Ubuntu Manpage: lbcdclient - Query a remote lbcd daemon for system load

NAME

       lbcdclient - Query a remote lbcd daemon for system load

SYNOPSIS

       lbcdclient [-2] [-p port] [-s service[,service ...]]
           [-t timeout] host

DESCRIPTION

lbcdclient sends a query packet to a remote lbcd server and prints the results. The
result output will look something like this:

PROTOCOL 3

MACHINE STATUS:
l1 = 16 (0.16)
l5 = 5 (0.05)
l15 = 6 (0.06)
current_time = 1387677198 (2013-12-21 17:53:18)
boot_time = 1386357534 (2013-12-06 11:18:54)
user_mtime = 1387250916 (2013-12-16 19:28:36)
tot_users = 12
uniq_users = 1
on_console = false
tmp_full = 8%
tmpdir_full = 8%

SERVICES (1):
default (0): weight 368, increment 200

"l1", "l5", and "l15" are the one-minute, five-minute, and fifteen-minute load averages,
times 100, as integers. The conventional load averages, as seen with uptime, are shown on
the right.

"current_time" is the current system time in seconds since epoch. "boot_time" is the time
of the last system boot. "user_mtime" is the time information about logged-in users was
last modified. A translation into a date and time is given on the right.

"tot_users" is the total number of logged-in users, and "uniq_users" is the number of
unique logged-in users. "on_console" will be "true" if a user is logged into the console
and "false" otherwise.

"tmp_full" is the percentage of space used in the system /tmp directory and "tmpdir_full"
full is the percentage used in the system /var/tmp directory.

Finally, for protocol version three queries (the default), the last lines give information
for each service queried, using the extended service response for the version three packet
format. For each service, its name, sequence number in the reply, current weight, and
current increment are given.

If the -2 option is used, lbcdclient will send a version two packet instead, and the
returned results will not include the extended services output.

OPTIONS

       --v2, -2
           Send a version two protocol packet instead of a version three packet.  Version two
           doesn't support the separate service weights.

       -m, --man, --manual
           Print out this documentation (which is done simply by feeding the script to "perldoc
           -t").

       --port=port, -p port
           Send the query to port instead of the default of 4330.

       --service=service, -s service,[service ...]
           Request information for the specified service names.  This option can be given
           multiple times to request information about multiple services.  The services can also
           be specified as a comma-separated list, or a combination of multiple options and
           comma-separated lists.

       --timeout=timeout, -t timeout
           Use a timeout of timeout seconds instead of the default of 10 seconds.

EXAMPLES

       Send a version three query to www.example.com and print the results:

           lbcdclient www.example.com

       Send a version two query to foo.example.org on port 14330, asking for information about
       the "smtp" and "http" services in addition to the default service, with a timeout of five
       seconds.

           lbcdclient -2 -p 14330 -t 5 -s smtp -s http foo.example.org
