Openobserve API

OpenObserve REST API Skill

Programmatic OpenObserve usage for AI agents. Talk to any OpenObserve instance (Cloud or self-hosted) using curl and the documented REST API. No CLI required — there is no first-party OpenObserve CLI.

Retrieval First

Your knowledge of OpenObserve API shapes may be outdated. Prefer retrieval over pre-training:

When docs and server source disagree, trust the server source — handlers ship faster than docs.

1. Auth

HTTPS basic auth with email + password. There is no token endpoint.

# Method 1: curl -u shorthand
curl -u "you@example.com:PASSWORD" "https://eu1.openobserve.ai/api/<org>/streams"

# Method 2: explicit header
TOKEN=$(printf '%s' "you@example.com:PASSWORD" | base64)
curl -H "Authorization: Basic $TOKEN" "https://eu1.openobserve.ai/api/<org>/streams"

Endpoints below assume BASE=https://<host>/api/<org> and AUTH="-u you@example.com:PASSWORD".

2. Search / Query — POST $BASE/_search

Optional query string ?type=logs|metrics|traces (default logs).

curl $AUTH -H 'Content-Type: application/json' \
  "$BASE/_search?type=logs" \
  -d '{
    "query": {
      "sql": "SELECT host_name, COUNT(*) AS n FROM \"my_stream\" GROUP BY host_name ORDER BY n DESC",
      "start_time": 1777000000000000,
      "end_time":   1777999999000000,
      "from": 0,
      "size": 100
    },
    "search_type": "ui"
  }'

• Timestamps are microseconds (Unix epoch × 1_000_000). Always set start_time/end_time — missing them scans everything.
• search_type ∈ ui | dashboards | reports | alerts — affects rate limits and audit logs.
• Pagination: from (offset) + size (limit, max ~10000 per request).
• Response: { took, hits[], total, from, size, scan_size }.
• SQL flavor: DataFusion / Arrow SQL. Identifiers in double quotes ("stream_name"), strings in single quotes ('value').
• Time-bucketed group by: SELECT histogram(_timestamp, '5 minute') AS ts, COUNT(*) FROM "stream" GROUP BY ts ORDER BY ts.
• Term aggregation: SELECT k8s_namespace, COUNT(*) FROM "stream" GROUP BY k8s_namespace.
• Full-text: match_all('text'), str_match(field, 'text'). Default full-text fields: log, message, msg, content, data, json.
• PromQL on metrics: POST $BASE/prometheus/api/v1/query_range.
• Trace context window: GET $BASE/{stream}/_around?key=<ts_us>&size=N.

3. Streams — GET $BASE/streams

# List
curl $AUTH "$BASE/streams?fetchSchema=false&type=logs"

# Schema
curl $AUTH "$BASE/streams/<stream>/schema?type=logs"

# Update settings
curl $AUTH -X PUT -H 'Content-Type: application/json' "$BASE/streams/<stream>/settings" -d '{"partition_keys":["host_name"]}'

# Delete
curl $AUTH -X DELETE "$BASE/streams/<stream>?type=logs"

Field types: Utf8 | Int64 | Float64 | Timestamp | Boolean. Timestamp field is always _timestamp (microseconds).

4. Dashboards — GET|POST|PUT|DELETE $BASE/dashboards

All take ?folder=<folder_id> (default default).

# List
curl $AUTH "$BASE/dashboards?folder=default"

# Get one (returns versioned wrapper {v1..v8, version, hash, updatedAt})
curl $AUTH "$BASE/dashboards/<dashboard_id>?folder=default"

# Create — body is the UNWRAPPED inner v8 object
curl $AUTH -X POST -H 'Content-Type: application/json' \
  "$BASE/dashboards?folder=default" \
  -d @dashboard-v8.json

# Update — REQUIRES the current hash for optimistic concurrency
HASH=$(curl -s $AUTH "$BASE/dashboards/<id>?folder=default" | jq -r .hash)
curl $AUTH -X PUT -H 'Content-Type: application/json' \
  "$BASE/dashboards/<id>?folder=default&hash=$HASH" \
  -d @updated-dashboard.json

# Delete
curl $AUTH -X DELETE "$BASE/dashboards/<id>?folder=default"

# Move between folders
curl $AUTH -X PUT -H 'Content-Type: application/json' \
  "$BASE/folders/dashboards/<id>" \
  -d '{"from":"default","to":"<target_folder_id>"}'

Critical: PUT/POST body must be the unwrapped inner v8 object, not the full {v1..v8, version, hash} wrapper. The server returns the wrapper but expects you to send only the inner object back.

# Read, mutate, write — the correct pattern
RAW=$(curl -s $AUTH "$BASE/dashboards/<id>?folder=default")
HASH=$(echo "$RAW" | jq -r .hash)
echo "$RAW" | jq '.v8 | .title = "New Title"' \
  | curl -s $AUTH -X PUT -H 'Content-Type: application/json' \
    "$BASE/dashboards/<id>?folder=default&hash=$HASH" -d @-

A 409 Conflict response means the hash is stale — refetch and retry.

Per-panel operations (v8 only — return new hash)

# Add panel
curl $AUTH -X POST -H 'Content-Type: application/json' \
  "$BASE/dashboards/<id>/panels?folder=default&hash=$HASH" \
  -d '{"panel": {...}, "tabId": "default"}'

# Update panel
curl $AUTH -X PUT -H 'Content-Type: application/json' \
  "$BASE/dashboards/<id>/panels/<panel_id>?folder=default&hash=$HASH" \
  -d '{...panel...}'

# Delete panel
curl $AUTH -X DELETE \
  "$BASE/dashboards/<id>/panels/<panel_id>?folder=default&hash=$HASH&tabId=default"

5. Panel JSON (v8)

The dashboard tree: dashboard.tabs[].panels[]. Each panel:

{
  "id": "panel-1",
  "type": "table",
  "title": "Per-host stats",
  "description": "",
  "queryType": "sql",
  "queries": [
    {
      "query": "SELECT host_name, COUNT(*) AS n FROM \"my_stream\" GROUP BY host_name ORDER BY n DESC",
      "vrlFunctionQuery": "",
      "customQuery": true,
      "fields": {
        "stream": "my_stream",
        "stream_type": "logs",
        "x": [
          { "label": "Host", "alias": "host_name", "column": "host_name", "color": null, "aggregationFunction": null }
        ],
        "y": [
          {
            "label": "Count",
            "alias": "n",
            "column": "n",
            "color": null,
            "aggregationFunction": null,
            "treatAsNonTimeseries": true
          }
        ],
        "z": [],
        "breakdown": [],
        "filter": { "filterType": "group", "logicalOperator": "AND", "conditions": [] }
      },
      "config": { "promql_legend": "", "layer_type": "scatter", "weight_fixed": 1, "limit": 0, "min": 0, "max": 100 }
    }
  ],
  "config": {
    "show_legends": true,
    "decimals": 2,
    "unit": "currency",
    "unit_custom": "USD"
  },
  "layout": { "x": 0, "y": 0, "w": 48, "h": 14, "i": 1 }
}

Panel type values

metric (single big number) · table · bar · h-bar · stacked · h-stacked · line · area · area-stacked · scatter · pie · donut · heatmap · gauge · geomap · maps · sankey · html · markdown.

Layout grid

The grid is 96 columns wide (verified via inspection of returned panel layouts on April 2026 OpenObserve Cloud). Older docs mention 192 or 48 — when in doubt, GET an existing dashboard from the same org and copy the w values you see. Heights are unitless rows (h: 7 = small metric panel; h: 14 = standard table).

Useful config keys

6. Critical pitfalls

6a. Re-aggregation when customQuery: true — the most common bug.

If your hand-written SQL already contains COUNT(*), SUM(...), AVG(...) etc., every entry in fields.y (and fields.x) must set aggregationFunction: null. Default 'sum' causes OpenObserve to wrap the already-aggregated column in another aggregation client-side, producing duplicate rows and wildly inflated numbers.

// WRONG — produces duplicate rows
"y": [{"column":"messages", "aggregationFunction":"count"}]

// RIGHT — SQL already did the aggregation
"y": [{"column":"messages", "aggregationFunction":null, "treatAsNonTimeseries":true}]

6b. Multiple fields.y on Table panels — each Y entry can render as a separate series/row. For a Table that should display one row per group, put only one entry in fields.y (any one column); the renderer will then display all SQL columns as table columns.

6c. Metric panels with customQuery: true — must explicitly map the result column to fields.y:

"y": [{"label":"Value", "alias":"value", "column":"value", "aggregationFunction":"sum", "treatAsNonTimeseries":false}]

The metric panel needs to know which column is the number to display.

6d. ROUND + wildcard timestamp expansion — OpenObserve's planner sometimes auto-injects _timestamp into queries that wrap SUM(col) in ROUND(...), producing Column "_timestamp" must appear in the GROUP BY clause errors. Workaround: drop ROUND() and use the panel's decimals config instead, or pre-cast: CAST(SUM(...) AS DOUBLE).

6e. Hash-based concurrency on PUT — every successful PUT changes the dashboard hash. If you mutate a dashboard from two scripts back-to-back, the second one needs to refetch. Always re-GET before each PUT to grab the current hash.

6f. start_time/end_time are microseconds — Date.now() * 1000, not milliseconds. Off-by-1000× returns no hits but no error.

7. Folders / alerts / ingestion

Folders (v2 API):

curl $AUTH "$BASE/folders/dashboards" # list
curl $AUTH -X POST "$BASE/folders/dashboards" -d '{"name":"my-folder"}'
curl $AUTH "$BASE/folders/dashboards/name/<folder_name>" # lookup by name

folder_type ∈ dashboards | alerts | reports.

Alerts:

curl $AUTH "$BASE/{stream}/alerts" # list per-stream
curl $AUTH -X POST "$BASE/{stream}/alerts" -d '{...}'
# templates and destinations are referenced by alert definitions:
curl $AUTH "$BASE/alerts/templates"
curl $AUTH "$BASE/alerts/destinations"

Ingestion (POST your own data in):

# JSON
curl $AUTH -X POST "$BASE/<stream>/_json" -d '[{"event":"foo","level":"info"}]'

# Multi-line JSON (one per line)
curl $AUTH -X POST "$BASE/<stream>/_multi" --data-binary @file.ndjson

# Elasticsearch bulk
curl $AUTH -X POST "$BASE/_bulk" --data-binary @bulk.txt

# OTLP HTTP
curl $AUTH -X POST "$BASE/v1/logs" -d @otlp-logs.json
curl $AUTH -X POST "$BASE/v1/traces" -d @otlp-traces.json
curl $AUTH -X POST "$BASE/v1/metrics" -d @otlp-metrics.json

# Loki
curl $AUTH -X POST "$BASE/loki/api/v1/push" -d @loki.json

# Prometheus remote-write (binary protobuf)
curl $AUTH -X POST "$BASE/prometheus/api/v1/write" --data-binary @write.pb

8. Common recipes

Get top hosts by message count (last 24h):

NOW=$(($(date +%s) * 1000000))
DAY=$((NOW - 86400 * 1000000))
curl $AUTH -H 'Content-Type: application/json' \
  "$BASE/_search?type=logs" \
  -d "{\"query\":{\"sql\":\"SELECT host_name, COUNT(*) AS n FROM \\\"my_stream\\\" GROUP BY host_name ORDER BY n DESC\",\"start_time\":$DAY,\"end_time\":$NOW,\"size\":50}}"

Add a metric panel to an existing dashboard (single-shot, hash-aware):

DASH_ID=<dashboard_id>
HASH=$(curl -s $AUTH "$BASE/dashboards/$DASH_ID?folder=default" | jq -r .hash)
curl $AUTH -X POST -H 'Content-Type: application/json' \
  "$BASE/dashboards/$DASH_ID/panels?folder=default&hash=$HASH" \
  -d '{
    "tabId": "default",
    "panel": {
      "id": "p-cost",
      "type": "metric",
      "title": "Total cost (USD)",
      "queryType": "sql",
      "queries": [{
        "query": "SELECT SUM(CAST(cost_usd AS DOUBLE)) AS value FROM \"my_stream\"",
        "customQuery": true,
        "fields": {
          "stream":"my_stream", "stream_type":"logs",
          "x":[], "z":[], "breakdown":[],
          "y":[{"label":"Value","alias":"value","column":"value","aggregationFunction":"sum","treatAsNonTimeseries":false}],
          "filter":{"filterType":"group","logicalOperator":"AND","conditions":[]}
        },
        "config":{}
      }],
      "config": {"unit":"currency","unit_custom":"USD","decimals":2},
      "layout": {"x":0,"y":0,"w":32,"h":7,"i":99}
    }
  }'

Build a complete dashboard from scratch: GET an existing dashboard's panel JSON as a template (it's the safest way to learn the exact field shapes the server will accept), then mutate the tabs[0].panels array and PUT the unwrapped v8 body back. See the references/recipes/build-dashboard.sh script that ships with this skill for a working example.

9. SDKs / clients (no first-party CLI)

For most agent tasks, plain curl against the REST API is the right tool — the SDKs add little value over an HTTP request and lag the server feature set.
