6 Web-based monitoring tool Unique features - covers wide range of Informix versions - provides clear information fast and effectively - provides on-demand reports - understandable for non-Informix people - combined with internal systems (Alerts, CMDB) On-Line and statistical data Developed internally DBA Intranet - introduction

7 Monitoring - instant access to the Informix instance Global reports - across many instances Retention of historical data - also provides history-based reports Functionality

8 Language switch Server, IFX instance selection Appearance & Usage

9 Managed Informix instances Total number of the IFX instances

10 Web BrowserHTTP ServerPERL CGI scripts Administration server Remote IFX instance (hostname+onconfig) SQL to sysmaster, syscatalogs Remote shell (ssh, rsh) Administration IFX instance trusted against the remote IFX instance for the informix user Behind the scenes...

11 What information do we have? Global data - across Informix instances Some data periodically scanned, and cached in the administration database Example: Tblspace report sorted by remaining extents Informix-instance specific Direct information from the selected instance, not cached Example:Buffer pools

12 Global report example

13 Overview of all buffer pools Tblspace name Listing the contents of the buffer pools Instance-specific report example

14 PERL + CGI + DBI modules Dynamical Menu User based menu permissions Access logging Multilingual Development & application structure

15 DB admin - full access Guest - restricted access no administration allowed User-based menu permissions

16 Database size Link to the database scheme... next slide Examples: Database info

17 Example: Database scheme

18 Link to the content of the dbspace Example: Dbspace - chunk info

19 Performance monitoring Sessions Locks Tblspace statistics Temporary tables

20 Example: Sessions - CPU

21 Example: Sessions - SQL

22 Example: Sessions - activity

23 Example: Lock info

24 Example: Tblspace statistics

25 Example: Temporary tables

26 Other useful functions Disk space usage (global report) - which is the biggest instance? - which dbspace has run out of free space? Backup reports (global) - which instances have not been archived today? Logical logs consumption (instance specific) - is the log capacity sufficient?

27 Example: Disk space usage (global report)

28 Example: Backup report (global)

29 Example: Logical logs consumption (instance specific) Xmas 37 GB trs/day24 GB trs/day

30 ... and other functions like reports concerning Oracle instances powered by an Informix database:

31 Single-location access to all Informix instances Wide range of IDS versions supported On-Line and statistical data On-demand reports Combined with internal systems No costs for software, only internal development Summary

32 Future development Application and service-related reports Enhancement of the front-end

33 Live demonstration Database info Dbspace, chunk info Performance monitoring - Sessions, locks, stats, temporary tables Disk space usage (global report) Tblspace report (global)
