system to the network equipment "pull" data into the network equipment active to the monitoring system "push" the data method?For example, a device state acquisition method that takes SNMP as an example is a pull method, called a query.This causes the network device to respond passively, because you don't know when the SNMP query will fly over, and when it comes, the network device has to allocate resources for processing.However, in a different perspective, if the use of proactive reporting, t
the near distance measurement of the object parameters is transferred to the remote measuring station to realize the long distance measurement technology. Telemetry is the use of sensor technology,a comprehensive technology of communication technology and data processing technology. Telemetry is primarily used to centrally detect dispersed or inaccessible objects, such asThe object being measured is far aw
With the increase in network size, complexity and traffic, the need for continuous and precise monitoring is greater than ever. Continuous monitoring is an important part of detecting security issues, misconfiguration, equipment failures, and the execution of traffic engineering.At the highest level, it is a push-based monitoring approach: Data plane devices, such as switches and routers, stream data about traffic and performance to the software that performs the analysis. Network

Original: Istio Source analysis--mixer Telemetry report
Statement
This article needs to understand Istio,k8s,golang,envoy,mixer basics
The analyzed environment is K8s,istio version 0.8.0
What are telemetry reports?
This article mainly introduces a GRPC interface provided by mixer, which is responsible for receiving envoy escalated logs and showing the logs in Stdio and Prometheus. The word
terminal. The working method is the same as that described earlier.
Dtp_re + d the monitoring and control terminal uses the GSM network to send alarm messages to the mobile phone number controlled by the Yamanashi through text messages. After receiving the text message, it can use its relay output signal to drive the pump controller to stop and stop, at the same time, the corresponding indicator lights are shining, and alarm messages can also be sent to the operator's mobile phone.

Suppose I have 10 lists and add a list event receiver itemadded event to these 10 lists, provided that this event provides the same functionality for all 10 lists. It is a headache to add the same event receiver to each list. If there are more than 10 event receivers in the list, copy the same event receiver n times.Code.
The following provides a method. For Mu
First, IntroductionBroadcast receiver is a broadcast receiver that receives custom and system anchors. It can also be called a listener.Broadcast intent, like intent, is the medium of communication, and unlike intent, broadcast intent is received by multiple components at the same time.Broadcast intent broadcast mechanism, broadcast sources emit messages, and through AMS (Activity Manager service), multiple

Look at the receiver of the pointer type first:

As the name suggests, braodcast receiver is a broadcast receiver. It is similar to the time processing mechanism, but the event processing mechanism is program component-level (for example, the Click Event of a button ), the broadcast event processing mechanism is system-level. We can use intent to start a component, or use the sendbroadcast () method to initiate a system-level event broadcast to transmit m
