log-agent
log-agent is an add-on based on Fluent Bit and OpenTelemetry for cloud native logging. It supports CRD-based log collection policies, as well as collects and forwards standard output logs, container file logs, node logs, and Kubernetes events of containers in a cluster.
The core components of log-agent include fluent-bit, cop-logs, log-operator, and otel-collector.
- fluent-bit: indicates the log collector, which is installed on each node as a DaemonSet.
- cop-logs: generates and updates configuration files on the collection side.
- log-operator: parses and updates log collection rules.
- otel-collector: forwards logs collected by fluent-bit to LTS in a centralized manner.
Resource Quota Requirements of Different Specifications
Ensure that the cluster has sufficient CPU and memory resources for scheduling when installing log-agent. Table 1 describes the resource quota requirements of different log-agent specifications.
