Hi,
I am new to PRTG, and while my experience has been great so far, I am stuck with some manual / scripted sensor manipulations.
Specifically, I am trying to chart EMC Data Domain physical capacity measurements, values which are not exposed by the EMC Data Domain MIB, but can be obtained at a command line as follows:
SERVICES\jonathanb@hostname# compression physical-capacity-measurement sample show history
MTree: /data/col1/MTREE_ONE
Measurement Time Logical Used Physical Used Global-Comp Local-Comp Total-Comp
(Pre-Comp) (Post-Comp) Factor Factor Factor
(GiB) (GiB) (Reduction %)

Total number of measurements retrieved = 10.
The goal is that each MTREE (think directory / accounting unit), I want to plot Logical Used and Physical Used over Time; where time would be sampling once per week. This information is currently available in a different system, but I want to record and expose it through a PRTG MAP:
The challenge with the SSH Script sensor is that the DDOS is locked down so that you can't create or store a script on it.
- Any suggestions how I could access the data from PRTG?
- Any suggestions how I could parse the entries in PRTG into channels to allow the type of chart I need?

Hi Felix,
In this case, DDOS = Data Domain Operating System, the highly customised OS running on EMC Data Domain systems.
It affects the script because you can't write to the file system, you can't put a script on the Data Domain.
I am thinking I may need to store something like a Powershell script locally on my PRTG host, and use that to establish an SSH session to the Data Domain, and parse the returned values into channels...but I have no idea how to do that.

Hi there,
Thanks for clearing that up with the "DDOS". :)
You can also try to build a PowerShell-script (as you already suggested) by using the "EXE/Script Sensors":
https://www.paessler.com/manuals/prtg/exe_script_sensor
https://www.paessler.com/manuals/prtg/exe_script_advanced_sensor
The correct syntax of these sensors is described within the PRTG Webinterface under "Setup > PRTG API".
Best regards.

Hello JBourke,
I understand what you try to achieve, but I only know DDoS as a Distributed-Denial-of-Service, how exactly does this affect the creation of the script?
There are two ways to create you own sensor:
The required syntax to create multiple channels is described on the
Setup | PRTG API | Custom Sensor page.
Best regards, Felix
