clojure.lang.ArityException: Wrong number of args (3) passed to: client$batch


I am new to closure and trying to setup Riemann to monitor server resources and application events. I have a Riemann server setup and am trying to add a Riemann client, which will forward events to the Riemann server.

This is my Riemann client configuration file:

; -*- mode: clojure; -*-
; vim: filetype=clojure

(logging/init :file "/var/log/riemann/riemann.log")

(require 'riemann.client)

; Listen on the local interface over TCP (5555), UDP (5555), and websockets (5556)
(let [host "0.0.0.0"]
  (tcp-server :host host)
  (udp-server :host host)
  (ws-server  :host host))

; Expire old events from the index.
(periodically-expire 10 {:keep-keys [:host, :service, :tags, :state, :description, :metric]})

(let [index (index)
      downstream (batch 100 1/10
        (async-queue! :agg { :queue-size 1e3
                             :core-pool-size 4
                             :max-pool-size 32}
      (forward
        (riemann.client/tcp-client :host "10.11.5.10"))))]

  (streams ; Inbound events will be passed to these streams:
    (default :ttl 60 ; Keep events in the index for 1 minute by default.
      index
      #(info %)
      (where (service #"^riemann.*") ; Send any events with service starting with riemann downstream
        downstream))))

Every time I try to start Riemann, I get the following exception printed to the logs:

ERROR [2016-05-17 14:58:58,118] main - riemann.bin - Couldn't start
clojure.lang.ArityException: Wrong number of args (3) passed to: client$batch

  at clojure.lang.RestFn.applyTo(RestFn.java:137)
  at riemann.bin.main(Unknown Source)

I lifted this configuration file (almost verbatim) from pg. 93 of The Art of Monitoring by James Turnbull. So I am confused what I could have done wrong. Can someone help me to understand why this configuration file is throwing a wrong number of args error?

Thanks


Solution

  • Your installed version of Riemann is ancient, you need 0.2.11+ to have a good time following that guide.

    You can get the rpm at http://riemann.io
