AlertRecord - Fiddler Documentation

Alert record representing a triggered alert instance. An AlertRecord captures the details of a specific alert trigger event, including the metric values, thresholds, and context that caused an AlertRule to fire. Alert records provide essential data for monitoring analysis and troubleshooting.

Example

# List recent critical alerts
critical_alerts = [
    record for record in AlertRecord.list(
        alert_rule_id=drift_alert.id,
        start_time=datetime.now() - timedelta(days=3)
    )
    if record.severity == "CRITICAL"
]

# Analyze alert details
for alert in critical_alerts:

    print(f"Alert triggered at {alert.created_at}")
    print(f"Metric value: {alert.alert_value:.3f}")
    print(f"Critical threshold: {alert.critical_threshold:.3f}")
    if alert.feature_name:

        print(f"Feature: {alert.feature_name}")

        print(f"Message: {alert.message}")
        print("—")

        # Check for alert patterns
        hourly_alerts = {}
        for alert in AlertRecord.list(alert_rule_id=perf_alert.id):

            hour = alert.created_at.hour
            hourly_alerts[hour] = hourly_alerts.get(hour, 0) + 1

            print("Alerts by hour:", hourly_alerts)

Alert records are read-only entities created automatically by the Fiddler platform when AlertRules trigger. They cannot be created or modified directly but provide valuable historical data for analysis and debugging.

Initialize an AlertRecord instance. Creates an alert record object for representing triggered alert instances. Alert records are typically created automatically by the Fiddler platform when AlertRules trigger, rather than being instantiated directly by users.

Alert records are read-only entities that capture historical alert trigger events. They are created automatically by the system and cannot be modified after creation.

classmethod list()

List alert records triggered by a specific alert rule. Retrieves historical alert records for analysis and troubleshooting. This method provides access to all alert trigger events within a specified time range, enabling pattern analysis and threshold tuning.

Parameters

alert_rule_id

UUID | str

required

The unique identifier of the AlertRule to retrieve records for. Must be a valid alert rule UUID.

start_time

datetime | None

default:"7 days ago"

Start time for filtering alert records. If None, defaults to 7 days ago. Used to define the beginning of the query window.

end_time

datetime | None

default:"current time"

End time for filtering alert records. If None, defaults to current time. Used to define the end of the query window.

ordering

list[str] | None

default:"None"

List of field names for result ordering. Prefix with ”-” for descending order (e.g., [“-created_at”] for newest first).

Yields

AlertRecord – Alert record instances with complete trigger details and context information.

Returns

Iterator[AlertRecord]

Example

# Get recent alerts for analysis
recent_alerts = list(AlertRecord.list(
    alert_rule_id=drift_alert.id,
    start_time=datetime.now() - timedelta(days=3),
    ordering=["-created_at"]  # Newest first
))

# Analyze alert frequency
print(f"Total alerts in last 3 days: {len(recent_alerts)}")
critical_count = sum(1 for a in recent_alerts if a.severity == "CRITICAL")
print(f"Critical alerts: {critical_count}")

# Check alert patterns by feature
feature_alerts = {}
for alert in recent_alerts:

    if alert.feature_name:
        feature_alerts[alert.feature_name] = feature_alerts.get(alert.feature_name, 0) + 1

        print("Alerts by feature:", feature_alerts)

        # Analyze threshold violations
        for alert in recent_alerts[:5]:  # Latest 5 alerts

        violation_ratio = alert.alert_value / alert.critical_threshold
        print(f"Alert value: {alert.alert_value:.3f} "

        f"({violation_ratio:.1%} of threshold)")

Results are paginated automatically. The default time range is 7 days to balance performance with useful historical context. Use ordering parameters to get the most relevant results first.
