-h--help
Displays usage information and exits.
-v--version
Prints gkrellmd version and exits.
-V--verbose
Prints connection progress.
-u,--update-hzf
Sets the data update frequency in samples per second for the server. This is independent of and
should be less than the gkrellm client update rate. The rate can be from 1 to 10 and should be
lower to minimize network traffic. A value of not much more than 1/2 the client update rate is
best where it is not important to minimize network traffic.
-m,--max-clientsN
Sets the maximum number of simultaneous clients allowed to connect to the server.
-A,--addressserver_address
Use server_address for the network connection.
-P,--portserver_port
Use server_port for the network connection.
-a,--allow-hosthostname
Specify hosts which are allowed to connect. Multiple allow-host arguments may be given. If no
hosts are specified on the command line or in a gkrellmd.conf file, then all hosts are allowed to
connect. The hostname argument may be a text name or an IPv4 or IPv6 dotted notation. For IPv4,
the simple subnet pattern x.y.z.* may be used. Also, if hostname is the keyword ALL then all
hosts are allowed. This option is additive and specified hosts will be added to the hostnames
listed in gkrellmd.conf files unless the --clear-hosts option is given first.
-p,--pluginname
For plugin development convenience, load and enable the command line specified plugin to avoid
repeated install steps in the development cycle. See the README from the gkrellm demo5 for more
information on gkrellmd plugin development. Requires at least gkrellmd version 2.2.0.
-pe,--plugin-enablename
Specify an installed plugin to enable (this is probably more convenient to specify in a
gkrellmd.conf file). Requires at least gkrellmd version 2.2.0.
-plist Output a list of plugins which are installed and available to enable and exit. Requires at least
gkrellmd version 2.2.0.
-plog Output a log of the plugin install process. When requesting a log, the --detach option will have
no effect. Requires at least gkrellmd version 2.2.0.
-l,--logfilepath
Enable sending error and debugging messages to a log file.
--syslog
Enable sending logging messages to the syslog file.
-c,--clear-hosts
Clears the current list of allowed hosts. Use this before any --allow-host arguments if you want
command line allowed hosts to override and not be additive to those specified in gkrellmd.conf
files.
-d,--detach
Runs gkrellmd in the background and detaches from the terminal.
-U,--userusername
Changes user to username after startup. Useful if you want to run gkrellmd as root, but set it to
run with another privileges; typically as the nobody user.
-G,--groupgroupname
Changes group to groupname after startup.
--pidfilepath
Create a PID file for the running gkrellmd. Typically, path would be /var/run/gkrellmd.pid.
Default is no PID file.
--inet-intervalseconds
The Internet monitor defaults to reading TCP connections once per second. However, for Linux SMP
kernels where reading /proc/net/tcp causes high cpu usage, the inet-interval may be set to 1-20
seconds to slow down /proc/net/tcp reads. Or set it to 0 to totally disable the Internet monitor.
Requires at least gkrellmd version 2.1.8.
--io-timeoutseconds
Configure gkrellm clients to disconnect from a gkrellmd server if there is an io-timeout interval
where the client receives no input from the server. Use this for conditions where gkrellmd may be
ungracefully terminated such that socket connections are not closed. Minimum is 2 (less than 2
for no I/O disconnecting and is the default). Requires at least 2.1.8 versions of both gkrellmd
and gkrellm.
--reconnect-timeoutseconds
Configure gkrellm clients to attempt automatic reconnects to a gkrellmd server every reconnect-timeout seconds after a disconnected state is detected. Disconnected states are created by normal
gkrellmd shutdowns or by an expiring io-timeout. Minimum is 2 (less than 2 for no automatic
reconnecting and is the default). Requires at least 2.1.8 versions of both gkrellmd and gkrellm.
--mailboxmbox_path
Check the server side mailbox mbox_path and send mail counts to connected gkrellm clients.
Mailbox types may be mbox, Maildir, and MH mail. Requires at least 2.1.11 versions of both
gkrellmd and gkrellm.
--net-timernet_interface
Configure gkrellmd to send the connect time for a network interface to all clients to be displayed
in the client gkrellm timer button monitor display. If this is done, the client gkrellm timer
button can still execute commands on the client, but the button will not affect the timer display.
If you want the client timer button to execute commands on the server, your timer button commands
can use ssh. So set this if your server box has say a ppp0 or ippp0 connection and you want to
monitor its connect time. Requires at least 2.2.7 versions of both gkrellmd and gkrellm.
--mbmon-portport_number
If the mbmon daemon is running when gkrellmd is started, gkrellmd will connect to mbmon using the
given port_number and send mbmon sensor data to connected gkrellm clients. The mbmon daemon
should have been started using the same port number like so: mbmon-r-Pport_number
