Sightline Enterprise Data Manager (EDM) 3.2

Sightline Systems is pleased to announce the release of Enterprise Data Manager (EDM) version 3.2. EDM 3.2 includes exciting new features and enhancements.

Alert enhancements 

  • You’ll be able to makes notes in the alert record to track the work being done to clear up the issue.
  • Modifications to alert definitions will now take effect without having to restart the connection.

Clairvor enhancements 

  • You can now navigate Event data on Clairvor reports (see below).
  • The default time range for the Clairvor analysis has been expanded.
  • We’ve added “signal strength” icons to indicate the strength of correlation; you can toggle between this and the Pearson’s r value.

Quick Chart Enhancements

  • A Quick Chart now displays Event data, and you can navigate the data back and forth (see below).
  • A scaling option has been added to charts, so that you can select to autoscale based on the highest value or provide a custom scale on chart definitions.

Report Enhancements 

  • You can now assign connections to each chart on a report individually, and you can assign different time ranges to each chart on a report.
  • On-the-fly report generation has been added to EDM, so that when the you click on a data source a default report will appear.
  • We’ve added printing for reports, with a printer icon that pops out the report in print mode. You can then use your browser print function to print the report.
  • We’ve dropped support for Adobe Flash; reports and charts are now HTML5.
  • The report refresh option no longer repaints the entire screen, resulting in a much faster refresh.
  • As with Quick Charts, we’ve added scaling to charts; you can elect to autoscale based on the highest value or provide a custom scale in the chart definition.

EDM UI updates

  • We’ve made significant performance improvements to the UI performance, including enhancements on report rendering.
  • The EDM UI has been localized for the Japanese market.


  • A Security Log has been added to EDM for tracking user actions. To view the log, click Settings-EDM Logs and then opening the security.log.


  • New default expressions have been added to EDM. This group of expressions is particularly useful for capacity planning purposes.

Navigating Event data in EDM

Sightline EDM 3.2 includes the ability to navigate through Event data process lists in Clairvor reports and Quick Charts. You can navigate to a point in time simply by clicking on the line in the graph and also use the navigation controls to move back and forth one data point at a time. This feature makes it easy to identify the process that is causing performance problems on your system.

You can use the left-arrow controls to navigate backwards 10% of the time range and interval-by-interval, respectively. Use the right-arrow controls to navigate forward interval-by-interval or by 10% of the plotted time range, respectively.To change the Event class that you are viewing, select it from the Event class drop down box. The columns of the Event class are sortable by clicking the column’s name. To view more Event rows, click the pop out window icon.

Tip: Clustering EDM Instances

This week’s Ask John question is from Oscar Jiminez at Megadata Information Solutions in Costa Rica. Thanks, Oscar!

Question: In an EDM high availability hypothetical scenario (2 EDMs working as active/active nodes), can both EDMs can share the same EDM DB? Under this scenario, I can put this database in a SQL cluster and provide it also high availability.

Answer:  Certainly. This implementation is supported; click here for an example of configuring JBoss with Apache HTTPD.

Sightline Support for ClearPath OS2200 CP 15.0

Unisys Corporation has announced the release of CP 15.0 for ClearPath OS2200 Systems. This feature-rich release includes DSTA, Daylight Saving Time Adapt. How this will affect your Sightline implementation? The current GA version of the Power Agent, version 7R8 on the SupportWeb downloads page, has been updated to address DSTA. If or when you upgrade your ClearPath system to 15.0, you will need version 7R8 of the Power Agent. You can upgrade now, as 7R8 is compatible with older versions of the OS.

For Torch users, Sightline has released version 4R7D to support CP 15.0.

Tip: Configuring Sightline EDM to Use SSL

Security is always a concern for IT teams. Sightline EDM has you covered by providing support for Secure Socket Layer (SSL) which secures your browser communications with the EDM Server. Click here for configuration details.

Understanding the Sightline Software Solution: Collect… Store… Inform…

There are three basic components to the Sightline Software Solution: data collection, data storage, and turning that data into meaningful information. Last week we looked at data collection. This week we will look at how Sightline stores the data.

After we collect the data we store it centrally in the Sightline Big Data Repository. Our Big Data Repository, like the rest of our software, is policy driven. We designed it this way to give you full control to determine what you do with the data after we collect it. You can easily configure how long to keep the data, when to dump it and when to archive it, to give you full control of your environment.

Summarization is done at the same time – you determine the summary interval and how long to keep the data at that interval. In fact, you can have multiple summary intervals, with different retention periods for each one. Remember that we only collect the data one time, so we only need to store it one time. We do this to keep the overhead down and not burden your systems with unnecessary waste. You can also feed the data to RDBMS or your message platforms for ticketing and other uses.

EDM Visualization With Zoom Line Charts

Sightline Enterprise Data Manager (EDM) includes many chart formats for displaying and analyzing your performance and capacity data. Using the zoom line chart, you can show thousands of data points at a time, and then either zoom in to examine a subset of that time span or “pin” a shorter time span and compare it to non-adjacent time periods.

Pinning data to compare time spans

Start by creating a chart that covers your total time span. For instance, this chart displays Disk % Busy for five days (February 2-6).

Switch to Pin mode in the zoom line. You can then highlight a section of the chart to visually compare to other sections of the chart. In this example, we selected the day of February 3, from midnight to midnight.

Then, drag it over the other days to see the comparison with their performance or trend. You can click-and-drag the selected time, or use the arrows to move one data point at a time.

Sightline releases EDM 3.1 with Clairvor for Automated Root Cause Analysis

Sightline Systems is pleased to announce the general availability of Enterprise Data Manager (EDM) version 3.1. Sightline EDM provides centralized data collection, alerting, archiving and summarization for data collected by Sightline Power Agents and Interface Agents. EDM also provides a web-based interface for data visualization, root-cause analysis and and Agent administration and configuration

EDM 3.1 contains exciting new features, including Clairvor for automated root cause analysis. Clairvor provides faster root cause analysis, insight into active processes, and automated correlation. In just a few clicks, you can do what took minutes or hours in the past.

Tip: Installing the Linux Power Agent as a Non-Root User

The Sightline Power Agent for Linux Systems is required to be installed from a user with full root access. However, this is not always possible. This document provides steps to grant root privileges to non-root users, so that they can install and run the Sightline Power Agent on Linux systems.

Tip: Monitoring Real Memory Utilization in Linux

Linux uses RAM memory for disk caching to speed up the system. This means that the Mem % Free metric will consistently be low, perhaps 5%, when the system is actually only using 50% of the RAM. In Sightline, this real usage can be monitored and alerts can be created to alert you if the amount of real memory goes too low.
