Introducing Traptweet: An SNMP to Twitter Gateway

I had this idea a little while ago: an SNMP to Twitter gateway. It seemed like an obvious fit: Twitter is all about status updates, and that’s basically all an SNMP Trap is.

So this afternoon I hacked up a little Python script to do it:

# A silly proof of concept SNMP Trap to Twitter gateway
# This scripts listens for SNMP Traps and tweets
# some of the information.
#
# Needs the following Python libraries:
#
# easy_install libsnmp
# easy_install twitter

from libsnmp import v2
from twitter import Twitter

LOGIN = "traptweet-user"
PASSWORD = "MYPASSWORD"

tw = Twitter(LOGIN, PASSWORD)

def sendTweet(trapListener, msg):
    """
    Called when the trapListener recieves an SNMP trap.
    We extract the trap information and send it as a tweet.
    """
    pdu = msg.data

    for varbind in pdu.varBindList:
        tweet = "Trap from %s: %s[%s]: %s %s" % ( str(pdu.agentAddr),
                                                pdu.genericTrap.enum(),
                                                str(pdu.specificTrap),
                                                varbind.objectID,
                                                varbind.objectValue)
        #print "tweet [%d]: %s" % (len(tweet), tweet)
        tw.statuses.update(status=tweet)
        pass

trapListener = v2.SNMP(('0.0.0.0', 162), trapCallback=sendTweet)
trapListener.run()

Which looks like this:
