Free Disk Space on PROPLUS

Ladies and Gents.

We are using DV v.14.3.1 and I am about to create controle modules compiling the most relevant diagnostic parameters for every hardware part of the DeltaV-system and provide them via OPC-interface to our OSI SOFT PI System.

From the workstation/server point of view the FREMEM parameter is already included to inform about the free disk space at volume D:\

Up to now I haven´t found a possibility to access this value also for the C:-drive. Due to disk usage of alarms&events, continious historian, etc. maintening the free space on C: would be very interesting for me as well.

Maybe there are any "secret" parameter or smart work arounds.

Thanks in advance

  The FREMEM diagnostic parameter is the amount of memory available for user control strategy configuration in either the controller (physical controller) or virtual controller (workstation/server). This has no relationship with the available space on any disk drives for the nodes that are not physical controllers.
  
  There are some parameters that give you the amount of space before your event chronicle fills up (PROPLUS/ECHRON/HDSXSMB) or you batch historian is full (BHISTORIAN/BHIST/SPACE 0-100% used).
  
  For ECHRON/HDSXSMB this value kind of shows the free space on your D: if that is where your DVDATA folder is. The definition from Books On-Line:
  
  >>>
  Shows the disk space, in MB, available on the primary storage drive if the Event History databases (active and current) reached their configured size target.
  
  A negative value indicates that there is currently insufficient storage to accommodate the maximum configured size target.
  <<<
  
  I did find one parameter that is the actual disk space on your DVDATA drive in MB (divide by 1024 to get GB) that is NODENAME/FREDISK.CV
  
  For monitoring other drives besides the DVDATA drive will need some other method of monitoring. The System Health Monitor product can monitor a large number of items on your system and provide alerts via e-mail so it will need some sort of access to your business network through the appropriately configured firewalls. It also links to Emerson GSC and will log service calls automatically for significant problems.

  In reply to Scott Thompson:

  Thank you very much Scott. As mentioned above monitoring CTRLs and D:-drives wasn´t that tricky and is done already. I´ll check the system health monitor datasheets for further information.
