The calculation collector is named: /DVD/MON_CA_CL_COL_CALC
Collector collects KPIs with defined calculation function of input table. The KPIs are defined via KPI definition and input table /DVD/MON_CA_KDEF.
Input table /DVD/MON_CA_KDEF sets up calculation function for KPI. Input table has following fields:
KPI name | Same technical name like in KPI definition |
Function | Calculation function |
Changed by | Last change by user [automatically filled] |
Changed at | Last change date and time [automatically filled] |
Created by | Created by user [automatically filled] |
Created at | Created date and time [automatically filled] |
Functions for calculations
KPI() – Function KPI() returns collected values of KPI in time range.
Parameters: only one KPI
AVG() – Calculates average of values.
MAX() – Selects the maximum value.
MIN() – Selects the minimum value.
SUM() – Function sum all values.
DIFF() – Function subtract all values.
MUL() – Multiplication of all values.
DIV() – Dividing of all values.
Parameters for functions above:
- only one KPI
- more constant values
- more functions
- combination of constants and functions
Examples
KPI(DB_CPU_LOAD5_P) – returns all values in time range
MAX(KPI(DB_CPU_LOAD5_P)) – gets maximum of values from KPI
MAX(MAX(KPI(DB_CPU_LOAD5_P)), 60) – gets maximum of two values,
- first parameter is MAX(KPI(DB_CPU_LOAD5_P))
- and second is threshold – 60
DIV(MAX(MAX(KPI(DB_CPU_LOAD5_P)), 60), 60) – divides maximum from
- function MAX(MAX(KPI(DB_CPU_LOAD5_P)), 60)
- and threshold – 60
Example of input table
KPI name | Function |
CF_THRESHOLD | DIV(MAX(MAX(KPI(DB_CPU_LOAD5_P)), 90), 90) |
ZCALC_FUNCTION | MAX(KPI(CPU_IDLE)) |
Some KPIs are provided in standard delivery with collector as examples:
KPI name | Description | Unit |
CF_THRESHOLD | Value relative to threshold of KPI | count |
Step by step to define KPI:
- Create KPI definition
- Define function in input table
