show cli

show cli [mp-safe][not-mp-safe][hit][clear-hit]

Displays debug cli command information

show cli [mp-safe][not-mp-safe][hit][clear-hit]

"show cli" displays the entire debug cli:

abf attach
abf policy
adjacency counters
api trace
app ns
bfd key del
... and so on ...

"show cli mp-safe" displays mp-safe debug CLI commands:

abf policy
create vhost-user
ip container
ip mroute
ip probe-neighbor
ip route
ip scan-neighbor
ip table
ip6 table

"show cli not-mp-safe" displays debug CLI commands
which cause worker thread barrier synchronization

"show cli hit" displays commands which have been executed. Qualify
as desired with "mp-safe" or "not-mp-safe".

"show cli clear-hit" clears the per-command hit counters.

show vlib graphviz

Dump packet processing node graph as a graphviz dotfile

Dump dot files data to draw a graph of all the nodes. If the argument 'filter' is provided, only the active nodes (since the last "clear run" command) are selected and they are scaled and colored according to their utilization. You can choose to filter nodes that are called, nodes that receive vectors or both (default). The 'file' option allows to save data in a temp file.
