ProblemSolutionSummaryPros and ConsAdvantages
DisadvantagesFlexibility and simplicity in implementationPoor
authentication mechanism in Nagios Web Server (via httpasswd)Easy
integration with other toolsNagwin can call every command via
shellHttp integration via NRDPLimited number of standard plugins
for windows platform. Most of plugins are for engineering and Unix
environment (host network management)Passive and Active
checksFailures have to be investigated manually Notifications via
email about critic state of service or hostLimited development
needed:java plugin (for calling Selenium, SOAPUI or other tool)php
page for presenting resultsHighly customizable inheritance,
templates, config files etc.Big community around Nagios

ProblemSolutionSummarySummaryObserver is a monitoring framework
for performance and functional tests which aims to monitor
environment from functional point of viewObserver is not another
testing tool so doesnt aim to find defectsProduction environment
tests have to be simple, repeatable and nonintrusiveSet of tools
based on Nagwin (Nagios distribution) which gives possibility to
monitor applications from functional or performance point of view
(sample: Login to application or How fast to login)Completely web
based for end user Easy to integrate and customize
