perfSONAR User Q&A and Other Discussion

[Brian Tierney <>]

Makes sense. I added this request to the issue tracker to make sure we dont forget about it.

We do use owamp for testing between our toolkit nodes (mesh config).
However, sometimes its useful to setup a pingER test when doing customer troubleshooting since normally a customer will not have an owamp responder in their network. Its really more of a nice-to-have feature for us. It would be awesome if this can be incorporated in a future release.

Thanks!

Jeremy:

Sorry, but no, there is still no way to plot pinger loss.

Is owamp testing not an option in your environment?

We are working on a new plot tool for the next release, and should be able to
add ping loss to that tool.

        Hi Jeremy,

        You're right, the loss is not plotted. I'll put an issue in our issue
        tracker. Our owamp graphs show packet loss, and I confused the two.
        Thanks for bringing it up.

            (Ping Latency) graphs?

            I tried the advice of setting packet size to 1000 in the PingER test
            but it
            doesn't make a different. The graph still shows nothing when there is
            confirmed
            packet loss.

            Perhaps I can illustrate the issue better with a screenshot. I setup
            a PingER
            test to a target host and let it run for a while. I then disabled
            ICMP on the
            host and left it off for about 30 mins (100% ping loss) between 15:53
            and 16:23.
            I then re-enabled ping on the host and waited about 10 more mins and
            then pulled
            up the Ping Latency graph for "12 hours". The below image is the
            result:

            https://dl.dropbox.com/u/__1810709/workstuff/pingER%20no%__20loss%20stats.jpg

            <https://dl.dropbox.com/u/1810709/workstuff/pingER%20no%20loss%20stats.jpg>

            See how at about 15:53 when I disabled ping on the target host, the
            graph
            basically has no data until about 16:23 when I re-enabled ping on the
            host. If
            it were working correctly, I would expect there would be plots for
            100% packet
            loss between 15:53 and 16:23. All this graph shows me is there is no
            data during
            that time period.

            When I manually query the pingerMA database on that toolkit host, I
            see plenty
            of results where lossPercent is not 0 so I'm assuming something is
            broken with
            the process that is actually generating the graph.

            I have tired this on two different 3.2.2 PsToolkit hosts too and I
            get the exact
            same results on both.

                Hi Jeremy,

                Packet loss will be listed to the right of the graph. Try
                increasing the size of the test packets to 1000 and let me know if
                that helps.

                    Subject: [perf-node-users] How do you view packet loss in PingER
                    (Ping Latency) graphs?

                    I setup a PingER test on a pSToolkit 3.2.2 box yesterday to
                    temporarily monitor
                    a customer connection by pinging the router on the far end
                    of the
                    circuit. I
                    know there is intermittent packet loss on this circuit from time
                    to
                    time but
                    when I click on the "Ping Latency" menu in the toolkit and
                    generate a
                    Graph for
                    this host for the last 24hrs, it doesn't show the packet loss on
                    the
                    graph. In
                    fact, the graph legend at the top only shows "Min Delay",
                    "Median
                    Delay", "Mean
                    Delay", and "Max Delay" line colors. There is nothing to show
                    loss.

                    I have verified there are test results that contain packet
                    loss in
                    the database.
                    If I run this SQL query:
                    select * from data_201209 where lossPercent!=0
                    it returns 1110 rows.

                    Is there something I need to do to enable packet loss to show on
                    the
                    PingER Ping
                    Latency graphs? I'm not seeing anything in the PingER
                    documentation
                    related to this.

                    FYI, my PingER test is setup like so:

                    Test Parameters
                    Description     ping
                    Time Between Tests (seconds)    60
                    Packets Sent Per Test   30
                    Time Between Packets (seconds)  1
                    Size Of Test Packets    500
