Cloud Native Log Collection

Add-on Overview

The Cloud Native Logging add-on (log-agent) is developed based on Fluent Bit and OpenTelemetry for collecting logs and Kubernetes events. This add-on supports CRD-based log collection policies. It collects and forwards standard output logs, container file logs, node logs, and Kubernetes event logs in a cluster based on configured policies. It also reports Kubernetes events to AOM for configuring event alarms. By default, all abnormal events and some normal events are reported.

Add-on Parameters

Table 1 Parameters
Parameter	Mandatory	Type	Description
basic	No	object	Basic configuration parameters, which do not need to be specified
flavor	Yes	Table 2 object	Flavor parameters
custom	Yes	Table 3 object	Custom parameters

Table 2 Configuration of flavor
Parameter	Mandatory	Type	Description
description	No	String	Add-on description
name	Yes	String	Add-on specification name. The value is fixed at Single-instance.
replicas	Yes	String	Number of otel-collector component instances. The default value is 1.
resources	Yes	resources object	Container resource (CPU and memory) quotas

Table 3 Configuration of custom
Parameter	Mandatory	Type	Description
caCert	Yes	String	Specifies a client certificate, which is encrypted using Base64. This parameter is optional during installation. It is generated by the CCE add-on center and used for two-way authentication between components and webhook requests. Domain name to be issued: *.monitoring.svc.
serverCert	Yes	String	Specifies a server certificate, which is encrypted using Base64. This parameter is optional during installation. It is generated by CCE add-ons and used for two-way authentication between components and webhook requests. Domain name to be issued: *.monitoring.svc.
serverKey	Yes	String	Specifies the private key of a server, which is encrypted using Base64. This parameter is optional during installation. It is generated by CCE add-ons and used for two-way authentication between components and webhook requests. Domain name to be issued: *.monitoring.svc.
accessKey	No	String	Specifies the access key ID of a user, which is used to request AOM and LTS APIs. If this parameter is left blank, a temporary AK/SK is used.
secretKey	No	String	Specifies the access key of a user, which is used to request AOM and LTS APIs. If this parameter is left blank, a temporary AK/SK is used.
createDefaultStdout	No	Bool	Specifies whether to create the default policy for collecting container standard output logs and reporting them to LTS. This parameter is valid only after it is specified during the add-on installation. The default value is false.
createDefaultEvent	No	Bool	Specifies whether to create the default policy for collecting Kubernetes events and reporting them to LTS. This parameter is valid only after it is specified during the add-on installation. The default value is false.
multiAZEnabled	No	Bool	Specifies whether to deploy the add-on pods in multiple AZs. The default value is false. If this parameter is set to true, cross-AZ deployment is forcibly performed. If this parameter is set to false, cross-AZ deployment is preferred.
cluster_category	No	String	The value is fixed at CCE.
ltsAccessEndpoint	No	String	Specifies the address for reporting logs to LTS. If this parameter is left blank, the address specified in basic is used.
ltsEndpoint	No	String	Specifies the address of the LTS APIs. If this parameter is left blank, the address specified in basic is used.
aomEndpoint	No	String	Specifies the address for reporting events to AOM. If this parameter is left blank, the address specified in basic is used.
projectID	Yes	String	Specifies the ID of the project to which the current CCE cluster belongs. This parameter is optional during installation.
clusterID	Yes	String	Specifies the ID of the current CCE cluster. This parameter is optional during installation.
clusterName	Yes	String	Specifies the name of the current CCE cluster.

Table 4 Data structure of the resources field
Parameter	Mandatory	Type	Description
limitsCpu	Yes	String	CPU size limit (unit: m)
limitsMem	Yes	String	Memory size limit (unit: Mi)
name	Yes	String	Component name. Options: fluent-bit: component for collecting node logs cop-logs: generates soft links for collected files on each node. log-operator: generates fluent-bit and otel-collector configurations. otel-collector: reports collected logs and events to AOM and LTS.
requestsCpu	Yes	String	Requested CPU size (unit: m)
requestsMem	Yes	String	Requested memory size (unit: Mi)
