Query Query: 0E2EREP_IS_GARBAGE_OVERVIEW_HR

 

This query is used in interactive reporting in the Technical Monitoring work center. The report displays the following metrics for Garbage Collection (GC):

  • The report shows the proportion of all garbage collections in the total runtime of the Java processes, both the mean value in the displayed period, and the maximum hourly mean value within the period. The mean value should not be more than 5% of the total runtime.

  • The proportion of full garbage collections is displayed. This value should be under 5%.

Maximum GC

‘Key value’ [1KYFNM] = ‘Maximum’ [0SMD_MAX]

‘Key value name’ [0SMD_MENA] = % GC TIME (LAST 5 MINUTES)

Mean GC

‘Key value’ [1KYFNM] = ‘Mean’ [0SMD_MPEH_XPI_CK001]

‘Key value name’ [0SMD_MENA] = % GC TIME (LAST 5 MINUTES)

Proportion of Full GC

‘Key value’ [1KYFNM] = ‘Mean’ [0SMD_MPEH_XPI_CK001]

‘Key figure name’ [0SMD_MENA] = FULLGC FRACTION (%)

Graphic Norming: Up to 5% GC is normal
