Today we've released in our donwload site the Nagios plugin check_cpqups_mode. This plugin allows knowing the working mode and status of HP (Hewlett Packard) UPS devices supporting SNMP and CQPUPS-MIB.

Plugin manages the device reported information for stating the working mode as one of the following:

• Online: Working mode in which UPS is getting power supply in its input(s) and protecting the attached devices with the power supplied by its batteries.
• Offline: Working mode in which device is not getting power supply in its input(s) but devices  are protected by batteries. Plugin interprets this state as three possible sub-states: Offline, offline with low battery power and offline with depleted batteries.
• Bypass: Working mode in which UPS is not protecting the attached devices, only transfering power from its inputs to its outputs.

Additionally to the working mode, plugin reports information about battery charge level and autonomy time, in minutes, based on battery level and UPS output consumption. User can set warning and critical thresholds based on both battery levels and autonomy time.
