No logs being generated in case of a masakari service failure

[MoizArif]

While setting up and running Masakari for the first time. Instance monitor failed to start without generating any log files. Running python files for the particular service directly from the code throws out errors on console. There should be a way where such errors are reported directly in instancemonitor.log file even if the service is failing to start.

service masakari-instancemonitor start
Starting masakari-instancemonitor: *

service masakari-instancemonitor status
* masakari-instancemonitor is not running

python /opt/masakari/instancemonitor/masakari_instancemonitor.py

Traceback (most recent call last):
  File "/opt/masakari/instancemonitor/masakari_instancemonitor.py", line 29, in <module>
    import libvirt_eventfilter as evf
  File "/opt/masakari/instancemonitor/libvirt_eventfilter.py", line 29, in <module>

ImportError: No module named httplib2

pip install httplib2
service masakari-instancemonitor start

Result: SUCCESS

* masakari-instancemonitor is running

@MoizArif thank you.
I think we have to fix,
(1) loging
(2) change the rule file to install requirment.txt before setup
