What is the real time use of actuators? How can you hide the sensitive information shown in /env

[@TechPrimers]

You can use it for Monitoring the Health of your Application and for collecting information about the application. You can write custom Heath Indicators and disable /env since it exposes sensitive info.

[@she1212]

Thanks for the reply. Here's what i did for my app As recommended in docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html I tried putting this in application.properties "endpoints.env.keys-to-sanitize=password,secret,key,token,.*credentials.*,vcap_services # Keys that should be sanitized. Keys can be simple strings that the property ends with or regex expressions." But i did not see any key/password removed from /env. So I completely disabled the endpoints using endpoints.enabled=false, And enabled only health and info.

[@bahdanshyshkin7918]

I think you are doing a great work because you save a lot of developer's time which they would spend researching and reading docs. Big respect)

[@TechPrimers]

Thanks mate. Glad that was helpful

[@maclovesgeet]

Awesome work. One tip.. you may like to edit away the clip which is not required in the final video. E.g searching for downloaded zip. This will shorten the length of the video and will remain crisp and clear. Anyways.. keep up the good work.

[@melsaied101]

Thank you for you effort

[@ankitagarwal969]

[@sun-prairie]

[@deepaksahoo4175]

I still feel Boot Admin is a better way of handling all actuator (rest)end points. Because in its admin is a graphical UI

[@AzamKhan-uw1bg]

I am thankful to you for describing actutor , please describe about WebAppInitializer and SpringBootServletInitializer

[@rajeshreddy5614]

Hey i want change data source properties on the fly. Using spring config . Plz make a vedio for that.

[@bathulanagendra4621]

Hi ajay.if I used actuator in my project it is saying that unsatisfied dependency expressed through method entityManagerFactoryBuilder.Bean creation exception is coming.if I removed that dependency it was working fine.how to resolve this issue.

[@kranthisingh1749]

Okay so , If I want to use the Actuators data to push to some monitoring tool how do I do that. Is it possible??

[@omkarpidde8144]

I think you have to restart the application.... Changes from pom.xml file will not be reflected, until it is restarted

[@krishnendughosh1212]

Can you please show us how logging can be done in spring boot so that all the request and response can be logged .

[@TechPrimers]

+krishnendu ghosh sure

[@nareshe9906]

By default I want to allow the info ,health actuator endpoints and other end points need to be authenticated with some credentials . How to do the same. ?

[@sujithg5873]

Nice video.How to get a custom variable value in a controller from application.properties

[@TechPrimers]

[@sujithg5873]

Tech Primers Thank you so much

[@user-ok9wv9tf6h]

If u use Spring Boot Version more than 2.0 management.endpoint.health.show-details=always management.endpoints.web.exposure.include=* management.endpoint.beans.enabled=true

[@Explore-world-]

Its not working with latest version (2.6.2). May be outdated tutorial??

[@HimanshuTibrewal]

Your username is blank in the properties file, update properties file with the correct username and password.

[@sujithg5873]

How can we use actuators in real project?this case anybody can access this information.But I want to limit for some people.Is it possible? Could u help me sir

[@TechPrimers]

+Sujith G yes. U need to use Spring Security to secure your end points by adding authentication & Authorization filters.

[@elibely]

great work but please kill the music, i think if i want music i can have another video playing alongside

[@nedu-n-chezhian9324]

That's rude

[@ashwinibalakrishnan9672]

Can you explain what is meant by health check and metrics

[@proxy5061]

Every application, enterprise , business applications need continues monitoring about the cache, database is working or not, all the APIs are working or not so we need that !

Background music is too loud and it's dominating

[@sathiits]

I couldn’t find the Endpoint interface from actuator dependency instead I’m seeing EndpointSupplier

[@sathiits]

I’m using 1.5.6 spring boot

[@TechPrimers]

Yes it's changed in the recent spring boot version

[@ashishagrawal7709]

Thanks but why music in background, its disturbing

[@trapslime16]

The only bad thing is that music was to quiet, i could almost hear you talk

[@khimaanshu9]

Tutorial is good, but the background music is irritating.

[@waziharaa]

Please remove the Background noise. Irritating
