Wow! This is really cool! I would love to use this at my workplace. I had a small problem, though: it seems the clients don't keep very much data.
For example, I filtered based on an expression that matched about 1-2 lines per second. The lines appeared, but disappeared almost as quickly. I suspect there is some small client-side buffer that I'm overrunning almost instantly; the log stream I used produces about 500 lines per second. Is this too much for the tool? Can I tune it to work with that load?
