Response to old thread and referencing my new thread…
“[j-nsp] telemetry analytics - mx960 - npu packet rate concerns”
My JTI/OpenNTI systems seems to be continuing to run nicely. I use it when I
really need to know some details.
In the new thread I mentioned above, I was curious about my CGNat MS-MPC-128G
resource utilization and starting digging around in those sensor agent and
their data I’ve been receiving in my telem station.
I’ll copy and paste from that other thread for convienience.
Using my JTI/Chronograf/Grafana web interface I'm trying to understand some of
the telemetry analytics data I'm seeing coming from what appears to be the
sensor resource of my MX960 corresponding to
/junos/system/linecard/npu/utilization/ .. The field seen on chronograf that
I'm watching is "npu_util_stats.packets.rate"
When using the Chronograf data explorer and picking one MX960 and a certain
_seq number (0-14 , I don't know what these are) I'm seeing some significant
drops in the graph during peak time (approx. 7 - 10 p.m.) watching
"npu_util_stats.packets.rate" with mean function (as opposed to median, count,
min, max, etc, etc). In other words, the graph shows a typical ramp-up
approaching peak times, and ramp-down during the late night hours..
But about a week ago, I started seeing dramatic drops/sags in the graph during
those 7-10 p.m. hours.
I'd like to try to figure out what those drops are related to. I'm wondering if
this is the MS-MPC-128G npu's in-use for my cgnat.. I've been loading it up
quite a bit lately with thousands more subscribers behind it, and am trying to
watch how it scales. and if I have any reason for concerns regarding resource
load, etc.
If you unicast email me, I’ll send you screen shots of my telem graphs that are
giving me concern and the sensor agent strings that I’m looking at.
Thanks y’all

Guys,
I wanted to follow up and see how things are going with JTI?
Also, it has been brought to my attention that OpenNMS supports JTI. I was not
aware of that, so I figured I would share with others:

Yes Niall, lets stay in touch.
Thanks Tom, I’ll have to look at Panoptes
