[Trend]MaxRequestLength

  • Last UpdatedJul 19, 2023

The maximum size of a trend request measured in the number of samples that a trend server will accept from clients. This parameter protects the trend server from being overloaded by requests that are too large. Decreasing this parameter will cause smaller trend requests to be rejected, increasing its value will let the trend server process large requests which could reduce the responsiveness of the trend server to smaller requests.

Note: Trend redundancy backfilling requests from the peer trend server are never rejected, regardless of what setting is applied to this parameter. In order to control the size of trend redundancy requests, use the parameter [Trend]MaxRdnSamples.

Allowable Values:

1 to 100000000

Default Value:

4000
