Fine-grained monitoring

Supported regions

For a list of regions where fine-grained monitoring is available, see the following tables.

Billing

After a CLB instance sends logs to Simple Log Service, Simple Log Service charges you for storage space, read traffic, requests, data transformation, and data shipping. For more information, see Simple Log Service Pricing.

Prerequisites

• You have activated Simple Log Service.

• You have configured a TCP listener or a UDP listener for the CLB instance. For more information, see Add a TCP listener or Add a UDP listener.

• You have created a Simple Log Service Project and a MetricStore in the region where the CLB instance is located. For more information, see Manage a Project and Create a MetricStore.

  Note

  A MetricStore and a Logstore in the same Project cannot have the same name.

Enable fine-grained monitoring

1. Log on to the CLB console.

2. In the top navigation bar, select the region where the CLB instance is located.

3. On the Instances page, click the ID of the target instance, and then click the Fine-grained Monitoring tab.

4. Enable fine-grained monitoring for the current region.

   If fine-grained monitoring is already enabled in the current region, skip this step.

   1. On the Fine-grained Monitoring tab, click Enable Fine-grained Monitoring.

   2. In the Enable Fine-grained Monitoring for SLB dialog box, select or enter a Project and a MetricStore, select I understand the above information., and then click OK.

      Important

      • This operation automatically creates a RAM role named AliyunServiceRoleForSlbLogDelivery. This role authorizes Server Load Balancer to push per-second monitoring metrics to Simple Log Service.

      • Do not revoke the authorization or delete the RAM role. Otherwise, Server Load Balancer cannot send per-second monitoring metrics to Simple Log Service.

5. Enable fine-grained monitoring for the target TCP listener or UDP listener.

   1. Open the Fine-grained Monitoring > Settings tab.

   2. On the Settings tab, turn on the Fine-grained Monitoring switch for the target TCP listener or UDP listener.

   Note

   After you enable the fine-grained monitoring feature, Simple Log Service receives monitoring data from CLB with a delay of about 5 seconds.

Next steps

After Simple Log Service collects per-second monitoring data from a CLB instance, you can query, analyze, download, ship, and process the data, or configure alerts in the Simple Log Service console. For more information, see Common operations for cloud product logs.

Metrics

The metrics in this topic use the time series data format. For more information, see Time series data (metric).

You can use PromQL or SQL statements to query and analyze data. For more information, see Introduction to time series data query and analysis.
