The Azure Monitor Activity Log is a platform log that provides insight into subscription-level events. The Activity Log includes information like when a resource is modified or a virtual machine is started. You can view the Activity Log in the Azure portal or retrieve entries with PowerShell and the Azure CLI. This article provides information on how to view the Activity Log and send it to different destinations.

## Ingestion volume rate limit reached
31
+
The [default ingestion volume rate limit](../service-limits.md#log-analytics-workspaces) for data sent from Azure resources using diagnostic settings is approximately 6 GB/min per workspace. This is an approximate value because the actual size can vary between data types, depending on the log length and its compression ratio. This limit doesn't apply to data that's sent from agents or the [Logs ingestion API](logs-ingestion-api-overview.md).

If your Log Analytics workspace is on the [legacy Free pricing tier](cost-logs.md#legacy-pricing-tiers) and has collected more than 500 MB of data in a day, data collection stops for the rest of the day. Wait until the following day for collection to automatically restart, or change to a paid pricing tier.

If you send data at a higher rate to a single workspace, some data is dropped, and an event is sent to the **Operation** table in your workspace every six hours while the threshold continues to be exceeded. If your ingestion volume continues to exceed the rate limit or you're expecting to reach it sometime soon, you can request an increase to your workspace by sending an email to [email protected] or by opening a support request.

## Azure Monitor Agent not sending data
48
+
49
+
[Azure Monitor Agent](../agents/azure-monitor-agent-overview.md) collects data from virtual machines and sends the data to Azure Monitor. An agent might stop sending data to your Log Analytics workspace in various scenarios. For example, when [Azure Site Recovery](/azure/site-recovery/site-recovery-overview) recovers a virtual machine in a disaster recovery scenario, the resource ID of the machine changes, requiring reinstallation of Azure Monitor Agent on the machine.
