In search of STABLE DB variable to use for determining if a change has been made

Thank you for your response. Unfortunately, that's not what I'm looking for.

My code pulls the DB variable value and compares it to a file called $f5host.lastmod, which contains the variable value returned the last time a change/sync was done. Like this (in perl):

sub modcheck {
 my $lasttimeshitchanged = read_file("/var/f5backup/$f5host.lastmod");  
 $bigip->GET("sys/db/configsync.localconfigtime");
 $jresponse = decode_json $bigip->responseContent();
 my $checkvalue = $jresponse->{"value"};
 if ( $checkvalue > $lasttimeshitchanged ) {
      $shitchanged = 1;
      write_file("/var/f5backup/$f5host.lastmod",$checkvalue);
 }
}

Any time a device-group runs a sync operation, whether automatic or manual, that variable changes. After running checks, the APM module seems to not have an issue, but ASM keeps running an automatic sync which de-stabilizes that variable. I could use ltm.configtime, which is stable on the ASMs, but that wouldn't tell me if an ASM change had occurred, only an LTM change. I can write code to recognize when the ASM module is provisioned and check multiple variables, but I haven't been able to find a matching variable (ex. asm.configtime doesn't exist) that tells me the last time a change was made to the ASM module.

Any ideas?

Sincere thanks in advance.
