The green power save history API provides support for obtaining data related to the switch CPU.
Green power save history OpEN API
This document provides a brief description of the green power save history OpEN APIs. The APIs provide the following services:
- Get maximum number of intervals tracked for CPU utilization.
- Get an array of CPU utilization values, one per tracked period.
All 'Set' operations may affect the switch behavior and configuration.
Example C Application green_pwr_sav_history_example
Initialization
In the main function, the sample application initializes the OpEN API RPC service by calling openapiClientRegister() and waits for the RPC service in switchdrvr to start. A Client Handle is returned by openapiClientRegister() which is used while invoking the OpEN APIs. The application then exercises the associated OpEN APIs and logs informational and/or error messages on the console. The example application runs to its completion and exits.
green_pwr_sav_history_example
green_pwr_sav_history_example.c is a sample application that demonstrates the use of the Green power save history OpEN APIs. It is started from the command line and has the following usage:
Usage: green_pwr_sav_history_example <test#> <arg1> <arg2> ...
- Test 1: testGreenEthrEeeLpiHistoryIntfSampleIntervalSet: green_pwr_sav_history_example 1 <interval>
- Test 2: testGreenEthrEeeLpiHistoryIntfSampleIntervalGet: green_pwr_sav_history_example 2
- Test 3: testGreenEthrEeeLpiHistoryIntfMaxSamplesSet: green_pwr_sav_history_example 3 <samples>
