XPDDS18: Real Time in XEN on ARM - Andrii Anisov, EPAM Systems Inc.The Linux Foundation
Currently, several initiatives promote XEN hypervisor into the automotive area as a base of complex virtualized systems. To support those initiatives and plunge into the automotive world XEN should fit at least two requirements: it should be appropriately certified and to be able to host a security domain. Leaving behind certification topic, here we focus on security domain hosting capability of XEN. Particularly on keeping RT guarantees for the specific domain.
This talk is a presentation of the investigation on a XEN hypervisor applicability to building a multi-OS system with real-time guarantees being kept for one of the hosted OSes.
During this presentation following topics would be outlined:
- experimental setup
- experimental use-cases and their motivation
- received results and discovered issues
- solutions and mitigation measures for discovered issues
OSDC 2017 - Werner Fischer - Linux performance profiling and monitoringNETWAYS
Nowadays system administrators have great choices when it comes down to Linux performance profiling and monitoring. The challenge is to pick the appropriate tools and interpret their results correctly.
This talk is a chance to take a tour through various performance profiling and benchmarking tools, focusing on their benefit for every sysadmin.
More than 25 different tools are presented. Ranging from well known tools like strace, iostat, tcpdump or vmstat to new features like Linux tracepoints or perf_events. You will also learn which tools can be monitored by Icinga and which monitoring plugins are already available for that.
At the end the goal is to gather reference points to look at, whenever you are faced with performance problems.
Take the chance to close your knowledge gaps and learn how to get the most out of your system.
Analyzing OS X Systems Performance with the USE MethodBrendan Gregg
Talk for MacIT 2014. This talk is about systems performance on OS X, and introduces the USE Method to check for common performance bottlenecks and errors. This methodology can be used by beginners and experts alike, and begins by constructing a checklist of the questions we’d like to ask of the system, before reaching for tools to answer them. The focus is resources: CPUs, GPUs, memory capacity, network interfaces, storage devices, controllers, interconnects, as well as some software resources such as mutex locks. These areas are investigated by a wide variety of tools, including vm_stat, iostat, netstat, top, latency, the DTrace scripts in /usr/bin (which were written by Brendan), custom DTrace scripts, Instruments, and more. This is a tour of the tools needed to solve our performance needs, rather than understanding tools just because they exist. This talk will make you aware of many areas of OS X that you can investigate, which will be especially useful for the time when you need to get to the bottom of a performance issue.

HKG18-TR14 - Postmortem Debugging with CoresightLinaro
Session ID: HKG18-TR14
Session Name: HKG18-TR14 - Postmortem Debugging with Coresight
Speaker: Leo Yan
Track: Training
★ Session Summary ★
For most cases we can easily debug with kernel's oops dumping info, but sometimes we need to know more information for program execution flow before the issue happens. So we can rely on two tracing methods to reproduce the program execution flow, one method is using software tracing which is kernel's pstore method; another method is to rely on Coresight hardware tracing, this method also can avoid extra workload introduced by tracing itself. Coresight has provided two mechanisms for Postmortem debugging, one method is Coresight CPU debug module so we can extract CPU program counter info, this is quite straightforward to debug CPU lockup issue; Another is Coresight panic kdump, we connect kernel kdump mechanism to extract Coresight tracing data so we can reproduce the last execution flow before panic (even hang issue with some tweaking in kernel). This session wants to go through these topics and demonstrate the debugging tools on 96boards Hikey in 25 minutes session.

This presentation shows examples of how to use FPP and different configuration options.
Talk for YOW! by Brendan Gregg. "Systems performance studies the performance of computing systems, including all physical components and the full software stack to help you find performance wins for your application and kernel. However, most of us are not performance or kernel engineers, and have limited time to study this topic. This talk summarizes the topic for everyone, touring six important areas: observability tools, methodologies, benchmarking, profiling, tracing, and tuning. Included are recipes for Linux performance analysis and tuning (using vmstat, mpstat, iostat, etc), overviews of complex areas including profiling (perf_events) and tracing (ftrace, bcc/BPF, and bpftrace/BPF), advice about what is and isn't important to learn, and case studies to see how it is applied. This talk is aimed at everyone: developers, operations, sysadmins, etc, and in any environment running Linux, bare metal or the cloud.

It discusses analyzing performance across abstraction layers, introducing Hadoop and its architecture, and demonstrating tools like zonestat, mpstat, fsstat, and prstat to monitor CPU, memory, disk I/O, and other metrics at both the system and per-zone level.
This document provides an overview of the MySQL sys schema. It discusses how sys schema provides views and functions on top of the Performance Schema to implement common DBA and developer use cases. It covers installing sys schema, the various formatting and helper functions it includes, and the summary views it provides for analyzing user activity, I/O, schema objects and more.
This document provides an overview and summary of MySQL Cluster. It discusses how MySQL Cluster provides high availability, scalability and performance through features like auto-sharding, multi-master replication, ACID compliance, and built-in high availability. It also provides examples showing how MySQL Cluster can scale to handle over 1 billion updates per minute and discusses how operations like restarts have been improved in MySQL Cluster 7.4.1.
The document discusses Oracle's Automatic Workload Repository (AWR) and how it can be used to analyze database performance issues. It provides an overview of AWR basics and functionality, walks through analyzing an AWR report including a real-world case study of identifying a performance regression, and discusses AWR administration and diagnostics.
The document discusses memory usage in Linux systems. It begins by describing the boot process and how the kernel loads into memory. It then explains that Linux uses virtual memory, where each process has its own virtual address space. Physical memory is limited by factors like CPU architecture and motherboard configuration. When an executable runs, not all of its code is loaded; dynamic libraries it depends on are mapped into its address space as well, significantly increasing its memory usage compared to the executable size alone.

The document discusses SQL tuning methodology. The three pillars of SQL tuning are: 1) diagnostics collection to identify problematic SQL, 2) root cause analysis to determine why SQL is performing poorly, and 3) remediation steps to address issues. It covers tools for diagnostics collection like SQL trace, AWR, and explains execution plans and the cost-based optimizer. The document provides a methodology for SQL tuning including identifying SQL, collecting data, analyzing root causes, and testing and implementing solutions.
This document discusses Oracle wait events. It explains that wait events track where Oracle is spending its time, including different types of waits like CPU time, I/O events, enqueue events and latch events. It provides examples of specific wait events like db file sequential read, direct path write, log file sync and buffer busy waits. It also gives recommendations for interpreting wait event data and resolving high wait times through methods like tuning SQL, improving I/O speeds, and reducing contention.
This document discusses key performance indicators (KPIs) for monitoring the health and resource utilization of Exadata database machines using Oracle Enterprise Manager. It defines 10 metric extensions to monitor storage servers, including metrics for I/O operations per second, throughput, response time, load, and composite metrics to evaluate overall disk health. Instructions are provided on creating these metric extensions in Enterprise Manager using SQL queries and setting initial warning and critical thresholds. The document also covers Exadata and storage server architecture and explains how to monitor components holistically using these defined KPIs and Enterprise Manager services.
This document provides a system capacity plan for Company's new architecture. It determines the server, memory, and disk capacity requirements for the production, user learning, and testing environments to support the Oracle applications and business volumes over the next 3 years. Key results found sufficient initial capacity for cutover but identified future upgrades that may be needed. It also specifies desktop client machine requirements.
This document describes a visualization technique for SQL tuning called Visual SQL Tuning (VST). VST involves drawing the tables involved in a SQL query as nodes and the joins between the tables as connecting lines to show the relationships. It also identifies any filter conditions in the WHERE clause marked on the relevant tables. This visual representation of the tables, joins, and filters can help identify the optimal execution path for the SQL query.
This document introduces several concepts for tuning SQL queries, including modifying the join order, join method, and access method. It discusses using hints, statistics, and initialization parameters to influence the execution plan and cause the database to run queries more efficiently. Examples are provided for improving a sample query that joins multiple tables using different techniques.
The document discusses how database optimizers can sometimes provide incorrect cardinality estimates that result in inefficient query plans. It provides four examples of cardinality errors caused by uneven data distributions. The key strategies for addressing cardinality problems are: 1) giving the optimizer more statistical information through histograms and SQL profiles, 2) overriding optimizer decisions with hints, and 3) changing the application design/data model. Providing more information to the optimizer usually improves plans without additional code changes.
The document describes Active Session History (ASH), a new methodology for performance tuning introduced by Oracle. ASH simplifies performance tuning by using statistical sampling to collect session state and resource usage data over time. This provides a multidimensional view of sessions, SQL, users, objects, and waits consuming resources. ASH replaces previous methods that collected complete data at infrequent intervals, obscuring problems. Its sampling approach is cheaper, faster, and provides a good representation of the workload. The document outlines how ASH data can be used to identify top resource consumers and troubleshoot issues.

Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
