====== Output of control commands using the JSON format ======
{{indexmenu_n>11}}

Output in JSON format is provided to simplify the parsing of command output when integrating with external platforms and WEB.
To do that you should specify an additional option:
<code>--outformat json</code>

For the convenience of working with json, we recommend installing the jq utility:
<code>yum install epel-release
yum-config-manager --disable epel
yum --enablerepo epel install jq</code>

**Examples**

Formatted output of the result of the command
<code>fdpi_ctrl list all profile --policing --outformat json|jq .</code>

View usage statistics for different policing profiles
<code>fdpi_ctrl list all --policing --outformat json|jq '.lpolicings[].description.name'|sort|uniq -c</code>

or the same in json format by jq
<code>fdpi_ctrl list all --policing --outformat json|jq  '[{ name: .lpolicings[].description.name, login: .login }] | group_by(.name) | .[] | { name: .[0].name, count: . | length}'</code>

For later use, you can turn this into a bash function
<code>function fdpi_policing_stat() { fdpi_ctrl list all --policing --outformat json|jq  '[{ name: .lpolicings[].description.name, login: .login }] | group_by(.name) | .[] | { name: .[0].name, count: . | length}'; }</code>

and then just call this function from the command line
<code>fdpi_policing_stat</code>

For regular use of functions you can save them in a .bash_profile file.
