Sysctl

[Vino B]

Hi All,

   Request your help, on the below code, i wanted to check whether the sysctl paramater "vm.nr_hugepages" has any numeric value .

 - name: Check whether System Settings are Optimized

    command: sysctl -n {{ item.pname }}

    register: net_param

    failed_when: net_param.stdout != item.value

    with_items:

      - { pname: 'net.core.rmem_max', value: "16777216" }

      - { pname: 'vm.nr_hugepages', value: 'regex[0-9]' }  <==== Issue

    changed_when: false

    ignore_errors: True

From,

Hi All,

Any help is much appreciated.

Why reinventing the wheel, there's already a function for this in jinja... numeric

You probably have to do two different steps... It depends exactly on what you want (perhaps not what you write)
