Generating reports

Generating reports

Foglight for VMware includes a report generation ability. This allows you to create reports using a set of predefined templates to report on the various aspects of your virtual environment. Foglight for VMware includes a collection of predefined report templates.

You can generate, copy, and edit reports using the Reports tab on the VMware Environment dashboard, or alternatively the Reports dashboard included with the Management Server.

Figure 58. Reports tab

For complete information about this tab, see the Managing Capacity in Virtual Environments User Guide. For more information about the Reports dashboard, see the Foglight User Help.

You can generate, copy, and edit reports using the Reports dashboard included with the Management Server. For more information, see the Foglight User Help.

VMware Performance Agent configuration

The VMware Performance Agent collects data from the virtual infrastructure and sends it to the <Product Name>™ Management Server. The agent keeps track of resource utilization metrics and alerts you when certain pre-defined thresholds are reached.

VMware Performance Agent and Agent Manager configuration

On 64-bit hosts meeting the minimum system requirements, the embedded Agent Manager can be used to run VMware Performance Agents to monitor up to 500 virtual machines. If the total number of virtual machines to be monitored from a single agent host is greater than 500, an Agent Manager should be installed on a separate host.

If additional cartridges and agents are added to the environment, product performance should be monitored and agents moved off of the embedded Agent Manager to reduce the load.

Monitoring more than 4000 virtual machines from a single agent host

The Agent Manager JVM usually requires additional memory to monitor more than 4000 virtual machines. The total number of virtual machines is the total from all vCenters that will be monitored from all VMware Performance agents running on the Agent Manager.

The following calculations are guidelines, not hard and fast rules. Memory requirements can vary greatly from installation to installation with similar VM counts. If insufficient memory is configured, the failure mode is easily recognizable: all agents on the Agent Manager host will go into a broken state after the agent(s) were activated for a short period of time, usually within 24 hours. In addition, the Agent Manager log will contain a line similar to the following:

If this is the case, add memory greater than what is shown in the calculations below, in increments of 512 MB until the agents stabilize.

JVM memory requirements for VMware Performance agents are calculated using the following formula:

According to the above formula, monitoring 4000 virtual machines requires 2560 MB of memory:

This is the default setting for agents deployed on 64-bit systems.

Similarly, monitoring 8000 virtual machines requires 4608 MB of memory:

This requires a change in the default Agent Manager settings.

1
Determine the amount of additional memory required. This will be the total from the last step above minus the default value of 2560 MB. In the example above, this is 4608 MB – 2560 MB = 2048 MB.
2
On the agent machine, open the baseline.jvmargs.config file for editing. The file is located in the <Agent_Manager_home>/state/default/config directory.

Add the following lines to the memory settings section:
