[j-nsp] JunOS Telemetry

Strange. It works for me. Maybe a bug or a limitation with your version ? 

Did you try to force SDN-telemetry restart ?

Hmm, I'm not seeing any sensors there

start shell pfe network fpc2

RMPC platform (1200Mhz QorIQ P2020 processor, 3584MB memory, 512KB flash)

NGMPC2(MX-testlab-re0 vty)# show agent sensors

Total number of SENSOR = 0

I've just seen this on the documentation page:  "Junos Telemetry Interface was introduced in Junos OS Release 15.1F3 on MX Series routers"
https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/junos-telemetry-interface-configuring.html

I wonder if it is because I'm running 15.1R4?  It's odd that the telemetry commands are available though....

Ok. 

Could you check at PFE level if sensors are well instanced ? 

start shell pfe network fpcX
show agent sensors

ex. 
show agent sensors

Hi David

It seems to be running:

show system processes extensive | match agentd
20980 root        1  20    0   717M  5584K select  0   0:05   0.00% agentd
20997 root        1  24    0   720M  4468K select  3   0:00   0.00% stats-agentd

Polling is a large number because the value is measured in nano seconds:

{master}[edit services analytics sensor test-sensor] testlab at MXtestlab# set polling-interval ?
Possible completions:
  <polling-interval>   Define sensor polling interval in nano secs (nanoseconds)

So I'm polling every 0.1 seconds.

Simarly, reporting-rate under export-profile is measured in milliseconds, so I'm reporting every second.

Hello

Does agent is running ?

show system processes extensive | match agentd
26812 root          3  20    0   735M 13136K nanslp  1   0:15   0.00% agentd

You could try to restart process :

restart SDN-Telemetry immediately

I see your polling interval is very high David

I've just started investigating using the Juniper telemetry interface for analytics on MX routers, but I'm having some problems getting it running.

I'm using the Juniper Open NTI collector, which is up and running (default config, no changes made whatsoever), however it never receives any data, as confirmed by a tcpdump on the box.

My setup is thus:

testlab at MXtestlab # run show version
Hostname: MXtestlab
Model: mx240
Junos: 15.1R4-S2.1

sensor test-sensor {
    server-name open-nti;
    export-name test-telemetry;
    polling-interval 100000000;
    resource /junos/system/linecard/interface/;
}
streaming-server open-nti {
    remote-address 10.100.0.127;
    remote-port 50000;
}
export-profile test-telemetry {
    local-address 10.100.0.96;
    local-port 30010;
    reporting-rate 1000;
    format gpb;
    transport udp;
}

The problem I see is that "show agent sensors" never reports a sensor:
testlab at MXtestlab# run show agent sensors

{master}[edit services analytics]

I've read over the Juniper docs and can't see anything obvious that I'm missing, however I'm sure it is something simple.

If anyone has any idea's I'd love to hear them!

TIA
