:Monitor a ClickHouse database

Last Updated:Dec 16, 2024

Managed Service for Prometheus actively pulls performance data from your ClickHouse database based on the specified parameters. This way, you can monitor the database in real time and flexibly analyze the monitoring data. This topic describes how to monitor a ClickHouse database.

Prerequisites

Container cluster

ECS instance

Procedure

  1. Log on to the Managed Service for Prometheus console. In the left-side navigation pane, click Integration Center.

  2. Click Clickhouse and set the parameters as prompted. The following tables describe the key parameters.

    Container cluster

    Parameter

    Description

    Clickhouse address

    The endpoint of the database. Example: http://clickhouse-simple-01.default:8123.

    Clickhouse username

    The username of the database.

    Clickhouse password

    The password of the database.

    Metrics collection interval (seconds)

    The interval for collecting monitoring data. The default value is 15.

    ECS(VPC)

    Configuration Item

    Description

    Clickhouse address

    Specify the Clickhouse Scrape address, for example: http://clickhouse-simple-01.default:8123.

    Clickhouse username

    The username of the database.

    Clickhouse password

    The password of the database.

    Metrics collection interval (seconds)

    The interval for collecting monitoring data. The default value is 15.

    Custom Labels

    Add tags to the metrics of the ECS instance. Then, you can monitor, manage, query, or analyze the metric data in a fine-grained manner when you use tools such as Grafana. For more information, see Add tags to the metrics of an ECS instance using a VPC.

    Note
    • A tag key cannot contain special characters used in the Prometheus functionality, such as hyphens (-), periods (.), or percent signs (%).

    • Tags must be specified in the key-value format required by Prometheus.

View and manage the monitoring data of the database

The installed component is displayed on the Integration Management page in the Managed Service for Prometheus console. The Integration Management page consists of the Integrated Environments, Integrated Addons, and Query Dashboards tabs, where you can view information such as targets, metrics, dashboards, and alerts.

Targets

In the Targets section of the Self-Monitoring tab, you can view the list of targets discovered by the default jobs.
