From: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> These patches implement a tool that can be used to read and write the sysfs files, with subcommands! The following subcommands are implemented: rpcctl client rpcctl client show rpcctl switch rpcctl switch set rpcctl switch show rpcctl xprt rpcctl xprt remove rpcctl xprt set rpcctl xprt show So you can print out information about every switch with: anna@client ~ % rpcctl switch switch-0: xprts 1, active 1, queue 0 xprt-0: local, /var/run/gssproxy.sock [main] switch-1: xprts 1, active 1, queue 0 xprt-1: local, /var/run/rpcbind.sock [main] switch-2: xprts 1, active 1, queue 0 xprt-2: tcp, 192.168.111.1 [main] switch-3: xprts 4, active 4, queue 0 xprt-3: tcp, 192.168.111.188 [main] xprt-4: tcp, 192.168.111.188 xprt-5: tcp, 192.168.111.188 xprt-6: tcp, 192.168.111.188 And information about each xprt: anna@client ~ % rpcctl xprt xprt-0: local, /var/run/gssproxy.sock, port 0, state <CONNECTED,BOUND>, main Source: (einval), port 0, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-1: local, /var/run/rpcbind.sock, port 0, state <CONNECTED,BOUND>, main Source: (einval), port 0, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-2: tcp, 192.168.111.1, port 2049, state <CONNECTED,BOUND>, main Source: 192.168.111.222, port 959, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-3: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>, main Source: 192.168.111.222, port 921, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-5: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 671, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt-6: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 934, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 You can use the `set` subcommand to change the dstaddr of individual xprts: anna@client ~ % sudo rpcctl xprt show xprt-4 xprt-4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 anna@client ~ % sudo rpcctl xprt set xprt-4 dstaddr server2.nowheycreamery.com xprt-4: tcp, 192.168.111.186, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 Or for changing the dstaddr of all xprts attached to a switch: anna@client % rpcctl switch show switch-3 switch-3: xprts 4, active 4, queue 0 xprt 3: tcp, 192.168.111.188 [main] xprt 4: tcp, 192.168.111.188 xprt 5: tcp, 192.168.111.188 xprt 6: tcp, 192.168.111.188 anna@client % sudo rpcctl switch set switch-3 dstaddr server2.nowheycreamery.vm switch-3: xprts 4, active 4, queue 0 xprt 2: tcp, 192.168.111.186 [main] xprt 3: tcp, 192.168.111.186 xprt 5: tcp, 192.168.111.186 xprt 6: tcp, 192.168.111.186 Changes in v8: - Improved exception handling when running commands - Completely rework argument and command parsing to be more like ip-link - Completely rewrite the man page to reflect the new argument scheme and add examples - Only call socket.gethostbyname() once when changing the dstaddr of an RPC switch Thoughts? Anna Anna Schumaker (9): rpcctl: Add a rpcctl.py tool rpcctl: Add a command for printing xprt switch information rpcctl: Add a command for printing individual xprts rpcctl: Add a command for printing rpc client information rpcctl: Add a command for changing xprt dstaddr rpcctl: Add a command for changing xprt switch dstaddrs rpcctl: Add a command for changing xprt state rpcctl: Add a man page rpcctl: Add installation to the Makefile configure.ac | 1 + tools/Makefile.am | 2 +- tools/rpcctl/Makefile.am | 13 ++ tools/rpcctl/rpcctl.man | 67 ++++++++++ tools/rpcctl/rpcctl.py | 255 +++++++++++++++++++++++++++++++++++++++ 5 files changed, 337 insertions(+), 1 deletion(-) create mode 100644 tools/rpcctl/Makefile.am create mode 100644 tools/rpcctl/rpcctl.man create mode 100755 tools/rpcctl/rpcctl.py -- 2.35.1
