Use

The Queue Landscape tab page displays information on the queue distribution. This tab page is only relevant for distributed TREX systems and only if indexing is done using a queue server.

Features

The queue distribution is displayed as a table. There is a separate row for each queue. The columns contain the following information:

Column

Description

Queue ID

Name of the queue.

Status

Displays which server is currently active for the queue - the master queue server or the backup queue server.

<hostname>: <queueserver_port>

Displays the queue server status and the role of the server in relation to the queue.

The queue server status is displayed as follows:

  • Green or active

    Server is available

  • Yellow or unknown

    The name server does not know the server status. The server receives this status in the start phase. If the name server can reach the server, it changes the light to green. If not, it changes the light to red.

  • Red or inactive

    Sever is not available

The role of the queue server is displayed as follows:

  • +master

    This is the master queue server for the queue. The plus sign indicates that this server is currently active.

  • -master

    This is the master queue server for the queue. The minus sign indicates that the server is currently not active, for example, because it is not available.

  • +backup

    This is the backup queue server for the queue. The plus sign indicates that this server is currently active.

    This situation occurs if the master queue server has failed and a switch to the backup queue server has taken place.

  • -backup

    This is the backup queue server for the queue. The minus sign indicates that this server is currently not active.
