Foglight 7.3.0 - Administration and Configuration Guide

Cyclic Maintenance

Each of the following tasks helps to ensure that the Foglight® Management Server is stable and is operating normally.

Assuming you automate self-monitoring as described in Recommended Self-Monitoring Automation, there is no need to perform the checks described below.

If you do not have automated self-monitoring in place, you must use the manual technique below, performing each item at least once daily.

For context on the key resource requirements and their effect on the Foglight Management Server, see the Foglight Performance Tuning Field Guide.

Perform the following tasks once every week:

Perform the following tasks manually, once every month:

Using a single pane of glass for your administration needs

The Administration dashboard can be used as a front-end for most Foglight® administration tasks. This dashboard contains links to most of the administration dashboards and shows configuration specifics that may be critical to your day-to-day operation. If your Foglight role involves daily administration, this is probably the best place to start as it gives you a quick insight into the system complexity and its health, along with close-at-hand links to most administration dashboards.

You can access this dashboard from the navigation panel, by clicking Homes > Administration.

In addition to the administration dashboards accessible from the Administration home page and the Administration node on the navigation panel, Foglight includes another set of administration-level dashboards that can be used to analyze logs, monitor the server performance, and service levels. These dashboards are described in this section.

Manage Foglight Database Performance

In Foglight, retention policies define time periods during which the collected data is sampled, persisted into the database, aggregated, or purged from your system. The Object Cleanup dashboard is useful for inspecting, purging, and deleting data objects, and particularly for cleaning up objects that are no longer needed. For instance, if a set of agents is no longer required, the objects created by those agents are still visible in the browser interface. Removing these objects can have a positive impact on performance.

NOTE: In previous releases, the Data Management dashboard allowed you to manage both retention policies and object cleanup. Beginning with Foglight 6.3.0, there are now two separate dashboards: • Retention Policies • Object Cleanup

Using these dashboards you can manually tune the size and performance of your environment. Tuning performance manually allows you to:

To access this dashboard, from the navigation panel, click Dashboards > Management Server > Servers. Then select either Object Cleanup or Retention Policies.

Another way to control the retention policies on a per-object basis is using the Manage Retention Policies dashboard. For more information, see Manage Data Retention.

In addition to the Object Cleanup and Retention Policies dashboards that allow you to inspect and tune the overall performance, the Database Overview dashboard summarizes the database activities such as data row operations, database buffer pool, and any inserts, deletes, and updates. To access this dashboard, from the navigation panel, click Dashboards > Management Server > Servers > Database Overview.

Monitor Server Performance

Foglight manages host data sent from agents, and evaluates rule conditions and metric calculations. It also provides browser interface access to remotely monitored servers. The browser interface includes a set of dashboards that allow you to monitor the server state and prevent potential bottlenecks.

The Performance dashboard contains at-a-glance view of Foglight diagnostics. It shows the rate of database inserts, data processing activity, JVM memory usage, server load, and other combinations of views. Certain types of metric patterns displayed on this dashboard can be useful in troubleshooting specific performance problems. For example, a sudden increase in free memory utilization is a good indicator that the amount of incoming data exceeds typical thresholds. To access this dashboard, from the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.

The Management Server View dashboard is useful for examining server performance. Use it to look for root causes of server-related performance problems. To access this dashboard, from the navigation panel, click Dashboards > Management Server > Servers > Management Server View.

Server log files are another source of information that can help you diagnose the root cause of performance-related bottlenecks. They contain information about known events and error conditions as well as verbose or informational messages. The Log Analyzer dashboard allows you to analyze generated log files or download a selected log file to a desired location. To access this dashboard, from the navigation panel, click Dashboards > Management Server > Diagnostic > Log Analyzer.
