Nomad
Command: agent-info
The 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.
Usage
nomad agent-info [options]
When ACLs are enabled, this command requires a token with the agent:read
capability.
General Options
- -address=<addr>: The address of the Nomad server. Overrides the- NOMAD_ADDRenvironment variable if set. Defaults to- http://127.0.0.1:4646.
- -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. This option takes precedence over- -force-color.
- -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively,- NOMAD_CLI_FORCE_COLORmay be set. This option has no effect if- -no-coloris also used.
- -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-certand- -ca-pathare specified,- -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- NOMAD_SKIP_VERIFYis set.
- -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the- NOMAD_TOKENenvironment variable if set.
Agent Info Options
- -json: Output agent info in its JSON format.
- -t: Format and display agent info using a Go template.
Output
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
