Standalone agent 0.0.31

Changed

• Fix disk usage returning a Vec with no entries on Alpine Linux when the df --local command fails.
• Log a warning when no mountpoints are found to report the disk usage metrics. This scenario shouldn't happen (it should log an error, message about skipping a mountpoint or log the disk usage). Log a warning to detect if this issue really occurs.
• Improve extraction of OpenTelemetry span details from the Requests library, by using the HTTP method, scheme, host and port as the event name. This improves grouping in the "Slow API requests" performance panel.
• Remove extra HTTP attributes from Django root spans.
• Remove route tag from HTTP server spans. Since the span will already have the route attribute as part of its name, the tag is redundant.
• Filter more disk mountpoints for disk usage and disk IO stats. This helps reduce noise in the host metrics by focussing on more important mountpoints. Any mountpoint containing /etc/hostname, /etc/hosts, /etc/resolv.conf, /snap/ or /proc/ is ignored.
• Make the debug log message for OpenTelemetry spans from libraries we don't automatically recognize more clear. Mention the span id and the instrumentation library.

Fixed

• Fix missing error metrics for the error rate and error count graphs in some scenarios, like with Koa apps.
• Fix an issue where the method tag extracted from an incoming HTTP request span would be overriden with the method used for an outgoing HTTP request span.
• Support disk usage reporting (using df) on Alpine Linux. This host metric would report an error on Alpine Linux.
• When a disk mountpoint has no inodes usage percentage, skip the mountpoint, and report the inodes information successfully for the inodes that do have an inodes usage percentage.
• Fix an issue where queries containing a MySQL leading type indicator would only be partially sanitised.

This release can be installed through our standalone agent packages and as a Docker image.
