Add mprocs-with-logging.yaml configuration that logs all service output to /tmp/ directory while maintaining the standard mprocs TUI experience. This enables developers to: - Use mprocs terminal UI for monitoring services interactively - Allow AI coding assistants to read service logs from /tmp/ files - Debug issues by reviewing persistent log files Usage: bin/start --custom bin/mprocs-with-logging.yaml Log files are written to /tmp/posthog-*.log for each service. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Update log file naming to match mprocs process names exactly for better clarity when debugging with AI coding assistants. Examples: - temporal-worker-general-purpose -> posthog-temporal-worker-general-purpose.log - cyclotron-janitor -> posthog-cyclotron-janitor.log - embedding-worker -> posthog-embedding-worker.log 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Closing in favor of #39771 which is on a PostHog branch instead of a fork branch, making it easier for teammates to check out and test. |

Problem
Developers working with AI coding assistants need access to service logs for debugging, but the standard mprocs TUI doesn't persist logs to files that AI tools can read.
I found this sort of broke my flywheel with
claudeor other code assistant tools. Ideally i want those tools to be able to "see" everything i see in the mprocs TUI.Changes
Added
bin/mprocs-with-logging.yaml- an alternative mprocs configuration that:/tmp/posthog-*.logfiles usingteeUsage:
If merged then i will also make a PR to update the handbook to mention this new optional way to run with /tmp/ logging too.
How did you test this code?
Tested locally by:
bin/start --custom bin/mprocs-with-logging.yaml/tmp/directoryChangelog: (features only) Is this feature complete?
No - this is a developer tooling improvement, not a user-facing feature.
Examples
For example i can have
claudenow actually "see" the mprocs logs for each process such that it can justtailandgrepthe corresponding log files in my/tmp/dir:
