Configure CubeAPM

CubeAPM can be configured through command line arguments, configuration file, or environment variables. In case of environment variables, please prefix (CUBE_) and replace dots (.) and dashes (-) with underscores (_) in variable names. For example:

# command line parameter
--metrics.update-interval 30s

# configuration file
metrics.update-interval=30s

# environment variable
CUBE_METRICS_UPDATE_INTERVAL=30s

If a parameter if specified through multiple means, the following order of preference applies (highest at top):

  1. Command line arguments
  2. Environment variables
  3. Configuration file
  4. Default values set in code

Essential Configuration​

CubeAPM provides reasonable defaults to configuration parameters wherever possible. However, some parameters do not have reasonable default values and therefore their values must be provided at the time of setup for CubeAPM to start up. Following is a list of such parameters:

  1. token
  2. smtp.url
  3. database.url
  4. auth.database.url
  5. auth.key.session
  6. auth.key.tokens

In addition, the following configuration parameters have some default value, but it is quite likely that you may need to override them as per your environment for CubeAPM to work properly.

  1. base-url
  2. auth.sys-admins
  3. cluster.peers
  4. smtp.from
  5. time-zone
info

For security reasons, CubeAPM requires HTTPS. Hence, it needs to be deployed behind a load balancer or reverse proxy with SSL termination capability.

However, for ease of initial exploration, HTTP can be used with localhost/127.0.0.1 only.

If you want to allow HTTP, set auth.cookie.insecure=true (see Configuration Reference below).

Configuration Reference​

Below is the list of all configuration parameters supported by CubeAPM, along with documentation and default values.

## CubeAPM configuration parameters


## Mandatory Parameters: CubeAPM will not start if any of these is not provided

# Account token obtained from CubeAPM. This token is used for authentication with CubeAPM.
token=

# URL of SMTP server for sending emails, e.g., reset password email, alert notifications.
# Example:
#  smtp.url=smtp://<username>:<password>@<mailserver>:25/?disable_starttls=false
# Note: username and password must be url-encoded to escape any special characters.
smtp.url=

# URL of database for storing config data (settings, dashboards, etc.).
# Example:
#  database.url=mysql://<username>:<password>@tcp(<host>:3306)/<db_name>
#  database.url=postgres://<username>:<password>@<host>:5432/<db_name>?sslmode=disable
# Note: A-Za-z0-9.-_ characters are safe for use in password. Other characters can cause problems.
database.url=

# URL of database for storing user accounts data.
# Example:
#  auth.database.url=mysql://<username>:<password>@tcp(<host>:3306)/<db_name>
#  auth.database.url=postgres://<username>:<password>@<host>:5432/<db_name>?sslmode=disable
# Note: A-Za-z0-9.-_ characters are safe for use in password. Other characters can cause problems.
auth.database.url=

# Encryption key for session data. Must be 32 characters long. Can use hex encoded UUID without dashes.
auth.key.session=

# Encryption key for tokens. Must be 32 characters long. Can use hex encoded UUID without dashes.
auth.key.tokens=



## Important Parameters: You will quite likely need to set these as per your environment for CubeAPM to work properly.

# URL used by users to access CubeAPM. This is used to generate URLs in emails and alerts.
# If you use reverse proxy and sub path specify full url (with sub path).
# Examples: http://cube.yourdomain.com, https://yourdomain.com/cube, http://10.0.0.1:3125
base-url=http://localhost:3125

# Comma separated list of email ids of users to be given sysadmin privilege.
auth.sys-admins=

# Allow authentication over HTTP. By default, CubeAPM sets secure attribute on cookies so the cookies are sent only over HTTPS.
auth.cookie.insecure=false

# Comma separated list of all nodes in the cluster, e.g., 10.0.0.1,10.0.0.2,10.0.0.3. Leave empty for single node operation.
cluster.peers=

# Email address of sender. Your SMTP server must be configured to allow sending emails from this address.
smtp.from=no-reply@cubeapm.com

# Timezone of CubeAPM users. While most of the timezone related operations are done on the browser using browser's time zone setting, a few operations need to be performed on the server and they use this setting.
# Examples: America/Los_Angeles, Asia/Kolkata, UTC
time-zone=UTC
