For several ESX and ESXi servers I'm using the Nagios plugin developped by OP5 called check_esx. It queries the physical host and returns useful information, e.g. CPU, Memory and Network usage. To create rrd-graphics with Nagiosgraph the following map entries need to be done and it will work with your check_esx plugin (note that I renamed it to check_esx3 in my environment):

# Service Type: check_esx3 Disk
# Nagiosgraph regex by Claudio Kuenzler
# Check: check_esx3 -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l vmfs -s $ARG3$ -w $ARG4$ -c $ARG5$
# Output: CHECK_ESX3 OK - GLDSP-ESX03-LD1 - total: 1426.75 GB - used: 467.05 GB (32.74%) - free: 959.70 GB (67.26%)
# Perfdata: 'GLDSP-ESX03-LD1 used Space'=467.05GB;1284.08;1355.41;0.00;1426.75
/output:CHECK_ESX3.*total: (\d+.\d+) GB.*used: (\d+.\d+) GB.*/
and push @s, [esxdisk,
        ['total', GAUGE, $1*1000**3 ],
        ['used', GAUGE, $2*1000**3 ] ];

# Service Type: check_esx3 CPU
# Nagiosgraph regex by Claudio Kuenzler
# Check: check_esx3 -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l cpu -s usage -w $ARG3$ -c $ARG4$
# Output: CHECK_ESX3 OK - cpu usage=7.74 %
# Perfdata: cpu_usage=7.74%;90;95
/output:CHECK_ESX3.*cpu usage=(\d+.\d+) %/
and push @s, [esxcpu,
        ['usage', GAUGE, $1 ] ];

# Service Type: check_esx3 Memory
# Nagiosgraph regex by Claudio Kuenzler
# Check: check_esx3 -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l mem -s usage -w $ARG3$ -c $ARG4$
# Output: CHECK_ESX3 OK - mem usage=44.30 %
# Perfdata: mem_usage=44.30%;90;95
/output:CHECK_ESX3.*mem usage=(\d+.\d+) %/
and push @s, [esxmem,
        ['usage', GAUGE, $1 ] ];

# Service Type: check_esx3 Network
# Nagiosgraph regex by Claudio Kuenzler
# Check: check_esx3 -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l net -s usage -w $ARG3$ -c $ARG4$
# Output: CHECK_ESX3 OK - net usage=271.34 KB/s
# Perfdata: net_usage=271.34KB;40000;60000
/output:CHECK_ESX3.*net usage=(\d+.\d+).*/
and push @s, [esxnet,
        ['usage', GAUGE, $1*1000 ] ];

Add the code above into your nagiosgraph map file (mostly in /etc/nagiosgraph/map or /usr/local/nagiosgraph/etc/map, depends where you installed nagiosgraph). 

And this is how it'll look:

Hi Perera, it looks like the plugin has changed a lot since I used it. The output is completely different now. Maybe you don't even have to add manual entries to the map file, the perfdata part looks pretty straightforward to me:

v3700_VMSAN-C=95.12%;15:;10:

So with a bit of luck it could work with the default map entry. Otherwise you'd have to write a map entry like this:

# Service Type: check_vmware_api.pl Storage
# Nagiosgraph regex by Claudio Kuenzler
# Output: CHECK_VMWARE_API.PL OK - Storages : 'v3700_VMSAN-C'(free)=1440365.00 MB (95.12%)
# Perfdata: v3700_VMSAN-C=95.12%;15:;10:
/perfdata:.*=(\d+.\d+)%;(\d+):;(\d+):/
and push @s, [storage,
['current', GAUGE, $1 ],
['warn', GAUGE, $2 ],
['crit', GAUGE, $3 ]
];

I tried to build the same in my setup but seems graph is not working properly. when I analyse the result of the comment it is not same. Can you please help to correct it. This is the out I get by running /check_vmware_api.pl -H 10.226.2.1 -u root -p holcimesxi -l vmfs -s v3700_VMSAN-C -w "15%:" -c "10%:" command

Output
------
CHECK_VMWARE_API.PL OK - Storages : 'v3700_VMSAN-C'(free)=1440365.00 MB (95.12%) | v3700_VMSAN-C=95.12%;15:;10:

Please help how to build the nagios map entires

In the nagiosgraph map file. You usually find this either in /etc/nagiosgraph/map or /usr/local/nagiosgraph/etc/map - depends where you installed it.
