; }; This Datadog integration is no longer receiving updates or new metric additions. You should instead use our [Datadog Agent Integration](/docs/vitess/tutorials/prometheus-metrics-datadog), which provides more metrics than this native integration. If you have any questions about migrating to the Datadog Agent Integration, [reach out to support](https://planetscale.com/contact?initial=support). ## Prerequisites * A [Datadog](https://www.datadoghq.com/) account ## Configuring the Datadog integration In Datadog, install the [PlanetScale integration](https://app.datadoghq.com/integrations/planetscale). Create a Datadog API key in your [Datadog Organization Settings](https://app.datadoghq.com/organization-settings/api-keys) and copy the key. In PlanetScale, go to your organization's [Integrations settings](https://app.planetscale.com/settings/integrations), and select **Configure** for the Datadog integration. Paste your Datadog API key into the field. Once complete, a "PlanetScale" dashboard will be available with incoming metrics from PlanetScale. PlanetScale Default Dashboard in Datadog ## Metrics We Collect Once configured, PlanetScale collects the following metrics from every branch in your organization. | **Metric name** | **Metric type** | **Description** | | :----------------------------------------- | :-------------- | :-------------------------------------------------------------------------------------------------- | | planetscale.connections | gauge | Number of active connections to a database branch. *Shown as connection.* | | planetscale.primary.cpu\_usage | gauge | Percentage of CPU utilized on a database branch's primary. *Shown as percent.* | | planetscale.primary.memory\_usage | gauge | Percentage of memory utilized on a database branch's primary. *Shown as percent.* | | planetscale.queries.latency | gauge | Query times in the p50, p95, p99 and p999 percentiles. *Shown as millisecond.* | | planetscale.replication\_lag | gauge | Replication lag in seconds between a database branch's primary and each replica. *Shown as second.* | | planetscale.rows\_read | count | Number of rows read from a database branch. *Shown as row.* | | planetscale.rows\_written | count | Number of rows written to a database branch. *Shown as row.* | | planetscale.tables.cumulative\_query\_time | count | Cumulative active query time in a database branch, by table and statement. *Shown as nanosecond.* | | planetscale.tables.queries | count | Number of queries issued to a database branch, by table and statement. *Shown as query.* | | planetscale.tables.rows\_deleted | count | Number of rows deleted from a database branch, by table. *Shown as row.* | | planetscale.tables.rows\_inserted | count | Number of rows inserted into a database branch, by table. *Shown as row.* | | planetscale.tables.rows\_selected | count | Number of rows selected in a database branch, by table. *Shown as row.* | | planetscale.tables.rows\_updated | count | Number of rows updated in a database branch, by table. *Shown as row.* | | planetscale.tables.storage | gauge | Total bytes stored in a database branch, by table. *Shown as byte.* | | planetscale.vtgate.errors | count | Number of errors encountered by a database branch's vtgate. *Shown as error.* | | planetscale.vttablet.mem\_util.max | gauge | Maximum memory utilization of a database branch's vttablet. *Shown as percent.* | | planetscale.vttablet.mem\_util.avg | gauge | Average memory utilization of a database branch's vttablet. *Shown as percent.* | | planetscale.vttablet.iops | gauge | Number of IOPS performed by a database branch's vttablet. *Shown as operation.* | ## Billing The Datadog integration is available on all of our [paid plans](https://planetscale.com/pricing). ## Frequently asked questions ### How do I track replication lag in Datadog? You can use the following formula to set alerts for replication lag: ```bash theme={null} (max:planetscale.replication_lag{ps_database: ps_tablet_type:replica, ps_branch:
}) ``` Make sure you replace `` with your PlanetScale database name and `
` with the name of the branch for which you'd like to track replication lag. ## Need help? Get help from [the PlanetScale Support team](https://planetscale.com/contact?initial=support), or join our [Discord community](https://pscale.link/community) to see how others are using PlanetScale.
