Check snapshots age and number

I tried it on esxi 6.5 nodes and it works successfully.
As per instructions, it is necessary to configure a ssh certificate in order to allow the connection from the nagios server to the esxi nodes.
It only checks if snapshots are present, and it is not possible to filter the checked VMs.

Hi,
I just tried this on VMWare 7.0U1, still working :)

---

I have ESXi 5.5. If i run this script in console it works great. But in nagios it is always OK status, even i have critical value. What can i do, to fix this?

---

btw - the script is also compatible with esxi 5.x

#!/bin/bash
# Author Stefan Nonchev
# Nagios script for checking the number of existing snapshots and how old are these.
# The script should work with any ESXi 5.x
# Installation notes:
# On your nagios server execute:
#
# #sudo nagios
# #ssh-keygen
# copy the public certificate into /etc/ssh/keys-root/authorized_keys on each ESXi host that will be monitored

print_usage() {
echo ""
echo "Usage: $0 [esxi_hostname] [warn] [crit] [snapage]"
echo "where"
echo "- [warn] and [crit] are the allowed numbers of all snapshots (summarized)"
echo "- [snapage] is how old a snapshot is allowed to be (days)"
exit 3
}

dte2=$(date2stamp $2)
diffSec=$((dte2-dte1))
if ((diffSec $4 days ) snapshots on: $vmstr"
exit 2
fi

if [ $total -le $warn ] ; then
echo "OK - $total snapshots found (warn=$warn)"
exit 0
fi

if [ $total -ge $crit ] ; then
echo "CRITICAL - $total snapshots found (crit=$crit)"
exit 2
fi

if [ $total -ge $warn ] ; then
echo "WARN - $total snapshots found (warn=$warn)"
exit 1
fi

Hi, i'm tring to use your plugin but i can't embed my credential on check command, also if i use it from cli on nagios server il stuck on password.
I'm wrong in the syntax?

./check_VM_snapshots 172.17.85.1 10 20 10

thanks
