Release v6.1.0

Whats new:

• With this release, argus provides ability to enable optimised resource tree structure using enableNewResourceTree: true parameter in argus-configuration.yaml file.

Fixes: 

• Added support for Kubernetes version 1.22
• Improved handling for deleted resources when deleteDevices parameter is set as true.

High level design details for Optimised Resource Tree

• Till Argus v5, there were dynamic groups created for each type of resource. This leads to increase in resource tree hierarchy which in turn impacts the performance on Argus.
• With this release, customer can opt for optimised resource tree option using enableNewResourceTree: true parameter in argus-configuration.yaml file.
• In optimised resource tree all namespace scoped resources like pods, deployments, services etc are grouped into "Namespaces" group separated as per individual namespaces further and non-namespace scoped resources are group into "ClusterScoped" group.

Note: During argus upgrade if Optimised resourceTree option is enabled for existing clusters, old resource tree will also be retained and User has to cleanup those groups manually.

Upgrade Steps

• While upgrading Argus chart you need to supply the argus configuration file in the helm upgrade command. Follow these steps to create configuration file:
  • Download configuration file template from here
  • Get existing values using command helm get values argus and save in backup configuration file.
  • Put all existing values in downloaded configuration file at its appropriate places. And let the remaining values at their default.
• Helm charts version for the new argus release is 1.1.0 and for collectorset-controller is 0.12.0.
  • Run helm repo update and followed by upgrade argus using command
    • helm upgrade --reuse-values -f argus-config.yaml argus logicmonitor/argus
• Recreate Argus pod if it doesn't recreate automatically. Helm does not recreate pods if there is no change in definitions.
