Drowning in data? You probably just started monitoring your application. Modern applications overwhelm users with an avalanche of metrics representing their functions and behaviors. Sysadmins are flooded with alerts about their CPU or Network I/O crossing preset thresholds. Developers might be watching a stream of application-level metrics like the gossip protocol activity on a Cassandra ring. Overwhelmed, they’ll either turn off their monitoring tool, spend weeks tuning it, or give up and accept the unstructured noise.
Rackspace Cloud Monitoring currently samples about 40,000 metrics per second across our cloud-hosted instance flavors. This data accumulates minute by minute and more checks are enabled every day. There's a lot of data here—an automated layer of intelligence over our cloud environments could really help.
