indexerinfo XML status report syntax (FAST Search Server 2010 for SharePoint)

FAST Search Server 2010
 

Applies to: FAST Search Server 2010

Topic Last Modified: 2011-03-14

The indexerinfo status command retrieves an XML-formatted report for the Microsoft FAST Search Server 2010 for SharePoint indexer status. This article describes the syntax of the report.

The report uses the following elements:

 

Element Description

<indexer>

This top-level element specifies the overall status of the indexer.

<documents>

This element shows information about indexed items.

<column_role>

This element specifies the role of an indexer in an index column.

<index_frequence>

This element shows the number of items indexed per second.

<partition>

This element shows information for one index partition.

<partition/documents>

This element shows the number of indexed items in an index partition.

<document_api>

This element shows status information related to the input API queues for the indexer.

<queue_size>

This element shows the size of the input API queues for the indexer.

<operations_processed>

This element shows the number of item batch operations processed by the indexer.

The status output follows all conventions and syntax rules that are defined for the XML file format.

The basic XML structure is as follows:

<?xml version="1.0"?>
<indexer >
  <documents />
  <column_role />
  <index_frequence />
  <partition>
    <documents />
  </partition>
  <document_api>
    <queue_size />
    <operations_processed />
  </document_api>
</indexer>


This is the top-level element. The element specifies the overall status of the indexer.

 

Attribute Description

hostname

The fully qualified domain name of the server that runs the indexer.

port

The lowest port in the range of ports that are used by the indexer.

cluster

This attribute contains information that is mainly used for debugging.

column

The index column identifier.

You can look up the column identifiers for the indexers in the deployment.xml configuration file.

row

The indexer row identifier.

You can look up the row identifiers for the indexers in the deployment.xml configuration file.

factory_type

This attribute contains information that is mainly used for debugging.

preferred_master

This attribute contains information that is mainly used for debugging.

connected_feeds

The number of active feeding (crawling) sessions that are associated with the indexer.

status

Shows the status of the indexer:

  • running ok: The indexer is running in regular operation mode.

  • reset index in progress: The indexer is re-building the content index.

    noteNote
    This is a local re-build of the content index, and does not include a re-crawl of the content.
  • indexing suspended: The indexer is suspended.

heartbeat

Shows the status of the indexer heartbeat:

  • Running: The indexer heartbeat is running.

  • Suspended: The indexer heartbeat is suspended. This may occur when the backup indexer is out of sync with the primary indexer.

The backup indexer uses the heartbeat to verify that a primary indexer is available.

exclusion_interval

This attribute contains information that is mainly used for debugging.

time_since_last_index

Shows the number of seconds since a new index set was created.

If a local re-build of the index (reset index) is in progress, you can determine the progress by looking at the status for each index partition (the status attribute for the partition sub-elements).

This element contains information about indexed items related to the indexer.

 

Attribute Description

size

Shows the total size of the pre-index item store (FiXML files), in bytes.

total

Shows the total number of items received by the indexer. This includes items that are not yet available in the search index.

indexed

Shows the total number of items that are available in the search index.

not_indexed

Shows the number of items that are received by the indexer but are not yet available in the search index.

This element specifies the role of an indexer in an index column.

 

Attribute Description

state

Shows the role of the indexer:

  • Master: The indexer is the primary indexer.

  • Backup: The indexer is the backup indexer.

  • Standalone: There is no backup indexer defined for this index column.

  • N/A: The indexer role is unknown. This state can occur immediately after a restart of the server where the indexer is running.

For more information about indexer roles, see Plan FAST Search Server farm topology (FAST Search Server 2010 for SharePoint).

backups

Shows the number of backup indexers that are associated with the indexer. Typically, there will only be one backup indexer.

This element shows the number of items indexed per second.

 

Attribute Description

min

Shows the lowest measurement of indexed items per second for the indexer. The value is reset when the indexer is restarted.

max

Shows the highest measurement of indexed items per second for the indexer. The value is reset when the indexer is restarted.

This element contains information for one index partition. The report contains one partition element for each index partition.

 

Attribute Description

id

Shows the internal index partition number.

index_id

Shows a unique string identifying the content index associated with this index partition.

status

Shows the status of an index partition:

  • idle: The index partition is in an idle state.

  • waiting: The index partition is waiting for a lower partition to finish indexing.

  • copying (x%): The index that is associated with the index partition is being copied to another server. The value in parentheses specifies the percentage of the copying that is finished.

  • indexing (x%): The index that is associated with the index partition is being re-indexed. The value in parentheses specifies the percentage of the re-indexing that is finished.

type

This attribute contains information that is mainly used for debugging.

timestamp_indexed

Shows the point in time when the index partition was last updated, specified as the number of seconds since midnight January 1, 1970 (UTC), not counting leap seconds.

indexed_per_second

Shows the average number of items indexed per second for this index partition.

pending_exclusionlist

This attribute contains information that is mainly used for debugging.

range

The indexed items are stored in a pre-index item store (FiXML files). The FIXML structures are numbered by using increasing sequence numbers. The range attribute specifies the range of FIXML structures included in the index that is associated with the index partition. If no items are indexed, the range is specified as "0-0".

Within each index column, the indexer uses a dynamic partitioning of the index to handle large number of indexed items with low indexing and query latency. This partitioning is dynamic and is handled internally on each indexer.

This element shows the number of indexed items in an index partition.

 

Attribute Description

active

Shows the number of searchable items in the index that is associated with the index partition.

total

Shows the total number of items in the index that is associated with the index partition. This includes the items in the exclusion list for the partition.

This element shows status information related to the internal input API queues for the indexer.

 

Attribute Description

number_of_elements

Shows the number of item batches stored on the internal input API queue for the indexer.

last_sequence

Shows the identifier of the last sequence operation that was processed.

frequence

Shows the number of content batch operations processed per second (average value).

load

Shows the amount of memory that is used by the input queue, as a percentage of the maximum allowed size.

status_updates

Shows the number of failed item operations registered during the uptime of the indexer server.

This element shows the size of the internal input API queues for the indexer.

 

Attribute Description

current

Shows the size of the input queue in bytes.

This element shows the number of item batch operations processed by the indexer.

 

Attribute Description

api

Shows the number of item batch operations processed during the uptime of the indexer server.
