# Prepare to initiate log push connection

**Connect from the log pusher to the vMontior Platform system.**

| **Source**    | **Destination**                                                                                                                                                                                            | **Port**  |
| ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| Log pusher IP | Subnet range: 116.118.93.130/28, i.e. 116.118.93.128 -> 116.118.93.143                                                                                                                                     | 10092 TCP |
| Log pusher IP | Domain: [hcm01-loghub01.vngcloud.vn ](http://hcm01-loghub01.vngcloud.vn/)[hcm02-loghub01.vngcloud.vn ](http://hcm02-loghub01.vngcloud.vn/)[hcm03-loghub01.vngcloud.vn](http://hcm03-loghub01.vngcloud.vn/) | 10092 TCP |

* The above connection needs to be open during the agent pushing logs

If the machines need to collect logs, some machines cannot open a direct connection. Refer to using the [collector](https://opentelemetry.io/docs/collector/) model to push through an intermediate host.

***

**Domain resolution**

Because the transmission channel data is **secured** by SSL encryption standard. If the log pusher is capable of querying public DNS, there is no problem. However, if not (which may occur in an on-premise environment), you need to add domain resolution according to the following table:

<table data-header-hidden><thead><tr><th></th></tr></thead><tbody><tr><td><pre><code># IP---------------| Domain
116.118.93.131      hcm01-loghub01.vngcloud.vn 
116.118.93.132      hcm02-loghub01.vngcloud.vn 
116.118.93.133      hcm03-loghub01.vngcloud.vn
116.118.93.134      hcm04-loghub01.vngcloud.vn
116.118.93.135      hcm05-loghub01.vngcloud.vn
116.118.93.136      hcm06-loghub01.vngcloud.vn
</code></pre></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://docs.vngcloud.vn/vng-cloud-document/vmonitor/dashboards/logs/lam-viec-voi-log-agent/chuan-bi-ket-noi-day-log.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.
