integer division or modulo by zero

[alexeyshishkin01]

hello, all! I hit the following issue:

[ERROR] 2017-09-03 23:53:22,575 - CFS - catch error: integer division or modulo by zero [INFO] 2017-09-03 23:53:22,575 - CFS - hint: enable debug level to full exception trace [DEBUG] 2017-09-03 23:53:22,575 - CFS - Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/mamonsu/lib/plugin.py", line 140, in _loop self.run(self.sender) File "/usr/lib/python2.7/site-packages/mamonsu/plugins/pgsql/cfs.py", line 63, in run zbx.send('pgsql.cfs.activity[total_compress_ratio]', non_compressed_size / compressed_size) ZeroDivisionError: integer division or modulo by zero

what's wrong with my installation/configuration of mamonsu?

the way I install/initialize mamonsu is the following:

sudo yum install -y python-setuptools sudo rpm -ivh mamonsu-2.2.9-1.el7.centos.noarch.rpm
