Starting with the next release (3.9.2) the head check will display additional information next to the name of the node, such as the model, serial number, DataONTAP version as well as the uptime in days. This way one can see these details directly in the monitoring system without having to connect via ssh.

Example:

$ ./check_netapp_pro.pl Head -H sim91  -o health
NETAPP_PRO HEAD OK - 1 head checked
sim91-01 SIMBOX, ser. 4082368-50-7, NetApp Release 9.1, uptime=2.5d: healthy (is-node-healthy: true)
