madsci.event_manager 0.4.7

The Modular Autonomous Discovery for Science (MADSci) Event and Logging Manager.

MADSci Event Manager

Handles distributed logging and events throughout a MADSci-powered Lab.

Features

• Centralized logging from distributed lab components
• Event querying with structured filtering
• Arbitrary event data support with standard schema
• Python logging-style log levels
• Alert notifications (email, etc.)

Installation

See the main README for installation options. This package is available as:

• PyPI: pip install madsci.event_manager
• Docker: Included in ghcr.io/ad-sdl/madsci
• Example configuration: See example_lab/managers/example_event.manager.yaml

Dependencies: MongoDB database (see the example_lab)

Usage

Quick Start

Use the example_lab as a starting point:

# Start with working example
docker compose up  # From repo root
# Event Manager available at http://localhost:8001/docs

# Or run standalone
python -m madsci.event_manager.event_server

Manager Setup

For custom deployments, create an Event Manager definition:

madsci manager add -t event_manager

See example_event.manager.yaml for configuration options.

Client

You can use MADSci's EventClient (madsci.client.event_client.EventClient) in your python code to log new events to the event manager, or fetch/query existing events.

from madsci.client.event_client import EventClient
from madsci.common.types.event_types import Event, EventLogLevel, EventType

event_client = EventClient(
    event_server="https://127.0.0.1:8001", # Update with the host/port you configured for your EventManager server
)

event_client.log_info("This logs a simple string at the INFO level, with event_type LOG_INFO")
event = Event(
    event_type="NODE_CREATE",
    log_level=EventLogLevel.DEBUG,
    event_data="This logs a NODE_CREATE event at the DEBUG level. The event_data field should contain relevant data about the event (in this case, something like the NodeDefinition, for instance)"
)
event_client.log(event)
event_client.log_warning(event) # Log the same event, but override the log level.

# Get the 50 most recent events
event_client.get_events(number=50)
# Get all events from a specific node
event_client.query_events({"source": {"node_id": "01JJ4S0WNGEF5FQAZG5KDGJRBV"}})

event_client.alert(event) # Will force firing any configured alert notifiers on this event

Alerts

The Event Manager provides some native alerting functionality. A default alert level can be set in the event manager definition's alert_level, which will determine the minimum log level at which to send an alert. Calls directly to the EventClient.alert method will send alerts regardless of the alert_level.

You can configure Email Alerts by setting up an EmailAlertsConfig (madsci.common.types.event_types.EmailAlertsConfig) in the email_alerts field of your EventManagerSettings.
