Integrate TiDB Cloud with Datadog

You can configure TiDB Cloud to send metric data about your TiDB clusters to Datadog. After that, you can view these metrics in your Datadog dashboards directly.

Prerequisites

To integrate TiDB Cloud with Datadog, you must have a Datadog account and a Datadog API key. Datadog grants you an API key when you first create a Datadog account.
If you do not have a Datadog account, sign up at https://app.datadoghq.com/signup.
To edit third-party integration settings of TiDB Cloud, you must have the Organization Owner access to your organization or Project Member access to the target project in TiDB Cloud.

Limitation

You cannot use the Datadog integration in Developer Tier clusters.

Steps

Step 1. Integrate with your Datadog API Key

On the TiDB Cloud console, choose a target project for Datadog integration, and then click the Project Settings tab.
In the left pane, click Integrations.
Click Integration to Datadog.
Enter your API key of Datadog and choose the site of Datadog.
Click Test Integration.
- If the test successes, the Confirm button is displayed.
- If the test fails, an error message is displayed. Follow the message for troubleshooting and retry the integration.
Click Confirm to complete the integration.

Step 2. Install TiDB Cloud Integration in Datadog

Log in to Datadog.
Go to the TiDB Cloud Integration page (https://app.datadoghq.com/account/settings#integrations/tidb-cloud) in Datadog.
In the Configuration tab, click Install Integration. The TiDBCloud Cluster Overview dashboard is displayed in your Dashboard List.

Pre-built dashboard

Click the Dashboard link in the Datadog card of the integrations. You can see the pre-built dashboard of your TiDB clusters.

Metrics available to Datadog

Datadog tracks the following metric data for your TiDB clusters.

Metric name	Metric type	Labels	Description
tidb_cloud.db_database_time	gauge	sql_type: Select\|Insert\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The total time consumed by all SQL statements running in TiDB per second, including the CPU time of all processes and the non-idle waiting time.
tidb_cloud.db_query_per_second	gauge	type: Select\|Insert\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of SQL statements executed per second on all TiDB instances, which is counted according to SELECT, INSERT, UPDATE, and other types of statements.
tidb_cloud.db_average_query_duration	gauge	sql_type: Select\|Insert\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The duration between the time that the client's network request is sent to TiDB and the time that the request is returned to the client after TiDB has executed it.
tidb_cloud.db_failed_queries	gauge	type: executor:xxxx\|parser:xxxx\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The statistics of error types (such as syntax errors and primary key conflicts) according to the SQL execution errors that occur per second on each TiDB instance.
tidb_cloud.db_total_connection	gauge	cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of current connections in your TiDB server.
tidb_cloud.db_active_connections	gauge	cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of active connections.
tidb_cloud.db_disconnections	gauge	result: ok\|error\|undetermined cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of disconnected clients.
tidb_cloud.db_command_per_second	gauge	type: Query\|StmtPrepare\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of commands processed by TiDB per second, which is classified according to the success or failure of command execution results.
tidb_cloud.db_queries_using_plan_cache_ops	gauge	cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The statistics of queries using Plan Cache per second. The execution plan cache only supports the prepared statement command.
tidb_cloud.db_transaction_per_second	gauge	txn_mode: pessimistic\|optimistic type: abort\|commit\|... cluster_name: `<cluster name>` instance: tidb-0\|tidb-1… component: `tidb`	The number of transactions executed per second.
tidb_cloud.node_storage_used_bytes	gauge	cluster_name: `<cluster name>` instance: tikv-0\|tikv-1…\|tiflash-0\|tiflash-1… component: tikv\|tiflash	The disk usage of TiKV/TiFlash nodes, in bytes.
tidb_cloud.node_storage_capacity_bytes	gauge	cluster_name: `<cluster name>` instance: tikv-0\|tikv-1…\|tiflash-0\|tiflash-1… component: tikv\|tiflash	The disk capacity of TiKV/TiFlash nodes, in bytes.
tidb_cloud.node_cpu_seconds_total	count	cluster_name: `<cluster name>` instance: tidb-0\|tidb-1…\|tikv-0…\|tiflash-0… component: tidb\|tikv\|tiflash	The CPU usage of TiDB/TiKV/TiFlash nodes.
tidb_cloud.node_cpu_capacity_cores	gauge	cluster_name: `<cluster name>` instance: tidb-0\|tidb-1…\|tikv-0…\|tiflash-0… component: tidb\|tikv\|tiflash	The limit on CPU cores of TiDB/TiKV/TiFlash nodes.
