Behind the alarms window is the monitor home page (see Figure 9). If no alarms exist in the environment, then this is the first page that will be displayed in the monitor interface.
Figure 9 : The Monitor Home page
This page quickly updates a user with the health of his/her monitored environment. The page reveals the following information:
The table below explains the color-coding scheme adopted by eG for indicating the states of the services/segments/components:
Color | State |
---|---|
Red |
Critical |
Orange |
Major |
Yellow |
Minor |
Green |
Normal |
Blue |
Unknown |
If you click on a division in the Zones doughnut graph, you will be lead to a page that lists the zones which are in that particular state (see Figure 10).
Figure 10 : The zones in a particular state
Against every zone in this page, the infrastructure elements (which could be subzones/segments/services/components within a zone) that are part of the zone, and the current state of each element will be listed (see Figure 10).
Note:
By default, against each zone displayed in the zone list page, the top-10 Components included in that zone will be displayed. Typically, to identify the top-10 components, eG Enterprise automatically sorts all the components included in the zone on the basis of their current state, arranges the sorted list in the alphabetical order of the component names, and picks the first 10 components of this list.
If you want more number of components to be displayed against each zone, do the following:
Clicking on the Zones link in the Infrastructure Health section reveals the complete list of configured zones and their state.
Note:
While listing the Components associated with a zone, if you want the component-types listed instead of the component names in Figure 6, then you will have to set the Display component types in segment/service list flag in the monitor settings page of the eG administrative interface, to Yes.
Clicking on an abnormal component in Figure 10 will lead you to a page that displays the layer model, tests, and measurements of the component. Clicking on a zone Figure 10, reveals a Zone Dashboard that summarizes the performance of all the zone elements. For more information on the zone dashboard, refer to Service Health of this manual.
Clicking on a division in the Service Groups doughnut graph will lead you to a page that lists the service groups, which are in that particular state.
Clicking on a division in the Services doughnut graph in the Infrastructure Health section will lead you to a page that lists the services, which are in that particular state (see Figure 11). By default, against every service in this page, the components engaged in the delivery of the service will be displayed along with their state.
Note:
By default, against each service displayed in the service list page, the top-10 Components associated with that service will be displayed. Typically, to identify the top-10 components, eG Enterprise automatically sorts all the service components on the basis of their current state, arranges the sorted list in the alphabetical order of the component names, and picks the first 10 components of this list.
If you want more number of components to be displayed against each service, do the following:
Note:
By default, only the components associated with a service will be displayed in the service list page. If you want the segments associated with the service also to be displayed, then, do the following:
To make sure that service list page does not display the list of components associated with a service, set the Show component(s) in service list flag in the other display settings panel of the monitor settings page to No.
If both the segment list and component list are disabled, then the SERVICE LIST page will only display a vertical list of services and their current state.
Clicking on the Services link in the Infrastructure Health section reveals the complete list of configured services and their state.
Note:
While listing the Components associated with a service, if you want the component-types listed instead of the component names in Figure 11, then you will have to set the Display component types in segment/service list flag in the monitor settings page of the eG administrative interface, to Yes.
Figure 11 : Viewing the list of services in a particular state
Clicking on an abnormal component in Figure 11 will lead you to a page that displays the layer model, tests, and measurements of the component. Click on a service name in Figure 11 to view the topology of the service (in case of a non-web-site service) (see Figure 12) or the transactions configured for that service (in case of a web site service). However, if a problem service constitutes more than one problem segment, then clicking on the service name in Figure 11 will take you to a page that lists the problem segments, indicates the current state of each segment, and the problem components (if any) in every segment.
Figure 12 : The topology of the web site buy.abc.com
Next, to know how well every segment configured in the environment has fared, take a look at the Segments doughnut graph in the Infrastructure Health section. Clicking on a division in this graph will enable you to view the list of segments in a particular state (see Figure 12). Alongside each segment, the IP/hostname of the top-10 (by default) the segment components (i.e., components that are part of the segment) will be displayed along with their state.
Note:
By default, against each segment displayed in the segment list page, the top-10 Components included in that segment will be displayed. Typically, to identify the top-10 components, eG Enterprise automatically sorts all the components associated with that segment on the basis of their current state, arranges the sorted list in the alphabetical order of the component names, and picks the first 10 components of this list.
If you want more number of components to be displayed against each segment, do the following:
Note:
While listing the Components associated with a segment, if you want the component-types listed instead of the component names, then you will have to set the Display component types in segment/service list flag in the monitor settings page of the eG administrative interface, to Yes.
Figure 13 : The list of segments that are in a particular state
Click on a segment name in Figure 13 to view the topology of the segment. If you click on a component, then the layer model, tests, and measurements of that component will appear.
Clicking on the Segments link in the Infrastructure Health section reveals the complete list of configured segments and their state.
Finally, click on a division in the Components bar graph in Figure 9 for a quick update on components that are currently in a particular state.
Clicking on the Components link in the Infrastructure Health section reveals the complete list of configured components and their state.
Figure 14 : The components that are in a particular state
For a closer look at the issues affecting a component's performance, click on the component listing in Figure 13. The page depicting the problem layers, tests, and measurements of the chosen component will then appear.
Note:
By default, components that are newly managed will be in the normal state. The state will change as the agent starts reporting measures to the eG manager. You can change this default setting to ensure that newly added components are initially in the unknown state, instead of normal. To achieve this, set the NewTestsUnknown parameter in the [misc_args] section of the eg_services.ini (in the <EG_INSTALL_DIR>\manager\config directory) to Yes (the default value is No).
Also, there will be a 30 second time lag between when a component is managed and when its state changes to normal.
Below the Infrastructure Health section you will find a Measures At-A-Glance section that provides the min/max values of critical measurements updated in real-time. By default, using this section, you can quickly find answers to the following critical performance queries:
You can however, change this default setting to reveal more or less - i.e., you can add to the measure list displayed here, or remove a few measures from the displayed list. To achieve this, do the following:
The min/max values of the configured measures will then be displayed in the Measures At-A-Glance section of the Monitor Home page. The first column of the Measures At-A-Glance section in Figure 14 indicates the current state of the measure (whether Normal/Critical/Major/Minor/Unknown). The Measure column is where the configured measures will be displayed. Similarly, each of the configured tests will appear in the Test column. Besides, a Server column exists, which displays the name of the component and the descriptor, which has currently registered the maximum/minimum value (as the case may be) for every chosen measure. For example, in Figure 8, the tomcat process executing on the Generic server named generic, is the process that is currently consuming a lot of memory. Finally, the current value of the measures for the displayed components will be displayed in the Value column.
Note:
The measures will be displayed in the order of the configuration.
Using the information provided by the Measures At-A-Glance section, administrators can receive instant status updates on sensitive performance parameters, and can also accurately determine, at a glance, the component on which the parameter is currently experiencing issues (if any), thereby simplifying problem identification.
Clicking on the contents of any cell in this section, will lead you to the layer model of the corresponding component.
Optionally, you can even switch off the Measures At-A-Glance section. To do so, you will have to set the Compute top metrics parameter in the measures at-a-glance configuration page of the eG administrative interface to No. By default, this parameter is set to yes indicating that, by default, the monitor home page will contain the maximum/minimum computations for measures (i.e., the Measures At-A-Glance section). When it is set to no, the Measures At-A-Glance tab is hidden from the home page, and the Event Analysis tab alone appears.
The Event Analysis tab page, when clicked, lists the top-5 layers that were most affected by performance issues. Figure 15 depicts a sample monitor home page with the Event Analysis section.
Figure 15 : A Monitor Home Page with the Event Analysis section
Corresponding to every layer name in the Event Analysis section, you will see the number of alarms that are currently open for that layer, the average duration of the open alarms, and the maximum duration for which an alarm had remained open (see Figure 15). To the right of the tab page, you will find a list of components that experienced the most number of performance issues during the last one hour (by default). Against every component listing, the corresponding component-type, and the number of events the component encountered during the default period of one hour, is displayed. This information brings to light the most problem-prone components in the environment. Clicking on a component/component-type in this list, reveals the layer model, tests, and the last set of measurements that the eG agent reported for that component. To analyze events across a broader time window in the past, select a different timeline from the Components with most events in the last list box here.
The details available in the Event Analysis section serve as an effective indicator of the efficiency of the administrative staff in resolving performance issues. To view the complete history of alarms in the environment, click on the Click here for more events >> link.
The Components At-A-Glance section comprises of a bar graph depicting the number of components of each type that are being monitored, and their respective states. Clicking on a bar will take you to a page that lists the individual components of the corresponding type and their current state (see Figure 16).
Figure 16 : Viewing the list of components of a particular type
By clicking on each Server type in the Components At-A-Glance section, you can view all components of that type and their current state. For instance, clicking on Generic in the Components At-A-Glance section of Figure 16, will reveal all managed components of type Generic and their current state.
Note:
By default, in the Components At-A-Glance section, the component-types are sorted in the descending order of the total number of monitored components of every type - in other words, in the descending order of the values in the Count column of the section. To change the sort order - i.e., to sort the component-types in the ascending order of the contents of the Count column - simply click on the down-arrow icon next to Count. To sort by a different column, say, the Server Type column, simply click on the corresponding column heading. This will instantly sort the contents in the alphabetical order of the names of the displayed server types. You can even override the default sort order, so that the component-types are by default arranged in the alphabetical order of their names, and not on the basis of the Count. To achieve this, Click on the icon available in the Admin tab. Then, select the Monitor option in the Settings tile. In the OTHER DISPLAY SETTINGS section of the MONITOR SETTINGS page, set the Sort components in dashboards flag to By component types. This ensures that the contents of the Components At-a-Glance section are by default sorted in the ascending order of the component-types. Accordingly, the down-arrow icon, by default, appears next to the column heading, Server Type.
The menu at the top of this page permits monitor users to view the status of the monitored elements such as zones, Services, Segments, and individual components (see Figure 16).
