These patterns provide insight into how a system is actually performing and what kinds of latency end-user applications experience. Many characteristics seen in these patterns are still not understood, but so far their analysis is revealing systemic behaviors that were previously unknown.<\/jats:p>","DOI":"10.1145\/1794514.1809426","type":"journal-article","created":{"date-parts":[[2020,9,3]],"date-time":"2020-09-03T03:40:15Z","timestamp":1599104415000},"page":"30-42","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Visualizing System Latency"],"prefix":"10.1145","volume":"8","author":[{"given":"Brendan","family":"Gregg","sequence":"first","affiliation":[{"name":"Oracle"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2010,5]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1117389.1117401"},{"key":"e_1_2_1_2_1","unstructured":"Gregg B. 2009 (Feb. 6).
