Ruby Agent 2.4.21 is out with a bug fix, a new configuration option, and a debug option
App & Background Integration Installation
As reported on Issue #228, if
scout_apm is disabled on a node via the configuration
monitor = false, we don't intend to install any instruments, but a few snuck in anyway.
Since the rest of the agent isn't running, they (slowly but steadily) built up recorded info, but didn't purge it, causing a slow memory leak that became clear over the course of a week or two. We've stopped the offending instruments from installing themselves when Scout is disabled.
New Option: collectremoteip
Our Rails instruments capture a few bits of useful information for each request as Context, and displays that in traces. A few customers with higher privacy concerns asked for a way to prevent end-user IP addresses from being captured.
The default behavior hasn't changed, but now you can disable IP capture by setting
collect_remote_ip = false
Debug Flag: compress_payload
Fun fact - Ruby's string
"false" evaluates to
true in an if statement. Due to this fact, we have a series of conversion functions to turn strings into the correct types. This comes up mostly in ENV variable configuration, since everything arrives as a string. The change in 2.4.21 adds the
compress_payload option to that listing of conversions.
As far as the exact flag, you won't need the
compress_payload setting in your application. It's for debug and development purposes while we are working on our ingest pipeline.
