This repository contains a series of integrations for Prometheus4Cats that instrument other libraries or metric sources. Each integration is documented below:
Google Bigtable Java client instrumentation. Uses a Prometheus4Cats callback registry to inspect the client metrics registered with OpenCensus.
Use the BigtableOpenCensusMetrics
smart constructor to enable metric collection on the Java client and registering them with a
MetricFactory.WithCallbacks.
"com.permutive" %% "prometheus4cats-contrib-google-cloud-bigtable" % "4.2.0"Cats-Effect metrics taken from JMX MBeans. This includes a CPU starvation counter.
Use the CatsEffectMBeans
smart constructor register callbacks for Cats-Effect MBeans with MetricFactory.WithCallbacks.
"com.permutive" %% "prometheus4cats-contrib-cats-effect" % "4.2.0"FS2-Kafka integration that instruments consumers and producers. Uses a Prometheus4Cats callback registry to inspect built-in Kafka client metrics.
Use the smart constructors in KafkaMetrics
to register callbacks for producers and consumers with a MetricFactory.WithCallbacks.
"com.permutive" %% "prometheus4cats-contrib-fs2-kafka" % "4.2.0"Instrumented implementation of Refreshable. Provides the following metrics:
| Metric Name | Labels | Metric Type | Description |
|---|---|---|---|
refreshable_read_total |
refreshable_name, value_state |
Counter | Number of times this Refreshable has been read, with a label denoting the state of the value |
refreshable_is_running |
refreshable_name |
Gauge | Whether this Refreshable is running - 1 if true, 0 if false |
refreshable_retries_exhausted |
refreshable_name |
Gauge | Whether retries have been exhausted for this Refreshable - 1 if true, 0 if false |
refreshable_refresh_failing |
refreshable_name |
Gauge | Whether refresh is currently failing - 1 if true, 0 if false |
refreeshable_refresh_success_total |
refreshable_name |
Counter | Number of times the refresh operation has succeeded |
refreshable_refresh_failure_total |
refreshable_name |
Counter | Number of times refresh failed |
refreshable_status |
refreshable_name, value_state |
Gauge | The current status of this Refreshable - a value of 1 against the label value indicates the current state |
Use the InstrumentedRefreshable
smart constructor to instrument a given Refreshable when used with an instance of MetricFactory.WithCallbacks.
"com.permutive" %% "prometheus4cats-contrib-refreshable" % "4.2.0"Instrumented implementations of Trace4Cats interfaces. Provides the following metrics:
| Interface | Metric Name | Labels | Metric Type | Description |
|---|---|---|---|---|
EntryPoint |
trace4cats_entry_point_spans_total |
span_kind, is_root, sample_decision |
Counter | Total number of spans created |
SpanCompleter |
trace4cats_completer_spans_total |
completer_name |
Counter | Total number of spans completed |
SpanCompleter |
trace4cats_completer_complete_time |
completer_name |
Histogram | Time it takes to complete a span in seconds |
SpanExporter |
trace4cats_exporter_batches_total |
exporter_name |
Counter | Total number of batches sent via this exporter |
SpanExporter |
trace4cats_exporter_export_time |
exporter_name |
Histogram | Time it takes to export a span batch in seconds |
SpanExporter |
trace4cats_exporter_batch_size |
exporter_name |
Histogram | Size distribution of batches sent by this exporter |
Use the InstrumentedEntrypoint,
InstrumentedSpanCompleter and
InstrumentedSpanExporter with
a MetricFactory to return instrumented wrappers of the underlying implementations.
