However, you can disable the logs if you want to reduce the\nlogging costs or don't have any specific requirement to log the health state\nchanges.\n\nFor logs of load balancer health checks, see [load balancer's health check logging](/load-balancing/docs/health-check-logging).\n\nBefore you begin\n----------------\n\n- Read the [Logs exclusion](/logging/docs/exclusions) documentation.\n- Review the [Cloud Logging pricing](/stackdriver/pricing).\n\nDisabling health state change logs\n----------------------------------\n\nTo disable the health state change logs, use the [Logs exclusions](/logging/docs/exclusions)\nto create an exclusion filter that discards the logs. \n\n### Console\n\n1. Go to the **Logs Router** page in the Google Cloud console.\n\n [Go to Logs Router](https://console.cloud.google.com/logs/router)\n2. In the `_Default` logging bucket row, click the\n *more_vert* menu\n and then select **Edit sink**.\n\n3. In the **Choose logs to filter out of sink** section, click **Add exclusion**.\n\n4. In the **Exclusion filter name** field, specify a name for your filter.\n\n5. Build the following exclusion filter:\n\n ```\n logName=\"projects/PROJECT_ID/logs/compute.googleapis.com%2Finstance_group_manager_events\" AND\n jsonPayload.instanceHealthStateChange:\"*\"\n ```\n6. To save the changes, click **Update sink**.\n\n After you save the changes, Compute Engine begins to filter out the instance\n health state change logs. To learn more, see [Managing sinks](/logging/docs/export/configure_export_v2#managing_sinks)\n and [Creating exclusion filters](/logging/docs/exclusions#create-filter-existing).\n\nEnabling health state change logs\n---------------------------------\n\nYou can enable any previously disabled instance health state change logs or\nremove the exclusion filter that you added earlier to\n[disable the logs](#disabling_health_state_change_logs). \n\n### Console\n\nTo enable health state change logging, do the following:\n\n1. Go to the **Logs Router** page in the Google Cloud console.\n\n [Go to Logs Router](https://console.cloud.google.com/logs/router)\n2. In the `_Default` logging bucket row, click the\n *more_vert* menu\n and then select **Edit sink**.\n\n3. In the **Choose logs to filter out of sink** section, click **Disable**\n next to the exclusion filter that filters out instance health state\n change logs. You can also **Delete** the exclusion filter if you no longer\n need it.\n\n | **Note:** Check all your exclusion filters because the same log entries could be targeted by more than one filter.\n4. Click **Update sink** to save the changes.\n\n After you save the changes, Compute Engine begins to log the health\n state changes.
