           Summary: influxdbBackendListener and mode=StrippedDiskStore
                    problem ?
           Product: JMeter
           Version: Nightly (Please specify date)
          Hardware: PC
            Status: NEW

  Target Milestone: JMETER_5.2

Hello all,

I have started to play with Backend Listener + Influxdb + Grafana.
It's nice but I have finded some strange things :)
(tested with 5.1.1 release + 5.2-SNAPSHOT 450712c)

In all "transaction" entries, there is no "Sent" or "Received" Bytes, I think
it's just not calculated / summed from the requests to the parent sample. So,
when I'm using the "Generate parent sample" option in my scenario (usual for
me), I never have network traffic information into InfluxDB.

I find no informations about "Response code per second" and "Connect times over
time" into the influxdb database, I think it would be a nice addition because
those kind of values are important to analyse stressed platforms.

It seems that the backup listener flow depends of remote batching mode
choosen...

a) mode=StrippedBatch (default)
- I only got one point every 30 seconds for all metrics except "Active Thread".
So "Total Throughput" is not correct because it's value is summed (one dot with
20 req/s every 30 sec).

b) mode=StrippedAsynch
- This one seems ok, I got realtime result for all metrics, and the "total
throughput" is correct with 4 req/s.

c) mode=StrippedDiskStore or mode=DiskStore
- This is the worst, I got NO data in influxdb except start an stop marker,
even the number of active thread is 0 !

I'm using jmeter with mode=StrippedDiskStore frequently to send me listener
result at the end of the test (some jp@gc graphs plugins), so I'm disappointed
that I can't add a backend listener with mode=StrippedDiskStore !

Is there any way to have influxdbBackendListener working correctly (live), and
send the other listener results at the end of the test with
mode=StrippedDiskStore ?

Thanks for any input :)
Pierre

Hello,

I have a last question about Backend Listener :)

-----
- 4 -

From GUI, when I'm remote testing a simpletest.jmx without any Listener, the
Network usage between slave to master is near 0 bytes/s. This is normal because
the slave is just performing the test, and no result data need to be sent to
the master.
Then, when I'm adding one "Backend Listener" (configured to connect to another
influxdb server), I see network usage grow up between slave to master !

I think this should be removed, because the master doesn't care to receive all
the result flow for one "Backend Listener". I mean, it's the slave who is
computing the result with his own "Backend Listener" and send the data to
influxdb no ? if yes, there is no need to send the "SerialisedSampleSender"
data to the master.
