Nomad
nomad monitor export command reference
The nomad monitor export
command returns logs written to disk or journald by a nomad agent.
Usage
nomad monitor export [options]
Use the nomad monitor export
command to export an agent's historic data
from journald or its Nomad log file. If exporting journald logs, you must
pass -service-name
with the name of the systemd unit to query.
The -logs-since
and -follow
options are only valid for journald queries.
You may pass a duration string to the -logs-since
option to override the
default 72h duration. Nomad will accept the following time units in the
-logs-since
duration string: "ns", "us" (or "µs"), "ms", "s", "m", "h".
The -follow=true
option causes the agent to continue to stream logs until
interrupted or until the remote agent quits. Nomad only supports journald
queries on Linux.
If you do not use Linux or you do not run Nomad as a systemd unit, pass the
-on-disk=true
option to export the entirety of a given agent's nomad log file.
When ACLs are enabled, this command requires a token with the agent:read
capability.
Options
-node-id
: Specifies the client node-id to stream logs from. If no node-id is given, the Nomad server from the-address
flag is used.-server-id
: Specifies the Nomad server id to stream logs from. Accepts server names fromnomad server members
and also a specialleader
option which will target the current leader.-service-name
: Specifies the the name of the systemd unit for export. Do not use with-on-disk
. Must include 'nomad' and conform to systemd naming conventions. You may provide the full systemd file name or omit the suffix. If your service name includes a '.', you must include a valid suffix (e.g. nomad.client.service).-logs-since
: Duration used to determine how far back to return logs from journald. Ignored if used with-on-disk
and defaults to72h
if not set.-follow
: Boolean that, if true, continues streaming journald logs until interrupted. Do not use with-on-disk
-on-disk
: Boolean that, if true, returns the contents of the Nomad log file defined in the agent config.
Examples
