Infrastructure Metrics Streaming

Created:  | Updated: 


z/IRIS transformed RMF SMF records into metrics and streams them to a target metrics database which could be a time-series database or an enterprise observability.


Supported RMF SMF records

SMF Type

Record description

70

Processor Activity

Measurements

Measurements are prefixed. These prefixes can be changed via the z/IRIS IronTap server or container configuration.

Tags,labels and fields provide indexing, filtering and grouping of metrics.

CPU load

zos.rmf.cpu.mvs.utilization

Utilization is computed as a percentage of online time:

percentage_lpar_busy_time = (online_time - (wait_time + parked_time) /
(online_time - parked_time) x 100

SMF70TYP

gauge

field

The percentage of the online time that the logical processor was busy.

zos.rmf.cpu.mvs.lpar.utilization

LPAR utilization is computed as a percentage of dispatched logical core time.
When LOADxx PROCVIEW CORE is in effect:

percentage_lpar_busy_time = (multithreading_core_time) / online_time x 100

Otherwise:

percentage_lpar_busy_time = (online_time - wait_time) / online_time x 100
