모니터링을 하면 인스턴스가 원하는 대로 작동하는지 확인할 수 있습니다. 이 가이드에서는 Memcached 인스턴스 모니터링의 몇 가지 기본 예를 설명합니다. 여기에서 다루는 모니터링 유형 외에도 Memorystore for Memcached는 오픈소스 Memcached와 호환되므로 Compute Engine VM의 기존 Memcached 모니터링 도구를 사용하여 인스턴스를 모니터링할 수 있습니다.
Google Cloud 콘솔에서 인스턴스의 인스턴스 세부정보 페이지를 방문하여 여러 측정항목을 모니터링할 수 있습니다. 기본적으로 그래프에는 인스턴스의 현재 메모리 사용량과 최대 용량이 표시됩니다.Google Cloud 콘솔에서 사용할 수 있는 다른 측정항목으로는 활성 연결, 메모리 사용량, CPU 사용 시간, 적중률, 항목, 제거 수, 작업 수, 수신 바이트, 전송 바이트, 업타임, 사용되지 않은 메모리, 작업 가져오기, 작업 설정, 삭제 작업이 있습니다.
그래프에 표시된 측정항목을 변경하려면 왼쪽 상단의 드롭다운을 사용하세요. 기간을 변경하려면 그래프의 오른쪽 상단 모서리에서 다른 기간을 선택하세요.
Cloud Monitoring 사용
Cloud Monitoring은 Memcached 인스턴스의 업타임과 같은 측정항목을 볼 수 있는 모니터링 서비스입니다. Cloud Monitoring에서 사용할 수 있는 모든 Memorystore for Memcached 측정항목에 대한 자세한 내용은 Monitoring 참조 문서를 확인하세요.

This guide covers a few basic examples of monitoring Memcached\ninstances. In addition to the types of monitoring covered here,\nMemorystore for Memcached is compatible with open source Memcached, so you can use\nexisting Memcached monitoring tools from Compute Engine VMs to\nmonitor your instances.\n\nMonitoring instances in the Google Cloud console\n------------------------------------------------\n\nTo view an instance's core metrics:\n\n1. Go to the **Memorystore for Memcached** page in the Google Cloud console. \n [Memorystore for Memcached](https://console.cloud.google.com/memorystore/memcached/instances?)\n2. Click the Instance ID of the instance you'd like to view.\n\nYou can monitor several metrics by visiting an instance's **Instance details**\npage in the Google Cloud console. By default, the graph shows the instance's\ncurrent memory usage and its max capacity. Other metrics available in the\nGoogle Cloud console are: Active Connections, Memory Usage, CPU Usage Time,\nHit Ratio, Items, Eviction Count, Operation Count, Received Bytes, Sent Bytes,\nUptime, Unused Memory, Get Operations, Set Operations, and Delete Operations.\n\nTo change the metrics shown on the graph, use the dropdown in its upper left\ncorner. To change the time frame, select a different period of time\nin the upper right corner of the graph.\n\nUsing Cloud Monitoring\n----------------------\n\n[Cloud Monitoring](/monitoring/docs) is a monitoring service\nthat allows you to view metrics such as uptime for your Memcached instances. For\nmore details about all Memorystore for Memcached metrics available from\nCloud Monitoring, see the [Monitoring reference documentation](/monitoring/api/metrics_gcp_i_o#gcp-memcache).\n\n### Signing up for Cloud Monitoring\n\nTo access the monitoring console, click **Monitoring** in the\nGoogle Cloud console navigation pane:\n\n[Go to Google Cloud console](https://console.cloud.google.com/)\n\nFor pricing information, see\n[Cloud Monitoring pricing](/stackdriver/pricing).\n\n### Viewing instance uptime, restart, and failover information in Monitoring\n\nTo view instance uptime information, use Metrics Explorer:\n\n1. Go to the Google Cloud console, login and navigate to the project with your\n Memcached instances:\n\n [Go to Google Cloud console](https://console.cloud.google.com/)\n2. Select **Monitoring** from the left navigation menu.\n\n3. In **Monitoring** , if the navigation pane isn't expanded,\n click **Expand**\n *last_page*.\n This button is located on the lower left of the console.\n\n4. If **Metrics Explorer** is shown in the navigation pane, click\n **Metrics Explorer** . Otherwise, select **Resources** and then select\n **Metrics Explorer**.\n\n5. In the **Find resource type and metric** field, enter\n `memcache.googleapis.com/node/uptime`.\n\nYour graph looks something like this:\n\n- Each line indicates a single instance.\n- Up and to the right indicates Memcached is up.\n- A drop off indicates a restart.\n- Missing data indicates unavailability.\n- Below your graph, there's a color-coded key that indicates which line belongs to which instance. As you hover over the key, the corresponding line on the graph is highlighted.\n\nYou can change the time horizon in the upper-right hand corner as well as add\nfilters to tailor the information you're seeing to a particular region, project,\ninstance, or node.\n\n### Viewing operations per second\n\nTo view an instance's operations per second, use Metrics Explorer:\n\n1. Go to the Google Cloud console, login and navigate to the project with your\n Memcached instances:\n\n [Go to Google Cloud console](https://console.cloud.google.com/)\n2. Select **Monitoring** from the left navigation menu.\n\n3. In **Monitoring** , if the navigation pane isn't expanded,\n click **Expand**\n *last_page*.\n This button is located on the lower left of the console.\n\n4. If **Metrics Explorer** is shown in the navigation pane, click\n **Metrics Explorer** . Otherwise, select **Resources** and then select\n **Metrics Explorer**.\n\n5. Select **Memcached instance** as the resource type.\n\n6. Enter `memcache.googleapis.com/node/operation_count` in the **Find resource\n type and metric** field.\n\n7. Choose **Sum** from the aggregation drop-down menu.\n\nCreating a dashboard to monitor Memcached memory usage\n------------------------------------------------------\n\n1. In the Google Cloud console, select **Monitoring**, or use the\n following button:\n\n [Go to Monitoring](https://console.cloud.google.com/monitoring)\n2. Select **Dashboards \\\u003e Create Dashboard**.\n\n3. Provide a name for the dashboard, e.g. \"Memcached Dashboard\", and click **Confirm**.\n\n4. Click **Add Chart**.\n\n 1. Provide a chart title. For example, \"Memcached Memory Usage\".\n\n 2. In the search box labeled **Find resource type and metric**, search for\n \"Memorystore Memcached Node\", and select the metric.\n\n 1. Enter \"Cache memory\" as the metric type.\n 1. In the Filter box, add a filter for instance_id and select the instance you want to monitor.\n 2. If you want to monitor the usage of all the Memorystore instances in your project, use Group by and select instance_id.\n5. Click **Save**. You can access this dashboard from the dashboards tab in the\n Monitoring UI.\n\n### Setting a Monitoring alert for a metric\n\nThis section explains how to set an alert in Monitoring for an\nindividual metric.\n\nTo create an alert for a metric:\n\n1. In the Google Cloud console, select **Monitoring**, or use the\n following button:\n\n [Go to Monitoring](https://console.cloud.google.com/monitoring)\n2. Click **Alerting** from the left navigation menu.\n\n3. Click the **Create Policy** button.\n\n4. Enter a Policy name.\n\n5. Click **Add Condition**.\n\n 1. Provide a name for the condition, for example \"Memory Usage Alert\".\n 2. Under **Target** , select Memorystore Memcached Node instance resource type.\n 1. Select the desired metric. For example, select \"Memory Usage\".\n 3. Under **Configuration** , choose your desired condition.\n 1. For example, for Memory Usage you can choose **Any time the series violates**.\n 4. Select values for **Condition triggers if** , **Threshold** , and duration (labeled as **For** ).\n 1. For example, use the **Condition** , *is above* , and set **Threshold** to the equivalent, in bytes, of 80% of your instance size. Set **For** to 1 minute initially to understand the usage pattern.\n 5. Click **Add**.\n6. Set up a notification channel:\n\n 1. Click the **Add notification channel** button.\n - Option 1) Choose *Email* from the **Notification Channel Type** menu.\n - Enter the email address where you want your alerts sent.\n - Option 2) See [Creating channels](/monitoring/support/notification-options#creating_channels) for instructions on setting up other types of notification channels.\n7. Click the **Save** button.\n\nViewing Memcached logs\n----------------------\n\nMemcached produces logs that Cloud Logging captures.\n\n### Viewing audit logs\n\n1. Go to the **Logs Explorer** page in the Google Cloud console.\n\n [Logs Explorer](https://console.cloud.google.com/logs)\n2. To view the audit logs, select **Audited Resource \\\u003e memcached.googleapis.com** from the\n resources drop-down.\n\nWhat's next\n-----------\n\n- View available [Memcached metrics](/memorystore/docs/memcached/memcached-metrics).\n- View available [Memcached configurations](/memorystore/docs/memcached/memcached-configs)."]]
