DESCRIPTION
FBScanner can be used to profile database applications, monitor user activity, manage database connections (including client disconnection on both Classic and SuperServer architecture). It’s also ideal for troubleshooting INET errors (INET/inet_error: send errno = 10054), as well as auditing existing applications and performance tuning.

Applications send queries to Firebird and receive results via TCP/IP…

This is exactly what FBScanner does:
You can see and log: - SQL queries (statements,
parameters, plans)- Connections (IP/names,
versions of clients, times)- Users (names, times, etc)- Transactions - Errors and their reasons
(10054, 10038, etc)

…not only see and log, but take full control and manage it
• Filter (allow/deny) connections by IPs/Names
• Identify and kill zombie connections
• Set priorities for Classic instances • Mark and manage everything:– users, connections, applications,
SQLs statements , etc

Tags are COOL!
Tags are special marks set by developer in the SQL source code of applications
Tags help to quickly answer the following (very frequent) questions:
• What program has launched this query? • What is the transaction for this query? • Where is this [very long] query from?

Tags are not only COOL, they are easy!
• Tags allow to assign readable identifiers (names) to Connections, Queries and Transactions. You just need to add these commentaries to the text of SQL:
SELECT COUNT(*) FROM RDB$DATABASE/* FBSCANNER$CON_NAME=My_application;FBSCANNER$TR_NAME=Read_only_transaction_N1;FBSCANNER$ST_NAME=Customers_list_query; */

FBScanner also can identify and log security breaches• Unsuccessful login attempts• 100% logging of SQLs, connections
and other traffic – queries are stored with information
about their connection and transaction
• All transactions are logged, even rolled back

Scenarios
• Let’s quickly walk through the most popular scenarios where FBScanner is used:– General monitoring– Connections’ management– Debug and test applications– Logging
www.ibsurgeon.com
General monitoring•What server is doing? CPU/traffic/queries•Who is connected to this or that database?• Connections life time. Are any “zombies” at server?• Connections activity•What 20% queries create 80% of server workload?
www.ibsurgeon.com
Connections’ management
• Filter and close connections (kill and safe disconnect are supported)• Set priorities for connections (Classic only) – manually and automatically
(rule-based)
www.ibsurgeon.com
Debug and test applications• Error in transaction management– OAT (Oldest Active Transaction). Who lost the transaction?– Named connections, transactions, queries
• Full control– Developer can see queries from own and third-party
applications (closed sourced)– It does not depend on client libraries
• Problem detection– Wrong client library version– Bad queries
www.ibsurgeon.com
Logging• Connections– All information from FBScannerViewer
(database , login, role, IP, PID, etc)
• Transactions– Parameters tpb_nnn– Result (commit or rollback)
• Queries– SQL statement text with/without parameters– Start/end time, CPU Time– Wait time– Plans (extremely useful to find performance bottlenecks!)

Overhead of FBScanner – less than 15% (with 250 connections)
