agent-info command dumps metrics and status information of a running
agent. The information displayed pertains to the specific agent the CLI
is connected to. This is useful for troubleshooting and performance monitoring.
nomad agent-info [options]
-address=<addr>: The address of the Nomad server. Overrides the
NOMAD_ADDRenvironment variable if set. Defaults to
-region=<region>: The region of the Nomad server to forward commands to. Overrides the
NOMAD_REGIONenvironment variable if set. Defaults to the Agent's local region.
-no-color: Disables colored command output. Alternatively,
NOMAD_CLI_NO_COLORmay be set.
-ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the
NOMAD_CACERTenvironment variable if set.
-ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both
-ca-certis used. Overrides the
NOMAD_CAPATHenvironment variable if set.
-client-cert=<path>: Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify
-client-key. Overrides the
NOMAD_CLIENT_CERTenvironment variable if set.
-client-key=<path>: Path to an unencrypted PEM encoded private key matching the client certificate from
-client-cert. Overrides the
NOMAD_CLIENT_KEYenvironment variable if set.
-tls-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the
NOMAD_TLS_SERVER_NAMEenvironment variable if set.
-tls-skip-verify: Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if
-token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the
NOMAD_TOKENenvironment variable if set.
Depending on the agent queried, information from different subsystems is returned. These subsystems are described below:
- client - Status of the local Nomad client
- nomad - Status of the local Nomad server
- serf - Gossip protocol metrics and information
- raft - Status information about the Raft consensus protocol
- runtime - Various metrics from the runtime environment
