Monitor, diagnose, and troubleshoot Azure Storage. Overview. Diagnosing and troubleshooting issues in a distributed application hosted in a cloud environment can be more complex than in traditional environments. Applications can be deployed in a Paa. S or Iaa. S infrastructure, on premises, on a mobile device, or in some combination of these. Typically, your applications network traffic may traverse public and private networks and your application may use multiple storage technologies such as Microsoft Azure Storage Tables, Blobs, Queues, or Files in addition to other data stores such as relational and document databases. To manage such applications successfully you should monitor them proactively and understand how to diagnose and troubleshoot all aspects of them and their dependent technologies.

The diagnostics information you obtain from both monitoring and logging will help you to determine the root cause of the issue your application encountered. This week on HakTip, Shannon pinpoints an exploitation using Wireshark. Working on the shoulders of last weeks episode, this week well discuss what.

Then you can troubleshoot the issue and determine the appropriate steps you can take to remediate it. Azure Storage is a core Azure service, and forms an important part of the majority of solutions that customers deploy to the Azure infrastructure. Azure Storage includes capabilities to simplify monitoring, diagnosing, and troubleshooting storage issues in your cloud based applications. Note. The Azure Files does not support logging at this time. For a hands on guide to end to end troubleshooting in Azure Storage applications, see End to End Troubleshooting using Azure Storage Metrics and Logging, Az. Copy, and Message Analyzer. Introduction. This guide shows you how to use features such as Azure Storage Analytics, client side logging in the Azure Storage Client Library, and other third party tools to identify, diagnose, and troubleshoot Azure Storage related issues. This guide is intended to be read primarily by developers of online services that use Azure Storage Services and IT Pros responsible for managing such online services. The goals of this guide are To help you maintain the health and performance of your Azure Storage accounts. To provide you with the necessary processes and tools to help you decide if an issue or problem in an application relates to Azure Storage. To provide you with actionable guidance for resolving problems related to Azure Storage. How this guide is organized.

TrustWaves vulnerability scanner fails a scan due to a Windows 10 machine running RDP Block cipher algorithms with block size of 64 bits like DES and 3DES. The section Monitoring your storage service describes how to monitor the health and performance of your Azure Storage services using Azure Storage Analytics Metrics Storage Metrics. The section Diagnosing storage issues describes how to diagnose issues using Azure Storage Analytics Logging Storage Logging. It also describes how to enable client side logging using the facilities in one of the client libraries such as the Storage Client Library for. NET or the Azure SDK for Java. The section End to end tracing describes how you can correlate the information contained in various log files and metrics data. The section Troubleshooting guidance provides troubleshooting guidance for some of the common storage related issues you might encounter. The Heavenly Man. The Appendices include information about using other tools such as Wireshark and Netmon for analyzing network packet data, Fiddler for analyzing HTTPHTTPS messages, and Microsoft Message Analyzer for correlating log data.

Monitoring your storage service. If you are familiar with Windows performance monitoring, you can think of Storage Metrics as being an Azure Storage equivalent of Windows Performance Monitor counters. In Storage Metrics you will find a comprehensive set of metrics counters in Windows Performance Monitor terminology such as service availability, total number of requests to service, or percentage of successful requests to service. For a full list of the available metrics, see Storage Analytics Metrics Table Schema. You can specify whether you want the storage service to collect and aggregate metrics every hour or every minute. For more information about how to enable metrics and monitor your storage accounts, see Enabling storage metrics and viewing metrics data. You can choose which hourly metrics you want to display in the Azure portal and configure rules that notify administrators by email whenever an hourly metric exceeds a particular threshold. For more information, see Receive Alert Notifications. The storage service collects metrics using a best effort, but may not record every storage operation. In the Azure portal, you can view metrics such as availability, total requests, and average latency numbers for a storage account. A notification rule has also been set up to alert an administrator if availability drops below a certain level. From viewing this data, one possible area for investigation is the table service success percentage being below 1. Metrics show low Percent. Success or analytics log entries have operations with transaction status of Client. Other. Errors. You should continuously monitor your Azure applications to ensure they are healthy and performing as expected by Establishing some baseline metrics for application that will enable you to compare current data and identify any significant changes in the behavior of Azure storage and your application. The values of your baseline metrics will, in many cases, be application specific and you should establish them when you are performance testing your application. Recording minute metrics and using them to monitor actively for unexpected errors and anomalies such as spikes in error counts or request rates. Recording hourly metrics and using them to monitor average values such as average error counts and request rates. Investigating potential issues using diagnostics tools as discussed later in the section Diagnosing storage issues. The charts in the following image illustrate how the averaging that occurs for hourly metrics can hide spikes in activity. The hourly metrics appear to show a steady rate of requests, while the minute metrics reveal the fluctuations that are really taking place. The remainder of this section describes what metrics you should monitor and why. Monitoring service health. You can use the Azure portal to view the health of the Storage service and other Azure services in all the Azure regions around the world. This enables you to see immediately if an issue outside of your control is affecting the Storage service in the region you use for your application. The Azure portal can also provide notifications of incidents that affect the various Azure services. Note This information was previously available, along with historical data, on the Azure Service Dashboard. While the Azure portal collects health information from inside the Azure datacenters inside out monitoring, you could also consider adopting an outside in approach to generate synthetic transactions that periodically access your Azure hosted web application from multiple locations. The services offered by Dynatrace and Application Insights for Visual Studio Team Services are examples of this outside in approach.
