Description

Chinmay found the following issue

When settings a DimensionsScheme App Data Tracker doesn't pickup the timebuckets or aggregators. The DimensionsScheme is as follows

public static class IngestionDimensionsSchema implements AutoMetric.DimensionsScheme, Serializable
{
private static final long serialVersionUID = 20150910103301L;

public String[] getTimeBuckets()
{
return new String[]

{"1s", "1m"}

;
}

public String[] getDimensionAggregationsFor(String logicalMetricName)
{
return new String[]

{"LAST"}

;
}
}

And then dag.setAttribute(tracker, Context.OperatorContext.METRICS_DIMENSIONS_SCHEME, new IngestionDimensionsSchema());

I saw that the Schema being sent out was as follows

"data":{
"type":"metricsSchema",
"version":"1.0",
"appUser":"chinmay",
"appName":"Ingestion",
"logicalOperatorName":"Tracker",
"values":[

{ "name":"eventCounts", "type":"long", "dimensionAggregators":"[Ljava.lang.String;@1b12a6b8" }

],
"timeBuckets":"[Ljava.lang.String;@657f87ea"

Chinmay saw in AppDataPushAgent line 271

String[] timeBuckets = metricAggregatorMeta.getTimeBuckets();
if (timeBuckets != null)

{ result.put("timeBuckets", timeBuckets); }

result is a JSONObject... It should have created a JSONArray of it and then done result.put
