To run a Monitored Subjects Detail Report, select Tools > Monitored Subjects Detail Report from the Live Exceptions Browser menu.

The report lists the elements in the selected group or group list that is being monitored by rules in a profile. The name of the subject being monitored and its technology type appear at the top of the report (for example, Subject: Myservers (Server Group)). The report shows the elements in a group or group list, the rules that apply to each element, any rules that do not apply, and any rules that are disabled. For group lists, the report lists the information for each group in the group list.

The report consists of five columns which are:

    • Element Name - Name of the element. This will include all elements in the group and will list their element names or alias names depending on web user permissions. In the case of groups such as System or Router groups, where only the parent element can be added to a group, all children elements will be listed as they are also applied to the same rules the parent elements are by way of the parent/child element relationship.

    • Monitor - This value will be either Yes or No. It relates to the field within the Poller Configuration Modify UI for an element labeled "Live Exceptions: Monitor" with a checkbox. When the checkbox is checked, the element will be monitored with LE and will show a Yes in this column. Conversely, it will show a No and not be monitored by LE if the checkbox is not checked.

    • Profile - This is where the name of the profile will appear. There will be entries for every profile associated to the selected group listed in this column.

    • Rules That Apply - This will show which rules are applicable to the elements and which are capable of generating alarms in LE

    • Rules That Do Not Apply (due to undefined variables or disabled rules) - This column will show which rules are not applicable to the elements, and which are not capable of generating alarms in LE

    Reading of the LE Monitored Subjects Detail Report can be broken down and defined in three steps or parts.

      • Elements with no rules that appear in either the "Rules That Apply" or "Rules That Do Not Apply" columns

      • Elements with rules that appear in the "Rules That Do Not Apply" column

      • Elements with rules that appear in the "Rules That Apply" column

      Part 1 - Elements with no rules that appear in either the "Rules That Apply" or "Rules That Do Not Apply" columns
      When creating an LE Alarm Rule, one of the first steps is specifying an Element Type that the rule should apply to. If this choice is different than the element being reviewed, then this is how it will appear in the Monitored Subjects Detail Report. For instance, a rule with an Element Type of "Disk Partition" would not apply to a servers ethernet port element. To resolve this, take the target rule that is not appearing as applicable to the target element and modify it's Element Type value to something that is a closer match to the elements Element Type. This may take a small amount of trial and error as the Element Types defined in an elements Poller Configuration Modify UI do not match the list presented in the LE Rule Modify UI. An easy way to get a good idea of what Element Type to use for a target element is to see which Element Type would need to be selected to make that element available to run a report against via the eHealth web. Sometimes there is only one option, for instance Router/Switch. In the LE Rule Modify UI Element Type selection field, there might be a longer list of options. I.n this field, in the Router/Switch example in LE, the options are:

           Generic Router/Switch
           Router/Switch with CPU
           MW Router
                Winphoria Active Directory
                Winphoria Control Switch

      In this case, while the Router in question might have a CPU, the better choice would be to start simple at the top level "Router/Switch", get the rule in either the Rules That Do or Don't Apply columns. Once the Element Type has been properly selected, and the rule is showing in the Rules That Do or Don't Apply columns, now we can move on to parts 2 and 3.

      Part 2 - Elements with rules that appear in the "Rules That Do Not Apply" column
      When a rule appears in this column for an element, it is there for one of two reasons.

          • The rule has been disabled

          • The variable selected for the rule is undefined

          The first one is the simplest to check and resolve. When a rule has been disabled, when it appears in this column, it will specifically state "(Disabled)". To resolve this, simply go into the particular rules LE Rule Modify UI and Enable the rule.

          The second one requires the understanding that not all elements of the same Technology Type are going to support the same statistics and variables. For instance, the variables available for reporting are going to be different for a Unix System when compared against a Windows System. When creating an LE Rule, it is not yet associated to an element type, so when choosing a variable after selecting an Element Type during rule creation, the user is presented with a full list of all possible variables. In the example of Unix vs. Windows Systems, you would get both full sets of variables. To resolve this, we need to utilize a feature of the eHealth Web UI Run Reports interface. Take the particular element in question, and choose it within the setup of a Standard Trend Report via the eHealth Web UI. Now the variable list will appear as the same as that seen in LE. To narrow the list down to only variables applicable to the target element, select the "Validate Variables" button. This is the list of supported variables for the target element. Note that the variable listed in the "Rules That Do Not Apply" column is not present. Change the variable in the rule that is appearing as not applicable, to one that is applicable. In the end, when it states that this is due to the variable being undefined, this is stating that the variable does not have data collected from this element for one reason or another (some of these would be the device does not support it, or the eHealth is not polling the data for that variable).

          Part 3 - Elements with rules that appear in the "Rules That Apply" column
          If a rule appears in this column for a target element the Element Type selected is correct for the target element and the variable selected is available to the element.
