7 Binding Support Function Metrics

BSF Metrics

This chapter includes information about Metrics for Oracle Communications Cloud Native Core, Binding Support Function (BSF).

BSF uses the observability tool Grafana to analyze and visualize data. The Grafana Dashboard consists of panels displaying the data as graphs, charts or other visualizations. A dashboard in Grafana is represented by a JSON object, which stores the metadata of its dashboard. Following Grafana dashboards are created for BSF Observability and debugging purposes:
  • Observability Dashboard:
    • This dashboard metadata is stored in the BSF_Observability_Dashboard.json file.
    • This dashboard has the panels that monitors the overall health status of the setup & contains details like resource utilization, kmps, latency, etc.
    • Customers can use this Dashboard on a regular basis for observing the status of the setup and also for assessing the setup performance with a run.
    • Depending upon the applicability of a panel or row, the customers have the flexibility to either remove, update or add content to the Dashboard.
  • Debug Dashboard:
    • This dashboard metadata is stored in the BSF_Debug_Dashboard.json file.
    • This dashboard has the panels that monitor the operational status of the setup and is used for debugging & troubleshooting purposes.
    • Customers can use this Dashboard when any issue occur in the NF and also when reporting a probable issue to Oracle Customer Support from the setup.
    • Depending upon the applicability of a panel or row, the customers have the flexibility to either remove, update or add content to the Dashboard.

The name of the metrics may contain suffix such as total, seconds, max and so on. It gets added by the Micrometer registry if it is not present in the metrics name. The metric name has the following format for suffix:

The metric name is equal to <Basename of the metric>_<Suffix>

Table 7-1 Metrics type and Suffix

Metric Type Suffix
Counter _total
Gauge N/A
TimerGauge _seconds
MultiGauge N/A
Timer _seconds_max or _seconds

Note: There are two types of suffix used for timer metrics.

For example, my_timer_seconds_max gauge and my_timer_seconds summary. In summary type, there will be further addition of suffix such as _count or _sum.
DistributionSummary N/A or _max

Note: There are two types of suffix used for DistributionSummary.

For example, my_distribution_ratio histogram and my_distribution_ratio_max gauge. In the histogram type there will be further addition of suffix such as bucket, _count, or sum.
LongTaskTimer _seconds_max or _seconds

Note: There are two types of suffix used for LongTaskTimer.

For example, long_task_timer_seconds_max gauge and long_task_timer_seconds summary. In summary type there will be further addition of suffix such as _active_count or _duration_sum.
