Subject: Manage Solaris 10 processes (a working example)

For all of you using zones and CF3 on Solaris this helps to identify a process
running on your current zone and excludes children zones when run in a global
so you don't accidentally kill 20 processes that you didn't mean to. :)
------PUT WHEREVER YOU NEED TO UP OR DOWN A SERVICE-----
bundle agent whatever
{
methods:
# Up example..
"any" usebundle =>
up_process("/var/cfengine3/bin/cf-serverd","start_cfserverd"),
comment => "Check that cf-serverd is running";
# Down example..
"any" usebundle =>
down_process("/usr/local/sbin/proftpd","stop_proftpd"),
comment => "Make sure proftpd is not running for all hosts";
}
------PUT IN YOUR COMMON LIBRARY------
# CFEngine doesn't handle zones properly so this is my workaround
# NOTE: This means we can't use any of the process_* commands
# Each bundle below should accomodate our various needs but feel free to create
another one
# if you need something more.
# Bundle type is common so we can set global classes for restarts, etc.
# If you don't need a global class then use bundle agent instead
# NOTE: common bundles that set classes complain with the following error only
if on CF3 3.0.4, 3.0.5p1 fixed this bug
# !! Class identifier contains illegal characters
# NOTE: variables are limited to 8192 characters so on a busy/large system a
normal ps -efZ will cause CF3 to exit.. :(
# Bundle to check if a process is running
# $setclass is created ONLY if the process is NOT running
bundle common up_process(process,setclass)
