Dynamic Thresholds Support Copied
Some Service Checks within this Opspack support Dynamic Thresholds for Opsview Enterprise.
Prerequisites Copied
If you intend to use the SMART HDD Status service check, then the host with that device must have smartctl installed and configured for use.
Setup and Configuration Copied
Add the Host Template Copied
Add the OS - Unix Base Host Template to your Opsview Monitor host.

| Variable | Description |
|---|---|
| DISK | Optional. The mount-point for the disk usage statistics, e.g. / or /home |
| SMARTDISK | Optional. The HDD mount-point for the SMART disk statistics, e.g. /dev/sda |
Note
For more information, refer to the documentation on Adding Variables to Hosts.
Note Copied
For the Opsview Linux Agent, in order to run the SMART Service Check + plugin, you need to edit the /etc/sudoers file and add this line at the bottom (on the monitored host):
opsview ALL=NOPASSWD:/usr/sbin/smartctl
For the ITRS Infrastructure Agent, instead see prerequisites at check_smart.
