Chapter 1: Layering

A basic example of layering: FTP < TCP < IP < Ethernet

Benefis of layering:

You can understand a layer without knowing much about the others.
Minimize dependencies.

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048
    
# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)
openssl ecparam -genkey -name secp384r1 -out server.key

	Recording Rule Example 1
	================================
	# Aggregating up requests per second that has a path label:
	- record: instance_path:requests:rate5m
	expr: rate(requests_total{job="myjob"}[5m])

	- record: path:requests:rate5m
	expr: sum without (instance)(instance_path:requests:rate5m{job="myjob"})

	Recording Rule Example 2

+# Add field
+echo '{"hello": "world"}' | jq --arg foo bar '. + {foo: $foo}'
+# {
+#   "hello": "world",
+#   "foo": "bar"
+# }
+# Override field value
+echo '{"hello": "world"}' | jq --arg foo bar '. + {hello: $foo}'
+{

	abc 1 2 3
	def 4 5 6
	ga 7 9 10
	hij 1 5 99

	Call the api client like this:

	var client = new ApiClient<SEnvelope>("https://baseurl.com/api/v1");
	//you would overload and add an auth_token param here
	client.GetDtoAsync("envelopes", "object_id", (response) => //callback
	{
	this.SEnvelope = response.Data;//should be an envelope from the server
	});
