Subject: [PATCH iproute2-next v2 1/1] police: Add support for json output
Date: Thu, 3 Jun 2021 10:33:45 +0300 [thread overview]
Message-ID: <20210603073345.1479732-1-roid@nvidia.com> (raw)
Change to use the print wrappers instead of fprintf().
This is example output of the options part before this commit:
"options": {
"handle": 1,
"in_hw": true,
"actions": [ {
"order": 1 police 0x2 ,
"control_action": {
"type": "drop"
},
"control_action": {
"type": "continue"
}overhead 0b linklayer unspec
ref 1 bind 1
,
"used_hw_stats": [ "delayed" ]
} ]
}
This is the output of the same dump with this commit:
"options": {
"handle": 1,
"in_hw": true,
"actions": [ {
"order": 1,
"kind": "police",
"index": 2,
"control_action": {
"type": "drop"
},
"control_action": {
"type": "continue"
},
"overhead": 0,
"linklayer": "unspec",
"ref": 1,
"bind": 1,
"used_hw_stats": [ "delayed" ]
} ]
}

Notes:
v2
- fix json output to match correctly the other actions
i.e. output the action name in key 'kind' and unsigned for the index
