For evaluating Site performance and quantifying service popularity, System Log Parser (SLP) has several report offerings to conduct ArcGIS Enterprise log analysis. When selecting Analysis Types such as Simple, WithOverviewCharts or Complete, there is an
option called "Add Statistics By User to Report" which will include an additional worksheet called Statistics By User into the generated report. The information on this worksheet includes a statistical summary
of successful Portal member requests (as reported by ArcGIS Enterprise). This can be quite helpful for GIS administrators to understanding who is asking for what.
Sometimes however, the listed User on this worksheet may show the value of "anonymous". For a Site with secured services, this might be a puzzling username to observe. This Community Articles helps explains why this can occur.

The purpose of this article is to discuss strategies and concepts for using a JMeter Test Plan to exercise branch versioning editing. The test takes a programmatic approach for creating and capturing the data of important key/value pairs for several of the critical requests.
While a GIS editing test can be complicated since there are many moving parts to keep track of, this Article attempts to simplify the process as much as possible.
The tested workflow utilizes the Natural Earth dataset that is published as a web feature layer with branch versioning enabled.

This article describes a process for GIS and IT to collaborate to configure F5's BIG-IP to provide access to  an ArcGIS Enterprise deployment.  The goal of the article is share some of the foundational concepts for a "basic" case.  "Basic" does not mean "simple", however.  This configuration objective involves understanding and using many advanced concepts from several different information domains.

Optimizing the ArcSOC instance availability and utilization for your service is a good strategy for helping users obtain fast response times and lower wait times from their dynamic requests to your Site. It can also benefit server resource utilization like memory as the service is not running a lot of instances that it will never use.

But optimizing the minimum and maximum number of instances for your dedicated services is not a one-time job. Usage patterns of your services can change over time so the task of collecting this information is something that you will want and to revisit periodically as a GIS administrator.

Before diving into how to observe ArcSOC instance activity statistics, let’s review some of the key details of the two ArcSOC-based service types in ArcGIS Server and how they play into this discussion:

  • Dedicated
  • Shared

Measured transaction throughput and response times are critical data of any ArcGIS Enterprise load test, but captured hardware utilization of the deployment machines provide vital information as well. Together, these test artifacts allow for the proper analysis of the capabilities and efficiencies of the Site.

Determining that an application or feature service has achieved a particular level of throughput is good, but confirming the scalability characteristics while also examining the captured processor utilization of the tested workload is even better.

This Article will discuss several ways to capture the machine hardware utilization. This resource usage is a great compliment to the results of an Apache JMeter load test of ArcGIS Enterprise and can help further the analysis. The Article will focus on the most common scenarios using free tools and utilities for Windows and Linux.

Looking for a quick way to summarize the details of all your ArcGIS Enterprise services? If so, then System Log Parser's ServiceDetails Analysis Type is highly recommended. This feature performs a scan of your Site through the REST Admin API and presents the gathered information into a spreadsheet report for easy digestion.

The report is a great resource to find details on your service provider statistics, service configuration info, or data source analysis.

The System Log Parser (SLP) utility is great for being able to analyze many different "ArcGIS Enterprise" log sources to help quantify the usage of your Site. It is free and includes an easy-to-use graphical user interface (GUI) called SystemLogsGUI.exe. But, did you know it can also be run from the command line via the slp.exe that is included with the download?
Command line capable execution makes a good fit for automation through PowerShell or good old fashioned bat scripts.

The slp.exe executable includes all of the same capabilities. However, you can override many of the limits imposed by the GUI such as: the end time and start time. You can even access features that are not available from the GUI like: searching with specific UTC dates, customizing the name of the report, and enabling the application debug log (for troubleshooting).
