Few days ago I moved from Xchat to hexChat IRC client. Among it's cool feature I was hoping to find support for reading/searching channel/PM log files. Sometimes I remember "oh I was discussing it with this guy". Then I have to go to terminal, look for the right log file and go through it to find what I am looking for.

Deploy a bundle to RHQ with 10 lines of code using rhqapi.js
It's been a while ago, since I wrote rhqapi.js library that is being extensively consumed by RHQ QE team. Now I decided to push it to RHQ, so it can help as CLI module. This article tries to show how easy it is to deploy a bundle with rhqapi.js
In our example we'll write a simple script, that could run repeatedly and will upload & deploy our bundle to group of Linux platforms.
We'll need rhqapi.js (as it is not yet part RHQ CLI) and we'll add it to modules
Download the script and bundle and put it in rhq-remoting-cli-4.13.0-SNAPSHOT/bin.
Run:
In our example we'll write a simple script, that could run repeatedly and will upload & deploy our bundle to group of Linux platforms.
- we need RHQ Bundle - simple bundle which just contains 1 file to be laid down
- upload it to RHQ Server
- create group of all Linux platforms (or skip if it already existed)
- deploy our bundle - in case our bundle with given version already exists on server, it will just be redeployed
We'll need rhqapi.js (as it is not yet part RHQ CLI) and we'll add it to modules
cd rhq-remoting-cli-4.13.0-SNAPSHOT; wget https://raw.githubusercontent.com/rhq-project/samples/master/cli/rhqapi/rhqapi.js -O samples/modules/rhqapi.js
The script:
Download the script and bundle and put it in rhq-remoting-cli-4.13.0-SNAPSHOT/bin.
Run:
./rhq-cli.sh -u rhqadmin -p rhqadmin -f deploy-bundle.js Logging in with default host: [localhost] Logging in with default port: [7080] Remote server version is: 4.13.0-SNAPSHOT (26fc58f) Login successful Bundle uploaded to server 16:08:14 [INFO] Creating a group 'LinuxPlatformsGroup', with following children: '[10001] localhost.localdomain (Linux::Platforms)' 16:08:14 [INFO] Parameter baseName was not passed, using default : Root File System Created bundle destination targetting to /tmp of 1 Linux platforms Deploying to LinuxPlatforms PageList[BundleVersion[id=10002,name=SampleBundle,version=1.0]] 16:08:25 [INFO] Bundle deployment finished with status : Success Bundle has been deployed
There's more
rhqapi.js is much more powerful, there's set of examples on github and also JSDoc documentationpátek 31. října 2014
Wildfly Extension Installer - maven plugin
I recently started to play with RHQ Metrics, especially WildFly Monitor subsystem. One thing I found annoying was copying over module to WildFly and registering it as server extension. As WildFly does not (yet) support adding extensions at runtime, I decided to write a maven plugin for it.
Plugin features
- Install module - this is an easy one.Plugin requires a module zip file and just extracts it into your WF home.
- Register extension - your module gets automatically added among server extensions
- Register subsystem - if you supply subsystem xml file, plugin puts it's content to right place
- Register socket-binding - if your subsystem requires to set socket binding and you supply socket-binding xml file, plugin puts it's content to right place
- Support for domain.xml - all above applies to domain.xml as well, for subsystem and socket-bindings you just need to provide wich profiles and socket-binding-groups to affect.
Example usage
Prepare your module.zip (ie. using maven-assembly-plugin) see for example pom.xml and module-assembly.xml from wildfly-monitor project.
Setup your build:
Setup your build:
Run plugin:
mvn wildfly-extension:deploy
Possible future enhancements
- Restart server - plugin could optionally restart WildFly server after it has installed module and registered all stuff
- Extract module only - add option to extract module without registering an extension
- Assemble module - based on configuration and maven depenencies, plugin could generate module.xml and collect all required jars or directories
- Add a way to uninstall module and extension from WildFly server
