Example 6 with GaugeMetricFamily

use of io.prometheus.client.GaugeMetricFamily in project FredBoat by Frederikam.

the class ThreadPoolCollector method collect.

@Override
public List<MetricFamilySamples> collect() {
    List<MetricFamilySamples> mfs = new ArrayList<>();
    List<String> labelNames = Collections.singletonList("name");
    GaugeMetricFamily activeThreads = new GaugeMetricFamily("fredboat_threadpool_active_threads_current", "Amount of active threads in a thread pool", labelNames);
    mfs.add(activeThreads);
    GaugeMetricFamily queueSize = new GaugeMetricFamily("fredboat_threadpool_queue_size_current", "Size of queue of a thread pool (including scheduled tasks)", labelNames);
    mfs.add(queueSize);
    CounterMetricFamily completedTasks = new CounterMetricFamily("fredboat_threadpool_completed_tasks_total", "Total completed tasks by a thread pool", labelNames);
    mfs.add(completedTasks);
    for (Map.Entry<String, ThreadPoolExecutor> entry : pools.entrySet()) {
        String poolName = entry.getKey();
        ThreadPoolExecutor pool = entry.getValue();
        List<String> labels = Collections.singletonList(poolName);
        activeThreads.addMetric(labels, pool.getActiveCount());
        queueSize.addMetric(labels, pool.getQueue().size());
        // guaranteed to always increase, ergo good fit for a counter
        completedTasks.addMetric(labels, pool.getCompletedTaskCount());
