If your large bank is using IBM Tivoli for monitoring, and many of them do, odds on they will already be using Perl there. Many other monitoring tools make extensive use of Perl too. Have a word with the monitoring team, they may already have dispensation in place to use Perl, or they can weigh in on your side. I work in that area and know a large number of banks around the world are relying on Perl for customised monitoring of critical live systems.
