Salve omnes β haec est quintae postes in serie nostra Quarkus! (Viam nostram vigilate webinar . Ostendam tibi quomodo incipias a scabere vel transferre solutiones paratas)
Π inspeximus applicationes Javae modernisandi utentes Quarkus technologias (CDI et Servlet 3) utentes programmata helloworld ex reposito in exemplum . Hodie de argumento modernizationis et de casu memoriae de consummatione pergamus.
Mensuratio euismod est fundamentum fundamentale paene ullius upgrade, et memoria usus renuntiationis magna pars est processus analyseos perficiendi. Hodie spectabimus ad instrumenta mensurae pertinentes quae ad emendationes per applicationes Javae modernisandi effectas adhiberi possunt.
Plura de usu memoriae metiendis vide Quarkus intitulari
Infra solum ostendemus te memoriam usus notitiarum comparare pro tribus generibus applicationum (JBoss EAP, UAR fasciculi et exsecutabilis) colligendo notitias in Linux utentes utilitates pmap et ps.
JBoss EAP
Exemplum de applicatione JBoss EAP deducimus (vide sectionem "Deploying helloworld" in ) ac deinde processum eius PID (in exemplo nostro est 7268) spectare, utens mandato sequenti:
$ pgrep -lf jboss
7268 java
Nota. Optio -a tibi permittit ut rectam mandatum integrum extrahat (ie: $pgrep -af jboss).
Utimur autem PID 7268 in ps et pmap praeceptis.
Ecce quomodo;
$ ps -o pid,rss,command -p 7268
PID RSS COMMAND
7268 665348 java -D[Standalone] -server -verbose:gc -Xloggc:/home/mrizzi/Tools/jboss-eap-7.2.0/jboss-eap-7.2/standalone/log/gc.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=3M -XX:-TraceClassUnloading -Xms1303m -Xmx1303m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferI
Et sic:
$ pmap -x 7268

Respicimus valorem RSS et videamus JBoss EAP proxime 650 MB memoriae consumere.
URNA sarcina
Urnam applicationis deducunt (vide sectionem "Furre helloworld packaged in URNA" in ):
$ java -jar ./target/helloworld-<version>-runner.jar
Respicimus PID iterum utendo imperio pgrep (hoc tempore utimur optio -a de qua supra);
$ pgrep -af helloworld
6408 java -jar ./target/helloworld-<version>-runner.jar
Currimus ps et pmap ut metiamur usu memoriae, nunc ad processum 6408 .

Respicimus Corpus RSS et perspicimus documentum exsecutabile circa 20 MB memoriae capere.
Memoria consummatio comparet
Numeros itaque sequentes memoriae pro usu assecuti sumus;
- JBos EAP β 650 MB.
- URNA sarcina β 130 MB.
- Fasciculus exsecutabilis - 20 MB.
Patet, quod documentum exsecutabile multo minus memoriam suscipit.

In hoc et in praecedentibus stationibus recentiores applicationes Javae utentes technologiae in Quarkus (CDI et Servlet 3) inspeximus, necnon variis modis ad huiusmodi applicationes ad explicandum, aedificandum et currendum. Ostendimus quomodo notitias ad memoriam colligendam adhibeamus ad aestimandas emendationes tali upgrade effectas. Articuli istos adiuvant ut scias quomodo Quarkus operatur et cur utile est, sive dicis de programmate simplici helloworld in exemplis nostris vel multo magis implicatis applicationibus realibus vitae.
In duabus septimanis revertemur cum finali cursore de Quarkus - ibi te vide!
In nostra finali statione, ostendemus quomodo AMQ Online et Quarkus coniungendae sint ad aedificandum modernos systematis nuntii OpenShift fundati utentes duas technologias novas nuntiandi. Read on .
