new bundle for killing processes about evolve_cfengine_freelib HOT 7 OPEN

This is just an example. we use this to klll user processes that consume to much resources on our login nodes. This code must be run on compute nodes.

bundle agent sara_user_consume_resources(minutes, memory, exclude)
{
    processes:
        any::
            ".*"
                comment         => "Kill processes that use to much resources",
                signals         => { "term", "kill"},
                action          => sara_action,
                process_select  => sara_user_consume_resources_select("$(minutes)", "$(memory)", @(exclude));
}

##
# Kill processes that uses too much cpu time or memory and exclude
# important users
#
body process_select sara_user_consume_resources_select(minutes, memory, owners)
{
    command        => "ssh.*|scp.*|rsync.*|cp.*|mv.*|tar.*|gzip.*|bzip2.*";
    process_owner   => { @(owners) };
    ##
    # Bug in ps parsing minutes are seconds. so use the hour field for minutes
    # ttime_range     => irange(accumulated(0,0,0,"$(minutes)",0,0), accumulated(1,0,0,0,0,0));
    ttime_range     => irange(accumulated(0,0,0,0,"$(minutes)",0), accumulated(1,0,0,0,0,0));
    #
    rsize           => irange("$(memory)", 'inf');
    process_result  => "(ttime|rsize).!(process_owner|command)";
}

@basvandervlies Is there a bug report for that time parsing problem?

from evolve_cfengine_freelib.

@neilhwatson this is fixed a long time ago. I must remove this statement. There is a bug report and pull request:

• cfengine/core#747

from evolve_cfengine_freelib.

@basvandervlies I think this bug is still true or the verbose output is off:
snmp 2728 1 0 Aug22 ? 00:02:19 /usr/sbin/snmpd

verbose: P: Container path : '/default/main/processes/'/usr/sbin/snmpd.:'[0]' verbose: P: verbose: P: Comment: Set kill class if count too high verbose: P: ......................................................... verbose: verbose: Selection filter matched counter range 'TIME/TIME' = '00:02:19' in [60,999999999] (= 139 secs)

Ok, i have the source for 3.6 and check it against the 3.7 version
