## What it is
LoongCollector (formerly iLogtail) is a high-performance, lightweight observability data collection agent from Alibaba for cloud-native environments. It collects logs, Prometheus metrics, and eBPF-based network/security telemetry and ships them to backends like Alibaba Cloud SLS or OpenTelemetry-compatible systems.

## Use cases
- collect logs from kubernetes clusters
- ship container logs to alibaba cloud sls
- collect prometheus metrics from nodes
- ebpf network observability monitoring
- lightweight agent for observability data collection
- replace filebeat or fluentd for log shipping
- collect security and network telemetry with ebpf

## When to choose
- you need very high-throughput log collection with low resource usage
- you run kubernetes or cloud-native workloads and need a unified agent for logs, metrics, and eBPF telemetry
- you send data to Alibaba Cloud SLS or OpenTelemetry backends

## When to avoid
- you need a fully vendor-neutral OpenTelemetry Collector-native pipeline with OTel ecosystem plugins
- you require first-class Windows desktop support or non-Linux edge deployments
- you want a mature large community beyond Alibaba's ecosystem
