NEWS (original) (raw)

• The package now has its own hex logo.
• Only generate the OpenMetrics format when the (preliminary) OpenMetrics content-type is passed in the Accept header. Otherwise, fall back on the Prometheus format and content-type (#3).
• Pushgateway functions will now stop() for HTTP errors instead of merely issuing a warning. Clients that can tolerate these errors will likely tryCatch() them anyway, sincehttr::RETRY() can fail for other reasons.
• Requests made to Shiny apps that return HTTP 401 will no longer include the rendered metrics anyway.
• The ", \n, and \characters are now escaped in labels and help text, as in the OpenMetrics reference implementation (#1).
• Counter metrics can now be incremented by zero.
• Counter, Gauge, and Histogram metrics can now take an optionalunit parameter. The provided unit must match the one in the name of the metric itself – e.g. areceived_bytes metric must have unit “bytes” (#2).
• Counters and Histograms now have a _created child metric, as per the OpenMetrics draft specification (#2).
