Corrections and suggestions on Explorer for android client
by Anuj Garg
Hello everyone,
A tree structure of the explorer is approx ready for the android client and
I was curious if i am wrong somewhere.
First of all, All feeds are collected by call to
/inventory/feeds
feed call for resources
/inventory/feeds/{feed}/resources
call for rec resources and metrics
/inventory/feeds/{feed}/resources/{resid}/recursiveChildren
/inventory/{feed}/resources/{resid}/metrics
Am I missing something?
Thanks

Mastering the Art of Academic Writing
by derek jackson
Developing strong writing skills is essential for students striving for academic success. Crafting well-structured essays, term papers, and research projects requires not only knowledge of the subject but also the ability to present arguments clearly and persuasively. Understanding Essay Writing Techniques and Tips can significantly improve the quality of written work.
One of the most important aspects of academic writing is planning. Before starting, students should carefully analyze the assignment requirements, identify key points, and create an outline. This helps organize thoughts and ensures that the paper flows logically from introduction to conclusion. A well-structured outline provides a roadmap, making the writing process more efficient and less overwhelming.
Research plays a crucial role in creating high-quality academic papers. Reliable sources, such as academic journals, books, and credible websites, provide the necessary evidence to support arguments. It is important to evaluate sources critically, ensuring they are relevant and up to date https://writepaperfor.me/blog/business-essay-topics . Taking detailed notes while researching helps in structuring the paper and avoiding plagiarism.
A strong introduction is the foundation of any well-written essay. It should grab the reader’s attention, introduce the topic, and present a clear thesis statement. The thesis acts as the central argument, guiding the rest of the paper. Each body paragraph should focus on a single idea, supported by evidence and logical reasoning. Connecting ideas smoothly enhances readability and coherence.
For students working on business essay topics, clarity and precision are key. Business-related papers often require analyzing case studies, industry trends, and financial data. Using clear language, avoiding unnecessary jargon, and structuring the content effectively are essential for presenting a well-reasoned argument. Additionally, referencing credible business sources strengthens the validity of claims.
Editing and proofreading are critical steps in the writing process. After completing a draft, students should take time to revise their work, checking for clarity, coherence, and grammatical errors. Reading the paper aloud can help identify awkward phrasing and inconsistencies. Seeking feedback from peers or using writing tools can further refine the final draft.
Proper citation is essential in academic writing. Different institutions and disciplines require specific citation styles, such as APA, MLA, or Chicago. Correctly citing sources not only gives credit to original authors but also demonstrates academic integrity. Keeping track of references during research makes it easier to format citations correctly in the final version.
Time management is another key factor in successful academic writing. Procrastination often leads to rushed work and lower-quality essays. Setting realistic deadlines for each stage of the writing process—research, drafting, revising, and finalizing—helps students stay on track. Allocating sufficient time for each phase ensures a well-developed and polished paper.
By applying effective Essay Writing Techniques and Tips, students can enhance their writing skills and produce high-quality academic work. Developing a structured approach, conducting thorough research, refining arguments, and managing time efficiently all contribute to academic success. With practice and dedication, mastering academic writing becomes a valuable skill that benefits students throughout their educational journey.

some new hawkular openshift agent stuff
by John Mazzitelli
FYI: some new things went into HOSA (that's the Hawkular OpenShift Agent for the uninitiated).
1. The agent now emits its own metrics and can monitor itself. Right now it just emits some basic "go" metrics like memory usage, CPU usage, etc along with one agent-specific one - a counter that counts the number of data points it has collected in its lifetime. We'll add more metrics as we figure out the things people want to see, but we have the infrastructure in place now.
2. The agent is deployed as a daemonset. This means as new nodes are brought online, an agent will go along with it (or so I'm told :)
3. The agent has changed the way it discovers what to monitor - it no longer looks at annotations on pods to determine where the configmaps are for those pods. Instead, it looks up volume declarations to see if there is an agent configmap defined. This was done to be ready for the future when new security constraints will be introduced in OpenShift which would have broken our annotation approach. This approach using volumes should not hit that issue.
NOTE: If you are building the latest agent from master, we added some dependencies so you have to update your dependencies via Glide by using the "make update-deps" target prior to building from source.

Error connecting to Cassandra - com.datastax.driver.core.exceptions.InvalidQueryException
by Dhillon, Manjot
Hello, I am trying to start hawkular services, version hawkular-1.0.0.Alpha13-SNAPSHOT.
As per the documentation, I am using Cassandra version 3.0.12. On starting the hawkular service, I see the following error -
33m01:58:08,209 WARN [org.hawkular.alerts.engine.impl.CassDefinitionsServiceImpl] (Thread-239 (ActiveMQ-client-global-threads-15127043)) Could not connect to Cassandra cluster - assuming is not up yet. Cause: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: apsrd6612.uhc.com/10.204.85.28:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces))
The cassandra driver included with the hawkular service - cassandra-driver-core-2.2.0-rc3.jar, which may be causing the issue.
Thanks,
Manjot

logging in java agents is not trivial in WildFly / EAP
by John Mazzitelli
<tl;dr>
No matter if a java agent uses JBoss Logging or simply relies on the JRE's own Java logging, it still won't work in WildFly/EAP unless you set additional things to environment variables in standalone.conf. So no matter what logging is used, this means problems still need to be overcome when putting java agents in host controllers for EAP 7.0 domain mode.
</tl;dr>
I am looking at how Java Agents should log messages when attached to WildFly or EAP. I want to see if there is a way to implement a Java Agent and NOT have to set any special JAVA_OPTS values to pass to the VM to get it to work.
Turns out, it is not a trivial issue.
I wrote a silly little test agent [1] just to see what would happen if it simply logs a message using *java* logging and spins a thread logging a message every second again using *java* logging. So, no extra third party logging libraries, just using java.util.logging classes that are in the JRE already.
Adding just -javaagent to JAVA_OPTS (in standalone.conf, add something like "-javaagent:/where/it/is/ja.jar=foo=bar") is no good, the server bombs with this error, presumably because my agent already started logging using java logger:
Caused by: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: WFLYLOG0078: The logging subsystem requires the log manager to be org.jboss.logmanager.LogManager. The subsystem has not be initialized and cannot be used. To use JBoss Log Manager you must add the system property "java.util.logging.manager" and set it to "org.jboss.logmanager.LogManager"
Well, catch-22, because if I set java.util.logging.manager=org.jboss.logmanager.LogManager in JAVA_OPTS, this happens when the test agent tries to log:
Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.LogManager
which then falls back to java logging, which then causes the server to bomb again because it wants JBoss Logging.
If I set this in standalone.conf:
JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman,org.jboss.logmanager"
the java agent still gets this error:
Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.LogManager
which is then followed by jboss modules error which causes the server to again to fail to start:
WARNING: Failed to load the specified log manager class org.jboss.logmanager.LogManager
Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/logmanager/Level
...
at org.jboss.modules.Module.run(Module.java:320)
The ONLY way to get the server to start properly with this java agent installed (EVEN WITH the agent using ONLY java logging), you have to do all of the above plus add this to JAVA_OPTS:
-Xbootclasspath/p:$JBOSS_HOME/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.0.4.Final.jar
So, in short, you need to add "-Djava.util.logging.manager=org.jboss.logmanager.LogManager" to JAVA_OPTS, you need to add ",org.jboss.logmanager" to JBOSS_MODULES_SYSTEM_PKGS, and you need to add that -Xbootclasspath to JAVA_OPTS just to get a javaagent to work even if the javaagent simply uses nothing more than standard java logging.

[1] $ cat JavaAgent.java
import java.util.logging.*;
public class JavaAgent {
private static final Logger log = Logger.getLogger(JavaAgent.class.getName());
public static void premain(String args) {
log.severe("log in premain: " + args);
new Thread(new Runnable() {
public void run() {
while (true) {
try {
Thread.sleep(1000);
log.severe("log in premain loop: " + args);
} catch (Exception e) {
return;
}
}
}
}).start();
}
}
To build it:
$ echo "Premain-Class: JavaAgent" > manifest.mf
$ javac JavaAgent.java
$ jar cvfm ja.jar manifest.mf JavaAgent*
