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.

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.

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.

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

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.

jobs:
  - name: my_site1
    source: my_site1.com

  - name: my_site2
    source: my_site2.com

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	whoisquery.time_until_expiration	time until the domain name registration expires

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].
```
cd /usr/libexec/netdata/plugins.d/
```
Switch to the netdata user.
```
sudo -u netdata -s
```
Run the go.d.plugin to debug the collector:
```
./go.d.plugin -d -m whoisquery
```

Getting Logs

If you’re encountering problems with the whoisquery collector, follow these steps to retrieve logs and identify potential issues:

Run the command specific to your system (systemd, non-systemd, or Docker container).
Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.

System with systemd

Use the following command to view logs generated since the last Netdata service restart:

journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep whoisquery

System without systemd

Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector’s name:

grep whoisquery /var/log/netdata/collector.log

Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.

Docker Container

If your Netdata runs in a Docker container named “netdata” (replace if different), use this command:

docker logs netdata 2>&1 | grep whoisquery
