integer division or modulo by zero

hello, all!
I hit the following issue:

[ERROR] 2017-09-03 23:53:22,575 - CFS - catch error: integer division or modulo by zero

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

[alexeyshishkin01]

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

psql --dbname=postgres --username=postgres --port=5433 --host=127.0.0.1 -c "create user mamonsu with superuser"

psql --dbname=mamonsu --username=mamonsu --port=5433 --host=127.0.0.1 -c "create extension pg_wait_sampling"
mamonsu bootstrap --dbname mamonsu --username mamonsu --host 127.0.0.1 --port 5433
mamonsu export template ~/PostgresProEnterprise-template.xml --add-plugins /etc/mamonsu/plugins --template-name PostgresProEnterprise-Linux
mamonsu zabbix template export ~/PostgresProEnterprise-template.xml --url=http://127.0.0.1/zabbix/ --user=Admin --password=zabbix

mamonsu zabbix template id PostgresProEnterprise-Linux
mamonsu zabbix hostgroup create PostgresProEnterprise
mamonsu zabbix host create 'PostgresProEnterprise server' 8 10105 127.0.0.1
sudo cp /etc/mamonsu/agent.conf /etc/mamonsu/agent.conf.ORIG
