[storage::hp::3par::ssh::plugin] Request a new mode "psu"

[Aleksey-Maksimov]

Hello

Please make a new mode psu in storage::hp::3par::ssh::plugin to check the status of 3PAR storage power supplies and batteries.

The current implementation of monitoring in the psu.pm code does not have checks for power supply fans. 3PAR power supplies (in main cage) have special batteries, the state of charge of which also needs to be monitored. The current implementation of monitoring in the battery.pm code does not allow us to get an extended status of the battery. The information from the shownode -ps -verbose command will allow us to get extended battery status and additional data for perfdata.

The data we need to check in each section "---------------Node*"

1. The parameter "State" must be "OK" for each psu
2. The parameter "Fan State" must be "OK" for each psu
3. The parameter "AC State" must be "OK" for each psu
4. The parameter "DC State" must be "OK" for each psu
5. The parameter "Battery State" must be "OK" for each psu
6. Parameters "Battery Detail State", "Battery Charge State" must be in plugin output with --verbose option

Here we suppose to see perfdata for "Battery Charge Level(%)" and "Max Battery Life(mins)" with warn/crit thresholds

Examples:

3PAR02 cli% shownode -ps
