To enable and collect health checks and metrics, services must be configured with a “management token”.
Services must have ManagementToken configured. This is used to authorize access monitoring endpoints. If ManagementToken is not configured, monitoring endpoints will return the error 404 disabled
.
To access a monitoring endpoint, the requester must provide the HTTP header Authorization: Bearer (ManagementToken)
.
Set port
(the listen port) and ManagementToken
in the Manage
section of node-manager.ini
.
[Manage] # The management server responds to http://addr:port/status.json with # a snapshot of internal state. # Management server listening address (default 127.0.0.1) #address = 0.0.0.0 # Management server port number (default -1, server is disabled) #port = 8989 ManagementToken = xxx
The following services also support monitoring.
Set ManagementToken
in the appropriate section of /etc/arvados/config.yml
.
Clusters:
ClusterID:
# Token to be included in all healthcheck requests. Disabled by default.
# Server expects request header of the format "Authorization: Bearer xxx"
ManagementToken: xxx
