exit status 1

Here's some information that may help.

mysql.inq

check service mysql with hostname localhost, port 3306, username root, socket /tmp/mysql.sock
if memory:rss > 1g then alert
if mysql:Queries > 5/sec then alert
if mysql:Seconds_Behind_Master > 3 then alert

mysql version: 5.7.24
os version: Ubuntu 16.04
installed by: apt-get install inspeqtor ./inspeqtor_2.0.0-1_amd64.deb

I'm not an expert in mysql, but I tried to run show status; in mysql and found no field like "Slave_running". I wonder how can I fix it, or what can I do about it.

Thanks in advance. :P
