Chapter 6. Examples of using metering
Use the following example Reports to get started measuring capacity, usage, and utilization in your cluster. These examples showcase the various types of reports metering offers, along with a selection of the predefined queries.
Prerequisites
- Install Metering
- Review the details about writing and viewing reports.
6.1. Measure cluster capacity hourly and daily
The following Report demonstrates how to measure cluster capacity both hourly and daily. The daily Report works by aggregating the hourly Report’s results.
The following report measures cluster CPU capacity every hour.
Hourly CPU capacity by cluster example
apiVersion: metering.openshift.io/v1
kind: Report
metadata:
name: cluster-cpu-capacity-hourly
spec:
query: "cluster-cpu-capacity"
schedule:
period: "hourly" 1
- 1
- You could change this period to
dailyto get a daily report, but with larger data sets it is more efficient to use an hourly report, then aggregate your hourly data into a daily report.
The following report aggregates the hourly data into a daily report.
Daily CPU capacity by cluster example
apiVersion: metering.openshift.io/v1 kind: Report metadata: name: cluster-cpu-capacity-daily 1 spec: query: "cluster-cpu-capacity" 2 inputs: 3 - name: ClusterCpuCapacityReportName value: cluster-cpu-capacity-hourly schedule: period: "daily"
- 1
- To stay organized, remember to change the name of your Report if you change any of the other values.
- 2
- You can also measure
cluster-memory-capacity. Remember to update the query in the associated hourly report as well. - 3
- The
inputssection configures this report to aggregate the hourly report. Specifically,value: cluster-cpu-capacity-hourlyis the name of the hourly report that gets aggregated.
6.2. Measure cluster usage with a one-time Report
The following Reports to measure cluster usage from a specific starting date forward. The Report only runs once, after you save it and apply it.
CPU usage by cluster example
apiVersion: metering.openshift.io/v1 kind: Report metadata: name: cluster-cpu-usage-2019 1 spec: reportingStart: '2019-01-01T00:00:00Z' 2 reportingEnd: '2019-12-30T23:59:59Z' query: cluster-cpu-usage 3 runImmediately: true 4
- 1
- To stay organized, remember to change the name of your Report if you change any of the other values.
- 2
- Configures the Reports to start using data from the
reportingStarttimestamp until thereportingEndtimestamp. - 3
- Adjust your query here. You can also measure cluster usage with the
cluster-memory-usagequery. - 4
- This tells the Report to run immediately after saving it and applying it.
6.3. Measure cluster utilization using cron expressions
You can also use cron expressions when configuring the period of your reports. The following report measures cluster utilization by looking at CPU utilization from 9am-5pm every weekday.
Weekday CPU utilization by cluster example
apiVersion: metering.openshift.io/v1 kind: Report metadata: name: cluster-cpu-utilization-weekdays 1 spec: query: "cluster-cpu-utilization" 2 schedule: period: "cron" expression: 0 0 * * 1-5 3
