LoongCollector’s OneTime file collection feature enables fast, reliable migration of historical logs, data back‑filling, and batch processing by scanning files once, using checkpoints for fault tolerance, configurable execution windows, and rate‑limiting to avoid impacting live data streams.
LoongCollector, the open‑source cloud‑native collector behind Alibaba Cloud's Simple Log Service, achieves ten‑fold higher throughput, up to 80% lower CPU and memory usage, near‑linear scaling, zero‑copy processing, lock‑free event pools and adaptive concurrency, while guaranteeing enterprise‑grade reliability for petabyte‑scale log and metric ingestion.
This article explains how to protect sensitive user data in e‑commerce chatbot logs by routing all service logs through LoongCollector, pushing them to Alibaba Cloud SLS, and applying built‑in and keyword‑based mask functions so that privacy is preserved without breaking business logic.
This guide explains why modern enterprises need unified log collection for diverse security devices, introduces LoongCollector's flexible configuration for parsing and standardizing firewall logs from WAF, FortiGate, and Palo Alto, and provides step‑by‑step examples, code snippets, and visual results to enable efficient threat analysis and compliance.
This guide explains how to unify and parse heterogeneous firewall logs from vendors such as Longteng WAF, FortiGate, and Palo Alto by configuring LoongCollector, creating Alibaba Cloud Log Service resources, and applying JSON, key‑value, and CEF parsing rules to enable structured security analytics.
In a series of controlled benchmarks on an Alibaba Cloud ECS instance, the next‑generation LoongCollector log‑collection agent demonstrated dramatically higher throughput, lower CPU usage, and more efficient memory consumption than its predecessor iLogtail and popular open‑source alternatives such as FluentBit, Vector, and Filebeat across multiple log formats and traffic levels.
This article explains how enterprises can overcome the challenges of globally collecting logs by using Alibaba Cloud's high‑performance iLogtail/LoongCollector agents, selecting optimal network paths, applying cost‑saving strategies such as CloudLens diagnostics and LZ4 compression, and configuring multi‑region dual‑write for reliable, low‑cost log delivery.
This guide explains how enterprises can reliably and cost‑effectively gather logs from distributed overseas environments into Alibaba Cloud Log Service (SLS) by selecting the right network path, leveraging iLogtail/LoongCollector agents, applying compression, filtering, multi‑region routing, and using CloudLens for monitoring and cost control.
