# Configure flow logs

## [📄️Flow log data types](https://docs.tigera.io/calico-cloud/observability/elastic/flow/datatypes.md)

[Reference of key/value fields that Calico Cloud sends to Elasticsearch for flow logs, including endpoints, actions, byte counts, and policy verdicts.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/datatypes.md)

## [📄️Filter flow logs](https://docs.tigera.io/calico-cloud/observability/elastic/flow/filtering.md)

[Filter Calico Cloud flow logs through Fluentd to drop low-significance traffic and reduce managed Elasticsearch volume and cost.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/filtering.md)

## [📄️Configure flow log aggregation](https://docs.tigera.io/calico-cloud/observability/elastic/flow/aggregation.md)

[Tune Calico Cloud flow log aggregation levels to balance managed Elasticsearch volume and cost against pod and IP visibility for allowed and denied traffic.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/aggregation.md)

## [📄️Enable HostEndpoint reporting in flow logs](https://docs.tigera.io/calico-cloud/observability/elastic/flow/hep.md)

[Turn on host endpoint reporting in Calico Cloud flow logs to gain visibility into traffic at HostEndpoint interfaces on Kubernetes nodes.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/hep.md)

## [📄️Enabling TCP socket stats in flow logs](https://docs.tigera.io/calico-cloud/observability/elastic/flow/tcpstats.md)

[Add TCP socket statistics to Calico Cloud flow logs with eBPF programs that capture round-trip time, retransmits, and other per-socket metrics.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/tcpstats.md)

## [📄️Enable process-level information in flow logs](https://docs.tigera.io/calico-cloud/observability/elastic/flow/processpath.md)

[Add process executable paths and arguments to Calico Cloud flow logs with eBPF instrumentation for process-level visibility into network activity.](https://docs.tigera.io/calico-cloud/observability/elastic/flow/processpath.md)
