This release includes a lot of usability improvements for troubleshooting and configuring Collectord, and monitoring your clusters.
Using Cores/Milli-cores in the dashboards instead of percents
When we built the first versions of our dashboards, we used similar to the Linux
top command values to show the CPU
usage of the containers and pods. In that case, if one of the containers uses 2CPU cores, our dashboards will show
However, with the time we have found, it isn't obvious for our customers, as they define the limits and requests with the concept
of milli-cores (or cores), and it takes some time to adjust to the percent values.
With version 5.17 we have changed the values of CPU usage from percent to cores. Instead of showing
199% (almost 2 CPU usage),
we now show
1.990 (almost two cores are used). We keep percents only when we show Usage relative to Requests or Limits.
Resource Quotas monitoring
We have updated ConfigMap to watch the ResourceQuotas defined in the cluster and built a dashboard to monitor the usage. To use the Resource Quotas dashboard (under Review), make sure to configure watching those objects with ConfigMap. Please use the latest ConfigMap from the installation instructions to see how it needs to be defined.
Update for the Clusters dashboard
We significantly updated the Clusters dashboards to include more information about the Limits, Requests, and Usage, so you can look overtime at the maximum CPU Limit or Usage and plan your clusters' capacity.
Starting with version 5.17 you can point Collectord to the remote HTTP server to download the license key. That way, if you are managing more than one cluster, it takes only a change in one place to update the license on all of your clusters.
You can use a custom HTTP server or an instance of Collectord to distribute the license. Please read how to configure the license server in your environments by following the links below
