|Applies To||Envision (All Currently Supported Versions)|
|Issue||Queries & Reports Showing No Data|
I am collecting data from my device, but my reports are showing no information. Where should I begin troubleshooting?
When troubleshooting why a report is returning no data, you should begin at the source and work your way forward.
Assuming that you are collecting data for your device (raw data shows up in the Event Viewer), the first step would be to verify that Envision is parsing the messages correctly.
In the Event Viewer, please do the following:
1. Click Graph View >> Events by Event Type
What this should do is give you a graph of all of the events you received from this specific device. Make a note of these message IDs.
The next step is to look up those messages to see to what table those messages are assigned and to insure that those messages are enabled.
On the Overview tab:
1. Go to System Configuration >> Messages >> Manage Messages To Parse
Assuming that all of this is correct, use the Query tool (which uses the same engine as reporting) and confirm that you are seeing data returned.
You should also look under Manage Monitored Devices to insure that your device is marked to Analyze.
Finally, if all of these are correct, look at any SQL you may have used to see if it is limiting the data returned.
