  "$OSD_ENDPOINT/api/saved_objects/index-pattern/<INDEX_PATTERN_ID>" \

Dataset Discovery

Datasets are an evolution of index patterns that classify indices by signal type (logs, traces, metrics). Users define which indices are logs vs traces through the Dashboards UI. See Dataset Discovery documentation for details.

To discover datasets programmatically, query the saved objects API for index patterns with their signalType, displayName, and description fields:

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?fields=title&fields=type&fields=displayName&fields=signalType&fields=description&per_page=10000&type=index-pattern" \
  -H 'osd-xsrf: true'

Index patterns created by the observability stack init script include schema mappings that identify their signal type (e.g., otelLogs for log indices, trace-specific time fields for trace indices). These mappings are visible in the index pattern's attributes.fields property.

APM Configuration

Get APM Correlation Config

The APM plugin stores correlations saved objects that define how traces, logs, and metrics are linked. Two correlation types are created by the init script:

• trace-to-logs-* — Links a trace index pattern to a log index pattern for cross-signal navigation
• APM-Config-* — Ties together the traces index, service map index, and Prometheus datasource for the APM UI

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=correlations&per_page=100" \
  -H 'osd-xsrf: true'

Workspace-Scoped APM Config

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/w/<WORKSPACE_ID>/api/saved_objects/_find?type=correlations&per_page=100" \
  -H 'osd-xsrf: true'

Saved Objects

Count Saved Objects by Type

The _find API requires a type parameter. To get a count without loading objects, use per_page=0:

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=index-pattern&per_page=0" \
  -H 'osd-xsrf: true'

Common saved object types: index-pattern, query, dashboard, visualization, config, correlations, data-source, data-connection, explore.

Find Correlations

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=correlations&per_page=100" \
  -H 'osd-xsrf: true'

Find Data Sources (OpenSearch)

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=data-source&per_page=100" \
  -H 'osd-xsrf: true'

Find Data Connections (Prometheus)

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=data-connection&per_page=100" \
  -H 'osd-xsrf: true'

Find Explore Panels

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=explore&per_page=100" \
  -H 'osd-xsrf: true'

Find Saved Queries

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=query&per_page=100" \
  -H 'osd-xsrf: true'

Find Dashboards

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=dashboard&per_page=100" \
  -H 'osd-xsrf: true'

Find Visualizations

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=visualization&per_page=100" \
  -H 'osd-xsrf: true'

Data Connections

List Prometheus Data Connections

To discover existing Prometheus data connections, use the saved objects API (the data-connection type):

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OSD_ENDPOINT/api/saved_objects/_find?type=data-connection&per_page=100" \
  -H 'osd-xsrf: true'

Create Prometheus Data Connection

The init script creates Prometheus data connections via the direct query API:

curl -s -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  -X POST "$OSD_ENDPOINT/api/directquery/dataconnections" \
  -H 'osd-xsrf: true' \
  -H 'Content-Type: application/json' \
  -d '{"name": "MyPrometheus", "connector": "prometheus", "allowedRoles": ["all_access"], "properties": {"prometheus.uri": "http://prometheus:9090", "prometheus.auth.type": "basicauth", "prometheus.auth.username": "", "prometheus.auth.password": ""}}'

Dynamic Index Discovery via OpenSearch API

When OSD is not available, query OpenSearch directly to discover indices and field mappings:

List All Observability Indices

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OPENSEARCH_ENDPOINT/_cat/indices?format=json&v" | python3 -c "
import sys, json
for idx in json.load(sys.stdin):
    name = idx['index']
    if any(p in name for p in ['otel-', 'logs-otel-', 'apm-']):
        print(f\"{name}  docs={idx['docs.count']}  size={idx['store.size']}\")"

Get Trace Index Field Mappings

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OPENSEARCH_ENDPOINT/otel-v1-apm-span-*/_mapping?pretty"

Get Log Index Field Mappings

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OPENSEARCH_ENDPOINT/logs-otel-v1-*/_mapping?pretty"

Get Service Map Index Field Mappings

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  "$OPENSEARCH_ENDPOINT/otel-v2-apm-service-map-*/_mapping?pretty"

PPL Describe for Field Discovery

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  -X POST "$OPENSEARCH_ENDPOINT/_plugins/_ppl" \
  -H 'Content-Type: application/json' \
  -d '{"query": "describe otel-v1-apm-span-000001"}'

curl -sk -u "$OPENSEARCH_USER:$OPENSEARCH_PASSWORD" \
  -X POST "$OPENSEARCH_ENDPOINT/_plugins/_ppl" \
  -H 'Content-Type: application/json' \
  -d '{"query": "describe logs-otel-v1-000001"}'

Default Index Patterns

When dynamic discovery is not possible, these are the default index patterns used by the observability stack:

Signal	Index Pattern	Description
Traces	otel-v1-apm-span-*	Trace span data with serviceName, traceId, spanId
Logs	logs-otel-v1-*	Log entries with resource.attributes.service.name
Service Maps	otel-v2-apm-service-map-*	Service topology with sourceNode, targetNode
