When I’m running a service which processes a lot of data, sooner or later I start to wonder: what is the service doing? What data is it processing? This also applies to our event processor Tornado. For the Tornado Engine, the administrator may wonder for example how many events Tornado is receiving, how many actions…

Dynamically Manage Traps from a PowerMe UPS in NetEye’s Tornado

UPSs are critical devices that need particular attention when you’re monitoring them. Most of them are not very performant with respect to SMNP requests you send them. For this reason, passive monitoring via SNMP traps is the best solution. In this way, monitoring doesn’t burden the hardware with useless requests. In this session we’ll look…

Avoid Tornado Rules Repetition with a Map Post-modifier

In this post I’ll describe a concrete use case of the Tornado Map Modifier that will enable us to cover in a single rule many cases in both a user-friendly and performance-friendly way. This feature of Tornado allows us to avoid a common anti-pattern: the repetition of rules with minimal differences. This anti-pattern creates a…

Tornado: Tracing

How can we allow a Tornado administrator to successfully track down the flow of an event through Filters, Rules and Actions of Tornado, when Tornado is processing thousands of events per second?

Automatically Detecting Tornado Anomalies through its Logs

Tornado is an event-driven engine that substitutes the previous engine called Eventhandler. Its use in NetEye is becoming ubiquitous, and this is just the start! One of its main uses in the NetEye ecosystem is to trigger status changes within Icinga (this in turn will usually send emails to stakeholders). However, understanding exactly what is…

In my previous post I showed you how to make your own alerts on NetEye SIEM by using the Elastic Watcher and Alerts and Actions features. But if we work in production environments, what we really need is an alert that can go directly to NetEye’s Monitoring Overview. How can we manage SIEM alerts and…
