the loss of a backup ISP connection. Notify staff who can
fix the problem.
2 Critical
A condition requiring immediate correction or indicating
a failure in a primary system, for example, a loss of a
primary ISP connection. Fix CRITICAL issues before ALERT-
level problems.
3 Error
Non-urgent failures. Notify developers or administrators
as errors must be resolved within a given time.

an error will occur if required action is not taken. An
example is a file system that is 85% full. Each item must
be resolved within a given time.

These items might be summarized in an email to
developers or administrators to spot potential problems.
No immediate action is required.
6 Informational

for network maintenance functions like reporting and
throughput measurement. No action is required.
