Sometimes a metric needs to fall between a range to be considered OK, and outside the range (i.e. above and below) for a warning, and outside that range (i.e. above and below) for a critical. So for example monitoring the input voltage into a APC UPS to ensure it is within a certain range. So lets say OK is between 220 and 240, WARNING would be between 210 and 219; and 241 to 250. With CRITICAL being less than 209 or greater than 251. So something like: < 220 and 240 < means OK > 219 and < 241 means WARNING > 209 and < 251 means CRITICAL. To configure the Nagios check use the following, this example pulls out the input voltage from the UPS: $USER1$/check_snmp -H 172.17.1.15 -o .1.3.6.1.4.1.318.1.1.1.3.2.1.0 -C community -w 219:241 -c 209:251 So some examples if the input voltage is: 230v = OK (within the range of 220 to 240) 218v = WARNING (below the range of 219 for warning) 255v = CRITICAL (above the range of 251 for warning) |
