This chapter illustrates how to run plug-in test cases and store test results into community’s InfluxDB. The framework is shown in Framework.
As shown in Framework, there are two ways to store Storperf test results into community’s InfluxDB:
Our plan is to support rest-api in D release so that other testing projects can call the rest-api to use yardstick dispatcher service to push data to Yardstick’s InfluxDB database.
For now, InfluxDB only supports line protocol, and the json protocol is deprecated.
Take ping test case for example, the raw_result
is json format like this:
"benchmark": {
"timestamp": 1470315409.868095,
"errors": "",
"data": {
"rtt": {
"ares": 1.125
}
},
"sequence": 1
},
"runner_id": 2625
}
With the help of “influxdb_line_protocol”, the json is transform to like below as a line string:
'ping,deploy_scenario=unknown,host=athena.demo,installer=unknown,pod_name=unknown,
runner_id=2625,scenarios=Ping,target=ares.demo,task_id=77755f38-1f6a-4667-a7f3-
301c99963656,version=unknown rtt.ares=1.125 1470315409868094976'
So, for data output of json format, you just need to transform json into line format and call influxdb api to post the data into the database. All this function has been implemented in Influxdb. If you need support on this, please contact Mingjiang.
curl -i -XPOST 'http://104.197.68.199:8086/write?db=yardstick' --
data-binary 'ping,deploy_scenario=unknown,host=athena.demo,installer=unknown, ...'
Grafana will be used for visualizing the collected test data, which is shown in Visual. Grafana can be accessed by Login.
