# CloudWatch Logs quotas
You can use the table in this section to review the default service quotas, also referred to as limits, for an Amazon account in Amazon CloudWatch Logs. Most of the service quotas, but not all, are listed under the Amazon CloudWatch Logs namespace in the Service Quotas console.
**Note**
If you want to request a quota increase for any of these quotas, see [the procedure](https://docs.amazonaws.cn/AmazonCloudWatch/latest/logs/cloudwatch_limits_cwl.html#service-quotas-manage) in this section.

## Managing your CloudWatch Logs service quotas
CloudWatch Logs has integrated with Service Quotas, an Amazon service that enables you to view and manage your quotas from a central location. For more information, see [What Is Service Quotas?](https://docs.amazonaws.cn/servicequotas/latest/userguide/intro.html) in the *Service Quotas User Guide*.
Service Quotas makes it easy to look up the value of your CloudWatch Logs service quotas.
------
#### [ Amazon Web Services Management Console ]
**To view CloudWatch Logs service quotas using the console**
1. Open the Service Quotas console at [https://console.amazonaws.cn/servicequotas/](https://console.amazonaws.cn/servicequotas/).
1. In the navigation pane, choose **Amazon services**.
1. From the **Amazon services** list, search for and select **Amazon CloudWatch Logs**.
In the **Service quotas** list, you can see the service quota name, applied value (if it is available), Amazon default quota, and whether the quota value is adjustable.
1. To view additional information about a service quota, such as the description, choose the quota name.
1. (Optional) To request a quota increase, select the quota that you want to increase, select **Request quota increase**, enter or select the required information, and select **Request**.
To work more with service quotas using the console see the [Service Quotas User Guide](https://docs.amazonaws.cn/servicequotas/latest/userguide/intro.html). To request a quota increase, see [Requesting a quota increase](https://docs.amazonaws.cn/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*.
------
#### [ Amazon CLI ]
**To view CloudWatch Logs service quotas using the Amazon CLI**
Run the following command to view the default CloudWatch Logs quotas.
```
aws service-quotas list-aws-default-service-quotas \
--query 'Quotas[*].{Adjustable:Adjustable,Name:QuotaName,Value:Value,Code:QuotaCode}' \
--service-code logs \
--output table
```
To work more with service quotas using the Amazon CLI, see the [Service Quotas Amazon CLI Command Reference](https://docs.amazonaws.cn/cli/latest/reference/service-quotas/index.html#cli-aws-service-quotas). To request a quota increase, see the [https://docs.amazonaws.cn/cli/latest/reference/service-quotas/request-service-quota-increase.html](https://docs.amazonaws.cn/cli/latest/reference/service-quotas/request-service-quota-increase.html) command in the [Amazon CLI Command Reference](https://docs.amazonaws.cn/cli/latest/reference/service-quotas/index.html#cli-aws-service-quotas).
