Monitor interface traffic every five minutes

[Ajinkya Fotedar]

Hello everyone,

I would like to monitor particular interfaces on our routers and display those on the console, every 5 minutes. Is there a way in PyEz that i can do this.

Something on the lines of the following:

1.

user@router> monitor interface xe-7/1/0 | display xml rpc 

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/13.3R4/junos">

    <message>

        xml rpc equivalent of this command is not available.

    </message>

    <cli>

        <banner>{master}</banner>

    </cli>

</rpc-reply>

or this:

2.

user@router> show interfaces statistics xe-7/1/0 | display xml rpc 

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/13.3R4/junos">

    <rpc>

        <get-interface-information>

                <statistics/>

                <interface-name>xe-7/1/0</interface-name>

        </get-interface-information>

    </rpc>

    <cli>

        <banner>{master}</banner>

    </cli>

</rpc-reply>

Any help appreciated. Thanks!

Hi Ajinkya,

I put together some proof of concept code for you.  Please keep in mind that this is not really production quality as it does not guarantee continuous execution, error handling, the decision to leave the connection to the device open or flapping, etc.

Long term you may want to look at something like Celery http://celery.readthedocs.org/en/latest/userguide/periodic-tasks.html

#!/usr/bin/python

from datetime import datetime

# Schedule library

# http://apscheduler.readthedocs.org/

from apscheduler.schedulers.blocking import BlockingScheduler

# PyEZ

from jnpr.junos import Device

from jnpr.junos.op.phyport import PhyPortStatsTable

sched = BlockingScheduler()

@sched.scheduled_job('interval', minutes=1)

def timed_job():

    dev = Device(host='dev', user='user', passwd='pass')

    dev.open()

    pst = PhyPortStatsTable(dev)    

    pst.get('ge-0/0/0')

    print "{0} - {1}".format(datetime.now(), pst.to_json())

    dev.close()

sched.start()

$python sched.py
