PT Unknown AU Waller, J TI Benchmarking the Performance of Application Monitoring Systems SE Bericht des Instituts für Informatik PY 1992 VL 1312 PU Institut für Informatik WP https://macau.uni-kiel.de/receive/macau_mods_00001785 LA en SN 2192-6247 AB Application-level monitoring of continuously operating software systems provides insights into their dynamic behavior helping to maintain their performance and availability at runtime. Such monitoring may cause a significant runtime overhead to the monitored system depending on the number and location of used instrumentation probes. In order to improve a system's instrumentation to reduce the caused monitoring overhead, it is necessary to know the performance impact of each probe. In this paper, we present our MooBench approach to split the possible causes of monitoring overhead into three portions, and to quantify these portions of monitoring overhead with the help of benchmarks under controlled and repeatable conditions. To the best of our knowledge, most publications on monitoring frameworks provide none or only weak performance evaluations, making comparisons cumbersome. Our benchmark approach provides a basis for such comparisons. PI Kiel ER
