Limitations¶

Queries, exports, and page configurations in Unified Monitoring are subject to limits. Actual thresholds can vary by page version and runtime environment; messages displayed on the page take precedence over the general guidance in this topic.

Query Scope¶

Query volume is typically affected by all of the following:

Number of selected assets.
Number of selected data items.
Time range.
Time granularity.
Whether subtotals, aggregations, or detailed data are included.

A finer time granularity produces more data points and usually shortens the available query range.

If a limit is reached, reduce the number of assets or data items, shorten the time range, use a coarser time granularity, or run the query in batches.
