Cloud Monitor:Use the dashboard feature of Hybrid Cloud Monitoring to monitor on-premises middleware instances

Step 1: Install an exporter for each on-premises middleware instance

The following example shows how to install an exporter on a Linux server where the Redis middleware is deployed.

1. Log on to the host where the middleware resides as the root user.

2. Run the following command to download the installation package of the exporter:

   wget https://cms-prometheus.oss-cn-hangzhou.aliyuncs.com//redis/redis_exporter_linux_amd64

3. Run the following command to grant the execution permissions on the redis_exporter_linux_amd64 file:

   chmod +x redis_exporter_linux_amd64

4. Run the following command to change the name of the redis_exporter_linux_amd64 file to redis_exporter:

   mv redis_exporter_linux_amd64 redis_exporter

5. Run the following command to install the exporter and start the service:

   ./redis_exporter -redis.addr localhost:6379 -web.listen-address localhost:9121

6. Run the following command to check whether the exporter is installed:

   ps -ef | grep "redis_exporter"

   If the following information is displayed, the exporter is installed.

   root      461050  460640  0 15:46 pts/0    00:00:00 ./redis_exporter -redis.addr localhost:6379 -web.listen-address localhost:9121root      461166  461128  0 15:47 pts/5    00:00:00 grep --color=auto redis_exporter

Step 2: Install the Cloud Monitor agent on a host

This section describes how to install the Cloud Monitor agent on a host that is accessible or inaccessible over the Internet. In this example, the host runs Linux.

Step 3: Create a metric import task for the data center

After you create a metric import task for the data center, the Cloud Monitor agent reports the metrics of hosts to the specified namespace and visualizes the related monitoring data in charts.

1. In the left-side navigation pane, choose Hybrid Cloud Monitoring > Namespace.

2. Find the namespace that you want to manage and click the icon for account quantity, cloud service quantity, metric quantity, or task quantity in the Metric Data column.

   Note

   Task quantity indicates the total number of tasks that are used to import metrics from self-managed data centers, AWS, Tencent Cloud, and Prometheus, on-premises log monitoring data, and Simple Log Service log monitoring data.

3. In the Metric management panel, click the Data Center tab. On the Data Center tab, click Metric Data.

4. In the Basic Task Information step of the Metric Data dialog box, configure the basic information of the metric import task and click Next.

   • Select Middleware to Be Monitored: Select Redis from the drop-down list.

   • Task Name: Enter the name of the metric import task.

   • Select Host: Select a host on which the Cloud Monitor agent installed.

5. In the Data Access Check step, confirm that the latest version of the Cloud Monitor agent is installed on the host and an exporter is installed on the middleware. Then, click Next.

6. In the Task Details step, specify the URL of the exporter and click Next.

7. In the Dashboard step, click Close.

Step 4: View the monitoring chart for on-premises data

You can view the monitoring chart for a specified metric of hosts.

1. On the Namespace page, find the namespace and click View Data in the Metric Data column.

2. On the View Data page, select a metric.

Step 5: Create custom charts for on-premises data

You can use the dashboard feature of Hybrid Cloud Monitoring to create a monitoring dashboard for the metrics of hosts and create custom charts.

1. In the left-side navigation pane, choose Hybrid Cloud Monitoring > Dashboards.

2. On the Dashboards page, click View Dashboard.

3. In the left-side navigation pane of the dashboard, click the icon. Then, click Add an empty panel.

4. On the Edit Panel page, configure metrics and monitoring charts.

   • On the Query tab, select the namespace and select metrics.

   • On the Panel tab, specify a panel title and enter a description. Then, configure visualization and other settings.

5. In the upper-right corner of the Edit Panel page, click Apply.

   The monitoring chart is created.

6. In the upper-right corner, click the icon. Then, specify the name of the dashboard and the directory in which the dashboard resides.

7. Click Save.

   The dashboard is created.

8. In the left-side navigation pane of the dashboard, choose > Manage. Then, click the dashboard name to view the dashboard.

Step 6: Configure an alert rule for on-premises data

You can configure alert rules for the metrics of hosts. If the specified conditions are met, you can receive alert notifications.

1. In the left-side navigation pane, choose Hybrid Cloud Monitoring > Namespace.

2. In the upper-left corner of the Namespace page, click Create Alert Rule.

3. In the Create Alert Rule panel, enter a name in the Rule Name field, select a namespace from the Namespace drop-down list, configure the Alert Expression (PromQL) parameter, and then select an alert contact group from the Alert Contact Group drop-down list.

4. Click OK.
