riemann-client --version

riemann-client is a very simple tool to faciliate communication with a Riemann event stream processing server. It can be used both for sending events to one, and to query it too.

In both query and send mode, HOST and PORT default to localhost and 5555, respectively.

Query mode

In query mode, riemann-client takes one mandatory argument: the query itself. It must be a single argument, which will be sent to Riemann as-is, and the response dumped to the standard output, or, in case of an error, the error message will be written to the standard error.

See the Riemann documentation http://riemann.io/concepts.html for more information about the query syntax.

Apart from the mandatory argument, the riemann-client accepts the following options in query mode:

-j, --json

Print the result in JSON format, instead of the default, human-readable one.

Submit mode

In submit mode, riemann-client accepts the following options:

-s, --state STATE

The state the event should describe, free-form text, optional.

-S, --service SERVICE

The service the event is coming from.

-h, --host HOST

The host the event originates from. Not to be confused with the optional HOST parameter of riemann-client itself, which sets where to send the events to.

-D, --description DESCRIPTION

The description of the event, optional.

-t, --tag TAG

This option can be used multiple times to add tags to the event.

-a, --attribute NAME=VALUE

This option can be used multiple times to add custom attributes to the event.

-i, --metric-sint64 METRIC

Sets the metric for the event, using integer precision.

-d, --metric-d METRIC

Sets the metric of the event, using double precision.

-f, --metric-f METRIC

Sets the metric of the event, using floating point precision.

-L, --ttl TTL

An optional time-to-live of the event, in seconds (floating point number).

-T, --tcp

Send the event via TCP (the default).

-U, --udp

Send the event via UDP.

Sending an event

$ riemann-client send --state ok \
                      --service "client-test" \
                      --host "my-host" \
                      --description "A message from the Manual" \
                      --tag tag-1 --tag tag-2 \
                      --attribute x-manual=best-friend \
                      --metric-sint64 1 \
                      --ttl 300.5 \
                      --tcp

Querying Riemann

$ riemann-client query \'host = "my-host"\'
