We are planning to support as many messaging systems as we can. We will definitely investigate Pulsar. Going to add it to our feature list and make an issue on plumber to support introspection on Pulsar. Cheers!
Good to know that Pulsar is on your roadmap. Also, kudos to see user-land tooling around a common painpoint for teams doing any event processing at scale.
Thank you! We felt the pain point while actively trying to build observability tools in order to debug our messaging systems. We built plumber to standardize some of our internal tools and then decided to open source it to help others who are feeling the pain.
