This looks like a bad hack to me. Why don't you adjust OOMScoreAdjust in the 
system unit files of these services (or
corresponding setting in init scripts) ??

Re: [ansible-project] with_items to get values from a shell cmd output

2020-04-09 Thread Dick Visser 
The result from your grep/awk shell task consists of multiple lines, each
with one PID.
So instead of stdout you should use stdout_lines:
https://docs.ansible.com/ansible/latest/reference_appendices/common_return_values.html#stdout-lines


Also, you are iterating over a list of 1 item, which is incorrect as well.


Also, you're trying to establish something called "os_type" using a shell
task, but that is not necessary - this is already available in the ansible
facts (which you've explicitly gathered).
So just use 'ansible_system' instead.

Also, you declare "become: yes", but also "remote_user: root". That's
double. Either connect as non-root user and only declare "become: yes"
(which implies become_user = root). Or just only declare "remote_user:
root".

Try this:

- hosts: temp
  gather_facts: yes
  remote_user: root
  tasks:
   - name: Adjust OOM to negative so that OOM killer does not kill below
processes
 shell: 'ps -ef|egrep
"sssd|wdmd|portreserve|autofs|automount|ypbind|rpcbind|rpc.statd|rpc.mountd|rpc.idampd|ntpd|lmgrd|Xvnc|vncconfig|irqblance|rpc.rquotad|metric|nscd|crond|snpslmd|
getpwname.pl|mysqld|rsyslogd|xinetd|sendmail|lsf|tigervnc|tightvnc|cfadm"
|egrep -ve "ps|egrep" |awk "{print \$2}"'
 register: oom
 when: ansible_system == 'Linux'
   - debug:  var=oom.stdout
   - name: update the pid
 raw: echo -17 > /proc/{{ item }}/oom_adj
   loop: "{{ oom.stdout_lines }}"

[ansible-project] with_items to get values from a shell cmd output

I got this error for below code - FAILED! => {"msg": "template error while 
templating string: expected token 'end of print statement', got '='. 
String: {{ var=oom.stdout }}"} 

Please suggest , i am trying to get pid from shell cmd & then update it 
with echo
