Description Javier Coscia 2018-08-10 13:26:10 UTC 
Description of problem:

When configuring sudolog@info on any Hosted Engine Host, the logs will be flooded, among other messages, with:

~~~
Aug 10 08:30:41 sudo[6278] exec /sbin/service [service vdsmd status]
Aug 10 08:30:41 sudo[6296] exec /sbin/service [service sanlock status]
~~~

If you also have LDAP configured to log this kind events on a remote system, the network traffic will increase, the call is being made every 10 seconds for each HE Host.

systemctl status $service doesn't require sudo privileges, so we should remove the 'sudo' invocation in _check_service 



Version-Release number of selected component (if applicable):

ovirt-hosted-engine-ha-2.2.16-1.el7ev.noarch.rpm

How reproducible:

100%

Steps to Reproduce:
1. Deploy a Self HostedEngine environment
2. Configure sudo to log with INFO (comment out Debug sudo line in /etc/sudo.conf) or have a remote system logging sudo commands
3. Check flood of 'systemctl status $service' in sudo log

Actual results:

'systemctl status $service' where $service is both vdsmd and sanlock, is being executed with sudo privileges

Expected results:

'systemctl status $service' doesn't need additional sudo privileges

Additional info:

We should remove sudo from _check_services in ovirt_hosted_engine_ha/agent/hosted_engine.py
Comment 1 Javier Coscia 2018-08-14 00:18:50 UTC 
Is there a workaround we could share with users in regards to disabling sudo from hosted_engine.py ?

Setting NI on Ido since Simone is OOO.

ok, ovirt-hosted-engine-setup-2.2.28-0.0.master.20180917152606.git1a3b790.el7.noarch
