Overview

LTS uses ICAgent to collect logs from Cloud Container Engine (CCE) applications, self-built Kubernetes (K8s) applications, and ServiceStage containerized applications.

Figure 1 ICAgent workflow

1. Install ICAgent in a cluster. Choose an appropriate method based on your cluster type:
   • For a CCE cluster, ICAgent is installed on its hosts by default during cluster creation. If ICAgent is not installed, install it by referring to Installing ICAgent in Container Scenarios.
   • For a self-built Kubernetes cluster, see Ingesting Self-Built Kubernetes Application Logs to LTS.
   • To collect logs from containerized applications hosted on ServiceStage, install ICAgent in the clusters where these containerized applications are deployed. If ICAgent is not installed, install it by referring to Installing ICAgent in Container Scenarios.
2. Create a host group. Add the host with ICAgent installed to the host group. For details, see Managing Host Groups.
3. Ingest logs. LTS delivers collection configurations to ICAgent by host group, enabling ICAgent to report logs from multiple hosts to LTS based on these configurations.

   • Ingesting ServiceStage Containerized Application Logs to LTS
   • Ingesting Self-Built Kubernetes Application Logs to LTS
4. Configure indexing. After logs are ingested, configure full-text or field indexing on the index configuration page. This enables searching and analyzing the collected log data. For details, see Configuring Log Indexing.
