For your next setup check out the cyberpower pdu's. The SNMP data is more detailed, and doesn't require an applet (and whacky browser settings) to control it. It has a clean web interface you can get to easily.

It outputs per-bank load so you can balance easier, vs the single reading from the tripplite. It some other data too that's neat to see (power consumed since startup, resettable), like this:

CPS-MIB::ePDULoadStatusLoad.1 = Gauge32: 158 CPS-MIB::ePDULoadStatusLoad.2 = Gauge32: 81 CPS-MIB::ePDULoadStatusLoad.3 = Gauge32: 77 CPS-MIB::ePDULoadStatusVoltage.1 = INTEGER: 2378 CPS-MIB::ePDULoadStatusVoltage.2 = INTEGER: 2378 CPS-MIB::ePDULoadStatusVoltage.3 = INTEGER: 2378 CPS-MIB::ePDULoadStatusActivePower.1 = INTEGER: 3630 CPS-MIB::ePDULoadStatusActivePower.2 = INTEGER: 1863 CPS-MIB::ePDULoadStatusActivePower.3 = INTEGER: 1767 CPS-MIB::ePDULoadStatusApparentPower.1 = INTEGER: 3755 CPS-MIB::ePDULoadStatusPowerFactor.1 = INTEGER: 96 CPS-MIB::ePDULoadStatusEnergy.1 = INTEGER: 240261 CPS-MIB::ePDULoadStatusEnergyStartTime.1 = STRING: "2017/06/13 07:46:47" CPS-MIB::ePDUStatusInputVoltage.0 = INTEGER: 2378 CPS-MIB::ePDUStatusInputFrequency.0 = INTEGER: 600

I have the same tripplite you posted, and also have one of these: https://www.newegg.com/Product/Product.aspx?Item=N82E16812220107&cm_re=CyberPower_PDU30MVHVT24FNET-_-12-220-107-_-Product

The only way I too see if a bank is overloaded on the tripplite is to wait until it pops the breaker for the bank (It happened to me... dual mining testing)

For my next build I'll use one of these instead, it has per-port on/off plus the good snmp output:https://www.newegg.com/Product/Product.aspx?Item=9SIA91J4344133&cm_re=CyberPower_PDU30SWHVT16FNET-_-9SIA91J4344133-_-Product

I'm tempted to add the environmental sensor to it too, there's a block of snmp data for that also.

I'm sure there's other PDU's way better than the cyberpower ones, but for the price and features, I like them.

Awesome mining cave btw
