      Development, new applications, upgrades, patches, maintenance, schema updates…the list goes on and on around ways that changes are introduced into your environment.

    • Diagnosing Historical Sessions in SQL Server TempDB

      19 Apr 2018
    • In the recent release of Foglight for SQL Server, a change was made to the TempDB drilldown. Specifically, the Sessions tab would formerly show the current sessions, regardless of the time range selected on the dashboard. Now, it will allow you to drilldown to the sessions that had activity in TempDB during the desired time range.

      To start, drilldown to the Databases dashboard, select TempDB (1), select your…

    • Reporting on Changes to Foglight Registry Variables

      6 Apr 2018
    • Registry variables in Foglight are mostly used as placeholders in rules in order to avoid hard-coding in values. 

      For example, a rule to check cpu utilization over a certain percentage could be coded as:

      1- #utilization# > 99.0


      2- #utilization# > registry(cpu_high)

      The registry variable "cpu_high" would have a default value, and could be changed as needed. We would change it once on the Manage Registry Variables…

    • Do you have sensitive database rules?

      23 Feb 2018
    • You say “No” - well - I say “Yes”. All database rules are sensitive and have a sensitivity level.

      What does that mean? What is a sensitivity level? Where can I find it and can it be modified?

      Ok - a lot of questions, so let's start with the details.


      What is a sensitivity level?

      A sensitivity level is a template that defines which rule condition is being triggered. Different levels are available…

    • Foglight for Databases Quick Tip - Using the Workload Column in the SQL PI Dashboard

      13 Feb 2018
    • Naturally, it's VERY important to know when things are going wrong with our monitored instances. What's not helpful is the dreaded "False Positive." You know the scenario I'm about to describe. It's 03:00 and you're sleeping soundly and dreaming of the yacht you'll be sailing during your retirement. Suddenly, you're awakened by an alert that your instances are unavailable! During your fight for consciousness you start…

    • Evaluating Foglight vs Oracle Enterprise Manager

      2 Feb 2018
    • As part of most any database monitoring software evaluation, it includes comparing that software to similar solutions. Logically, it often means doing head-to-head comparisons to database tools that come bundled with that particular DBMS. Regularly, I see evaluators take note of similarities and differences of architecture, usability and navigation, and product features that present specific information to help address…

    • Monitoring the Status of your TempDB using Foglight for SQL Server

    • In every SQL Server instance the TempDB database is the common global resource for all the operations taking place and DBA's are particularly cautious about the use of it.  Given the nature of applications and ad-hoc queries by users, one must keep track of the usage of the TempDB by various applications and process and take appropriate actions when the size falls below a certain limit.  To ensure optimal health of…

    • When reporting a Foglight connectivity issue, support people are always asking to test the connection using Telnet or Putty. But what to do if you do not have Telnet or Putty installed?

      There are some other options, for example using an Internet browser or running command line tools like curl or netcat.

      So let’s start with the browsers. To test the connection you type in the address line:


    • Foglight.. Start Your Engine!

      15 Jan 2018
    • This post is short but hopefully useful. When you start the Foglight server and navigate to the home page URL (http://foglight_server:8080 or https://foglight_server:8443), you may see a startup splash page (below). If you see a login page, then the Foglight server has started and is ready to use.
