Hi,
You could also do a SNMPWALK on the hrSWInstalledName table
(1.3.6.1.2.1.25.6.3) and extract the latest installed kernel version by
doing some regex work.

Current as in installed, or current as in available?
We wrote this a while ago to see if the most recently installed kernel
is the bootable kernel:
#!/bin/bash
#
# Check if current kernel is being used.
#
GRUBBY=/sbin/grubby
GREP=/bin/grep
UNAME=/bin/uname
OUTPUT="Current kernel running."
EXIT_VAL=0
if $GRUBBY --default-kernel | $GREP -vq $($UNAME -r); then
OUTPUT="Kernel updated, reboot required."
EXIT_VAL=1
fi
echo $OUTPUT
exit $EXIT_VAL
But as Daniel said, a trivial plugin it's NRPE calling the two-line
routine:
#!/bin/bash
/bin/uname -r
exit $?
Or using SNMP:
define command {
command_name return_kernel_version
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -o
SNMPv2-MIB::sysDescr.0 -P 2c -C public
}
The choice of what to use is yours.

I haven't seen one, but would be trivial to write one. You looking to
see the rpm -q kernel output or something like uname -a?

Does anyone know of or have a plugin that will display the current
