For grep, the nicest test wrapper is the -q, as it is terse, grep can stop at the first hit and just exit 0 else exit 1 at eof, with no additional interpreting commands like -ge:
OP is interested in "Running", not "Running as Standby". Your solution would yield a false positive. Yes, using
will work without giving a false positive, but certain Unices don't follow the POSIX switch for "quiet", using -s instead.

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.
