I have configured IPSLA udp-jitter on an ASR9k that I am also monitoring via LibreNMS. I am able to see that it detects udp-jitter IPSLA graphs, but it is missing some information. Based on #3550, it seems as if the IOS-XR platform is reading different OID’s for One Way Latency and Jitter. I don’t see ICPIF being monitored at all based on the ipsla output from the IOS-XR OS (likely that it’s not supported under IOS-XR? I didn’t look too much into it).
Here is the output I have for a udp-jitter IP SLA instance:

From #3550, I am able to see jitter values from the snmpwalk:
$ snmpwalk -c community -v2c node .1.3.6.1.4.1.9.9.42.1.3.5.1.64
iso.3.6.1.4.1.9.9.42.1.3.5.1.64.26.401509614 = Gauge32: 1

iso.3.6.1.4.1.9.9.42.1.3.5.1.63.28.401869614 = Gauge32: 2
$
But with that, I am not seeing any values graphed. Nor is the poller.php showing any values as well (snippet of poller.php for the cisco-sla module):

I did notice that the One Way latency OID’s for the XR appears to be the following:
