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.

certmonger_selinux(8)					     SELinux Policy certmonger					     certmonger_selinux(8)

NAME
certmonger_selinux - Security Enhanced Linux Policy for the certmonger processes DESCRIPTION
Security-Enhanced Linux secures the certmonger processes via flexible mandatory access control. The certmonger processes execute with the certmonger_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep certmonger_t ENTRYPOINTS
The certmonger_t SELinux type can be entered via the certmonger_exec_t file type. The default entrypoint paths for the certmonger_t domain are the following: /usr/sbin/certmonger PROCESS TYPES
SELinux defines process types (domains) for each process running on the system You can see the context of a process using the -Z option to ps Policy governs the access confined processes have to files. SELinux certmonger policy is very flexible allowing users to setup their cert- monger processes in as secure a method as possible. The following process types are defined for certmonger: certmonger_unconfined_t, certmonger_t Note: semanage permissive -a certmonger_t can be used to make the process type certmonger_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. BOOLEANS
SELinux policy is customizable based on least access required. certmonger policy is extremely flexible and has several booleans that allow you to manipulate the policy and run certmonger with the tightest access possible. If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo- gin_nsswitch_use_ldap boolean.

Disabled by default. setsebool -P nis_enabled 1 If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default. setsebool -P nscd_use_shm 1 NSSWITCH DOMAIN

The SELinux process type certmonger_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions. auth_cache_t /var/cache/coolkey(/.*)? cert_t /etc/pki(/.*)? /etc/ssl(/.*)? /etc/httpd/alias(/.*)? /usr/share/ssl/certs(/.*)? /usr/share/ssl/private(/.*)? /var/named/chroot/etc/pki(/.*)? /usr/share/ca-certificates(/.*)? /usr/share/pki/ca-certificates(/.*)? /usr/share/pki/ca-trust-source(/.*)? certmonger_var_lib_t /var/lib/certmonger(/.*)? certmonger_var_run_t /var/run/certmonger.* cluster_conf_t /etc/cluster(/.*)? cluster_var_lib_t /var/lib/pcsd(/.*)? /var/lib/cluster(/.*)? /var/lib/openais(/.*)? /var/lib/pengine(/.*)? /var/lib/corosync(/.*)? /usr/lib/heartbeat(/.*)? /var/lib/heartbeat(/.*)? /var/lib/pacemaker(/.*)? cluster_var_run_t /var/run/crm(/.*)? /var/run/cman_.* /var/run/rsctmp(/.*)? /var/run/aisexec.* /var/run/heartbeat(/.*)? /var/run/cpglockd.pid /var/run/corosync.pid /var/run/rgmanager.pid /var/run/cluster/rgmanager.sk dirsrv_config_t /etc/dirsrv(/.*)? home_cert_t /root/.pki(/.*)? /root/.cert(/.*)? /home/[^/]*/.kde/share/apps/networkmanagement/certificates(/.*)? /home/[^/]*/.pki(/.*)? /home/[^/]*/.cert(/.*)? ipa_var_lib_t /var/lib/ipa(/.*)? pki_tomcat_cert_t /var/lib/pki-ca/alias(/.*)? /var/lib/pki-kra/alias(/.*)? /var/lib/pki-tks/alias(/.*)? /var/lib/pki-ocsp/alias(/.*)? /etc/pki/pki-tomcat/alias(/.*)? /var/lib/ipa/pki-ca/publish(/.*)? root_t / /initrd systemd_passwd_var_run_t /var/run/systemd/ask-password(/.*)? /var/run/systemd/ask-password-block(/.*)? FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type. You can see the context of a file using the -Z option to ls Policy governs the access confined processes have to these files. SELinux certmonger policy is very flexible allowing users to setup their certmonger processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the certmonger, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk. semanage fcontext -a -t certmonger_exec_t '/srv/certmonger/content(/.*)?' restorecon -R -v /srv/mycertmonger_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for certmonger: certmonger_exec_t - Set files with the certmonger_exec_t type, if you want to transition an executable to the certmonger_t domain. certmonger_initrc_exec_t - Set files with the certmonger_initrc_exec_t type, if you want to transition an executable to the certmonger_initrc_t domain. certmonger_unconfined_exec_t - Set files with the certmonger_unconfined_exec_t type, if you want to transition an executable to the certmonger_unconfined_t domain. certmonger_var_lib_t - Set files with the certmonger_var_lib_t type, if you want to store the certmonger files under the /var/lib directory. certmonger_var_run_t - Set files with the certmonger_var_run_t type, if you want to store the certmonger files under the /run or /var/run directory. Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. COMMANDS
semanage fcontext can also be used to manipulate default file context mappings. semanage permissive can also be used to manipulate whether or not a process type is permissive. semanage module can also be used to enable/disable/install/remove policy modules. semanage boolean can also be used to manipulate the booleans system-config-selinux is a GUI tool available to customize SELinux policy settings.
