Return whether or not a server is available

GET /_admin/server/availability

Return availability information about a server.

This is a public API so it does not require authentication. It is meant to be used only in the context of server monitoring.

Responses

200 OK
This API will return HTTP 200 in case the server is up and running and usable for arbitrary operations, is not set to read-only mode and is currently not a follower in case of an Active Failover deployment setup.
503 Service Unavailable
HTTP 503 will be returned in case the server is during startup or during shutdown, is set to read-only mode or is currently a follower in an Active Failover deployment setup.
In addition, HTTP 503 will be returned in case the fill grade of the scheduler queue exceeds the configured high-water mark (adjustable via startup option --server.unavailability-queue-fill-grade), which by default is set to 75 % of the maximum queue length.

Get the required database version (deprecated)

GET /_admin/database/target-version

This endpoint is deprecated and should no longer be used. It will be removed from version 3.12.0 onward. Use GET /_api/version instead.

Returns the database version that this server requires. The version is returned in the version attribute of the result.

Responses

200 OK
Is returned in all cases.

Get information about the deployment

GET /_db/_system/_admin/support-info

Retrieves deployment information for support purposes. The endpoint returns data about the ArangoDB version used, the host (operating system, server ID, CPU and storage capacity, current utilization, a few metrics) and the other servers in the deployment (in case of cluster deployments).

As this API may reveal sensitive data about the deployment, it can only be accessed from inside the _system database. In addition, there is a policy control startup option --server.support-info-api that controls if and to whom the API is made available.

Responses

200 OK
- date* string
  ISO 8601 datetime string of when the information was requested.
- deployment* object
  An object with at least a type attribute, indicating the deployment mode.
  In case of a "single" server, additional information is provided in the top-level host attribute.
  In case of a "cluster", there is a servers object that contains a nested object for each Coordinator and DB-Server, using the server ID as key. Each object holds information about the ArangoDB instance as well as the host machine. There are additional attributes for the number of agents, coordinators, dbServers, and shards.
- host object
  An object that holds information about the ArangoDB instance as well as the host machine. Only set in case of single servers.
404 Not Found
The support info API is turned off.

Shutdown

Start the shutdown sequence

DELETE /_db/{database-name}/_admin/shutdown

This call initiates a clean shutdown sequence. Requires administrative privileges.

Path Parameters

database-name* string
The name of a database. Which database you use doesn’t matter as long as the user account you authenticate with has at least read access to this database and administrate access to the _system database.

Query Parameters

soft boolean
Introduced in: v3.7.12, v3.8.1, v3.9.0
If set to true, this initiates a soft shutdown. This is only available on Coordinators. When issued, the Coordinator tracks a number of ongoing operations, waits until all have finished, and then shuts itself down normally. It will still accept new operations.
This feature can be used to make restart operations of Coordinators less intrusive for clients. It is designed for setups with a load balancer in front of Coordinators. Remove the designated Coordinator from the load balancer before issuing the soft-shutdown. The remaining Coordinators will internally forward requests that need to be handled by the designated Coordinator. All other requests will be handled by the remaining Coordinators, reducing the designated Coordinator’s load.
The following types of operations are tracked:
- AQL cursors (in particular streaming cursors)
- Transactions (in particular stream transactions)
- Pregel runs (conducted by this Coordinator)
- Ongoing asynchronous requests (using the x-arango-async: store HTTP header)
- Finished asynchronous requests, whose result has not yet been collected
- Queued low priority requests (most normal requests)
- Ongoing low priority requests

HTTP Headers

Responses

200 OK
is returned in all cases, OK will be returned in the result buffer on success.

Miscellaneous actions

Compact all databases

PUT /_admin/compact

This command can cause a full rewrite of all data in all databases, which may take very long for large databases. It should thus only be used with care and only when additional I/O load can be tolerated for a prolonged time.

This endpoint can be used to reclaim disk space after substantial data deletions have taken place, by compacting the entire database system data.

The endpoint requires superuser access.

Request Body application/json object

changeLevel boolean
whether or not compacted data should be moved to the minimum possible level. The default value is false.
compactBottomMostLevel boolean
Whether or not to compact the bottommost level of data. The default value is false.

Responses

200 OK
Compaction started successfully
401 Unauthorized
if the request was not authenticated as a user with sufficient rights

Examples

curl -X PUT --header 'accept: application/json' --dump - 'http://localhost:8529/_admin/compact'

Execute a script

POST /_db/{database-name}/_admin/execute

Executes the JavaScript code in the body on the server as the body of a function with no arguments. If you have a return statement then the return value you produce will be returned as content type application/json. If the parameter returnAsJSON is set to true, the result will be a JSON object describing the return value directly, otherwise a string produced by JSON.stringify will be returned.

Note that this API endpoint will only be present if the server was started with the option --javascript.allow-admin-execute true.

The default value of this option is false, which disables the execution of user-defined code and disables this API endpoint entirely. This is also the recommended setting for production.

Path Parameters

database-name* string
The name of the database.

Query Parameters

HTTP Headers

Request Body application/json object

body* string
The request body is the JavaScript code to be executed.

Responses

200 OK
is returned when everything went well, or if a timeout occurred. In the latter case a body of type application/json indicating the timeout is returned. depending on returnAsJSON this is a json object or a plain string.
403 Forbidden
is returned if ArangoDB is not running in cluster mode.
404 Not Found
is returned if ArangoDB was not compiled for cluster operation.

Endpoints

The /_api/endpoint endpoint is deprecated. For cluster deployments, you can use /_api/cluster/endpoints instead to find all current Coordinator endpoints. See Cluster.

An ArangoDB server can listen for incoming requests on multiple endpoints.

The endpoints are normally specified either in the arangod configuration file or on the command-line, using the --server.endpoint startup option. The default endpoint for ArangoDB is tcp://127.0.0.1:8529 (IPv4 localhost on port 8529 over the HTTP protocol).

Note that all endpoint management operations can only be accessed via the default _system database and none of the other databases.

List the endpoints of a single server (deprecated)

GET /_db/_system/_api/endpoint

This route should no longer be used. It is considered as deprecated from version 3.4.0 on.

Returns an array of all configured endpoints the server is listening on.

The result is a JSON array of JSON objects, each with "entrypoint" as the only attribute, and with the value being a string describing the endpoint.

Retrieving the array of all endpoints is allowed in the system database only. Calling this action in any other database will make the server return an error.

Responses

200 OK
is returned when the array of endpoints can be determined successfully.
400 Bad Request
is returned if the action is not carried out in the system database.
405 Method Not Allowed
The server will respond with HTTP 405 if an unsupported HTTP method is used.

Examples

curl --header 'accept: application/json' --dump - 'http://localhost:8529/_api/endpoint'
