1- check_nutanix.pl can monitors many aspects of Nutanix Cluster (Controllers, Hypervisors, Cluster, Disks, VMs, ...)
Requires le Nutanix MIB locally installed
For syntax, check_nutanix.pl --help
2- check_ssh_nutanix_cluster.pl can monitors
a- services on CVMs using 'cluster status' command
b- last alerts using 'ncli alerts ls' command
It requires Net::OpenSSH and Date::Parse perl modules.
For syntax, check_ssh_nutanix_cluster.pl --help.libnet-openssh-perl
Change in 1.1 :
check_nutanix.pl :
- New features to adapt to new Nutanix MIB
- Bug fix for syntax error at ./check_nutanix.pl line 98, near "clusterIOBandwidth"
check_ssh_nutanix_cluster.pl :
- Cleanup of host key to avoid annoying error of

Dears,
That is almost half year, when this plugin is in production monitoring.
Yesterday, monitoring server was found died... halted because ... inodes finished.
# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on

tmpfs 1005525 1 1005524 1% /dev/shm
/dev/sda1 128016 62 127954 1% /boot
yep, that is 13,912,080 millions of inodes used
The problem found:
plugin invokes libnet-openssh-perl library which created files in uesr's (nagos) home directory, which created file for each performed check:
# ls -la /home/nagios/

it took some time to count:

Keep in mind (after integrating).
Plugin itself is excellent!
