SolarManager unter Versionsverwaltung
Erster Stand der Hintergrundprozesse, die auf der Synology unter /volume1/homes/wagner/SolarManager laufen: der Manager selbst, die Sammler je Geraet, die MQTT-Bruecke, der Wecker und - neu hinzugezogen - der AutoAction-Runner, der als Hintergrundprozess hierher gehoert und nicht ins Web-Verzeichnis. Zugangsdaten stehen nicht mehr im Quelltext, sondern in config.ini, die nicht mit eingecheckt wird. Vorlage ist config.ini.example, gelesen wird sie von konfig.py. Betroffen waren solarManager.py (Datenbank und Wattpilot), zeit.py, gatherWaterData.py, wecker.py und skoda_testdaten.py, das sich das Passwort bisher aus dem Quelltext eines anderen Moduls herausgesucht hat. Die Kia-Anbindung ist mit dem Fahrzeug entfallen: kiaTest.py, gatherCarData.py und hyundai_kia_connect_api sind nicht mehr dabei, ebenso gatherInverterData.py, auf das nur noch eine auskommentierte Zeile zeigte. Die mitgelieferten Bibliotheken bleiben im Repository - die NAS hat kein pip, sie muessen neben den Skripten liegen. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Global Error Handler
|
||||
|
||||
This module provides a global error handler and an interface that allows
|
||||
error handlers to be registered with the global error handler via entry points.
|
||||
A default error handler is also provided.
|
||||
|
||||
To use this feature, users can create an error handler that is registered
|
||||
using the ``opentelemetry_error_handler`` entry point. A class is to be
|
||||
registered in this entry point, this class must inherit from the
|
||||
``opentelemetry.sdk.error_handler.ErrorHandler`` class and implement the
|
||||
corresponding ``handle`` method. This method will receive the exception object
|
||||
that is to be handled. The error handler class should also inherit from the
|
||||
exception classes it wants to handle. For example, this would be an error
|
||||
handler that handles ``ZeroDivisionError``:
|
||||
|
||||
.. code:: python
|
||||
|
||||
from opentelemetry.sdk.error_handler import ErrorHandler
|
||||
from logging import getLogger
|
||||
|
||||
logger = getLogger(__name__)
|
||||
|
||||
|
||||
class ErrorHandler0(ErrorHandler, ZeroDivisionError):
|
||||
|
||||
def _handle(self, error: Exception, *args, **kwargs):
|
||||
|
||||
logger.exception("ErrorHandler0 handling a ZeroDivisionError")
|
||||
|
||||
To use the global error handler, just instantiate it as a context manager where
|
||||
you want exceptions to be handled:
|
||||
|
||||
|
||||
.. code:: python
|
||||
|
||||
from opentelemetry.sdk.error_handler import GlobalErrorHandler
|
||||
|
||||
with GlobalErrorHandler():
|
||||
1 / 0
|
||||
|
||||
If the class of the exception raised in the scope of the ``GlobalErrorHandler``
|
||||
object is not parent of any registered error handler, then the default error
|
||||
handler will handle the exception. This default error handler will only log the
|
||||
exception to standard logging, the exception won't be raised any further.

purposes:

1. Match instruments: When an instrument matches a view, measurements

received by that instrument will be processed.
|
||||
2. Customize metric streams: A metric stream is identified by a match
|
||||
between a view and an instrument and a set of attributes. The metric
|
||||
stream can be customized by certain attributes of the corresponding view.
|
||||
|
||||
The attributes documented next serve one of the previous two purposes.

instrument must be to match the view.

|

instrument must have to match the view. Wild card characters are supported. Wild
|
||||
card characters should not be used with this attribute if the view has also a
|
||||
``name`` defined.

meter_name: This is an instrument matching attribute: the name the

the instrument meter must have to match the view.

|

URL the instrument meter must have to match the view.

name: This is a metric stream customizing attribute: the name of the

metric stream. If `None`, the name of the instrument will be used.

description: This is a metric stream customizing attribute: the
|

description of the metric stream. If `None`, the description of the instrument will

be used.

attribute_keys: This is a metric stream customizing attribute: this is
|
||||
a set of attribute keys. If not `None` then only the measurement attributes that
|
||||
are in ``attribute_keys`` will be used to identify the metric stream.
|
||||
|
||||
aggregation: This is a metric stream customizing attribute: the
|
||||
aggregation instance to use when data is aggregated for the
|

corresponding metrics stream. If `None` an instance of

`DefaultAggregation` will be used.

This package implements `OpenTelemetry Resources
|
||||
<https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/sdk.md#resource-sdk>`_:
|
||||
|
||||
*A Resource is an immutable representation of the entity producing
|
||||
telemetry. For example, a process producing telemetry that is running in
|
||||
a container on Kubernetes has a Pod name, it is in a namespace and
|
||||
possibly is part of a Deployment which also has a name. All three of
|
||||
these attributes can be included in the Resource.*
|
||||
|
||||
Resource objects are created with `Resource.create`, which accepts attributes
|
||||
(key-values). Resources should NOT be created via constructor, and working with
|
||||
`Resource` objects should only be done via the Resource API methods. Resource
|
||||
attributes can also be passed at process invocation in the
|
||||
:envvar:`OTEL_RESOURCE_ATTRIBUTES` environment variable. You should register
|
||||
your resource with the `mysql.opentelemetry.sdk.trace.TracerProvider` by passing
|
||||
them into their constructors. The `Resource` passed to a provider is available
|
||||
to the exporter, which can send on this information as it sees fit.
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
trace.set_tracer_provider(
|
||||
TracerProvider(
|
||||
resource=Resource.create({
|
||||
"service.name": "shoppingcart",
|
||||
"service.instance.id": "instance-12",
|
||||
}),
|
||||
),

|
||||
<https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/resource/semantic_conventions/README.md>`_
|
||||
that have prescribed semantic meanings, for example ``service.name`` in the

|

For general information about sampling, see `the specification <https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/sdk.md#sampling>`_.
|
||||
|
||||
OpenTelemetry provides two types of samplers:
|
||||
|
||||
- `StaticSampler`
|
||||
- `TraceIdRatioBased`
|
||||
|
||||
A `StaticSampler` always returns the same sampling result regardless of the conditions. Both possible StaticSamplers are already created:
|
||||
|
||||
- Always sample spans: ALWAYS_ON
|
||||
- Never sample spans: ALWAYS_OFF
|
||||
|
||||
A `TraceIdRatioBased` sampler makes a random sampling result based on the sampling probability given.
|
||||
|
||||
If the span being sampled has a parent, `ParentBased` will respect the parent delegate sampler. Otherwise, it returns the sampling result from the given root sampler.
|
||||
|
||||
Currently, sampling results are always made during the creation of the span. However, this might not always be the case in the future (see `OTEP #115 <https://github.com/open-telemetry/oteps/pull/115>`_).
|
||||
|
||||
Custom samplers can be created by subclassing `Sampler` and implementing `Sampler.should_sample` as well as `Sampler.get_description`.
|
||||
|
||||
Samplers are able to modify the `mysql.opentelemetry.trace.span.TraceState` of the parent of the span being created. For custom samplers, it is suggested to implement `Sampler.should_sample` to utilize the
|
||||
parent span context's `mysql.opentelemetry.trace.span.TraceState` and pass into the `SamplingResult` instead of the explicit trace_state field passed into the parameter of `Sampler.should_sample`.
|
||||
|
||||
To use a sampler, pass it into the tracer provider constructor. For example:
|
||||
|
||||
.. code:: python
|
||||
|
||||
from opentelemetry import trace
|
||||
from mysql.opentelemetry.sdk.trace import TracerProvider
|
||||
from mysql.opentelemetry.sdk.trace.export import (
|
||||
ConsoleSpanExporter,
|
||||
SimpleSpanProcessor,
|
||||
)
|
||||
from mysql.opentelemetry.sdk.trace.sampling import TraceIdRatioBased
|
||||
|
||||
# sample 1 in every 1000 traces
|
||||
sampler = TraceIdRatioBased(1/1000)
|
||||
|
||||
# set the sampler onto the global tracer provider
|
||||
trace.set_tracer_provider(TracerProvider(sampler=sampler))
|
||||
|
||||
# set up an exporter for sampled spans
|
||||
trace.get_tracer_provider().add_span_processor(
|
||||
SimpleSpanProcessor(ConsoleSpanExporter())
|
||||
)
|
||||
|
||||
# created spans will now be sampled by the TraceIdRatioBased sampler
|
||||
with trace.get_tracer(__name__).start_as_current_span("Test Span"):
|
||||
...
|
||||
|
||||
The tracer sampler can also be configured via environment variables ``OTEL_TRACES_SAMPLER`` and ``OTEL_TRACES_SAMPLER_ARG`` (only if applicable).
|
||||
The list of built-in values for ``OTEL_TRACES_SAMPLER`` are:
|
||||
|
||||
* always_on - Sampler that always samples spans, regardless of the parent span's sampling decision.

Sampling probability can be set with ``OTEL_TRACES_SAMPLER_ARG`` if the sampler is traceidratio or parentbased_traceidratio. Rate must be in the range [0.0,1.0]. When not provided rate will be set to
|
||||
1.0 (maximum rate possible).
|
||||
|
||||
Prev example but with environment variables. Please make sure to set the env ``OTEL_TRACES_SAMPLER=traceidratio`` and ``OTEL_TRACES_SAMPLER_ARG=0.001``.

When utilizing a configurator, you can configure a custom sampler. In order to create a configurable custom sampler, create an entry point for the custom sampler
|
||||
factory method or function under the entry point group, ``opentelemetry_traces_sampler``. The custom sampler factory method must be of type ``Callable[[str], Sampler]``, taking a single string argument and
|
||||
returning a Sampler object. The single input will come from the string value of the ``OTEL_TRACES_SAMPLER_ARG`` environment variable. If ``OTEL_TRACES_SAMPLER_ARG`` is not configured, the input will
|
||||
be an empty string. For example:
|
||||
|
||||
.. code:: python
|
||||
|
||||
setup(
|
||||
...
|
||||
entry_points={
|
||||
...
|
||||
"opentelemetry_traces_sampler": [
|
||||
"custom_sampler_name = path.to.sampler.factory.method:CustomSamplerFactory.get_sampler"
|
||||
]
|
||||
}
|
||||
)
|
||||
# ...
|
||||
class CustomRatioSampler(Sampler):
|
||||
def __init__(rate):
|
||||
# ...
|
||||
# ...
|
||||
class CustomSamplerFactory:
|
||||
@staticmethod
|
||||
get_sampler(sampler_argument):
|
||||
try:
|
||||
rate = float(sampler_argument)
|
||||
return CustomSampler(rate)
|
||||
except ValueError: # In case argument is empty string.
|
||||
return CustomSampler(0.5)
|
||||
|
||||
In order to configure you application with a custom sampler's entry point, set the ``OTEL_TRACES_SAMPLER`` environment variable to the key name of the entry point. For example, to configured the
|
||||
above sampler, set ``OTEL_TRACES_SAMPLER=custom_sampler_name`` and ``OTEL_TRACES_SAMPLER_ARG=0.5``.
