[pmajali]

📝 Description

1. Adding Monitor in the regions endpoint. This specifies the monitor services enabled in a particular region.
2. Adding group_by and filters field to the dashboard widget

✔️ 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)

How do I run the relevant unit/integration tests?

unit-test: make test-unit TEST_SUITE=monitor
integration tests: make testint TEST_SUITE=monitor

The widgets property should be a list of DashboardWidget objects, but the current implementation will only handle a single widget. This should be Property(List[DashboardWidget]) to maintain the original list functionality.

[pmajali]

Since the codebase handles all lists in this way, its specified like this and client can handle widget as list.

Overall looks good, can you fix the build issue please?

I'm already using the default_factory for filters field in dashboard, I still see this in build logs.
ValueError: mutable default <class 'types.SimpleNamespace'> for field filters is not allowed: use default_factory

Can you suggest how can this be resolved?
