Hi,

Using ```journalctl -o json-pretty```, you will see other entries in each log.

Thanks,

主旨: [phosphor-host-ipmid] Questions about IPMI (OEM) command development 
 
Hi all,

I have studied "phosphor-host-ipmid" package for a couple of weeks and got understanding that it has implemented some mandatory and optional commands already. And I also knew that I'm able to leverage "intel-ipmi-oem" package to get more command handlers. But there're some questions raised in my mind, I hope someone could give me some suggestions.
1. What's the normal development procedure in case I want to make our own OEM commands? I mean do you guys encourage me to create a new "xxx-ipmi-oem" package or to leverage "intel-ipmi-oem" and then add our own commands in it?
2. I for now added "intel-ipmi-oem" package only for using its "<Chassis>:<Set Front Panel Enables>" command because I figured out the same command in the "phosphor-host-ipmid" is not able to match the d-bus interface in the "x86-power-control". I'm not sure if I will need other commands in the "intel-ipmi-oem", but what if I don't need other commands, how to remove them? to use the whitelist mechanism?
3. Is it okay to add more than 1 xxx-ipmi-ome packages? If yes, how to manage the whitelist between these 2 OEM packages?
4. Am I able to use "intel-ipmi-oem" on a platform that is using AMD CPU?
5. How to print the "entry("SENDER=%s", sender.c_str())" parts? I mean I for now can print out "Set up ipmi context" string after following the instruction listed in "https://github.com/openbmc/openbmc/wiki/Debugging-OpenBMC#enabling-application-debug", but I don't see "SENDER=" when I executed "journalctl -t ipmid" command.
6. 
6. log<level::DEBUG>("Set up ipmi context", entry("SENDER=%s", sender.c_str()), 
                      entry("NETFN=0x%X", netFn), entry("LUN=0x%X", lun),
                      entry("CMD=0x%X", cmd), entry("CHANNEL=%u", channel),
                      entry("USERID=%u", userId),
                      entry("SESSIONID=0x%X", sessionId),
                      entry("PRIVILEGE=%u", static_cast<uint8_t>(privilege)),
                      entry("RQSA=%x", rqSA));


Thank you.
