Trap SNMP events in riemann

What should I do to send snmp traps into riemann server?

Traps... Dunno if anyone has done that yet. Google reports several SNMP pollers though.

@qnick Haven't seen anything like that published, but I suspect you could build a snmp4j trap listener, something like this, and wrap it with a bit of clojure that converts the trap into a Riemann event. The graphite transport has an example of creating and event.

Edit: herark by @c-garcia might be a better starting point for Riemann integration than native snmp4j.

The collectd snmp plugin will emit events on traps (and will also poll if you want)

Other idea: using snmptrapd and syslog-ng

[pyr]

Yes, that would be the most elegant and low-maintenance way.

Ok, thank you. I decide to write python script for redirecting events from snmptrapd to riemann.

#!/usr/bin/env python

import sys
import logging
from riemann_client.transport import UDPTransport
from riemann_client.client import QueuedClient
logging.basicConfig(filename='/tmp/snmp.log', level=logging.INFO)
tags = ["snmp"]
ttl = 120

host = raw_input()
ip = raw_input()

with QueuedClient(UDPTransport("localhost", 5555)) as client:
  for line in sys.stdin:
    logging.debug(line)
    oid , val = line.split(None,1)
    try:
      val = val.strip().strip('"')
      client.event(service = oid, metric_f = float(val), host = host, tags = tags, ttl = ttl)
    except ValueError:
      logging.warn("Cannot convert %s to float", val)
  client.flush()

It seems to work well.

@pyr how do you configure collectd-snmp to listen for traps?

[pyr]

@faxm0dem turns out you can't
