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

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

Language switch Server, IFX instance selection Appearance & Usage

Managed Informix instances Total number of the IFX instances

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...

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

Global report example

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

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

Example: Temporary tables

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 Backup reports (global) - which instances have not been archived today?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?

Example: Disk space usage (global report)

Example: Backup report (global)
