Managing HyperFabric
Displaying Status and Statistics

Note that turning on performance statistics gathering will affect the performance of
HyperFabric, by increasing CPU usage and message latency (the time it takes a
message to get from one point to another). It might also decrease the throughput of
data. It is recommended that you do not specify this parameter unless you are trying
to troubleshoot HyperFabric problems.
You must be logged in as root to use this parameter.
• -d specifies that you want to set the level of data displayed to display_level, which
is one of the following:
NET Displays fabric component statistics.
CFG Displays the management daemon (clic_mgmtd)
configuration and statistics data.
VRID Displays the virtual route identifier
information—the VRIDs, IP addresses, switch
hopcounts, and physical routes—for each
HyperFabric adapter in the local node.
ALL Displays all available status data.
• -c displays the statistics of the adapter identified by adapter_ID.
• -n displays statistics for the node identified by nodename.
• -s specifies that you want to get the status of the switch identified by switch_ID
(assigned by clic_init or SAM). Note that this parameter is meaningful only if you
enabled switch management (through the clic_init command).
To determine the switch_ID, run the clic_stat command without specifying any
parameters. This displays each switch_ID known to the system. Look through the
command’s output to find the ID of the switch you are interested in.
• -? displays the online help for clic_stat.
If you do not specify any of the above parameters, the current fabric map is displayed,
showing the last known status of the components.
Examples of clic_stat
Some examples of using clic_stat are shown below.
• Example 1
If the local node is bently7, and you want to enable DLPI driver statistics gathering,
issue this command:
clic_stat -p TCP
The generated output could look like this:
