Example 3 with Measure

use of io.opencensus.stats.Measure in project instrumentation-java by census-instrumentation.

the class StatszZPageHandler method groupViewsByDirectoriesAndGetMeasures.

// Parses view names, creates a tree that represents the directory structure and put each view
// under appropriate directory. Also gets measures from the given views.
// Directories are the namespaces in view name, separated by '/'.

            if (node == null) {
                // Should never happen. Work around the nullness checker.
                break;
            }
            String dir = dirs.get(i);
            if ("".equals(dir) && i == 0) {

                continue;
            }
            node.views++;
            if (i != dirs.size() - 1) {
                // Non-leaf node (directory node)
                node.children.putIfAbsent(dir, new TreeNode());
                node = node.children.get(dir);
            } else {
                // Leaf node (view node)
                node.children.putIfAbsent(dir, new TreeNode(view.getName()));
            }
        }
        Measure measure = view.getMeasure();
        measures.putIfAbsent(measure.getName(), measure);
    }
}

    Iterator<Measurement> iterator = stats.iterator();
    Map<String, AttachmentValue> attachments = stats.getAttachments();

        Measurement measurement = iterator.next();
        Measure measure = measurement.getMeasure();
        if (!measure.equals(registeredMeasures.get(measure.getName()))) {
            // unregistered measures will be ignored.
            continue;
        }
        Collection<MutableViewData> viewDataCollection = mutableMap.get(measure.getName());
        for (MutableViewData viewData : viewDataCollection) {
