CEP Uses: message monitoring

The recent InfoQ conference in London had some interesting banking sessions on high volume / low latency (implying event processing). These included Merrill Lynch on monitoring messages, and Betfair on their online betting system. One can be pretty sure there is CEP in production in these organizations; Merrill’s talk was about monitoring messages or events, which seems to be a popular CEP application area (for TIBCO CEP in any case).
Scenarios for “message monitoring” include:In both these cases, we need to monitor the events and use rules (and the state of the entities being monitored) to deduce if all is well or of some complex business event [*1] has occured that requires attention. The CEP engine manages the state and rules and event channels.
Notes:
[1] Talking of business events, there is an ongoing marketing onslaught from IBM promoting “Business Events” for their new CEP acquisition (versus TIBCO BusinessEvents, er, the original-named product). Somehow, this reminds one of the Lord Of The Rings: the searchlight from IBM’s Marketing Tower has swept across the IT plains and stopped at CEP: now the blue hordes are trying to rename CEP for their own (dark?) purposes… .

Scenarios for “message monitoring” include:
- I have some high value events occuring that represent control messages for my internal systems. The value of these messages, and the requirement to be aware of any potential problems immediately, means I must monitor them end-to-end to deduce possible failure (events) in a timely manner. This is a classic “sense and respond” application for CEP.
. - I have some high value events representing the arrival of important documents in my (managed) business process. The value of these documents, and the requirement to be aware of any potential problems immediately, means I must monitor them end-to-end in my workflow to ensure that the appropriate service levels are met (from the document managament, as opposed to process management, perspective). This is a classic “situation awareness” application for CEP.

gvfs
GVFS(7) Conventions and miscellaneous GVFS(7) NAME
gvfs - GIO virtual file system DESCRIPTION
GIO provides a VFS API to GLib applications. It includes a 'local' implementation using POSIX. gvfs provides implementations that go beyond that and allow to access files and storage using many protocols, such as ftp, http, sftp, dav, obexftp, etc. It also provides support for trash folders, for cd burning and for monitoring interesting devices and volumes on the computer. Applications use gvfs indirectly, by means of GIO loading the gvfs module that implements the GIO extension points. The gvfs support for volume monitoring is included in a separate loadable module. The actual gvfs implementation is distributed over a number of processes. None of these are expected to be started from the commandline, except for debugging purposes. Main processes: o gvfsd - the main gvfs daemon o gvfs-fuse-daemon - mounts gvfs as a fuse filesystem o gvfsd-metadata - writes gvfs metadata Volume monitors: o gvfs-udisks2-volume-monitor - a udisks-based volume monitor o gvfs-afc-volume-monitor - a volume monitor for Apple iPhone/iPod Touch devices Mount backends: o gvfsd-afc - mounts iPhone/iPod touch volumes o gvfsd-afp - mounts Apple Filing Protocol volumes o gvfsd-afp-browse - browses Apple Filing Protocol volumes o gvfsd-archive - mounts archive files in various formats o gvfsd-burn - provides a location for burning CDs o gvfsd-cdda - mounts audio CDs o gvfsd-computer - provides computer:// o gvfsd-dav - mounts DAV filesystems o gvfsd-dnssd - browses dnssd o gvfsd-ftp - mounts over FTP o gvfsd-http - mounts over HTTP o gvfsd-localtest - a test backend o gvfsd-network - provides network:// o gvfsd-obexftp - mounts over obexftp o gvfsd-recent - provides recent:// o gvfsd-sftp - mounts over sftp o gvfsd-smb - mounts Windows Shares Filesystem volumes o gvfsd-smb-browse - browses Windows Shares Filesystem volumes o gvfsd-trash - provides trash:// ENVIRONMENT
GIO_USE_VFS If set, specifies the GIO vfs implementation to use. Possible values include 'local' and 'gvfs'. GIO_USE_VOLUME_MONITOR If set, specifies the GIO volume monitor implementation to use. Possible values include 'unix', 'GProxyVolumeMonitorUDisks2', as well as other native volume monitors that are described in the key files in $XDG_DATA_DIRS/gvfs/remote-volume-monitors. FILES
$XDG_DATA_DIRS/gvfs/mounts This directory contains key files describing mount daemons. $XDG_DATA_DIRS/gvfs/remote-volume-monitors This directory contains key files describing remote volume monitors. SEE ALSO
