The following is a demonstration of the anonpgpid.d script,
 
 
 Here we run it on a system that is implementing memory caps using the
 resource capping daemon, "rcapd",
 
    # anonpgpid.d
    Tracing... Hit Ctrl-C to end.
    ^C
       PID CMD              D BYTES
      6215 bash             R 8192
      6215 bash             W 126976
      5809 rcapd            R 245760
      6222 memleak.pl       R 974848
      6222 memleak.pl       W 3055616
 
 The "memleak.pl" process consumes memory, and we can see above that it has
 encountered both reads and writes to the physical swap device - it is being
 paged out. A bash shell was also effected (which was in the same project that
 rcapd was monitoring). 
 
 
 
 The following is an ordinary system that is very low on memory,
 
    # anonpgpid.d
    Tracing... Hit Ctrl-C to end.
    ^C
       PID CMD              D BYTES
     18885 sendmail         R 4096
     18600 automountd       R 4096
         1 init             R 4096
      2456 inetd            R 8192
     18546 nscd             R 8192
      2400 bash             R 12288
       217 utmpd            R 28672
       221 ttymon           R 32768
       210 sac              R 36864
     18777 snmpd            R 49152
     18440 init             R 49152
        89 nscd             R 61440
       318 syslogd          R 73728
       487 snmpd            R 81920
      2453 inetd            R 102400
       165 in.routed        R 131072
       294 automountd       R 135168
       215 inetd            R 135168
       187 rpcbind          R 204800
        86 kcfd             R 290816
         7 svc.startd       R 1015808
         9 svc.configd      R 1478656
         2 pageout          W 23453696
 
 The "pageout" process is responsible for writing all the anonymous memory
 pages to the physical swap device, and we can see from the above that it 
 has written 23 Mb. When processes access anonymous memory that has been
 swapped out, a major fault occurs and the memory is paged back in; in this
 case we can trace the process that was effected, and from the above we can
 see that several processes have been effected by the memory pressure.
 The most is "svc.configd", which needed to page back in 1.4 Mb of anonymous
 memory. 
 
 
 
 Sometimes anonpgpid.d doesn't help too much. Here we only have pageouts
 to the physical swap device and no pageins,
 
    # anonpgpid.d
    ^C
       PID CMD              D BYTES
         2 pageout          W 61083648
 
 Only pageout is identified.
