Hi ,

As per my knowledge Nagios have better documentation go ahead and read it.
command[check_tomcatSession]=@libexecdir@/check_tomcatSession [ -H hostname or IP address ] [ -P port ] [ -u username ] [ -p password ] [ -s session_name ] [ -w warning ] [ -c critical ] [ -V tomcat_version (6 for tomcat pre-7 or 7) ]

DEFAULTS
hostname=localhost
port=8080
username=Administrator
password=password
session_name=
warning=100
critical=400
tomcat_version=6

Did you try this
If session_name is omitted (default) then the total number of sessions is calculated

Hi ,
When I am using following command "/usr/lib64/nagios/plugins/check_tomcatSessions -s 10 -w 100 -c 400 -V 7", output is as follows

Tomcat sessions 10 UNKNOWN: | sessions=

check_tomcatSessions plugin contains code which you find in attachment .This is the plugin which I have downloaded from link
which you have suggested.

what is the output without "-s" option.
OR
You may try the session_name going to this the following URL
http://ip_address: port/manager/list (tomcat v6)
http://ip_address: port/manager/text/list (tomcat v7)
