OpenTelemetry: The key to modern enterprise observability | Elastic

2 months ago | elastic.co | David Hope

Transform your organization's observability strategy with open standards and simplified data collectionModern organizations face an unprecedented observability challenge. As systems grow more complex and distributed, traditional monitoring approaches are struggling to keep pace. With data volumes doubling every two years and systems spanning multiple clouds and technologies, organizations need a new approach to maintain visibility into their operations.

Level up your observability practice: Common challenges, practical steps, and the importance of leadership

Nov 20, 2024 | elastic.co | David Hope

Lessons from the front lines: Challenges in your observability maturity journey In our previous blog, we explored the observability maturity spectrum — revealing that while only 7% of organizations consider themselves experts, the majority (43%) are actively working to improve their practices. We saw how mature organizations achieve better outcomes, from faster root cause analysis to reduced user-reported incidents. Now, let's tackle the practical side of advancing your observability maturity.
Level up your observability practice and see measurable benefits

Lessons from the front lines: Moving to observability maturityWhat separates the observability experts from the novices? It's a question that's been on my mind lately, especially after diving into our recent 2024 State of Observability Survey of over 500 practitioners. In my past roles as a DevOps engineer and a site reliability engineer (SRE), I've seen firsthand how a mature observability practice can be the difference between sleepless nights and smooth sailing.
Hybrid IAM: Securing Asia’s distributed IT future

Oct 26, 2023 | frontier-enterprise.com | David Hope

Recent trends in the digital economy have accelerated the transition to a distributed IT infrastructure. In response to these changes and the increasing demands of an interconnected world, there has been a shift in how IT systems are managed, moving from a centralised hub to a decentralised model. One of the major drivers behind this shift is an ongoing global transition towards hybrid work that has been accelerated by the pandemic.

Highlights•Mpox infection by three routes induces robust natural immunity•Natural immunity protects against mpox re-challenge•Adaptive immune responses appear critical for protectionSummaryThe mpox outbreak of 2022–2023 involved rapid global spread in men who have sex with men. We infected 18 rhesus macaques with mpox by the intravenous, intradermal, and intrarectal routes and observed robust antibody and T cell responses following all three routes of infection.
Elasticsearch：使用 ESRE 和生成式 AI 了解 TLS 日志错误

Sep 5, 2023 | blog.csdn.net | David Hope

作者：DAVID HOPE 本博客介绍了 Elasticsearch 相关性引擎 (ESRE) 及其 Elastic Learned Sparse Encoder 功能的新颖应用，特别是在日志分析中。最近发布的 Elasticsearch Relevance Engine™ (ESRE™) 包含一系列重要功能，可增强搜索能力，并可使用与询问生成式 AI 问题相同的自然语言来查询 Elasticsearch®。这让我想知道我们如何将其用于日志。开始使用 Elastic Learned Sparse Encoder 模型相当容易，这是一种支持语义搜索的重要 ESRE 功能 - 我们将在本博客中介绍如何使用它进行日志记录。此功能与 Elasticsearch® 当前的功能有很大不同，因为它理解单词的含义并广泛搜索具有相似含义或与我搜索的单词同义的单词。 Elastic Learned Sparse Encoder 也是一种高效的搜索排名解决方案，在域外空间（即，当模型未严格根据用户数据进行训练时），可产生比传统 BM25 和基于向量的 KNN 搜索更好的结果。...
Manual instrumentation of Java applications with OpenTelemetry
