Upgrading ICAgent

Updated on 2023-11-29 GMT+08:00

To deliver a better collection experience, LTS regularly upgrades ICAgent. When LTS prompts you that a new ICAgent version is available, you can follow the directions here to obtain the latest version.

NOTE:

Linux hosts support ICAgent upgrade on the Host Management page of the LTS console.

Procedure

  1. Log in to the LTS console and choose Host Management in the navigation pane on the left.
  2. On the Host Management page, click the Hosts tab.
  3. Select Hosts. Select one or more hosts where ICAgent is to be upgraded, and click Upgrade ICAgent.

    Select CCE Cluster. In the drop-down list on the right, select the cluster whose ICAgent is to be upgraded, and click Upgrade ICAgent.

    NOTE:
    • You need to create a CCE cluster before you can collect container standards and send them to AOM.
    • To disable the function of exporting container standards to AOM, you need to have ICAgent 5.12.133 or later.
    • If you create a CCE cluster for the first time, ICAgents will be installed on hosts in the cluster by default, and logs will be reported to AOM. Output to AOM is enabled by default. To report logs to LTS, disable Output to AOM before upgrading ICAgents. You are advised to choose Log Ingestion > Cloud Service > Cloud Container Engine (CCE) to collect container data and output it to LTS instead of AOM.
    • CCE cluster ID (ClusterID): Each cluster has a fixed ID.
    • When ICAgent is upgraded, LTS creates log groups and host groups for your CCE cluster. The name of the log group and host group is k8s-log-{ClusterID}. You can create an ingestion configuration (Cloud Services > Cloud Container Engine (CCE)) to add logs of the current CCE cluster to the log group.
    • If the ICAgent is not installed on hosts in a cluster or the ICAgent version is too early, click Upgrade ICAgent to install the ICAgent on all hosts in the cluster.
  4. In the displayed dialog box, click OK.

    The upgrade begins. This process takes about a minute. When the ICAgent status changes from Upgrading to Running, the ICAgent upgrade has completed.

    NOTE:

    If the ICAgent is abnormal after the upgrade or if the upgrade fails, log in to the host and run the installation command. ICAgent can be re-installed on top of itself.
