Access Log Reference

Public Preview

Access logs are delivered in JSON Lines format - one JSON object per line. Each line is a self-contained JSON object representing a single operation. The following example shows a log entry of the Search operation:

{
    "action": "Search",
    "cluster_id": "inxx-xxxxxxxxxxxxxxx",
    "database": "default",
    "date": "2026/04/14 06:31:16.827 +00:00",
    "interface": "Restful",
    "log_type": "ACCESS",
    "params": {
        "collection": "ccc1",
        "consistency_level": 2,
        "execution_time": "15.368706ms",
        "expr": "",
        "input_params": {
            "anns_field": "",
            "offset": "0",
            "params": "{}",
            "round_decimal": "-1",
            "topk": "10"
        },
        "nq": 1,
        "output_fields": ["*"],
        "partition": null,
        "result_num": 10,
        "result_pks": [55, 19, 18, 10, -26, 115, -14, -96, -50, 9],
        "result_scores": [0.87269604, 0.8639183, 0.8605273, 0.85245466, 0.8490447, 0.84537137, 0.84066796, 0.8314183, 0.8296911, 0.82586515],
        "topk": 10
    },
    "result": 0,
    "status": "Success",
    "timestamp": 1776148276827,
    "trace_id": "f89903d701329910380442aa86941be9",
    "user": "key-ibchakktguxxrvvxseoasz"
}

In practice, each entry occupies a single line in the .log file. The sections below describe each field in detail.

Log field schema

Field	Required	Type	Description	Example
action	Yes	string	The operation name. See Supported actions.	"Search"
cluster_id	Yes	string	The unique identifier of the cluster.	"inxx-xxxxxxxxxxxxxxx"
database	No	string	The database where the operation occurred.	"default"
date	Yes	string	Human-readable timestamp with timezone.	"2026/04/14 06:31:16.827 +00:00"
interface	Yes	string	The interface type: Restful or Grpc.	"Restful"
log_type	Yes	string	Log category: ACCESS, AUDIT, or SLOW.	"ACCESS"

user	Yes	string	The user or API key that issued the request.	"key-ibchakktguxxrvvxseoasz"

params fields

Field	Required	Type	Description	Example

params.consistency_level	No	int	The consistency level used for the operation.	2
params.execution_time	No	string	Server-side execution time, measured from when the proxy receives the full payload to when it begins sending the response. Does not include network transit time.	"15.368706ms"
params.expr	No	string or array	The filter expression passed with the request. For HybridSearch, this is an array of expressions (one per sub-request).	"" or [""]

params.limit	No	int	The limit on the number of results to return. Appears for Query and HybridSearch actions.	100
params.nq	No	int	The number of query vectors. Appears for Search actions.	1
params.output_fields	No	array	The output fields requested in the query.	["*"]
params.partition	No	string	The target partition, if specified. null when no partition is specified.	null
params.result_num	No	int	The actual number of results returned by the operation.	10
params.result_pks	No	array	The primary keys in the query result. Appears for Search, HybridSearch, and Query actions when output params are configured to include it.	[55, 19, 18, 10]
params.result_scores	No	array	The similarity scores corresponding to each entry in params.result_pks. Appears for Search and HybridSearch actions.	[0.87269604, 0.8639183]
params.topk	No	int	The topk parameter for the search request. Appears for Search and HybridSearch actions.	10

Supported actions

This release logs search- or query-class actions only:

Action	Description
Search	Vector similarity search
HybridSearch	Multi-vector search with reranking
Query	Scalar filtering query

📘Notes

Support for additional actions is planned for a future release.

File path and naming

Log files are organized in your object storage bucket with the following path structure:

/<Cluster ID>/<Log type>/<Date>/<File name><File name suffix>

Component	Format	Example
Cluster ID	The cluster's unique identifier	inxx-xxxxxxxxxxxxxxx
Log type	access, audit, or slow	access
Date	ISO date (YYYY-MM-DD)	2024-12-20
File name	HH:MM:SS-<UUID>, where HH:MM:SS is the UTC time and <UUID> is a random string for uniqueness	09:16:53-jz5l7D8Q
File name suffix	.log	.log

Full path example:

/inxx-xxxxxxxxxxxxxxx/access/2024-12-20/09:16:53-jz5l7D8Q.log
