Service Profiler Snapshot Collector

Bug Corrections:

• Property defaults were not being automatically forced to be saved.

  Together with the fact that defaults were not being shared between the properties editing page and the scheduled processes, this could reflect negativelly in the Purger process having it deleting snapshots just older than 2 Weeks instead of older that 18 Months.

  A quick fix would be going to the properties editing page and just click the [Save] button. This stores the defaults and corrects the issue.

  This new version of the package tool now does this automatically when it is (re)loaded.

• On the properties editing page, the description of for the Compactor's' 'same month' Retention Unit was incorrect.

  The description was equal to the textbox caption.

• The Compactor process was using the same 'value' property for 'same week' and 'same month'.

  When using the defaults, this had no practical influence because they have the same value ('2').

  But, if you changed those defaults the results could not match the expectations.

Bug Corrections:

• Fail to save gathered snapshots for a server without an already created folder.

  This could happen after adding new servers as Remote Aliases.

  The server would be listed but no snapshot would be created for it.

  Additionally, an error would be logged to the server log, like:

  [ISS.0098.0049C] Exception:com.wm.app.b2b.server.ServiceException: packages.var/WiaServiceProfiler_Collector/repository/<uuid>.server/<uuid>.xml (No such file or directory) while executing trigger. Rejecting Document for TriggerStore:wia.isspscoll.scheduled.gatherer:GatheredResultSubscriber.

This version introduces the online help and enhances included information.

New Features:

• Added the possibility of removing a server from the repository;

  This is usefull to reclaim hard disk space, when clearing no longer relevant information about deactivated servers;

• Complete set of included documentation.

Other Corrections:

• Corrections to HTML for better compliance with standards;
• Corrections to CSS;
• Force load of repository manifest properties on package reload.

Bug Corrections:

• The Go button on the Server Selection page was not appearing when the Service Profiler license was valid;
• The Go on the Server Selection button never resulted in a list of snapshots;
• The selectable check-boxes on the Server Selection were showing even if the license was invalid.

New Features:

• Service Profiler License Key remote management.

Other Corrections:

• Adapt to use with webMethods v9.10.

  Keep compatibility with previous versions of the platform while keeping a webMethods v8.x look.

New Features:

• Visually identify which servers are actively being collected to clearly distinguish from those that are no longer being collected.

New Features:

• The snapshot gathering service used in the scheduler can now be configured do also do a counters reset.
• Allow querying servers that are no longer being collected.

  The list of servers was being based on the list of defined Remote Aliases. This way, only servers being actively collected could be viewed. If a server were to be decommissioned, the Remote Alias had to be deleted and its snapshot history could no longer be viewed.

  By basing the list of server on the list of registered servers, these can still be viewed... while no longer collected.

Other Corrections:

• Improve snapshot selection based on start/end date range.

Bug Corrections:

• Compactor: the delete snapshot service no longer deletes the file;

  Must delete the files... but optionally.

• Compactor: reference list of servers is against registered servers and not defined aliases.

  Otherwise, servers in repository that are discontinued or otherwise removed form the list of aliases will never be compacted again.

Other Corrections:

• Improved concurrent access to snapshot files;
• When the snapshot has the same start date of the last snapshot, do not create a new one and delete the last one.

  Replace existing XML file with same UUID.

Bug Corrections:

• Compactor would not process Quarter Grouping.

Continue improving the used interface with new DSPs and options.

New Features:

• Extra error information when snapshots fail to merge.

Bug Corrections:

• Using wrong service name to list the selectable server for viewing;
• Try to reduce snapshot reading errors on the Compactor process by automatically retrying.

Continue improving the used interface with new DSPs and options.

New Features:

• Select and merge snapshots from multiple servers.
• Manage multiple gatherer tasks.

Bug Corrections:

• The state of the Purger task was not being correctly managed;
• The closing of the evaluation cycles on the Compactor process was not considering the Grouping Types.

Continue improving the used interface with new DSPs and options.

New Features:

• Added the Snapshot Compactor services and task.

Continue improving the used interface with new DSPs and options.

New Features:

• Added the Purger services and task;
• Autimatically suspend the tasks when the package is unloaded;
• Save & Restore scheduled tasks state on package reload;
• Replaced some hardcoded settings for values in properties;
• Add editable configuration settings as properties;
• Allow launching the Gatherer immediately and from the GUI.

Bug Corrections:

• When the startup service runs for the first time, only one of the tasks would be created.

Other Corrections:

• Corrections to HTML for better compliance with standards;
• Corrections to CSS.

First working version.

Out of necessity, at a customer's assigment, even though the snapshots were being collected to an indexed BD (in more that one way), some history of the Service Profiler snapshots was required to be readily available for consultation, at least for a seleted set of Integration Servers.

The only requirement was to be able to view the snapshots. So, using the feature of the Service Profiler to load and visualize snapshots exported as XML from other Integration Servers, all that was needed was some scheduler getting the snapshot remotelly and store it locally for offline viewing.

The collected snapshots have to be stored in some organized manner so they can be correctly identified, listed and selected for viewing. A file based repository was created for that purpose, with a properties based manifest for its internal organization. The location of the repository files is being managed out-of-the-package via the WiaRuntimeEcosystem package services.

This first version basically:

• Creates a Scheduled Task;

  The task is autmatically created upon installation of the tool.

• The task periodically gathers the snapshots remotelly and stores them into the repository.
• From the local repository, the gathered snapshots are selectable and loaded into a locally installed Service Profiler for viewing and analyzing.
