This document present the performance of ryjson1 application,which checks Rye specifications over multiline JSON logfiles and provide a command line interface to Reelay monitors.
We use timescales benchmark generator to measure the performance of ryjson1. The benchmark covers a number of common classes of specifications with timing constraints. More information regarding the benchmark generator and motivations can be found in the paper of Timescales: A Benchmark Generator for MTL Monitoring Tools.
The benchmark can be replicated by typing commands at the Reelay project directory. First generate some data using timescales by typing
make timescales
This command will clone timescales generator and generates discrete and dense time behaviors for benchmarking. The total size of generated benchmarks is about 2.2GB. There are two variant for dense time behaviors with two different degrees of condensation.
make test_performance_discrete
make test_performance_dense10
make test_performance_dense100
To execute these commands, you need multitime utility for benchmarking with these commands, which can be installed via apt or from source.
Below we present performance of ryjson1 aapplication on a laptop computer (Intel Core i5-7200U CPU @2.50 Ghz, 8GB RAM) on Ubuntu 20.04 and using the version 2008 of Reelay. And we report minimum user time of 10 executions.
Results over processing discrete time behaviors with a length of 1M.

Condensation allows to represent periods of the same JSON object with a single timestamped object. Dense10 behaviors limits this feature maximum 10 successive time points. Consequently the same temporal behavior is expressed a shorter logfile (up to 10x). Dense time monitors may work over such condensed (dense) logfiles.
