You can see here that "dd" is an example of this behaviour. While it exited successfully, it also wrote non-essential information to its secondary output. You do not see stdout (the primary channel) in the log because "dd" doesn't use it in this case. Cheers, Ondra On 2.3.2016 17:41, paf1@email.cz wrote:

- SUCCESS means the command was successful - <err> is what the command wrote to stderr, which is sometimes useful This is indeed confusing and wrong - there is not need to log stderr of all commands by default. In the case of this dd command, the read latency is reported later in repoStats logs. We will clean this in the future. Nir
