OK

All the existing sensor are « user defined » this means that you can create a 
sensor providing your RTT/jitter and packet loss.
However, this assumes that these indicators are available and visible from 
RARE/freeRtr via a cli command.

It is planned to couple sensor logic with SNMP transport so that SNMP poller 
can fetch sensor KPI <—> SNMP OID

However this does not change your problem. If the indicator is not visible 
from the control plane then
wether you use SNMP or Prometheus, you won’t be able to retrieve it.

Now, depending on the cli output related the indicator, it might not be « 
parsable ».

In that case, we might have to adjust the CLI output so that it can be 
"prometheus friendly" 

Look at the example here from grafana.com/dashboard: 
https://grafana.com/grafana/dashboards/13153-rare-freerouter-interfaces-bytes/

The logic here is to launch _ANY_ possible CLI command and indicate freeRtr 
to how to craft an indicator ready to be expert by prometheus agent.
For bytes you have then the command:
show interface hwsumm

Which gives the output:

AMS0001#show interface hwsumm
interface  state  tx        rx        drop
sdn1       up     18697381  38294274  0
sdn1.10    up     0         12411969  0
sdn1.20    up     0         12402503  0

sdn3       up     25208927  56863177  0
sdn3.101   up     0         446688    0
sdn3.102   up     0         9671957   0
sdn3.20    up     0         0         0
sdn3.2503  up     0         13768237  0
sdn3.30    up     0         0         0
sdn3.3068  up     0         8459343   0
sdn3.472   up     3994560   5100060   0

I’ll let you dissect the logic of the sensor definition and you’ll understand 
how hardware counters are made available for Prometheus server.

Can you please indicate me which command you plan to use for packet 
loss/jitter/rtt ?

All the best,
Frederic
