getRecentPerformanceSamples RPC Method

Returns a list of recent performance samples, in reverse slot order. Performance samples are taken every 60 seconds and include the number of transactions and slots that occur in a given time window.

Parameters

limit usize optional number of samples to return (maximum 720)

Result

An array of RpcPerfSample<object> with the following fields:

  • slot: <u64> - Slot in which sample was taken at
  • numTransactions: <u64> - Number of transactions processed during the sample period
  • numSlots: <u64> - Number of slots completed during the sample period
  • samplePeriodSecs: <u16> - Number of seconds in a sample window
  • numNonVoteTransaction: <u64> - Number of non-vote transactions processed during the sample period.
info

numNonVoteTransaction is present starting with v1.15. To get a number of voting transactions compute: numTransactions - numNonVoteTransaction
