What is the correct way to call EwsClient.ExtractHistroyItemIds on an AS?

[sesa180961_brid]

I have a few Interval Trend Logs on an AS in a specific folder. This AS is attached to an ES.

"03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs"

In a SmartConnector, I would like to get Interval Trend Logs using EwsClient.ExtractHistoryItemIds or EwsClient.ExtractHistoryItems.

When I call using these parameters, it does not work.

itemIds = c.ExtractHistoryItemIds(false, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);  items = c.ExtractHistoryItems(false, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);

But when I call the same method using the true parameter, it returns but takes a while to return.

itemIds = c.ExtractHistoryItemIds(true, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);  items = c.ExtractHistoryItems(true, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);

The EwsClient version is 2.2.108.0

I assumed that if the path to the logs is known, passing false should work. Is there some setting on the AS that should be set or some other parameter I am missing?

Thanks in advance!!

Hi Maneesh,

I think this isn't working because when it is set to False it is expecting a list of Container Items Ids, but from what I can see, you havent passed in any ContainerItem Ids, but actually HistoryItem Ids.

itemIds = c.ExtractHistoryItemIds(false, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);  
items = c.ExtractHistoryItems(false, new List<string> { "03/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);

should probably be changed to:

itemIds = c.ExtractHistoryItemIds(false, new List<string> { "00/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);  
items = c.ExtractHistoryItems(false, new List<string> { "00/Server 1/Servers/DFW18_S220_DCIM04/TrendLogs" }, 5);

Notice 03 has been changed to 00 in the prefix of your Container Item IDs.

Below are what the prefixes in the SBO EWS Ids mean:

00 - Container Item

01 - Value Item

11 - Value item, that is a property of another Value Item

02 - Alarm Item

03 - History Item

I see. That explains it. Thanks!
