FBScanner: IBSurgeon's tool to solve all types of performance problems with Firebird

FBScanner
MR-machine
for Firebird

1

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

What if we will intercept and analyze SQL traffic?
www.ibsurgeon.com

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)
www.ibsurgeon.com
4

…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
www.ibsurgeon.com

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?
www.ibsurgeon.com
6

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; */
www.ibsurgeon.com

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
9

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
Parameterstpb_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!)
