<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello Michael, Thanks for your help. Nagios is able to monitor my url however if i change the response message in my url then nagios do not generate any warning or error. My settings are as per your suggestion. Command: define command{ command_name check_http2 command_line $USER1$/check_http -I $HOSTADDRESS$ $ARG1$ } Service: define service{ use generic-service ; Name of service template to use host_name jvnag service_description [INDIA] MMPPlus Sync URL Check is_volatile 0 check_period 24x7 max_check_attempts 3 normal_check_interval 5 retry_check_interval 1 contact_groups mvas-admins,india-support,mma-PM notification_interval 20 notification_period 24x7 notification_options w,u,c,r,f check_command check_http2!172.22.65.51!'-u /MMPPlus/RequestReceiverServlet?mobileNo=919200000000&moid=0000&operator=TATA&circle=DELHI&content=TAPAN&shortCode=542428 -w 3 -c 5 -r ^TAPAN$ -t 7' register 1 } Current message which should be checked by above service is TAPAN however response which is coming from url is TAPAN_1. It should thorough some error or waring in nagios. If i am firing below mentioned command in command line then it is working as expected. Command: ./check_http -H 172.22.65.51 -p 80 -u "/MMPPlus/RequestReceiverServlet?mobileNo=919200000000&moid=0000&operator=TATA&circle=DELHI&content=TAPAN&shortCode=542428" -w 3 -c 5 -r ^TAPAN$ -t 7 Response: HTTP CRITICAL - pattern not found|time=0.072334s;3.000000;5.000000;0.000000 size=174B;;;0 Why it is not working in nagios, i have no idea. Please suggest.

Below are what my config files are, modified to do what I think you are trying to do: This is the standard check_http command in /usr/local/nagios/etc/objects/commands.cfg : # 'check_http' command definition define command{ command_name check_http command_line $USER1$/check_http -I $HOSTADDRESS$ $ARG1$ } the -I checks by IP, and $ARG1$ accepts everything after the second ! as an argument. So this is what the config check would be: YourHostNameHere.cfg: define service{ use generic-service host_name YourHostNameHere service_description YourNameForThisSiteHere check_command check_http!172.22.65.51!'-u /MMPPlus/RequestReceiverServlet?mobileNo=919200000000&moid=0000&operator=TATA&circle=DELHI&content=TAPAN&shortCode=542428 -w 3 -c 5 -s TAPAN -t 7' } -Mike </div> -----Inline Attachment Follows----- <div class="plainMail">------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
