for monitoring java applications website availability, issuing custom commands in servers , in general, monitor applications go general-purpose monitoring solution, pandora fms. i'll try answer questions in order:
- check if websites up, send notifications email otherwise.
doing network check tcp port 80 , parsing 200 ok response.
- easily access or display logs in real-time located in different places on our servers. send emails when exceptions occurred , logged
easy thing log retrieval feature. check out in wiki.
- issue commands , run scripts located on our servers. os of server linux. commands restart tomcat...
i'd suggest using pandora agents in case. quite powerful, yet low resource consumption. allow post-actions if app down, cpu high, or in general terms, anything can measure happens. check out server monitoring more deeply: http://pandorafms.com/monitoring-solutions/server-monitoring/
