Cutting through alert noise with high quality alerts

As applications, services and infrastructure accumulate over time (organically or through mergers and acquisitions), ITOps organizations add monitoring tools that generate more alerts. As alert volume increases over time, the quality and usefulness of alerts tend to decline, making it hard to discern which alerts are important and need attention. In many cases, however, no structured practice exists for regularly assessing alerts to determine whether they need to be modified or retired. Left alone over time, the resulting environment of IT noise can dramatically overwhelm even the most well-designed incident and alert management workflows and intentions.

Consider the hypothetical case where an organization receives 500 monitoring alerts in its first year. As the scope of monitoring grows, the number of new alerts generated, in addition to the existing alerts, increases by 15%. After 10 years, assuming none of the alert sources were taken out of service, there will be 12,175 total configured alerts in the environment.
