OpenTelemetry system metrics Instrumentation

Instrument to report system (CPU, memory, network) and process (CPU, memory, garbage collection) metrics. By default, the following metrics are configured:

{
    "system.cpu.time": ["idle", "user", "system", "irq"],
    "system.cpu.utilization": ["idle", "user", "system", "irq"],
    "system.memory.usage": ["used", "free", "cached"],
    "system.memory.utilization": ["used", "free", "cached"],
    "system.swap.usage": ["used", "free"],
    "system.swap.utilization": ["used", "free"],
    "system.disk.io": ["read", "write"],
    "system.disk.operations": ["read", "write"],
    "system.disk.time": ["read", "write"],
    "system.network.dropped.packets": ["transmit", "receive"],
    "system.network.packets": ["transmit", "receive"],
    "system.network.errors": ["transmit", "receive"],
    "system.network.io": ["transmit", "receive"],
    "system.network.connections": ["family", "type"],
    "system.thread_count": None
    "process.runtime.memory": ["rss", "vms"],
    "process.runtime.cpu.time": ["user", "system"],
    "process.runtime.gc_count": None,
    "process.runtime.thread_count": None,
    "process.runtime.cpu.utilization": None,
    "process.runtime.context_switches": ["involuntary", "voluntary"],
}

Usage

from opentelemetry.metrics import set_meter_provider
from opentelemetry.instrumentation.system_metrics import SystemMetricsInstrumentor
from opentelemetry.sdk.metrics import MeterProvider
from opentelemetry.sdk.metrics.export import ConsoleMetricExporter, PeriodicExportingMetricReader

exporter = ConsoleMetricExporter()

set_meter_provider(MeterProvider([PeriodicExportingMetricReader(exporter)]))
SystemMetricsInstrumentor().instrument()

# metrics are collected asynchronously
input("...")

# to configure custom metrics
configuration = {
    "system.memory.usage": ["used", "free", "cached"],
    "system.cpu.time": ["idle", "user", "system", "irq"],
    "system.network.io": ["transmit", "receive"],
    "process.runtime.memory": ["rss", "vms"],
    "process.runtime.cpu.time": ["user", "system"],
    "process.runtime.context_switches": ["involuntary", "voluntary"],
}
SystemMetricsInstrumentor(config=configuration).instrument()

API

class opentelemetry.instrumentation.system_metrics.SystemMetricsInstrumentor(labels=None, config=None)

Bases: BaseInstrumentor

instrumentation_dependencies()

Return a list of python packages with versions that the will be instrumented.

The format should be the same as used in requirements.txt or pyproject.toml.

For example, if an instrumentation instruments requests 1.x, this method should look like: :rtype: Collection[str]

def instrumentation_dependencies(self) -> Collection[str]:

return [‘requests ~= 1.0’]

This will ensure that the instrumentation will only be used when the specified library is present in the environment.
