Subject: [PATCH 0/8] trace-cmd: Allow agent to use networking
Date: Sat, 16 Apr 2022 21:19:50 -0400 [thread overview]
Message-ID: <20220417011958.1013591-1-rostedt@goodmis.org> (raw)
From: "Steven Rostedt (Google)" <rostedt@goodmis.org>
There's no reason for trace-cmd agent not to be able to do the communication
over TCP instead of vsockets. Have trace-cmd record pass in a host name or
IP address (IPv4 or IPv6) to the -A option and if the cid or guest name
fails, then try host name or IP address.
This will fall back to the P2P time sync protocol and recordings from
different hosts can be synchronized.
Also add more debug prints when the --debug option is used. This proved
useful to debugging this code.
Steven Rostedt (Google) (8):
trace-cmd record: Move port_type into instance
trace-cmd library: Add network roles for time sync
trace-cmd record: Allow for ip connections to agents
trace-cmd agent: Allow for ip connections from the agent
trace-cmd library: Create tracecmd_debug() for debug printing
trace-cmd: Add debug prints for network connections
trace-cmd: Add print helpers to show connections
trace-cmd: Override tracecmd_debug() to show thread id
