Measures reported by MongoCallsTest

The first step to ensuring an above-par experience for MongoDB users is to be able to spot failures, well before the users notice them and complain! This is exactly what the Mongo Calls test helps administrators achieve! This test monitors queries/calls to the tables in MongoDB, and rapidly alerts administrators to failed table operations. Additionally, the test also points to the type of table operations that experienced maximum failures - is it create table? alter table? drop table? rename table? compact table? salvage table? truncate table? or verify table?

Outputs of the test: One set of results for the MongoDB server monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_table_calls Indicates the number of calls made to tables in MongoDB during the last measurement period. Number

 
Total_succes_table_calls Indicates the number of table calls that were successful during the last measurement period. Number

Ideally, the value of this measure should be equal to the value of the Total calls measure.
Total_failed_table_calls Indicates the number of table calls that failed during the last measurement period. Number

Ideally, the value of this measure should be 0 or very low.
percent_of_failed_calls Indicates the percentage of table calls that failed during the last measurement period. Percent

A value close to 100% implies that almost all table calls are failing. This warrants an investigation.
Table_alter_succes_calls Indicates the number of table alter calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_alter_failed_calls Indicates the number of table alter calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_alter_unchng_skip Indicates the number of table alter unchanged and skipped calls that were made during the last measurement period. Number

 
Table_compact_successful Indicates the number of table compact calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_compact_failed_cal Indicates the number of table alter calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_crte_succes_calls Indicates the number of table create calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_crte_failed_calls Indicates the number of table create calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_drop_succes_calls Indicates the number of table drop calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_drop_failed_calls Indicates the number of table drop calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_renme_succes_calls Indicates the number of table rename calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_renme_failed_calls Indicates the number of table rename calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_salvge_succes_cals Indicates the number of table salvage calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_salvge_failed_cals Indicates the number of table salvage calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_trncte_succes_cals Indicates the number of table truncate calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_trncte_failed_cals Indicates the number of table truncate calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
Table_verify_succes_cals Indicates the number of table verify calls that were successful during the last measurement period. Number

A high value is desired for this measure.
Table_verify_failed_call Indicates the number of table verify calls that failed during the last measurement period. Number

The value 0 or a low value is desired for this measure.
