✔️ How to Test

1. Testing the regions endpoint

import os
import logging
from linode_api4 import LinodeClient

client = LinodeClient(os.environ.get("MY_PERSONAL_ACCESS_TOKEN"))
client.base_url = "https://api.linode.com/v4beta"

regions=client.regions()
for reg in regions:
    print(f"Region: {reg.id}")
    print(f"  Monitors - Alerts: {reg.monitors.alerts}")
    print(f"  Monitors - Metrics: {reg.monitors.metrics}")
    print("---")

2. Test group_by and filter in dashboard widget

dashboard = client.monitor.dashboards(service_type="linode")
for d in dashboard:
    print("ID:", d.id)
    print("Service Type:", d.service_type)
    for widget in d.widgets:
        print("Label:", widget.label)
        print("Metric:", widget.metric)
        print("Unit:", widget.unit)
        print("group_by:", widget.group_by)
        if widget.filters:
            for f in widget.filters:
                print("label:", f.dimension_label)
                print("operator:", f.operator)
                print("values:", f.value)
