zabbix-disk-performance

Zabbix template for collecting IO statistics

With this template you can collect different disk statistics.

Installation

To install, copy userparameter_diskstats.conf to /etc/zabbix/zabbix_agentd.d/userparameter_diskstats.conf and lld-disks.py to /var/lib/zabbix/scripts/lld-disks.py. If /var/lib/zabbix/scripts does't exists, create it: sudo mkdir /var/lib/zabbix/scripts -p && sudo chown zabbix:zabbix /var/lib/zabbix -R userparameter_diskstats.conf is user parameters for Zabbix. lld-disks.py is low level discovery script for enumerating disks of your system.

After that restart zabbix-agent sudo service zabbix-agent restart

Go to Zabbix's web interface, Configuration->Templates and import Template Disk Performance.xml. After that you should be able to monitor disk activity for all your disks.

Low level discovery won't list your RAID devices, so some tuning may be required.

Using without User Parameters

Zabbix have standard parameters for monitoring disk io: vfs.dev.read and vfs.dev.write with several types:

• sectors
• operations
• sps
• ops

Template have this values configured, but disabled by default.

Testing

To test that everything work use zabbix_get:

zabbix_get -s 127.0.0.1 -k "custom.vfs.dev.write.sectors[sda]"
