The SFC project has functionality that can "indirectly" monitor network functions (called Service Functions in SFC). I say indirectly since the monitoring is used for what we call Service Function (SF) scheduling algorithms, which helps us choose which SF to use based on either CPU load, or shortest path.


When we integrated ODL SFC into OPNFV, we didnt use the SF scheduling algorithms but instead delegated that to a VNF manager. Typically, the VNF manager would also monitor the network functions.

In Beryllium, the Armoury project was created to monitor the network load of a network function which could then report overloading situations to a VNF manager. The Armoury project didnt get much traction, and is effectively on hold for now.

The question needs to be asked if it really makes sense for ODL to monitor SFs/Network Functions or if something like a VNF manager should do it instead.

Hi,

Is there any project/plugin in ODL that its purpose is to conduct health checks ?

I’m referring to the health of external machines that run network functions for example (firewalls, load balancers, content filtering, etc.).

Health checks can be pings, load, generic scripts etc.

In a real deployment, will you do those inside ODL? or use an external health tool that will notify status change to the ODL?

Thanks,

Guy Sela
