The source path in googleapis-gen for this library was changed from google-cloud-monitoring-nodejs to google-monitoring-nodejs. The old path no longer exists, causing OwlBot generation to fail. The configuration was updated to match:

• Source: /google/monitoring/google-monitoring-nodejs
• Destination: /owl-bot-staging/google-monitoring

Because the staging destination in .OwlBot.yaml was changed to /owl-bot-staging/google-monitoring (which does not match the actual package directory packages/google-cloud-monitoring), the OwlBot post-processor was unable to locate the existing package metadata (.repo-metadata.json) during template generation.

As a result, the template generator fell back to default settings:

1. Reverted the release level from stable to preview.
2. Changed the header to "Cloud Monitoring API: Nodejs Client" (default pretty name instead of "Stackdriver Monitoring").
3. Generated incorrect URLs pointing to packages/google-monitoring instead of packages/google-cloud-monitoring:

-[client-docs]: https://cloud.google.com/nodejs/docs/reference/monitoring/latest
-[product-docs]: https://cloud.google.com/monitoring/docs
+[homepage_samples]: https://github.com/googleapis/google-cloud-node/blob/main/packages/google-monitoring/samples
+[homepage_changelog]: https://github.com/googleapis/google-cloud-node/blob/main/packages/google-monitoring/CHANGELOG.md
+[homepage]: https://github.com/googleapis/google-cloud-node/blob/main/packages/google-monitoring

4. Reverted the copyright year in webpack.config.js to 2021:

-// Copyright 2026 Google LLC
+// Copyright 2021 Google LLC

Note: As noted by reviewers, fixing this internal misconfiguration is out of scope for this PR.

The TypeScript generator or prettier configuration resulted in minor formatting changes across all generated client and test files. Example of formatting changes:

-import type {Callback, CallOptions, Descriptors, ClientOptions, PaginationCallback, GaxCall} from 'google-gax';
+import type {
+  Callback,
+  CallOptions,
+  Descriptors,
+  ClientOptions,
+  PaginationCallback,
+  GaxCall,
+} from 'google-gax';

-  private _defaults: {[method: string]: gax.CallSettings};
+  private _defaults: { [method: string]: gax.CallSettings };
