# Verify collector connectivity

You can verify the connectivity status of a collector instance on the Data Sources & Integrations page. Instances are grouped by integration, and the **Instances Status** column shows icons that summarize the instance statuses for the integration. Click the integration to see details for each individual instance.

<summary>Where can I see if I have a connectivity error on a collector instance?</summary>

On the Data Sources & Integrations page, instances in error status display an error icon. Hover over the error icon next to the instance name to see the error message as received from the API.

<summary>Where can I trace the connectivity changes of a collector instance?</summary>

Each status change of an instance is logged in the `collection_auditing` dataset. Querying this dataset can help you see all the connectivity changes of an instance over time, the escalation or recovery of the connectivity status, and the error, warning, and informational messages related to status changes.

This example searches for status changes on Strata IOT integrations:

```programlisting
dataset = collection_auditing 
|filter collector_type = "STRATA_IOT"
```

## 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, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/data-security-documentation/cortex-data-security-data-sources-and-connectors/administration-and-troubleshooting/verify-collector-connectivity.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
