Changelog

  • fixed host check return codes (livestatus, status_dat)

the following variables allow to tweak this behaviour:

  map_host_down_state_to and map_host_unreachable_state_to
* added history with new computed macros (AVERAGE, WEIGHTED_AVERAGE,
  MIN, MAX, DELTA, AVERAGE_DELTA, WEIGHTED_AVERAGE_DELTA)
* changed Getopt::Long handling to allow old Perl versions
* new switch html_ascii_notification allows ASCII part in HTML output
* reorganized ascii verbose mode, prints selectable fields
* info [ tag::pre_nok ] - info text for non OK states
* info [ tag::pre_<status> ] adds info texts depending on status
* info [ tag::{pre,post} ] provides info texts for child checks
