  • Exceptional Database Exceptions in Foglight

    A common question is how to make an exception for 1 or 2 particular databases for certain rules in Foglight. A good example is the "days since last backup" rule for SQL Server. The global default applies to all databases. It's possible from the Databases dashboard to change the setting for a particular instance, or to add a database to an exclude list, but an exception to the default can't be done there.…

    For a quick refresher, please see User Defined Collections in Foglight for SQL Server: A Quick Walk-Through

    With a "simple" UDC that returns a single value, adding it to a dashboard or report is a matter of finding it in the data model, and dragging it over. But what happens with a query that…

  • Reporting on Changes to Foglight Registry Variables

    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?

    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…

  • Evaluating Foglight vs Oracle Enterprise Manager

    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?

  • Foglight.. Start Your Engine!

    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.

    You may wonder what the startup process is doing. Or not. If you're in the former group, you can click the lower part of the…
