Monitoring

Updating Monitoring Configuration for your Kubernetes Cluster

When you initially add your cluster into monitoring via the ‘Add Kubernetes Cluster’ wizard, you configure various aspects of monitoring (Collector size, whether Kubernetes RBAC is enbabled, how many Collector replicas you want, etc.) and LogicMonitor provides you with Helm commands that enable install matching your configuration:


This wizard is not available after adding your cluster into monitoring. If you need to change one of these configuration items later (after going through the wizard), the most straightforward way to do so is via Helm directly in your cluster. Specifically, you’ll need to upgrade your Helm release for Argus and/or the Collectorset-Controller and change the desired options. We recommend using the --reuse-values flag during that upgrade to ensure previous options that aren’t changed remain as-is. You can see all available configuration options for Argus here, and for the Collectorset-Controller here. For example, to update the number of Collector replicas to ‘2’, you might run the following in your cluster:

helm upgrade --reuse-values --recreate-pods --set collector.replicas="2" argus logicmonitor/argus


You can also use Helm to view the current configuration for the Argus & Collectorset-Controller releases, which may be helpful prior to making changes:

helm get values argus


Note that LogicMonitor does update Helm Charts for certain releases. To ensure you have the latest charts in your cluster, it is a good idea to run the following command prior to making updates:

helm repo update
