Extended ping function - Githubissues

iris-connect / eps

Our endpoint system (eps) that manages and secures the communication between different actors in the IRIS connect ecosystem. Think of it as a distributed service mesh router as well as a decentralized message broker. Still evolving, use with caution.

Extended ping function #11

Closed lucky-lusa closed 3 years ago

To give actuators an overview of the other clients available in the system and their connectivity status, we should extend the _ping function.

The following requirements would be important

_ping not only for individual clients, but for a permission group (e.g. app provider). The return value could then be an array of the respective stati
record the eps version in the status
in case of error not only a timeout or the hint that the request could not be delivered should be returned. it would be good if the error could be specified (no entry in sd, connection refused, timeout,...) to simplify debugging.

I have extended the ping function and improved the error messages generated by the message broker. Implementing a broadcast function seems quite complex and error-prone so I have opted to leave this to the client for now. I have implemented a _directory function instead that enables clients to e.g. retrieve all service directory entries for a given group, which should make it easy to subsequently generate _ping requests for all members of the group. Let me know if there's anything else that's missing.
