eG Monitoring
 

Measures reported by EgTabIdxInfoTest

An index is an alphabetical listing of the terms found on database records and the number of records on which the terms are found. Indexes support the efficient processing of requests to the database. If an appropriate index exists for a table, the database can use the index to limit the number of records it must inspect. Without indexes, database must perform a scan, i.e. scan every row in the database tables, to respond to the request. These scans are time-consuming, resource-intensive operations, which if not contained, can degrade performance of the database. To avoid these extensive scans, each table in the database should be indexed. This is where the eG Database EgTabIdxInfoTest helps.  

This test reports whether the auto-indexing is currently enabled for the eG database and reveals the statistics related to auto indexing of the database.

Outputs of the test : One set of results for the eG manager being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Enabled Indicates whether/not the auto indexing is enabled for the eG database.   The numeric values that correspond to the measure values are as follows:

Measure Value Numeric Value
Yes 1
No 0
Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not auto indexing has run today. The graph of this measure however, represents the same using the numeric equivalents only.
Frequency Indicates how often the auto index should be rebuilt. Days  
Rebuild_time Indicates the maximum time duration set for performing auto indexing. Hours  
Sec_idx_only Indicates the number of secondary indexes that should be rebuilt. Number  
Total_idx_available Indicates the total number of indexes available. Number  
Pk_idx_available Indicates the number of primary key indexes available in the eG database. Number  
Idx_available Indicates the number of idx indexes available in the eG database. Number  
Others_available Indicates the total number of tables available in the eG database. Number  
Status Indicates the current status of auto indexing.   The numeric values that correspond to the current status of auto indexing are as follows:

Measure Value Numeric Value
Yes 1
No 0
Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not cleanup has run today. The graph of this measure however, represents the same using the numeric equivalents only.

Completed_idx Indicates the total number of indexes that are rebuilt. Number  
Completed_pk_idx Indicates the number of primary key indexes that are rebuilt. Number  
Completed_idx_idx Indicates the number of idx indexes that are rebuilt. Number  
Completed_other_idx Indicates the number of other indexes that are rebuilt. Number  
Failed_idx Indicates how many times that the auto indexing failed. Number  
Duration Indicates the time taken for auto indexing. Minutes A very high value for this measure could indicate issues auto indexing process.
Run_today Indicates whether auto indexing has run today or not.   The numeric values that correspond to the current status of auto indexing are as follows:

Measure Value Numeric Value
Yes 1
No 0
Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not auto indexing has run today. The graph of this measure however, represents the same using the numeric equivalents only.
Time_since Indicates the elapsed time duration since the last auto indexing process.   With the help of this measure, you can quickly detect whether a scheduled auto indexing occurred on the eG database or not.
