Try this adaptation of your approach:
Code:
u=u_user
srvc='ps -aef'
patterns="sleep|ABC|abc_xyz_exe|abc_cde|abc.agent.app|ABC abc"
oldIFS=$IFS
for host in $(cat srv.lst)
do
  if ping -c2 -w3 "$host" > /dev/null; then
    echo "Connecting to $host and getting the process list \n"
    pslist=$(ssh $u@$host $srvc)
    IFS=\|
    for pattern in $patterns;
    do
      case $pslist in
        (*"$pattern"*)
          :
        ;;
        (*)
          echo "Service \"$pattern\" is not running"
        ;;
      esac
    done
    IFS=$oldIFS
  else
    echo "$host is not available"
  fi
done

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME
xzgrep - search compressed files for a regular expression SYNOPSIS
xzgrep [grep_options] [-e] pattern file... xzegrep ... xzfgrep ... lzgrep ... lzegrep ... lzfgrep ... DESCRIPTION
xzgrep invokes grep(1) on files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified are passed directly to grep(1). If no file is specified, then standard input is decompressed if necessary and fed to grep(1). When reading from standard input, gzip(1), bzip2(1), and lzop(1) compressed files are not supported. If xzgrep is invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1). The same applies to names lzgrep, lze- grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils. ENVIRONMENT
GREP If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1). SEE ALSO
grep(1), xz(1), gzip(1), bzip2(1), lzop(1), zgrep(1) Tukaani 2011-03-19 XZGREP(1)
