If the keyword Aggregate is used then it is called a processed reading and if the
keyword is not used, it is just called a raw reading.
Keyword Restrictions
When you use the command GET_HISTORY there are some keyword that are
mandatory but there are also “other keywords” which are optional. These keywords
have restrictions when it comes to mutual dependencies.
• When you use the Aggregate option then you also must give either
RESAMPLE or COUNT.
• If you give both RESAMPLE and COUNT, then the resample value calculated
from COUNT overrides the value in RESAMPLE.
• You are not allowed to use MAXCOUNT together with any of the other
optional keywords. You should only use this to maximize the number of rows
read in a raw reading.
RESAMPLE The time between resample on processed reading, in seconds.
Ex, RESAMPLE=10000
COUNT Number of returned values expected from the command
(overrides and/or changes the resample value)
Ex, COUNT=2 (returns two values)
MAXCOUNT Maximal number of values to read on a raw reading.
Ex, MAXCOUNT=1000000
STORAGEINF
O
Gives information on the logs that exists in the system or
information about the short references saved in the system. This
depending on how you use it.
Ex, STORAGEINFO, GET_DATA(STORAGEINFO),
GET_HISTORY(STORAGEINFO)
(1) The Object GUID, Globally Unique Identifiers, identifies each object so it is unique.
