From Wikipedia, the free encyclopedia:

In computing, syslog is a standard for message logging.

Executive Summary

vRealize Log Insight, part of comprehensive vRealize suite of applications from VMware is a modern log management and analysis application. With its easy installation, intuitive user interface, high level of customization and integration with other VMware as well as third-party products, vRealize Log Insight presents an attractive solution for customers interested in monitoring and troubleshooting their virtualized, cloud-based environments. To deliver extendibility and simplify third-party product integration, vendors may develop Log Insight Content Packs. This document focuses on the Pure Storage Content Pack, its installation, configuration, and use cases.


Pre-sales consulting engineers, sales engineers and customers who are interested in deploying or already have deployed the Pure Storage FlashArray in VMware vSphere-based virtualized datacenters utilizing Log Insight are the intended audience for this article. No extensive Log Insight knowledge is required however, basic familiarity with FlashArray and Log Insight is necessary. For vRealize detailed documentation refer to


VMware vRealize Log Insight provides centralized, real-time log administration for heterogeneous environments that span across physical, virtual and cloud environments. By directing the standard syslog messages to be processed by vRealize Log Insight, administrators can easily gain insight view to their environment for monitoring, analysis and troubleshooting. Custom queries and aggregations add structure to machine-generated log data making it simpler to parse and query, custom dashboards, reports, alerts, interactive searches provide additional tools for enhanced infrastructure operational efficiency. Third-party product integration is achieved by Content Packs.

Content Packs

VMware vRealize Log Insight allows partners to create read-only integration plugins referred to as Content Packs. Content Packs provide additional intelligence into Log Insight and are developed by partners. Generally, Content Packs include custom queries, dashboards, alerts and fields. These custom properties are created in context of the source system sending syslog messages. The important metrics, events and alerts along with field descriptions are already defined in the Content Pack therefore, significantly reducing initial Log Insight configuration.

Pure Storage Content Pack


The Pure Storage Content Pack offers a variety of dashboards, widgets, queries and alerts specifically tailored to provide means of processing FlashArray generated syslog messages and notifying IT administrators of potential as well as existing system issues. Log Insight widgets deliver easy to visualize and decode query results. Widgets are logically group into dashboards. Besides providing customized dashboards, widgets, alerts and queries, Pure Storage Content Pack also includes extracted fields. Extracting and describing fields gives structure to unstructured syslog messages allowing for meaningful message parsing and data analysis. Pure Storage Content Pack is freely available for Pure Storage customers.


  • vRealize Log Insight 4.5 or higher
  • Purity 4.8 or higher


The Pure Storage Content Pack can be installed directly from vRealize Log Insight Content Pack Marketplace. If the Internet access from vRealize Log Insight is not possible, the Content Pack may be downloaded from VMware Solution Solution Exchange web site at and installed manually. See Figure 1.


Figure 1.

Once Pure Storage Content Pack is successfully installed, it can be located in the left pane of the Dashboard window under Content Pack Dashboards.

FlashArray Configuration

FlashArray has a built-in syslog logging facility however, the storage system must be configured to forward messages to remote syslog servers such as vRealize Log Insight. The configuration may be done using command line interface or Graphical User Interface.

Command Line Interface

To forward syslog messages to remote syslog server (vRealize Log Insight) execute purelog command on FlashArray:

purelog create --uri URI NAME

where URI is a the URI of the remote syslog server and NAME is syslog server identification used by Purity.

The URI format is:


The NAME parameter is optional. vRealize Log Insight supports UDP and TCP protocols using port 514 and 1514, 6514 for TCP SSL connections.

for example:

purelog create --uri udp://

Syslog configuration can be tested using the following command.

purelog test 

Graphical User Interface

To forward syslog messages to remote syslog server (vRealize Log Insight) using Graphical User Interface navigate:

Settings ➤ System  ➤ Syslog Servers  ➤ Provide URI for syslog server  ➤ '+' (plus sign)

Send a test message by selecting Test button.


Figure 3.

Successful transmission needs to be verified using Log Insight. Select Interactive Analytics and in the query field enter flasharray, optionally a second text query may be added by choosing + ADD FILTER with condition contains word test. The query will return pure_event_type test with This is a test message generated by Pure Storage FlashArray text.

Result of successful transmission is shown in Figure 4.

Using Pure Storage Content Pack


The structure of Pure Storage Content Pack provides a logical workflow for FlashArray management. Each dashboard consists of multiple widgets which provide easy to view and scan means of quickly obtaining FlashArray releated data. This data is intended to assist in maintaining, monitoring and troubleshooting vSphere FlashArray-based back-end storage. Besides the quick overview delivered by each widget, vSphere administrator can easily examine detailed information about FlashArray related events reported to Log Insight.

For instance, based on Figure 5, the sn1-405-c12-13 FlashArray reported seventeen critical alerts.


Figure 5.

By switching to Alerts dashboard, Critical Alerts By Array and Critical Alerts - Details widgets, detailed data for each critical alert can be obtained by mousing over the appropriate graphic (bar or doughnut) or Interactive Analytics, click Open in Interactive Analytics icon on corresponding widget. See Figure 6 and Figure 7.

Extracted Fields

Extracted fields describe syslog message fields simplifying the process of searching, identifying and understanding the content of FlashArray generated events. Log Insight provides a comprehensive set of indicators to describe a field which are called regular expressions. Generally, FlashArray messages follow a certain pattern which can be searched using regular expressions. The Pure Storage Content Pack provides forty extracted fields. Details of each described field including regular expression can be viewed from Log Insight Content Packs pane. See Figure 8.


Figure 8.

Extracted fields are also displayed in Interactive Analytics where Log Insight automatically highlights associated part of FlashArray syslog message when mousing over the extracted field. See Figure 9.
