# Query operator information

### Prerequisites

(<https://docs.tingchain.org/ting-application-chain-ecosystem/developers/working-with-node/query-operator-information#prerequisites>)

This guide assumes you have followed the Local Setup or guide on how to set up an IBFT cluster on the cloud.

A functioning node is required in order to query any kind of operator information.

With the Ting Application Chain, node operators are in control and informed about what the node they're operating is doing. At any time, they can use the node information layer, built on top of gRPC, and get meaningful information — no log sifting required.

{% hint style="info" %}
If your node isn't running on `127.0.0.1:8545` you should add the flag `--grpc-address <address:port>` to the commands listed in this document.
{% endhint %}

### Peer information

(<https://docs.tingchain.org/ting-application-chain-ecosystem/developers/working-with-node/query-operator-information#peer-information>)

**Peers list**

To get a complete list of connected peers (including the running node itself), run:

{% code title="List peers" %}

```bash
polygon-edge peers list
```

{% endcode %}

This returns a list of libp2p addresses that are currently peers of the running client.

**Peer status**

To get the status of a specific peer, run:

{% code title="Peer status" %}

```bash
polygon-edge peers status --peer-id <address>
```

{% endcode %}

Replace `<address>` with the libp2p address of the peer.

### IBFT info

(<https://docs.tingchain.org/ting-application-chain-ecosystem/developers/working-with-node/query-operator-information#ibft-info>)

Operators often need information about the operating node's state in IBFT consensus. The Ting Application Chain provides commands to query this information.

**Snapshots**

Return the most recent snapshot:

{% code title="Latest snapshot" %}

```bash
polygon-edge ibft snapshot
```

{% endcode %}

Query the snapshot at a specific height (block number):

{% code title="Snapshot at specific block" %}

```bash
polygon-edge ibft snapshot --num <block-number>
```

{% endcode %}

**Candidates**

Get the latest info on candidates (current proposed candidates and those not yet included):

{% code title="IBFT candidates" %}

```bash
polygon-edge ibft candidates
```

{% endcode %}

**Status**

Return the current validator key of the running IBFT client:

{% code title="IBFT status" %}

```bash
polygon-edge ibft status
```

{% endcode %}

### Transaction pool

(<https://docs.tingchain.org/ting-application-chain-ecosystem/developers/working-with-node/query-operator-information#transaction-pool>)

Find the current number of transactions in the transaction pool:

{% code title="Txpool status" %}

```bash
polygon-edge txpool status
```

{% endcode %}
