The new year is going to arrive in less than three hours (local time), we don't really celebrate the new year, as our new year has already started in September, we celebrate our holidays according to the "Hebrew Calendar", but the daily life is handled according to the Gregorian Calendar, so I am mentioning that date. The mood here is not a celebration mood, various locations in the universe have their own natural disasters: The east coast of the USA and the Caribbean Islands have Hurricanes, parts of Asia have Tsunamis, the west coast of the USA and some other places have earthquakes, and we in Israel have periods of fightingwith one of our neighbors. Some are viewing it as the natural disaster of the middle east, like hurricanes; however, unlike hurricanes, I strongly believe that human violence can be avoided, but will not get in this Blog into the very complex situation. For those who were asking me about my personal safety -- this time we are (so far) quite far from the combat area, and in general -- I have better feeling of personal safety here than in many other places in the universe.
An interesting comment about my previous posting made by Richard Veryard
Richard referred to the comment I've made about being more productive in a Cafe, and asked whether this is a result of getting less interrupts, and what we can project to event processing in the enterprise level.
I think that this is a good point, actually, one the more marketed benefit of event processing systems are their ability to help not missing any event that requires reaction (I think that the term identifying "threats" and "opportunities" is much over-statement of most detected situations, but will write about it another time), in some cases, the business benefit of event processing system is actually reducing the number of events, and focus the decision makers on the important events.
Some examples:
- In Network Management there is a phenomenon knows as "event storm", e.g. when some network segment is out, many devices send "time-out" alerts, which are just the symptoms of the real problem. What we want is to reduce this event storm to a single event that need to be reacted upon.
- I would like to get alert when my investment portfolio is up by 5% within a single day (as you can see, I am still optimistic). Here I don't care about any of the many raw events about any of my investments, but about the situation defined above.
- Filtering out unnecessary events
- Aggregating multiple events to one
- Report on derived event when some pattern is detected.
