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:

Total DISK READ: 0.00 B/s | Total DISK WRITE: 431.19 K/s

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...


how many new values per second ? which version of zabbix ? is mysql binlog disabled ?

  • It's Zabbix 1.8.2, mysql binlog is disabled. How do I check the number of new values per sec? – Ganesh Shankar Apr 26 '10 at 8:00

I managed to figure out what was wrong and fix it.

I'd created a test item (to check if my original configuration was working properly) but the test item itself was failing and causing the continuous writes...

Thanks for the help!
