parameter:

```
GET https://wiki.astrawireless.net/astra-wireless-documentation/technical-documentation/astra-quanta-technical-user-manual/operation-and-administration/graphs.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
