logging: Structured logging reference PR
To convert the existing `gf_msg` to `gf_smsg`:
- Define `_STR` of respective Message ID as below(In `*-messages.h`)
#define PC_MSG_REMOTE_OP_FAILED_STR "remote operation failed."
- Change `gf_msg` to use `gf_smsg`. Convert values into fields and
add any missing fields. Note: `errno` and `error` fields will be
added automatically to log message in case errnum is specified.
Example:
gf_smsg(
this->name, // Name or log domain
GF_LOG_WARNING, // Log Level
rsp.op_errno, // Error number
PC_MSG_REMOTE_OP_FAILED, // Message ID
"path=%s", local->loc.path, // Key Value 1
"gfid=%s", loc_gfid_utoa(&local->loc), // Key Value 2
NULL // Log End
);
Key value pairs formatting Help:
gf_slog(
this->name, // Name or log domain
GF_LOG_WARNING, // Log Level
rsp.op_errno, // Error number
PC_MSG_REMOTE_OP_FAILED, // Message ID
"op=CREATE", // Static Key and Value
"path=%s", local->loc.path, // Format for Value
"brick-%d-status=%s", brkidx, brkstatus, // Use format for key and val
NULL // Log End
);
Before:
[2019-07-03 08:16:18.226819] W [MSGID: 114031] [client-rpc-fops_v2.c \
:2633:client4_0_lookup_cbk] 0-gv3-client-0: remote operation failed. \
Path: / (00000000-0000-0000-0000-000000000001) [Transport endpoint \
is not connected]
After:
[2019-07-29 07:50:15.773765] W [MSGID: 114031] \
[client-rpc-fops_v2.c:2633:client4_0_lookup_cbk] 0-gv1-client-0: \
remote operation failed. [{path=/f1}, \
{gfid=00000000-0000-0000-0000-000000000000}, \
{errno=107}, {error=Transport endpoint is not connected}]
