In this post we start to list different event sources for CEP applications. I will start with a broad classification, following the probe architecture by
IBM’s NetCool OMNIbus, provide examples, expand and elaborate adding market data feeds, and other event sources that come to mind.
We will expand the list based on comments. Also, we might find it necessary to reclassify the top level sources at some point in the future:
- Devices as Event Sources
- Routers, hubs, switches, and similar network or telecommunication devices
- Network appliances designed for alerting, like a firewall, sniffer or an IDS
- Sensors and sensor networks including RFID readers
- Log Files as Event Sources
- Application log files including syslog ()
- Other flat file event logs
- Databases as Event Sources
- Change (insert, update, or delete) to a row of the source table events
- Events captured in real time during the transaction
- Data Feeds as Event Sources
- Market data feeds
- News feeds (RSS / Atom)
- Other feeds from feed handlers
- Message-Oriented Middleware (MOM) as Event Sources
Please comment to add more event sources.* This list is by no means complete, it is just a beginning.* I’ll update as time permits.
