Helper and debugging scripts for the Virtio-forwarder are located in
/usr/lib[64]/virtio-forwarder/.
Here are pointers to using some of the more useful one, from the docs:
- virtioforwarder_stats.py: Gathers statistics (including rate stats) from running relay instances.
- virtioforwarder_core_pinner.py: Manually pin relay instances to CPUs at runtime. Uses the same syntax asmthe environment file, that is, -virtio-cpu=RN:Ci,Cj. Run without arguments to get the current relay to CPUmapping. Note that the mappings may be overridden by the load balancer if it is also running. The same is true for mappings provided in the configuration file.
- virtioforwarder_monitor_load.py: Provides a bar-like representation of the current load on worker CPUs. Useful to monitor the work of the load balancer.
System logs can be viewed by running
journalctl -u virtio-forwarder -u vio4wd_core_scheduler on
systemd-enabled systems.
Syslog provides the same information on older systems.
Hope this helps....

fileutil::multi(n) file utilities fileutil::multi(n)
__________________________________________________________________________________________________________________________________________________
NAME
fileutil::multi - Multi-file operation, scatter/gather, standard object
SYNOPSIS
package require Tcl 8.4
package require fileutil::multi ?0.1?
package require fileutil::multi::op ?0.1?
package require wip ?1.0?
::fileutil::multi ?word...?
_________________________________________________________________
DESCRIPTION
This package provides a single command to perform actions on multiple files selected by glob patterns. It is a thin layer over the package
fileutil::multi::op which provides objects for the same. This package simply creates a single such object and directs all file commands to
it.
At the core is a domain specific language allowing the easy specification of multi-file copy and/or move and/or deletion operations. Alter-
nate names would be scatter/gather processor, or maybe even assembler. For the detailed specification of this language, and examples,
please see the documention for the package fileutil::multi::op.
PUBLIC API
The main command of the package is:
::fileutil::multi ?word...?
This command interprets the specified words as file commands to execute. See the section FILE API of the documentation for the pack-
age fileutil::multi::op for the set of acceptable commands, their syntax, and semantics.
The result of the command is the result generated by the last file command it executed.
BUGS, IDEAS, FEEDBACK
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category fileutil
of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for
either package and/or documentation.
