Package it.jnrpe.utils.thresholds Description

This package contains all the classes used to parse and manage new thresholds format according to the Nagios specification RFC (http://nagiosplugins.org/rfc/new_threshold_syntax). As per the RFC:

Threshold arguments are specified like: --threshold={threshold definition} The threshold definition is a subgetopt format of the form: metric={metric},ok={range},warn={range},crit={range},unit={unit}, prefix={SI prefix} Where:

• ok, warn, crit are called "levels"
• any of ok, warn, crit, unit or prefix are optional
• if ok, warning and critical are not specified, then no alert is raised, but the performance data will be returned
• the unit can be specified with plugins that do not know about the type of value returned (SNMP, Windows performance counters, etc.)
• the prefix is used to multiply the input range and possibly for display data. The prefixes allowed are defined by NIST:
  • http://physics.nist.gov/cuu/Units/prefixes.html
  • http://physics.nist.gov/cuu/Units/binary.html
• ok, warning or critical can be repeated to define an additional range. This allows non-continuous ranges to be defined
• warning can be abbreviated to warn or w
• critical can be abbreviated to crit or c
