Foglight 7.1.0 - User Guide

Viewing the host performance

The CPU, Memory, Disk, and Network columns allow you to obtain a concise overview of your hosts’ performance in these metric categories. The values in these columns—and the popups and drilldowns available from them—change with the dashboard's time range.

These columns display recent and current values for each metric category. Recent values are displayed as a sparkline in the Utilization column.

 
* 
TIP: By default, a sparkline is shown only in the CPU Utilization column. To display sparklines for other metric categories, click the Show columns icon () at the top of the table and select the Utilization checkbox under Memory, Disk, or Network.
To investigate a host’s CPU-, memory-, disk-, and network-related performance:
1
Hover the cursor over the sparkline or current value in the CPU, Memory, Disk, and Network column for that host.
A popup appears. It contains a utilization chart for that metric.
2
To investigate further, click the sparkline or current value.
A dashboard appears that contains details for that metric category.
 
* 
TIP: Hover over a line or area in a chart to display data for the nearest time in a tooltip.

CPU

CPU Details (example shown below): use it to identify the top CPU consumers on the host, see the top processes’ utilization trends, and view charts for CPU utilization process load.

Memory

Memory Details: use it to investigate overall memory utilization on the host and the amount of memory the top processes are consuming. The Top Memory Consumers table lists both resident and virtual sizes for the top processes.

Disk

Disk Details: use it to identify the top disk I/O consumers on the host, see the utilization trends of the top CPU processes, and view charts for disk size and bytes read and written.

Network

Network Details: use it to investigate the aggregate network utilization of the host and view the activity of your network connections.

Viewing dependencies for a host

You can view the dependencies for a selected host you are monitoring in the Host Monitor dashboard by clicking Host Dependencies on the General tab of the action panel. If you have the Cartridge for Dependency Mapping installed, this feature allows you to view the elements in the host’s dependency chain.  For more information, see the Managing Dependency Mapping User Guide.

Determine if the state of a host impacts your services

If one of your hosts is in a state other than Normal (), use the impacted services popup to view which of your services that host might impact. This popup helps you establish whether critical services are affected by problems with your hosts and decide if immediate action is necessary to resolve these problems.

* 
NOTE: You can only view user-defined impacted services. System services are not shown.
To view a host’s impacted services:
•
Click the icon () in the Impacted Services column for the host you are investigating.
The impacted services popup shows a summary that lists the name of the impacted service, its aggregate state, and its aggregate state history.
 
* 
NOTE: The Service Health History column is hidden by default. To view it, click the Show columns icon () and then select the column in the popup.
 
* 
TIP: In addition to the dashboards described in this chapter, Foglight provides you with other views on your hosts. For details, see the online help for the dashboards listed under Dashboards > Hosts in the navigation panel.

Reporting on Your Enterprise

Reports are a convenient way to share data about your monitored environment with others in your organization. The Reports dashboard is your starting point for working with reports. Use it to create and schedule reports and to access the Manage Reports dashboard. You can create:

•
Pre-defined reports. Use out-of-the-box templates to obtain a quick, high-level perspective on your data. See Running a Report .
•
Custom reports. Create custom report templates to tailor the content and presentation of your reports to suit your needs. See Building a Custom Report .

The Report Manager role allows users to schedule as well as generate the reports for which they have role access. It is different from the Operator role, for example, in that users granted the Operator role can generate reports but cannot schedule them. With the Report Manager role, users cannot create new report templates through the Definitions editor or create reports using the drag and drop feature initiated from the action panel. The Advanced Operator role grants users access to all report functionality.

 
* 
NOTE: You can also access this dashboard from the navigation panel: select Homes > Reports.
Figure 1. The Reports dashboard.

The Reports dashboard also provides at-a-glance reporting details. It displays the number of report templates available to you, the number of scheduled reports, and information about upcoming scheduled reports and recently generated reports.

A Reports menu is located at the top-right corner of each dashboard. From this menu, you can quickly create a new report, run a report, and manage reports. You can access the same menu from the General tab on the action panel by expanding Other Actions and clicking Reports.

Running a Report

Foglight contains a number of pre-defined report templates. Each template serves a particular purpose, but many templates have the same expected inputs. The values you specify for these inputs define the content of the report.

Use a template as-is to quickly generate or schedule a report, or change the report input values to meet specific requirements.
