Meta tags
Meta tags are used to perform various aggregations and calculations in order to retrieve results for statistical analysis or user presentation. Alarm analysis meta tags allow A&E data KPIs to be queried and visualised just like any process data source. View a full list of KPIs here.
KPIs
The following meta tags are available for asset, tag and alarm identifier data aggregations (string before the meta tag will be used to match A&E data which will be used for analysis). For example:
- `Oil Co/Osprey/KPI No ALM` - This will get the number of alarms for *Oil Co/Osprey* asset.
- `Oil Co/Osprey/LIC040/KPI No ALM` - This will get the number of alarms for *LIC040* tag.
- `Oil Co/Osprey/LIC040/HIHI/KPI No ALM` - This will get the number of alarms for *LIC040 HIHI* tag.
Key:
- † Indicates that KPI supports excluding empty aggregation buckets, for example if property `ExludeEmptyBuckets` set to true it won't take empty days when calculating averages. See examples for more info.
