Class
Description
This class delegates to either javax.xml.bind.DatatypeConverter (for Java < 8) or java.util.Base64 (Java 8+)
to perform Base64 encoding of a String.
Exports metrics about JVM buffers.
Collect metrics from Caffeine's com.github.benmanes.caffeine.cache.Cache.
Collect metrics from Guava's com.google.common.cache.Cache.
Algorithm solving the "Targeted Quantile Problem" as described in
"Effective Computation of Biased Quantiles over Data Streams"
by Cormode, Korn, Muthukrishnan, and Srivastava.
Exports metrics about JVM classloading.
A collector for a set of metrics.
A metric, and all of its samples.
A single Sample, with a unique name and set of labels.
A registry of Collectors.
Counter metric, to track counts of events or running totals.
The value of a single Counter.
Exemplar sampler for counter metrics.
Counter metric family, for custom collectors and exporters.
Default Exemplar sampler.
Registers the default Hotspot collectors.
One or more variables that together maintain an initially zero
double sum.Enumeration metric, to track which of a set of states something is in.
The value of a single Enumeration.
Immutable data class holding an Exemplar.
Static configuration for Exemplar behavior.
For convenience, an interface for implementing both,
the
CounterExemplarSampler and the HistogramExemplarSampler.The MetricsServlet class exists to provide a simple way of exposing the metrics values.
Filter implements the common functionality provided by the two MetricsFilter implementations:
javax version:
io.prometheus.client.filter.MetricsFilter provided by simpleclient_servlet
jakarta version: io.prometheus.client.servlet.jakarta.filter.MetricsFilter provided by simpleclient_servlet_jakarta
Thrown when there is a misconfiguration in
web.xml.Exports metrics about JVM garbage collectors.
Gauge metric, to report instantaneous values.
The value of a single Gauge.
Represents an event being timed.
Gauge metric family, for custom collectors and exporters.
Export metrics in the Graphite plaintext format.
Histogram metric, to track distributions of events.
The value of a single Histogram.
Represents an event being timed.
Exemplar sampler for histogram metrics.
Expose Prometheus metrics using a plain Java HttpServer.
We keep the original constructors of
HTTPServer for compatibility, but new configuration
parameters like sampleNameFilter must be configured using the Builder.Handles Metrics collections from the given registry.
Info metric, key-value pairs.
The value of a single Info.
Log4j2 log statements at various log levels
Collect metrics from jetty's org.eclipse.jetty.server.handler.StatisticsHandler.
Exports metrics about JVM memory areas.
The MetricsFilter class provides a high-level filter that enables tunable collection of metrics for Servlet
performance.
The MetricsFilter class provides a high-level filter that enables tunable collection of metrics for Servlet
performance.
The MetricsServlet class provides a simple way of exposing the metrics values.
The MetricsServlet class provides a simple way of exposing the metrics values.
Replacement for Java 8's
java.util.function.Predicate for compatibility with Java versions < 8.Export metrics via the Prometheus Pushgateway.
Filter samples (i.e.
For convenience, an implementation of a
Supplier<Predicate<String>> that
always returns the same sampleNameFilter.Builders let you configure and then create collectors.
SimpleTimer, to measure elapsed duration in seconds as a double.
Exports the standard exports common across all prometheus clients.
A package-local class holding common representation and mechanics
for classes supporting dynamic striping on 64bit values.
Padded variant of AtomicLong supporting only raw accesses plus CAS.
The value of a single Summary.
Represents an event being timed.
Summary metric family, for custom collectors and exporters.
Replacement for Java 8's
java.util.function.Supplier for compatibility with Java versions < 8.Exports metrics about JVM thread areas.
Wrapper around CKMSQuantiles.
Exports JVM version info.
