Riemann interaction with custom service ?

[vijaySamanuri]

Hi,

I am using "collectd" monitoring tool to collect metrics and sending them as events to riemann using write_riemann plugin.
I am very new to riemann, so i thought it is better to ask here before i proceed further.
my question : is there a way to invoke or call http rest api through riemann if a certain condition is met.
for example, if cpu usage >=90% for certain time interval (say 1 minute) i need to trigger my own service (written in java) along with email alerts.

help me .. and please correct me if am going in the wrong direction !! Thanks in Advance :)

Best off using the mailing list for this rather than a github issue.

I don't think there's direct support for arbitrary rest calls today, but if you're comfortable extending riemann then I'd suggest looking at how http://riemann.io/api/riemann.pagerduty.html#var-pagerduty is implemented.

Yep, just write a stream like (fn [event] .. ) and use an HTTP library to make your call. For instance:

(require 'clj-http.client :as http)
(where (< 0.9 metric)
  (fn [event]
    (http/get "http://my.service/foo" {:body ... :headers ...}))))
