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....

curl_multi_add_handle(3)					  libcurl Manual					  curl_multi_add_handle(3)

NAME
curl_multi_add_handle - add an easy handle to a multi session SYNOPSIS
#include <curl/curl.h> CURLMcode curl_multi_add_handle(CURLM *multi_handle, CURL *easy_handle); DESCRIPTION
Adds a standard easy handle to the multi stack. This function call will make this multi_handle control the specified easy_handle. Further- more, libcurl now initiates the connection associated with the specified easy_handle. When an easy handle has been added to a multi stack, you can not and you must not use curl_easy_perform(3) on that handle! If the easy handle is not set to use a shared (CURLOPT_SHARE) or global DNS cache (CURLOPT_DNS_USE_GLOBAL_CACHE), it will be made to use the DNS cache that is shared between all easy handles within the multi handle when curl_multi_add_handle(3) is called. The easy handle will remain added until you remove it again with curl_multi_remove_handle(3). You should remove the easy handle from the multi stack before you terminate first the easy handle and then the multi handle: 1 - curl_multi_remove_handle(3) 2 - curl_easy_cleanup(3) 3 - curl_multi_cleanup(3) RETURN VALUE
CURLMcode type, general libcurl multi interface error code. SEE ALSO
curl_multi_cleanup(3),curl_multi_init(3) libcurl 7.9.5 4 March 2002 curl_multi_add_handle(3)
