What Alibaba Cloud Simple Log Service is
Alibaba Cloud Simple Log Service collects, processes, stores, queries, analyzes, and monitors logs, metrics, and traces in real time. It is positioned for observability, DevOps, security auditing, business analytics, data pipelines, and log management, with cloud deployment and support for APIs and major desktop operating systems. Data can arrive through LoongCollector, WebTracking, SDKs, and APIs from applications, operating systems, databases, mobile devices, cloud services, and third parties. Real-time processing can structure, cleanse, filter, format, mask, encrypt, route, and enrich that data. Query options include index-based and scan-based searches, nearly 100 built-in functions, federated queries, and Dedicated SQL. Dashboards provide more than 10 chart types, and alerts can go to phone, SMS, DingTalk, WeChat, Lark, or webhooks. Integrations include Spark Streaming, Flume, and Flink for consumption, plus OSS, MaxCompute, TSDB, Grafana, and Quick BI. A free plan is available alongside usage-based billing. Listed rates include USD 0.061/GB for raw ingestion and USD 0.045/GB for read and write traffic; separate charges and usage limits apply.
