# pcp_node_info

## Name

pcp_node_info -- displays the information on the given node ID

## Synopsis

`pcp_node_info` [`option`...] [`node_id`]

## Description

`pcp_node_info` displays the information on the given node ID.

## Options

`-n `node_id``
`--node-id=`node_id``

  The index of backend node to get information of.

`Other options`

  See pcp_common_options.

## Example

Here is an example output:

    $ pcp_node_info -h localhost -U postgres 0
    host1 5432 1 1073741823.500000

The result is in the following order:

    1. hostname
    2. port number
    3. status
    4. load balance weight

Status is represented by a digit from [0 to 3].

- 0 - This state is only used during the initialization. PCP will never display it.

- 1 - Node is up. No connections yet.

- 2 - Node is up. Connections are pooled.

- 3 - Node is down.

The load balance weight is displayed in normalized format.

The `--verbose` option can help understand the output. For example:

    $ pcp_node_info --verbose -h localhost -U postgres 0
    Hostname: host1
    Port    : 5432
    Status  : 1
    Weight  : 0.5
