These tools can help you monitor and analyze Eventarc\nactivity and growth, and understand the behavior, health, and performance of\nyour applications.\n\nBy default, Eventarc is configured to do the following:\n\n- Send data and system audit logs to Cloud Logging. You can use the collected logs to debug, troubleshoot, and gain insights about your applications.\n- Send system and resource metrics to Cloud Monitoring. You can use the collected metrics to monitor health and performance, identify trends and issues, and notify for changes in behavior.\n\nSend audit logs to Cloud Logging\n\nEventarc sends the following types of audit log data to\nCloud Logging:\n\n- [Admin Activity audit logs](/logging/docs/audit#admin-activity)\n- [Data Access audit logs](/logging/docs/audit#data-access)\n- [System Event audit logs](/logging/docs/audit#system-event)\n- [Policy Denied audit logs](/logging/docs/audit#policy_denied)\n\nData Access audit logs are\n[disabled by default](/logging/docs/audit/configure-data-access) because these\naudit logs can be quite large.\nFor more information, see [Eventarc audit logging](/eventarc/standard/docs/audit-logs) and [Eventarc publishing audit logging](/eventarc/standard/docs/audit-logs-publishing).\n\nQuery and view logs\n\nYou can use following tools to view and analyze your logs:\n\n- **Logs Explorer** is designed to help you troubleshoot and analyze the performance of your services and applications. To learn how to view logs in the Logs Explorer, follow the instructions in [View logs by using the Logs Explorer](/logging/docs/view/logs-explorer-interface).\n- **Log Analytics** is designed to run queries to analyze your logs, and then view or chart the results. To learn how to use Log Analytics, follow the instructions in [Query and analyze logs with Log Analytics](/logging/docs/analyze/query-and-view).\n\nYou can filter for Eventarc logs in the Logs Explorer by\nsearching for `eventarc` in the search field.\n\nFor more information about querying and analyzing logs, see\n[Query and view logs overview](/logging/docs/log-analytics).\n\nSend metrics to Cloud Monitoring\n\nEventarc sends metric data from monitored resources to\nGoogle Cloud Observability. A monitored resource in Monitoring represents a\nlogical or physical entity, such as a virtual machine, a database, or an\napplication. Monitored resources contain a unique set of metrics that can be\nexplored, reported through a dashboard, or used to create alerts. Each resource\nalso has a set of resource labels, which are key-value pairs that hold\nadditional information about the resource. Resource labels are available for all\nmetrics associated with the resource.\n\nEventarc sends metric data from the following monitored resource\nto Google Cloud Observability:\n\n- [`eventarc.googleapis.com/Location`](/monitoring/api/resources#tag_eventarc.googleapis.com/Location)\n\nResource metrics and labels\n\n\nThe \"metric type\" strings in this table must be prefixed\nwith `eventarc.googleapis.com/`. That prefix has been\nomitted from the entries in the table.\nWhen querying a label, use the `metric.labels.` prefix; for\nexample, `metric.labels.`\u003cvar translate=\"no\"\u003eLABEL\u003c/var\u003e`=\"`\u003cvar translate=\"no\"\u003eVALUE\u003c/var\u003e`\"`.\n\n| Metric type ^Launch stage^ *(Resource hierarchy levels)* Display name ||\n| Kind, Type, Unit Monitored resources | *Description* Labels |\n|-------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `quota/enrollments_per_message_bus/exceeded` ^BETA^ ***(project)*** Enrollments per message bus quota exceeded error ||\n| `DELTA`, `INT64`, `1` \u003cbr /\u003e **[eventarc.googleapis.com/Location](/monitoring/api/resources#tag_eventarc.googleapis.com/Location)** | *Number of attempts to exceed the limit on quota metric eventarc.googleapis.com/enrollments_per_message_bus.

There are several ways to\ncall the method, including using a language-specific client library, or by\ncreating a chart with\n[Metrics Explorer](/monitoring/charts/metrics-explorer). For an introduction to metrics\nand time series, see\n[Metrics, time series, and resources](/monitoring/api/v3/metrics). To learn how\nto read your metric data, see\n[Retrieve time-series data](/monitoring/custom-metrics/reading-metrics).\n\nUse Monitoring dashboards and alerts\n\nYou can use Monitoring dashboards and their associated charts to\nvisualize the data for Eventarc metrics.\n\nTo monitor these metrics in Monitoring, you can\n[create custom dashboards](/monitoring/charts/dashboards#custom_dashboards).\nYou can also [add alerts](/monitoring/alerts/using-alerting-api) based on\nthese metrics.\n\nWhat's next\n\n- [Eventarc audit logging](/eventarc/standard/docs/audit-logs)\n- [Troubleshoot issues](/eventarc/docs/troubleshooting)"]]
