The eleventh milestone of Hawkular released

A blog post by Heiko W.Rupp

hawkular | release

Hawkular, the monitoring platform, is happy to announce milestone release 1.0.0.Alpha11. You may perhaps wonder if you have missed Alpha 10. Don’t worry, you did not miss anything. We had an Alpha 10 build ready, but then decided to withdraw it and to bring you more features.

Running on WildFly 10 final

As announced in the last release we have rebased to WildFly 10 Final.

Tokens and QR Codes

It is now possible to generate tokens (combination of key and secret), that can be used instead of username/password as credentials. Those tokens are great to be used in the agent configuration so that no username/password is visible.

For future usage (e.g. for the Android client) it is possible to obtain a QR code, that can be scanned and which contains the token information.

APM and BTM included

Application Performance Management (APM)

The new Application Performance tab provides a breakdown of the execution performance of each component within applications deployed to the monitored servers.

The graph provides a summary per component type. The table provides a breakdown of the activity by component type, URI and optionally operation. Each row shows the elapsed and actual time spent in the component, where the elapsed time also incorporates any time spent in sub (i.e. called) components.

Business Transaction Management (BTM)

The “Business Transaction Management” capability is used to classify and monitor specific paths of execution through an organisation’s applications and services. Rather than viewing application performance just at the component level, it is possible to view information about end to end transactions.

BTM Overview
Figure 3. Tab for BTM

The Managed tab provides an overview of any configured business transactions, such as the “Booking Service” and “Events Service” above. It shows the number of transactions per hour, completion times and the number of transactions that ended with a fault.

Selecting a particular business transaction will provide a more detailed view.

BTM Details
Figure 4. BTM detail view

The top graph shows statistics, aggregated over a selected time interval, related to the business transaction instances. The details displayed are the transaction and fault counts as a bar chart, with the min, average and max completion times as a line chart.

The left hand pie chart represents the breakdown of specific fault types associated with the completed business transaction instances that ended in fault.

The right hand pie chart is used to display information about properties extracted from the business transaction instances (defined when setting up a business transaction configuration). In this specific example, the “performance id” values are being displayed.

The segments of the pie charts (fault and different properties) can be selected to filter the business transaction instances, to refine the information being viewed.

Inventory explorer

We have added a generic inventoy explorer, that allows you to browse through inventory in a hierarchical way and to pick metrics that then are displayed on the page. The metrics to be shown are stored in the browser internal database.
