SNMP Polling


Overview:

These examples have "two towers", which mean, there are two power strips, one with a snmp pollable cpu "A", and another one "B" that is polled by "A" via a interconnect. 

Each Tower has three circuits A-C, so when viewing the feeds, you will see AA (tower A, ckt A).... AC (tower A, ckt C)... BA...BB....BC...

You can get data about the power strips via ssh, https, and snmp polling.  For simplicity sake, we will be showing the data via the web, and then showing how to get it from SNMP polling. 

Note that the ServerTech MIB info can be downloaded from here:

Input Power:

Web:

From the Power Monitoring, Input Feeds section, we see the following data:
 Note  Name  Example Data
  Description
 (1)  Input Feed ID
  AA  First letter lists the tower (the power strip) <A-B>, and the second letter lists each towers circuit <A-C>.
 (2)  Input Feed Name
 TowerA_InfeedA  User definable name for each "feed" (tower/ckt combo).  Currently set to defaults, but can be modified as needed.
 (3)
 Input Status  
 On
 If the ckt to a power strip is switched on or off. 
 (4)
 Input Load
  4.77 A
  The total amp draw for the circuit.  (remember that there are 3 ckts per power strip.)
 (5)  Input Voltage   
 208.0 V
  The input voltage on the power strip
 (6)  Input Power
  992 W
  The watts in use by the ckt.

Output Power

WEB:

From the Outlet Control and Invifidual sections, you can view all the outlets, and power cycle them as needed.

Because these units are "CW" and not "CWG" we can only control the power for the output legs, we can not monitor them.



 Note  Name    Example Data    
Description
 (1)  Outlet ID
  AA1  Shows the TowerCktOutlet code for each outlet
 (2)  Outlet Name
  Server1-ckt1  The custom name for the outlet.  Lets you remember what's plugged into it.
 (3)  Outlet Status
  On  Says if the outlet is on or off or in a reboot state
 (4)  Control Action
  Reboot     You can turn a power outlet off, or "reboot" which shuts the power off momentary, and then brings it back on.
