I recently installed Zabbix on a Ubuntu box I had sitting around. It's only monitoring 2 servers but I've noticed that it's continuously smashing the HD with writes. I don't remember Zabbix being this resource heavy when I've used it in the past...

Any ideas on why this is happening and what I can do about it?

Running iotop gives me this:

1710 be/4 mysql       0.00 B/s  102.12 K/s  0.00 %  0.00 % mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306
1723 be/4 mysql       0.00 B/s    0.00 B/s  0.00 %  0.00 % mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld

I'm pretty sure it's Zabbix that's causing all that mysql activity as it's the only thing which uses mysql which is running on the box...
