Restful/JSON API documentation

This documentation describes the Glances API version 4 (Restful/JSON) interface.

An OpenAPI specification file is available at: https://raw.githubusercontent.com/nicolargo/glances/refs/heads/develop/docs/api/openapi.json

Run the Glances API server

The Glances Restful/API server could be ran using the following command line:

# glances -w --disable-webui

It is also ran automatically when Glances is started in Web server mode (-w).

If you want to enable the Glances Central Browser, use:

# glances -w --browser --disable-webui

API URL

The default root API URL is http://localhost:61208/api/4.

The bind address and port could be changed using the --bind and --port command line options.

It is also possible to define an URL prefix using the url_prefix option from the [outputs] section of the Glances configuration file.

Note: The url_prefix should always end with a slash (/).

For example:

[outputs]
url_prefix = /glances/

will change the root API URL to http://localhost:61208/glances/api/4 and the Web UI URL to http://localhost:61208/glances/

API documentation URL

The API documentation is embeded in the server and available at the following URL: http://localhost:61208/docs#/.

Authentication

Glances API supports both HTTP Basic authentication and JWT (JSON Web Token) Bearer authentication.

To enable authentication, start Glances with the --password option.

To generate a new login/password pair, use the following command:

glances -w --username
> Enter new username: foo
> Enter new password: ********
> Confirm new password: ********
> User 'username' created/updated successfully.

To reuse an existing login/password pair, start Glances with the -u <user> option:

glances -w -u foo

JWT Token Authentication

JWT authentication requires the python-jose library to be installed.

Step 1: Get a JWT Token

Request a token by sending your credentials to the token endpoint:

curl -X POST http://localhost:61208/api/4/token \
  -H "Content-Type: application/json" \
  -d '{"username": "your_username", "password": "your_password"}'

This will return a response like:

{
  "access_token": "...",
  "token_type": "bearer",
  "expires_in": 3600
}

Step 2: Use the Token

Use the token in the Authorization header with Bearer authentication:

# Store the token in a variable
TOKEN="your_access_token_here"

# Access a protected endpoint
curl -H "Authorization: Bearer $TOKEN" \
  http://localhost:61208/api/4/cpu

Complete Example:

# Get token and extract access_token
TOKEN=$(curl -s -X POST http://localhost:61208/api/4/token \
  -H "Content-Type: application/json" \
  -d '{"username": "glances", "password": "mypassword"}' \
  | grep -o '"access_token":"[^"]*"' \
  | cut -d'"' -f4)

# Use the token to get CPU stats
curl -H "Authorization: Bearer $TOKEN" \
  http://localhost:61208/api/4/cpu

Configuration:

You can configure JWT settings in the Glances configuration file:

[outputs]
# JWT secret key (if not set, a random key will be generated)
jwt_secret_key = your-secret-key-here
# JWT token expiration in minutes (default: 60)
jwt_expire_minutes = 60

Note: The token endpoint (/api/4/token) does not require authentication. Protected endpoints support both Bearer token and Basic Auth authentication methods.

Security

By default, Glances web server runs without authentication and binds to all network interfaces (0.0.0.0). This means any client that can reach the server on the network can access the full REST API, including sensitive system information such as process command-lines, which may contain credentials (passwords, API keys, tokens passed as arguments).

This default is intentional for ease of use on private, trusted networks (home labs, local machines, internal infrastructure). However, if your Glances instance is reachable from untrusted networks, you should take the following precautions:

Enable authentication by starting Glances with the --password option:

glances -w --password

Bind to localhost only if remote access is not needed:

glances -w --bind 127.0.0.1

Enable DNS rebinding protection by setting webui_allowed_hosts in glances.conf. This restricts the HTTP Host header values accepted by the web server. Without this setting, a DNS rebinding attack could allow an untrusted web page to read the REST API from a victim’s browser on the same network, even without direct network access to the Glances instance.

[outputs]
# Comma-separated list of allowed hostnames/IPs.
# Wildcards are supported (e.g. *.example.com).
webui_allowed_hosts=localhost,127.0.0.1,myserver.example.com

When webui_allowed_hosts is set, requests with a Host header not in the list are rejected with 400 Bad Request. When absent or commented out (the default), no host filtering is applied.

Use a reverse proxy (nginx, Caddy, Apache) with TLS and authentication for any public-facing or semi-public deployment. This is the recommended approach for production environments.

# Example: restrict bind to localhost, access via reverse proxy
# In glances.conf:
[outputs]
# Bind to localhost, let the reverse proxy handle external access
# then configure your reverse proxy to forward to 127.0.0.1:61208
webui_allowed_hosts=localhost,127.0.0.1

Note

The bind address (0.0.0.0 by default) controls which network interfaces the server listens on, but it is not a security boundary. For deployments on non-loopback interfaces, always set webui_allowed_hosts and consider enabling authentication.

CORS (Cross-Origin Resource Sharing) controls which external websites can make requests to the Glances API from a browser. By default, Glances allows requests from any origin (cors_origins=*) but does not allow credentials (cors_credentials=False). This means cross-origin requests work for unauthenticated API access, but browsers will not send stored credentials (e.g. Basic Auth) to the API from a third-party page.

If you need credentialed cross-origin access (e.g. a separate dashboard application that authenticates to Glances), you must configure explicit origins — the wildcard * combined with credentials is insecure and will be automatically rejected:

[outputs]
cors_origins=https://my-dashboard.internal.example.com
cors_credentials=True

Warning

Setting cors_credentials=True with cors_origins=* is not allowed. Glances will automatically disable credentials and log a warning if this combination is detected. This prevents a class of cross-site data theft attacks where any website could read your monitoring data.

When Glances is started without authentication or without host filtering, warning messages are displayed at startup to remind you of the risks.

WebUI refresh

It is possible to change the Web UI refresh rate (default is 2 seconds) using the following option in the URL: http://localhost:61208/?refresh=5

Fields descriptions:

  • total: Total physical memory available (unit is bytes)

  • available: The actual amount of available memory that can be given instantly to processes that request more memory in bytes; this is calculated by summing different memory values depending on the platform (e.g. free + buffers + cached on Linux) and it is supposed to be used to monitor actual memory usage in a cross platform fashion (unit is bytes)

  • percent: The percentage usage calculated as (total - available) / total * 100 (unit is percent)

  • used: Memory used, calculated differently depending on the platform and designed for informational purposes only (unit is bytes)

  • free: Memory not being used at all (zeroed) that is readily available; note that this doesn’t reflect the actual memory available (use ‘available’ instead) (unit is bytes)

  • active: (UNIX): memory currently in use or very recently used, and so it is in RAM (unit is bytes)

  • cached: (Linux, BSD): cache for various things (including ZFS cache) (unit is bytes)

  • wired: (BSD, macOS): memory that is marked to always stay in RAM. It is never moved to disk (unit is bytes)
