Re: Hash of Hashes, referencing, dereferencing and Net::SNMP

Well, the problem is here:

$results_table->{$$group}}->{$$site_name} = {
                                                sysobjid => "unknown",
                                                snmp_status => "NOT OK
+",
                                            };

Contrary to what might be convenient, you are assigning a whole new hash reference (and leaving the old hash orphaned and subject to garbage collection).

You will have to break the statement down into two parts:

results_table->{$$group}}->{$$site_name}->{sysobjid}="unknown;
results_table->{$$group}}->{$$site_name}->{snmp_status}="NOT OK";

You will have to break the statement down into two parts Another approach would be using a hash slice: `my $site = results_table->{$$group}->{$$site_name}; # for convenience @{ $site }{("sysobjid", "snmp_status")} = ("unknown", "NOT OK");` [download]	[reply] [d/l]
