The name of the managed service created can be found in the output of the following command: \n\n```\ngcloud api-gateway apis describe API_ID\n```\n\nThe name of your service is the value of the `managedService` field.\n\nWhen users make requests to your API, API Gateway logs information about\nthe requests and responses. API Gateway also tracks three of the\n[four golden signals of monitoring](https://landing.google.com/sre/book/chapters/monitoring-distributed-systems.html#xref_monitoring_golden-signals):\nlatency, traffic, and errors. These usage and performance metrics help you monitor\nyour API.\n\nBefore you begin\n----------------\n\nTo generate logs and metrics for viewing, deploy an API and send requests to it. If you have not created and deployed an API to a gateway yet, try the\n[API Gateway quickstart](/api-gateway/docs/quickstart).\n\nAPI overview\n------------\n\nWhen you are debugging an issue with your service or just want to ensure that\neverything is running as expected, go to your API's overview:\n\n1. In the Google Cloud console, go to the **API Gateway** \\\u003e **APIs** page for\n your project:\n\n [Go to APIs](https://console.cloud.google.com/api-gateway/api)\n2. If you have more than one API, click the one you want to monitor.\n\n3. Ensure you are on the **Overview** tab.\n\n### Graphs\n\nThe overview page provides a number of graphs for some of the metrics, so you can spot any spikes, drops, or unexpected activity right away. Using the filters at the top of the page, you can:\n\n- Use the **Select graphs** drop-down list to show graphs for metrics you are interested in, and remove the ones you don't want to view.\n- Adjust the scope of the graphs by selecting from the various time spans. This adjusts the time range of values displayed, which also alters the point granularity.\n\n### Methods table\n\nWhen you are ready to drill down further, scroll below the graphs for a table\nwith metrics for individual methods in your API. You can:\n\n- In the top-left corner of the table, click the **Filter Table** icon to select refined filter query options from the drop-down table. Add an `OR` between each filter query to search for multiple terms.\n- In the top-right corner of the table, click the **Column Display Options** icon to display a drop-down list. Check the metrics you are interested in and clear the ones you don't want displayed.\n- In the top-right corner of the **Overview** page, select a time span for the metric values in the table by using the time span picker. This picks a time span for both the graphs and the table.\n\n### Logs\n\nWhen you spot an issue in the metrics, you can use the **Logs Explorer** page in the\nGoogle Cloud console to see logs of the requests and responses for your API.\n\n- To see logs for individual methods of your API, in the table click\n **View logs**.\n\n- To see logs for all methods in your API, in the bottom-right corner click\n [**View all logs**](https://console.cloud.google.com/logs/query).\n\n- To locate API Gateway logs directly from the Logs Explorer page:\n\n 1. In the Google Cloud console, go to the **Logs Explorer**\n page:\n\n [Go toLogs Explorer](https://console.cloud.google.com/logs/query)\n 2. Select **Produced API, \u003cvar translate=\"no\"\u003eSERVICE_NAME\u003c/var\u003e** , where\n \u003cvar translate=\"no\"\u003eSERVICE_NAME\u003c/var\u003e is the name of the\n managed service.\n\nSee the\n[API Gateway logs reference](/api-gateway/docs/audit-logging)\nfor details on the structure of the logs in the Logs Explorer.\n\nLearn what else you can do with the logs:\n\n- Get started using the\n [Logs Explorer](/logging/docs/view/logs-explorer-interface).\n\n Use the query pane to specify the set of log entries that you want to view,\n such as getting all requests with a latency greater than 300 milliseconds.\n- [Configure and manage sinks](/logging/docs/export/configure_export_v2).\n This lets you stream logs to BigQuery for further analysis, save the\n raw logs to Cloud Storage, or send them to Pub/Sub messaging\n topics.\n\n### Filter for a specific consumer project\n\nTo filter metrics for a specific consumer project:\n\n1. Get the\n [project number](/resource-manager/docs/creating-managing-projects#identifying_projects)\n of the API consumer's project. If you don't have permission to access the\n API consumer's project, ask someone who has permission to get the project\n number for you.\n\n2. In the Google Cloud console, go to the **API Gateway** \\\u003e **APIs** page\n for your project.\n\n [Go to APIs](https://console.cloud.google.com/api-gateway/api)\n3. In the top-left corner of the **Overview** page, enter the project number in\n the **Filter by Project Number** field.\n\n4. Click **Filter**.\n\nThe metrics on the page update to reflect traffic only from the specified\nproject.\n\nWhat's next\n-----------\n\n- [Tracing your API](/api-gateway/docs/tracing)"]]
