Hi all, Yet another try to add sysutils/riemann port. May be this time I'll be lucky.
Riemann is an event processor which gets events from various inputs, aggregates/analyses/filters/processes them and sends the results to some output. I'm using it for more than two years for different purposes and found it very useful. For example, I monitor temperature sensors from various devices in the datacenter. Modern devices have many sensors and any temperature fluctuation can indicate fauilure of some of the system's components. Riemann helps to monitor not the absolute values, but the rate of changes. I.e. if the temperature value from any sensor rises two or more times above average for more than 1 degree during 10 minutes, I'll get a notification. It works so well that I can see if the technician enters the room and stays long enough in the hot corridor behind the rack: I'm getting the alert in this case. Some other uses: CPU/load; disk/network IO; filesystem usage monitoring. It can also be used as a homegrown IDS/IPS, like this: if the system keeps getting an increasing number of events from the given IP address, then do something about it (block, tarpit, alert, strike back, etc). -- With best regards, Pavel Korovin
