I think you want the status of instances of all/different applications... so you can take an array which stores the name of different applns whose instance's status you want to check and for each application you can run that command i mentioned earlier... it will be something like this...
Code:
application={"app1","app2"} #array with app names
#start of for loop
#if statement with condition to check status
#in if condn grep will be like this -> | grep ^${application[i]} i.e. i th element of appln
#end of if
#end of for
Kindly bear with the syntax... please refer to man for correct one...

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
