Network Analyzer uses Recommender commands. Recommender is a Google Cloud service that provides usage recommendations for Google Cloud products and services. For a complete list of Recommender insight types, see the Recommender insight types.
Request insights
gcloud
To list insights for a Google Cloud project, run the following command:
gcloud recommender insights list \
    --project=PROJECT_ID \
    --location=LOCATION \
    --insight-type=INSIGHT_TYPE \
    --filter=EXPRESSION \
    --limit=LIMIT \
    --page-size=PAGE_SIZE \
    --sort-by=SORT_BY \
    --format=json
Replace the following:
- PROJECT_ID: the project ID that you want to list insights for. You can also list all insights for a folder, organization, or a billing account.
- LOCATION: the location to list insights for, such as- global,- europe,- asia-east1, or- us-central1-a.
- INSIGHT_TYPE: the Network Analyzer insight type to request, such as- google.networkanalyzer.vpcnetwork.connectivityInsight.- For a complete list of insight types, see Insight groups and types. 
The following fields are optional:
- EXPRESSION: apply this Boolean filter to each resource that you want to list.- If the expression evaluates as - True, that item is listed. For more details and examples of filter expressions, run- $ gcloud topic filtersor see the- gcloud topic filtersdocumentation.
- LIMIT: the maximum number of resources to list; the default number of resources listed is unlimited.
- PAGE_SIZE: the maximum number of resources to list per page.- The default page size is determined by the service; otherwise, there is no paging. Paging might be applied before or after - FILTERand- LIMIT.
- SORT_BY: a list of comma-separated field key names to sort by for a resource.- The default order is ascending. To specify a descending order, prefix a field with - ~(a tilde).
API
To get insights for a Google Cloud project, make a GET request to the
projects.locations.insightTypes.insights method:
https://recommender.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/insightTypes/INSIGHT_TYPE/insights
Replace the following:
- PROJECT_ID: the project ID.
- LOCATION: the location to list insights for, such as- global,- europe,- asia-east1, or- us-central1-a.
- INSIGHT_TYPE: the Network Analyzer insight type to list, such as google.networkanalyzer.vpcnetwork.connectivityInsight.- For a complete list of insight types, see Insight groups and types. 
The following example shows a sample response for this command:

Describe insight details
gcloud
To list details of a particular insight, run the following command:
gcloud recommender insights describe INSIGHT_ID \
    --project=PROJECT_ID \
    --location=LOCATION \
    --insight-type=INSIGHT_TYPE
Replace the following:
- INSIGHT_ID: the ID of the insight to describe.
- PROJECT_ID: the ID of the project containing the insight.
- LOCATION: the location to list insights for.
- INSIGHT_TYPE: the Network Analyzer insight type of the insight, such as- google.networkanalyzer.vpcnetwork.connectivityInsight.- For a complete list of insight types, see Insight groups and types. 
API
To get details for an insight, make a GET request to the
projects.locations.insightTypes.insights method:
https://recommender.googleapis.com/v1/projects/PROJECT/locations/LOCATION/insightTypes/INSIGHT_TYPE/insights/INSIGHT_ID
Replace the following:
- PROJECT_ID: the project ID.
- LOCATION: the location of the insight.
- INSIGHT_TYPE: the Network Analyzer insight type of the insight, such as- google.networkanalyzer.vpcnetwork.connectivityInsight.- For a complete list of insight types, see Insight groups and types. 
- INSIGHT_ID: the insight ID for the insight.
