Message-ID: <88be2564-c5cf-58f5-b35c-d61e1db504de@chandergovind.org> Date: Wed, 12 Jul 2023 10:39:54 +0530 From: Chander Govindarajan <mail@...ndergovind.org> To: Stephen Hemminger <stephen@...workplumber.org> Cc: netdev@...r.kernel.org Subject: Re: [PATCH iproute2] misc/ifstat: ignore json_output when run using "-d" Hi, So, this does solve the problem correctly, in the sense: 1. First you should start ifstat in daemon mode (without -j, with the patch, it will anyway be ignored) 2. Then, you can run ifstat in normal or in json mode; where it will connect to the daemon, get back results and then print it in the required format (table or json). So, this patch only ensures that the communication between the daemon and other instances happen correctly (not in json). PS: in the process of testing this, I figured out a bug in the -j mode, I will submit a separate patch. :-) Regards, Chander On 7/12/23 02:00, Stephen Hemminger wrote: > On Mon, 10 Jul 2023 16:15:22 +0530 > Chander Govindarajan <mail@...ndergovind.org> wrote: > >> If ifstat is run with a command like: >> ifstat -d 5 -j >> >> subsequent commands (with or without the "-j" flag) fail with: >> Aborted (core dumped) >> >> Unsets json_ouput when using the "-d" flag.
