From YouTube: CN4J Studio - Introduction and Usage of MicroProfile Telemetry

Description

MicroProfile includes MicorProfile OpenTracing for distrubuted tracing as to implement observabilities. From the upcoming MicroProfile 6.0 release, MicroProfile OpenTracing will be replaced to MicroProfile Telemetry. In this session, I'll explain the background of the change to MicroProfile Telemetry and how it works.

A

Okay,, let's move on to the.

A

Introduction and usage of.

B

Micro-Profile telemetry by Mr. Kosaka from Fujitsu.

B

B

Profile 6.0 is scheduled to be released, and a new contract called Micro Profile Telemetry is scheduled to be added,, so I would like to introduce the contract. This time.

B

I work at Fujitsu, Ltd., Currently,, I.

B

Am mainly in charge of developing Fujitsu's Java products. Specifically, I am developing a product called Enterprise, Application Platform and a.

B

Product called Launcher. In.

B

Addition to product development, I also.

B

Contribute to the Jakarta community as a contributor. First of all, I will.

A

B

B

A

B

Explain micro-profile telemetry, I will.

B

Explain the premise of open telemetry. Making the.

B

Whole observable state becomes very important in the cloud-native world, and the main elements necessary to achieve such observability are.

B

Trace metrics logs to measure these three pieces of information. The standard specification of this will be open. Telemetry.

B

It is a specific measurement. Method, data collection, method,, format,, etc. It is summarized as necessary for measurement.It.

B

Has the feature of not, depending on a specific programming, language. Based on the poetry defined in ,.

B

Implementation libraries are provided in various languages, such as java and 5 Python.

B

Telemetry has inherited the usage of representative communities in each field. Even.

B

Now, specifications are set, and formulation is in progress.

B

Next, I will explain: micro-profile telemetry., Micro-profile telemetry.

B

Is simply the opposite of enabling open telemetry from micro-profile applications. In, the first version, 1.0, Only traces are planned to be supported.. Metrics logs are.

B

Planned to be supported after the use of open telemetry is fixed.

B

Although, it is included in the micro-profile rules,. It is possible to automatically dress the Jakarta Restful Web Service. It's possible,, but Micro Profile Open Tracing,, which is scheduled to be incorporated in Micro Profile 6.0 and has the.

B

Same tracing conventions,.

B

Will be removed from Micro, Profile 6.0 and replaced by telemetry. is.

B

Also included,, so Micro Profile also includes a contract called Micro, Profile Metrics,, but.

B

Whether this will also be integrated into telemetry in the future is currently being discussed in the community.. I would like to.

B

Explain the features of Metric 1.0. There are three main points. One is that the Open Telemetry API and TV items can be used as they are. We.

B

Use packages like IO Dot and Open TV Dot APIs. As, a basic policy,. We are proceeding with the policy of not creating micro-profile-specific.

A

B

As I said earlier, regarding the met request. Log,. The final specification is micro, We have n't, measured it on the profile side,, but it's on the implementation side.It's possible for the vendor to provide it. Independently.The third is cooperation with Micro Profile Config.When.

B

Setting up open telemetry,, for example, As you can see in the example,.

B

If you write the telemetry item in the config property file, you can set it.The above are the major features.Next, I.

B

Would like to explain.

B

How to use Micro Profile Telemetry. It can be roughly divided into two types depending on how it is used, and one is the method of using it as a library.

B

It's, a method that pushes processing into a build-intensive application called a Java agent,.

B

But there are two main types of usage.

B

Automatic instrumentation and manual instrumentation.

B

Both of these require meter support,, so you can definitely use them.

B

In, the above method,, if you.

B

Use jaxrs or micro-profile rest client on the application side,. It.

B

Will be automatically traced,, so you don't need to modify the code.

B

B

Method of writing race processing on the source code, using the API directly on the user, side.

B

This is the third agent instrumentation. So I.

B

Think whether it can be used depends on the product. You are using,, but as a method,.

B

Instead of using the Open Telemetry Micro Profile,,.

B

Attach the Java agent for the case prepared by Open Telemetry to the JBM.

B

It's, a method of automatically tracing the processing by doing it. I'd.

B

Like to explain how to use these. The source code is also enriched..

B

B

It's automatic instrumentation. As. You can see, if it is a jaxrs server or client application or a microfile rest client application,. It.

B

Can be automatically traced without using the Open Telemetry API,, but it should be noted that method calls cannot be traced., For.

B

Example,, as shown here,, the Jax RS method can be continued,, but it.

B

Is the cdib method that is called from here. This cannot be measured,. So if you want to measure it, use the manual This is a manual mention,, but this is a.

B

Method of manually, adding trace, processing using the Open Telemetry API. The.

B

Other method is to use the span builder,, which.

B

Allows you to create spans and start and.

A

B

B

Yes, last, but not least,, agent, instrumentation.

B

Attaching, a Java agent for measurement to the jvm enables automatic tracing.

B

It's easy to understand, if you look at the startup command example, written here., By.

B

Passing the JAPANAgent jar file to the option of the major command at startup, you can trace. It.It is a.

B

Major feature that you can push the measurement process into the already built application. You.

B

Can get this jar file from Open Telemetry's guitar, app, repository., It.

B

Is a method of dynamically inserting the trace code, as follows. One point to note, is that you.

B

Can not dress unless it is compatible with the libraries and frameworks supported by this Java agent. The supported list is It's written here,. So if you're interested,, please take a look.

B

B

Like to introduce you to how to actually move Open Telemetal.

B

The method to measure it is to operate it using the mention given to the agent. It.

B

Will be compliant with Micro Profile 5.0,, but we will use it to start the application.

B

Then,. We will use the Java agent, the.

B

Collectors necessary to aggregate information, and the visualization tools that visualize the aggregated, data. For collectors,. It's an Otel collector. This is the reading comprehension, image. For, the visualization tool,. It's the home, side.

B

It's, a very simple Jax, RS application that throws a request called hello first and returns: hello If you specify microprofile 5.0 as the application's dependency library,. You can.

B

Start a slightly less application. I have.

B

N't written much about the execution method here,, but as a flow,, the backend system of the application is started, and then the application is started. Since. It is.

B

Detailed on the getting status page of the.

B

Application I'll.

B

Specify the agent in the command when the application is started, and then specify the launcher demo as the service name and specify it as the trace exporter.

B

Throw a request to the application If, the request is passed to the path named hello,. The letters hello will be entered., After that,. If you access the Jaeger UI with a browser and.

B

Get a dress with the service name, Launcher Demo,: it will be successful.

B

This time, I'm posting a comparison image with micro-profile open tracing., I'm.

B

Comparing the trace information obtained with the same source code for reference. Because, the libraries being measured, are different, for example, the trace name and span Although. There are differences in details such as names, I,.

B

Think you can confirm that trace information can be obtained, basically in the same way as.

B

Micro Profile Open, Tracing. You.

B

Can easily see the trace information by linking with the cncf standard visualization tool introduced in . Thank, you very much for your.

B

A

Yes, Mr. Kosaka from Fujitsu introduced, micros profile telemetry and how to use it. Currently, micro profile has only been released up to Jakarta E 9 version,, but the next version will be released. I'm, looking forward to it,. So after this, I'd like to take a little longer break for 20 minutes until.
