What does the default maximum content length for HEC in Splunk Cloud typically set to?

The default maximum content length for the HTTP Event Collector (HEC) in Splunk Cloud is typically set to 1MB. This limit helps ensure that individual events or batches of events sent to Splunk Cloud do not exceed a size that could negatively impact performance or processing efficiency.

Setting the limit to 1MB strikes a balance between allowing significant amounts of data to be ingested while still maintaining system stability and performance. This size restriction also helps in efficiently handling network bandwidth, ensuring that the data transfer remains within practical limits.

While some configurations may allow for adjustments to this maximum size, especially in on-premises deployments, the default setting for Splunk Cloud is designed to provide an optimal experience with the resources available. More extensive data can be sent through multiple requests if needed, aligning with best practices for managing API calls and data ingestion in cloud environments.
