External Location Indices Consistency Test

The index server indexes and classifies documents and answers search queries. These indexes are stored in the relevant directories. If the location of the directories are altered, then the SAP TREX engine server may not be able to retrieve the indexes available in those directories. This in turn, may affect the search capabilities of the SAP TREX search engine server. Therefore, it is necessary to keep a constant vigil on the number of indexes that are present in the location that is other than the default directory. The External Location Indices Inconsistency test helps administrators in this regard.

This test monitors the number of indexes that were available in a location other than the location of the default directory. In addition, this test reports the total number of indexes in the directory and the indexes that are valid.

Target of the test : A SAP TREX

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the SAP TREX server that is to be monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed


The host for which the test is to be configured.


Specify the port at which the specified host listens. By default, this is 30001.

TREX Directory

Specify the full path to the SAP TREX instance that is to be monitored for e.g., the location can be specified as D:\usr\sap\TRX\TRX01.


Specify the duration (in seconds) beyond which this test should time out in the Timeout text box. The default is 120 seconds.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measures made by the test
Measurement Description Measurement Unit Interpretation

Inconsistent indices

Indicates the number of indexes that were inconsistent i.e., stored in a different base path location as against the location where the data resides.


If the indexes are corrupted/inconsistent, then the indexes should be recreated in order to be accessed. Therefore, if too many indexes are corrupted/inconsistent, then the performance of the TREX server would be affected.

The detailed diagnosis of this measure lists the name of the indexes that were inconsistent, the namespace corresponding to the indexes etc.

Valid indices

Indicates the number of indexes with the correct base path and namespace location.


A high value is desired for this measure.

Total indices

Indicates the total number of indexes stored on the disk.
