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.

•-dspecifies 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.

•-cdisplays the statistics of the adapter identified by adapter_ID.

•-ndisplays statistics for the node identified by nodename.

•-sspecifies 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:
