DC_HistoricalOutput Table Blank

[Rob Buxton]

Under IM 7 I'd written some reports that pulled Historical data from this table.

The table is still there under SIM, but is empty.
Is the data now stored elsewhere or is there something amiss?
SIM has been running for a few months so I'd expect just a bit of Historical info.

TIA
Rob.

Did you change the data collection task, un-ticking 'Overwrite existing data set' and ticking 'Append new data set (for historical trend analysis)' ?

David,
I think I'm still running the defaults, Overwrite Existing Data is still checked.

Do I need to set up an additional Hardware Data Collection Task to record the Historical info?

[David Claypool]

You should be able to just change it. I think the description of 'Single...' is misleading when it says it is more complete. [Note to developers...]

David,

Thanks, I set up and ran a separate task which has now populated the DC_Historical Table.
Does this mean then that another table will not be populated? e.g. DC_Output?

I'll change the default task and remove the new one for now.

Rob.

David,
In IM 7, I'd set up a Daily Task that updated the Historical Info. (it used the default Data Collection Query) so that I could do Trend Anaylysis.
I don't think this updated the Reports Tables, but could be wrong.
In SIM, are these two functions combined, as there doesn't seem to be too many options on the Bi-Weekly Task that currently does the Data Collection. And, I thought also updated the Reports Tables.

Of course, I could be misunderstanding the older workings of CIM 7 and SIM here.

I'll play a little with it tomorrow to make sure, but I'm pretty sure that with the historical collection it is a superset of single instance data...
