NAME

       pmfind - find PCP services on the network

SYNOPSIS

       pmfind [-q] [-m mechanism] [-s service] [-r] [-t timeout]

DESCRIPTION

       pmfind  searches  for instances of the specified PCP service being advertised on the network and prints a
       list of URLs corresponding to the services discovered.

       By default pmfind will search for all supported PCP services, however a specific PCP service to  discover
       can be specified using the -s option. Supported services are pmcd(1), pmproxy(1) and pmwebd(1).

       The  -m  option sets the mechanism that pmfind uses when performing service discovery.  By default, or if
       the keyword "all"  is  specified,  every  available  mechanism  will  be  used  (iteratively).  Supported
       mechanisms are:

       avahi  Searches  for  services which are broadcasting using mDNS via avahi-daemon(8).  An optional suffix
              ",timeout=N" may be added to limit the amount of  time  waiting  for  the  avahi-daemon.  N  is  a
              floating  point number specifying the number of seconds to wait. The default is 0.5 seconds.  This
              timeout may also be specified by setting the environment variable AVAHI_DISCOVERY_TIMEOUT  to  the
              desired  number  of  seconds.  If  both are specified, then the value specified in the environment
              variable takes precedence.

       probe=<net-address>/<mask-bits>
              Actively probes the given subnet for the requested PCP service(s).  <net-address> is  an  inet  or
              ipv6 network address and <mask-bits> is the number of bits used to define the subnet. For example,
              192.168.1.0/24   defines  an  8  bit  subnet  consisting  of  the  addresses  192.168.1.0  through
              192.168.1.255.  An optional suffix ",maxThreads=N" may be added to limit  the  number  of  threads
              used  while  probing.  The  default  is  the value of FD_SETSIZE or the number of addresses in the
              subnet, whichever is less.  An optional suffix ",timeout=N" may be added to limit  the  amount  of
              time  waiting  for  each connection attempt. N is a floating point number specifying the number of
              seconds to wait. The default is 20ms.

       The -r option requests that DNS name  resolution  be  attempted  for  the  addresses  of  any  discovered
       services. The default is to display the network addresses of any discovered services.

       The  -t  option  sets  the  maximum  amount of time that pmfind will take before interrupting the service
       discovery. The argument is a floating point number representing the number of seconds before timing  out.
       The default is to take as much time as is needed to complete the process.

       The -q option suppresses all output on the standard output stream.

PCP ENVIRONMENT

       Environment  variables with the prefix PCP_ are used to parameterize the file and directory names used by
       PCP.  On each installation, the file /etc/pcp.conf contains the local values for  these  variables.   The
       $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).

DIAGNOSTICS

       The  value of the exit status from the command is zero when services were successfully located, one if no
       services were found, and two if an error occurred.

       In the event of an error, a message will be generated on standard error that  is  intended  to  be  self-
       explanatory.

SIGNALS

       pmfind  will  interrupt  the  service  discovery  process  when one of the following signals is received:
       SIGHUP, SIGPIPE, SIGINT, SIGTERM, SIGXFSZ, SIGXCPU.  pmfind will report any results which were discovered
       up to point of the interruption.
