{{DISPLAYTITLE:/proc/user_beancounters}}
The proc filesystem entry showing resource control information is <code>/proc/user_beancounters</code> file. An example content of <code>/proc/user_beancounters</code> is shown below.
the <code>limit</code> for the parameter.
== Units of measurement ==As also discussed in [[{{Main|UBC parameter units]], all values related to parameters withnames starting with <code>num</code> are measured in pieces. Values related to parameterswith names ending with pages are measured in memory pages (memory page is 4 kilobytes onx86 and x86_64 hardware, others may differ). Values related to other parameters are measured in bytes.}}
== Settings ==
General notes about parameters and their barrier and limit settings
are provided in [[UBC parameters]]. Parameters not having limit setting have
[[MAX_ULONGLONG_MAX]] in the corresponding field.

{{Note|It's easier to use [[BC proc entries|the new <code>/proc/bc</code> interface]], i.e. <code>cat /proc/bc/$CTID/resources</code>.}}
If you want to print UBC values for a specific container, the following construct can be helpful
<nowiki>egrep -A23 '^[["${CTID}:space" /proc/user_beancounters</nowiki> Or with headers, though slightly harder to remember:]]+ <nowiki>sed -nr "1,2p;/${CTID}:' /,+23p" /proc/user_beancounters</nowiki>
Here <code>${CTID}</code> is the ID of the container you are interested in.
