Monitoring tools for DevOps and microservices: A systematic grey literature review

Microservice-based systems are usually developed according to agile practices like DevOps, which enables rapid and frequent releases to promptly react and adapt to changes. Monitoring is a key enabler for these systems, as they allow to continuously get feedback from the field and support timely and tailored decisions for a quality-driven evolution. In the realm of monitoring tools available for microservices in the DevOps-driven development practice, each with different features, assumptions, and performance, selecting a suitable tool is an as much difficult as impactful task. This article presents the results of a systematic study of the grey literature we performed to identify, classify and analyze the available monitoring tools for DevOps and microservices. We selected and examined a list of 71 monitoring tools, drawing a map of their characteristics, limitations, assumptions, and open challenges, meant to be useful to both researchers and practitioners working in this area. Results are publicly available and replicable

Efficacy of extracorporeal focused shock waves therapy in patients with enthesopatic chronic pain

Introduction. Extracorporeal Shock Waves are worldwide used for the treatment of musculoskeletal disorders, even though there is still disagreement regarding its appropriate use and efficacy. This pilot study is aimed to evaluate the efficacy of Focused Shock Waves Therapy in reducing enthesopatic chronic pain. Materials and methods. We recruited 35 patients suffering from chronic pain due to enthesopathy (at lower and upper limbs). All the patients included were previously treated with drug therapy without achieving significant results in terms of improvement in pain. We excluded all patients with chronic pain due to other causes (neuropathic, dismetabolic, rheumatic, psychogenic). We evaluated all patients using the “Brief Pain Inventory” (BPI) and Visual Analogic Scale (VAS) before (T0) and after 4 treatments (T1). The treatment was carried out with shock waves generated for a focal, electro-hydraulic principle. The energy was applied in 4 sessions over a range between 0.13 and 0.88 mJ /mm ², without application of local anesthetics. Results. Our study population was composed by 35 patients (16 M and 19 F, mean age 52.3). The mean of the BPI pain severity index and the BPI pain interference index at T0 was 7.85 and 7.17 respectively, while at T1 was 1.43 and 0.82; if we consider the VAS at T0 the mean score was 7.94 and at T1 it was 1.60. If we consider only male subjects the mean of the BPI pain severity index and the BPI pain interference index at T0 was 7.31 and 6.96 respectively, while at T1 was 1.32 and 0.88; the mean VAS score at T0 was 7.31 and at T1 it was 1.44. In the female group the mean of the BPI pain severity index and the BPI pain interference index at T0 was 8.31 and 7.35 respectively, while at T1 was 1.53 and 0.77; the mean VAS score at T0 was 8.47 and at T1 it was 1.74. Conclusions. In our study we found a significant reduction of chronic pain and a significant improvement in the quality of life both in female and in male patients affected by enthesopathy.
