Call for `cloudflared` logging feedback

Reaching out from the Cloudflare team about an upcoming change to how cloudflared handles logs. We’d like to get your feedback about how you use these logs and how they could be improved. We’re using this page to collect it, but if you’d prefer to reach out directly, please do so.

Today, cloudflared captures logs and provides them in two channels:

  1. If you invoke cloudflared interactively, from the command-line, the logs are printed in your terminal as a series of time-stamped events.
  2. If you specify a log file storage location, cloudflared writes logs to that destination (this occurs whether cloudflared is run as a service or invoked from the command-line).

We’d like to improve that workflow and have plans to tackle it in two directions:

A simpler UI when invoked interactively

In the first example, those logs become cluttered fast with information that is not entirely useful. We’d like to replace that stream of events with a summary view of your cloudflared process.

A default file storage location

Today, we ask you to specify a destination to write logs, which become a log file. We are considering some alternatives about writing those to a more default location like journald or the Windows event logger.


While we focus on improving those two areas, we’d appreciate your feedback. We have a few short questions - feel free to answer any or all.

  1. When running cloudflared interactively, what summary information would be valuable to know? This could include the data centers connected, the connection status, or other details.
  2. When running cloudflared interactively, do you prefer to view the logs as they are streamed?
  3. Do you have a preferred storage location for writing cloudflared logs beyond specifying a log file location? Would you prefer your operating system log service to a log file on the filesystem?

As always, thank you for your time and for helping make Argo Tunnel better here.

Running cloudflared as service

logfile: /var/log/argo.log
loglevel: info

Logs in /var/log/ are then ingested to LogDNA
