URL: https://github.com/apache/skywalking/issues/5417#issuecomment-684186240
the bug is in the MetricsQuery*DAO , it read the value as long, but the
actually value is double like 0.8842238771569793 for example, code as below
```
// Label is null, because in readMetricsValues, no label parameter.
IntValues intValues = metricsValues.getValues();
for (String id : ids) {
KVInt kvInt = new KVInt();
kvInt.setId(id);
kvInt.setValue(0);
if (idMap.containsKey(id)) {
Map<String, Object> source = idMap.get(id);
kvInt.setValue(((Number)
source.getOrDefault(valueColumnName, 0)).longValue());
} else {
kvInt.setValue(ValueColumnMetadata.INSTANCE.getDefaultValue(condition.getName()));
}
intValues.addKVInt(kvInt);
}
```
@wu-sheng , Can I submit a pr and fix this ?
