KTop update and OpenDaylight MDSAL Status command!

KTop Enhancements!

We're happy to announce our latest Milestone release of the Aetos KTop command for Apache Karaf 3 based containers.

This latest revision includes:

• Improved CPU time reporting,
• Pressing q to quit,
• Sorting column change via left and right arrow keys, and
• Reverse sort by pressing r key.

Under the hood we've also made several bug fixes, and runtime performance improvements.

Sweet! How do I get this latest version?

We've published our new MileStone release to Maven Central: http://search.maven.org/#search%7Cga%7C1%7Cctop

You can also grab it from GitHub:
https://github.com/savoirtech/ctop/tags

Source tag link:
https://github.com/savoirtech/ktop/tree/ctop-0.2.0.M1

If you're using an Apache Karaf 3.0.x based system (such as Aetos 3.0.2), you can install this MileStone release using the following Karaf console command:
install -s mvn:com.savoirtech.karaf.commands/ctop/0.2.0.M1

Feedback is welcome! Please submit any ideas, enhancements, bugs to the project issue tracker: https://github.com/savoirtech/ctop/issues

So, tell us about this MDSAL Status command!

MDSAL:Status - a live feed of how MDSAL is operating.

The OpenDaylight community recently ported their project to live on top of Apache Karaf 3 with their Helium release. To help spur development of new OpenDaylight Karaf commands we've built a simple Model Driven Service Abstraction Layer status command to demonstrate how Karaf's console can empower developers and operators to create their own monitoring tools.

So what does MDSAL Status do?

The MDSAL Status commands provides an updated view of MDSAL metrics, including:

• ConfigRegistry version and health,
• DOMDataBroker statistics, and
• Metrics for CommitExecuter (CE), CommitFutureExecutor (CFE), InMemoryConfigDataStore (IMCDS), and InMemoryOperationalDataStore (IMODS).

The metrics table is of particular interest, providing live updates of ten tracked attributes, including:

• ActiveThreadCount,
• CompletedTaskCount,
• CurrentQueueSize,
• CurrentThreadPoolSize,
• LargestQueueSize,
• LargestThreadPoolSize,
• MaxQueueSize,
• MaxThreadPoolSize,
• RejectedTaskCount, and
• TotalTaskCount.

These values are obtained from MBeans provided by the OpenDaylight controller. The Karaf console provides the mechanisms to allow users to view these metrics without having to use additional external tooling.

We've published a MileStone release to Maven Central:
http://search.maven.org/#search%7Cga%7C1%7Cmdsal-status

You can also grab it from GitHub:
https://github.com/savoirtech/mdsal-status/releases

Source tag link:
https://github.com/savoirtech/mdsal-status/tree/mdsal-status-0.1.0.M1

On OpenDaylight Helium based distributions, you can install this MileStone release using the following Karaf console command:
install -s mvn:com.savoirtech.karaf.commands/mdsal-status/0.1.0.M1

How do I use MDSAL Status once installed? 

The status command requires users to have the MDSAL feature installed in their container at runtime. Once MDSAL is available, the MDSAL Status command will become functional.

To execute command on Helium, invoke:
mdsal:status

To exit status, press control + c or q to quit.

Want to see your top Apache Camel routes in a CamelContext? Try the CTop command!

Aetos Integration Platform

I've been working on a utility command for Apache Karaf based containers that will display Apache Camel Context Route metrics in a manner similar to the Linux Top command. The result has been the Aetos ctop command.

A Top like command for Apache Camel Routes, awesome!

Aetos is Savoir Technologies' Integration Platform - essentially a custom stack of raw Apache projects that makes using Apache Karaf easy for developing and running production large scale enterprise solutions.

The Aetos ctop command provides a Top like display of vital Camel Route metrics, including:

• Total Exchanges,
• Completed Exchanges
• Failed Exchanges,
• Minimun Processing Time,
• Maximum Processing Time,
• Mean Processing Time, and
• Last Processing Time

The ctop command allows users to specify which column they'd like to rank routes, and the information update interval. Use the --help option to read the command's usage information.

Sounds cool, I'd like to try it out on my Karaf system!

We've published a MileStone 1 release to Maven Central: http://search.maven.org/#search%7Cga%7C1%7Cctop

You can also grab it from GitHub:
https://github.com/savoirtech/ctop/tags

Source tag link:
https://github.com/savoirtech/ktop/tree/ctop-0.1.0.M1

If you're using an Apache Karaf 3.0.x based system (such as Aetos 3.0.2), you can install MileStone 1 using the following Karaf console command:
install -s mvn:com.savoirtech.karaf.commands/ctop/0.1.0.M1

Feedback is welcome! Please submit any ideas, enhancements, bugs to the project issue tracker: https://github.com/savoirtech/ctop/issues

How do I get the code?

git clone https://github.com/savoirtech/ctop.git

Currently, the command is aimed at Apache Karaf 3 & 4 containers. If community interest exists, we'll port it back to Karaf 2.3 & 2.4.

How do I build and install ctop into my container?

To build, invoke:

mvn install

To install in Karaf, invoke from Karaf console:

install -s mvn:com.savoirtech.karaf.commands/ctop/version-SNAPSHOT

How do I use ctop once installed?

The CTop command requires users to have the Apache Camel feature installed in their container at runtime. Once Camel is available, the CTop command will become functional.

To execute command on Karaf, invoke:

aetos:ctop CamelContextName

To exit ctop, press control + c


The code is under the GNU license at the moment, as per a project requirement -- we will have it under the ASL in the future. In the mean time if you're looking for a way to monitor your Camel Routes from your console window, give Aetos ctop a try!

Want to see how your Karaf container is performing? Try the ktop command.

Aetos Integration Platform

I've been working on a utility command for Apache Karaf based containers that will display JVM usage metrics in a manner similar to the Linux Top command. The result has been the Aetos ktop command.

Aetos is Savoir Technologies' Integration Platform - essentially a custom stack of raw Apache projects that makes using Apache Karaf easy for developing and running production large scale enterprise solutions.

JVM vital statics in a Karaf console - awesome!

The Aetos ktop command provides a Top like display of vital JVM metrics, including:

• Basic platform details.
• JVM Uptime.
• JVM Thread counts.
• Garbage Collector Stats.
• ClassLoader Stats.
• JVM Memory Stats, and
• Periodically updated top threads by CPU usage. 

The ktop command allows users to specify how many threads they'd like displayed, and the information update interval. Use the --help option to read the command's usage information.

Sounds cool, I'd like to try it out on my Karaf system!

We've published a MileStone 1 release to Maven Central:

https://github.com/savoirtech/ktop/tree/ktop-0.1.0.M1

If you're using an Apache Karaf 3.0.x based system (such as OpenDaylight Helium or Aetos 3.0.2), you can install MileStone 1 using the following Karaf console command:

install -s mvn:com.savoirtech.karaf.commands/ktop/0.1.0.M1

Nice! I'd like to have the command on a different Karaf platform...

There are three branches of the Aetos ktop project at this time, tracking Apache Karaf 2.3.x,  3.0.x, and 4.0.x lines. At current, users will have to clone the source repo, checkout the branch appropriate to their Karaf deployment, and build the code locally before installing in their container. Please use the following instructions to get ktop running on your container:

How do I get the code?

git clone https://github.com/savoirtech/ktop.git
cd ktop
git checkout k23x | k30x | master

The k23x branch is maintained for Karaf 2.3.x format, k30x for Karaf 3.0.x format, and master will track Karaf 4 style commands.

How do I build and install ktop into my container?

To build, invoke:

mvn install

To install in Karaf, invoke from Karaf console:

install -s mvn:com.savoirtech.karaf.commands/ktop/version-SNAPSHOT

How do I use ktop once installed?

To execute command on Karaf, invoke:

aetos:ktop

To exit ktop, press control + c


The code is under the GNU license at the moment, as per a project requirement -- we will have it under the ASL in the future. In the mean time if you're looking for a way to monitor your Karaf container from your console window, give Aetos ktop a try!
