CPU: percentage of limit

A lot of people land when trying to find out how to calculate CPU usage metric correctly in prometheus, myself included! So I'll post what I eventually ended up using as I think it's still a little difficult trying to tie together all the snippets of info here and elsewhere.

This is specific to k8s and containers that have CPU limits set.

To show CPU usage as a percentage of the limit given to the container, this is the Prometheus query we used to create nice graphs in Grafana:

sum(rate(container_cpu_usage_seconds_total{name!~".*prometheus.*", image!="", container_name!="POD"}[5m])) by (pod_name, container_name) /

Scaling k8s daemonset down to zero

kubectl -n kube-system patch daemonset myDaemonset -p '{"spec": {"template": {"spec": {"nodeSelector": {"non-existing": "true"}}}}}'

Scaling up k8s daemonset

kubectl -n kube-system patch daemonset myDaemonset --type json -p='[{"op": "remove", "path": "/spec/template/spec/nodeSelector/non-existing"}]'

Scaling k8s daemonset down to zero

kubectl -n kube-system patch daemonset myDaemonset -p '{"spec": {"template": {"spec": {"nodeSelector": {"non-existing": "true"}}}}}'

Scaling up k8s daemonset

kubectl -n kube-system patch daemonset myDaemonset --type json -p='[{"op": "remove", "path": "/spec/template/spec/nodeSelector/non-existing"}]'

Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

2019-06-03

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.

Hexadecimal color code for transparency

How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.
