awk if condition help
Hi, I need little help with awk's if condition statement. I have following code:
Code:
$ ssh myRemotehost 'ps ww -fu tomcat ' | awk ' { if ($1 == "tomcat") print "tomcat (pid " $2 ") is running... "; else print "tomcat stopped or dead" }'

Prints: 

tomcat stopped or dead
tomcat (pid 12345) is running...

if I do the below command, it prints correctly :

Code:
$ ssh myRemotehost 'ps ww -fu tomcat ' | awk ' /tomcat/ { if ($1 == "tomcat") print "tomcat (pid " $2 ") is running... "; else print "tomcat stopped or dead" }'

Prints: 
tomcat (pid 12345) is running...

But the problem is when the tomcat is not detected by the ps command, i do not see any output where in I would like to see that "tomcat stopped or dead"

Can someone please help me refine this.

Thanks in advance.
