Network monitoring without alerting is like having a clock without any hands. In the previous post, Eric discussed setting up a monitoring strategy, and in it we scraped the surface of network alerting. In this post we dive into alerting more deeply.
Alerting comes in many forms. In the previous post, we discussed how metrics can be set with thresholds to create alerts. This is the most basic level of alerting. CPU alerts are set at 90% of utilization. Disk usage alerts are set to 95% of utilization. There are at least two drawbacks with this level of alerting.
First, by alerting on metric thresholds, we limit ourselves to the granularity of the metrics. Consider a scenario where interface statistics are gathered every five minutes. That limits the ability to capture anomalous traffic patterns to a five minute interval, and at the fast pace of modern datacenters, that level of granularity isn’t acceptable. Limiting the alerting ability based on the thresholds.
Secondly, there are many times when alerts from certain metrics don’t create any actionable activities. For example, an alert on CPU utilization may not directly have an impact on traffic. Since switch CPUs should Continue reading
In the wake of the Technology and Manufacturing Day event that Intel hosted last month, we were pondering this week about what effect the tick-tock-clock method of advancing chip designs and manufacturing processes might have on the Xeon server chip line from Intel, and we suggested that it might close the gaps between the Core client chips and the Xeons. It turns out that Intel is not only going to close the gaps, but reverse them and put the Xeons on the leading edge.
To be precise, Brian Krzanich, Intel’s chief financial officer, and Robert Swan, the company’s chief financial …
