| D | histogram.rst | 24 The format of a hist trigger is as follows::
26 hist:keys=<field1[,field2,...]>[:values=<field1[,field2,...]>]
50 key. If a hist trigger is given a name using the 'name' parameter,
60 'hist' triggers add a 'hist' file to each event's subdirectory.
61 Reading the 'hist' file for the event will dump the hash table in
62 its entirety to stdout. If there are multiple hist triggers
99 A typical usage scenario would be the following to enable a hist
102 # echo 'hist:keys=skbaddr.hex:vals=len' > \
105 # cat /sys/kernel/debug/tracing/events/net/netif_rx/hist
107 # echo '!hist:keys=skbaddr.hex:vals=len' > \
