ActiveSpaces Hawk Microagent Methods Overview

The TIBCO ActiveSpaces Hawk Microagent provides the following categories of monitoring methods:

  • Space and Member Statistics
  • Space and Member Distributions
  • Space Operation Throughput at Application Level
  • Space Definition Events
  • Metaspace Member and Space Member Events
  • Console and File Logging Management
  • Space Management

From the TIBCO Hawk display, select a TIBCO Hawk Microagent. The microagent displays all the methods exposed for monitoring the Metaspace cluster. You can typically invoke for on-demand request to get the result interactively. You can also subscribe to the exposed methods specifying the data delivery polling interval. Data delivery interval for Space Definition and Member events are not required as it is instrumented based on ActiveSpaces Event Listener. In the case of a subscription, it allows you to create a monitoring rule for building a Hawk rulebase.

  • Space and Member Statistics Methods
    The Space Member statistics methods return the result either on a single row or multiple rows.
  • Space Distribution Methods
    The Space and Member Distribution methods return the percentage distribution of the data either grouped by the Space Members of a Space or grouped by Spaces of a Member. You can monitor the distribution of data across Members of a Space. Or you can monitor the distribution of Space entries stored grouped by Members.
  • Space Operation Throughput at Application Level Methods
    The Space Operation Throughput methods provide the application level throughput based on the changes of the result attributes over the data delivery interval.
  • Space Definition Events Methods
    The Definition Event methods provide an event driven subscription service that allows the monitoring of new Space defined or when a Space is dropped or altered. It reports all the Spaces Definitions in multiple result rows when any Space event.
  • Metaspace Member and Space Member Events Methods
    The Metaspace Member and Space Member Events methods provide an event driven subscription service that allows the monitoring of Members joining and leaving the Metaspace or a Space. It reports all the Members of the Metaspace or all the Space Members of a Space along with the attributes of the reported Members when any Member event happens. The additional member attributes also allows you to monitor when a Metaspace Member changes the Manager Role or when a Space Member changes its Distribution Role between Seeder and Leech.
  • Console and File Logging Management Methods
    The Console and File Logging Management methods provide management functionality for console logging and file logging.
  • Space Management Methods
    The Space Management methods provide space management functionality.
