#!/etc/Tivoli/bin/perl
# tivstat.pl
# Script to watch for critical tivoli processes dying.
#
# Notes:
# 1) Cache keys are forced to lowercase
#	status values of cache hash:
#	no key - this process has never been detected on this endpoint
#	1 - this process is running
#	0 - this process was running but has stopped
# 2) Includes work done by James Boone (see tme10 email forum "postemsg.pl")
# 3) Intended to be run as an lcfd boot_method with its own dependency set:
# on NT,
#  - ntprocinfo.exe (generates a process list on NT - Tivoli supplied)
#  - perl.exe (V4 Tivoli supplied)
#  - tivstat.tecs (data file that has to be created)
# on UNIX,
#  - perl (V4 Tivoli supplied)
#  - tivstat.tecs (data file that has to be created)
#
# V1.0,	Original,	Paul Claridge,	06Jun2001
# V1.1			Paul Claridge,	12Jun2001
#		Added more logic to correctly detect oserv restart
#		Tightened up string matches to avoid bad process matching
# V1.2			Paul Claridge,	13Jun2001
#		Further tightening of string matching to avoid wrong alerts in the
#		case where a process is a substring of another process

# You probably need to review all of these and the %tiv_sev hash!

Tec-o-Bell V 2.1 Make Tivoli Enterprise Console events audible.

- General design: A daemon regulary polls the TEC server for new events. For each of the defined event groups the most recent event of each severity is read. This data is stored in files, one for each event group. A client program regulary reads one of these files. Which one depends on the event group the user is interested in. It checks each severity for a changed date since last access. A sound for the highest changed severity is being played. The Tec-o-Bell parts are very lightweight and do not slow down framework functionality. Event storms do not result in additional workload. Only short polling cycles could result in some reasonable CPU usage. The number of clients is nearly unlimited. Due to the polling mechanism of server daemon and client the alarm sounds are being played with some time delay. The primary goal was to serve many clients with little resource usage. So hearing an alarm one minute late seemed to be even better than not seeing a severe error because another desktop window hides the TEC console. - How to get it: This program is FREE (GPL) for anyone!

Do you want to see TEC events in a web browser? and group this events in a business view tree? and have alarm sounds whenever a new event arrives? This is now available with "WebTEC". It's a tool I developed for our Tivoli environment. And it is now usable FREE (GPL) for anyone! Have a look at http://members.mcnon.com/widi/webtec

Key features:

1. multiple business view trees to a set of event groups

2. http based: on the client side only a standard web browser is needed nearly unlimited number of clients no firewall problems, access even through internet Framework functionality is only used to acknowledge/close events server part is based on Apache and PHP3, two great freeware products

3. event sensitive help documents with index engine

4. fast and easy configuration, event filters based on SQL syntax

5. configurable alarm sounds

6. asynchronous event display, unaffected by event storms

7. free software
