# Domain expiration date

Plugin: go.d.plugin
Module: whoisquery

## Overview

This collector monitors the remaining time before the domain expires.




This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.


### Default Behavior

#### Auto-Detection

This integration doesn't support auto-detection.

#### Limits

The default configuration for this integration does not impose any limits on data collection.

#### Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.


## Metrics

Metrics grouped by *scope*.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.



### Per domain

These metrics refer to the configured source.

Labels:

| Label      | Description     |
|:-----------|:----------------|
| domain | Configured source |

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| whoisquery.time_until_expiration | expiry | seconds |



## Alerts


The following alerts are available:

| Alert name  | On metric | Description |
|:------------|:----------|:------------|
| [ whoisquery_days_until_expiration ](https://github.com/netdata/netdata/blob/master/src/health/health.d/whoisquery.conf) | whoisquery.time_until_expiration | time until the domain name registration expires |


## Setup

### Prerequisites

No action required.

### Configuration

#### File

The configuration file name for this integration is `go.d/whoisquery.conf`.


You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/whoisquery.conf
```
#### Options

The following options can be defined globally: update_every, autodetection_retry.


<details open><summary>Config options</summary>

| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| update_every | Data collection frequency. | 60 | no |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no |
| source | Domain address. |  | yes |
| days_until_expiration_warning | Number of days before the alarm status is warning. | 30 | no |
| days_until_expiration_critical | Number of days before the alarm status is critical. | 15 | no |
| timeout | The query timeout in seconds. | 5 | no |

#### Examples

##### Basic

Basic configuration example

```yaml
jobs:
  - name: my_site
    source: my_site.com

```

##### Multi-instance

> **Note**: When you define more than one job, their names must be unique.

Check the expiration status of the multiple domains.

## Troubleshooting

### Debug Mode

To troubleshoot issues with the `whoisquery` collector, run the `go.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.

- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.

  ```bash
  cd /usr/libexec/netdata/plugins.d/
  ```

- Switch to the `netdata` user.

  ```bash
  sudo -u netdata -s
  ```

- Run the `go.d.plugin` to debug the collector:

  ```bash
  ./go.d.plugin -d -m whoisquery
  ```
