# Diagnostics using the Network UI

The **Human Network Interface** is a web-based utility that enables node operators to validate their node's network configuration and check their participation status in the consensus mechanism.

It offers a streamlined interface to interact with a set of RPC endpoints that help perform connectivity checks and fetch quorum-related data.

***

### Features

#### Network Connectivity Checks

* **`mishti_ping()`**\
  Check if your node's RPC interface is reachable.\
  \&#xNAN;*Requires your `rpc_url` as a parameter.*
* **`mishti_quic_ping(peer_id: string)`**\
  Verify if your node is reachable over the QUIC protocol.\
  \&#xNAN;*Requires your `peer_id` as a parameter.*

#### Quorum and Election Monitoring

* **`mishti_fetch_voting_power(peer_id: string)`**\
  Retrieve your node’s voting power in the current quorum.\
  \&#xNAN;*Requires your `peer_id` as a parameter.*
* **`mishti_fetch_election_info(peer_id: string)`**\
  Get details about the current election round and quorum state.\
  \&#xNAN;*Requires your `peer_id` as a parameter.*

### How to Run the Interface

You can run the Human Network UI locally using Docker:

```bash
docker run -p 3000:3000 -e NEXT_PUBLIC_RELAY_NODE_URL=http://44.217.242.218:8081/ mishtinetwork/network-ui:latest
```

> **Note**\
> Please contact the team to request access to the `mishtinetwork/network-ui:latest` Docker image.

Once the container is running, open <http://localhost:3000> in your browser to access the interface.

### RPC Reference

| Method                                | Description                           | Required Parameter |
| ------------------------------------- | ------------------------------------- | ------------------ |
| `mishti_ping()`                       | Pings the node via TPC.               | `rpc_url`          |
| `mishti_quic_ping(peer_id)`           | Pings the node over QUIC.             | `peer_id`          |
| `mishti_fetch_election_info(peer_id)` | Fetches current election information. | `peer_id`          |
| `mishti_fetch_voting_power(peer_id)`  | Fetches node’s voting power.          | `peer_id`          |

# 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.network.human.tech/for-operators/diagnostics-using-the-network-ui.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.
