The FMS Overview view is a starting point for performance analysis of the Foglight Management Server. It displays information about the database activity, data service performance, JVM performance, and server load in one unified view.
In federated environments, explore the diagnostics for each individual server: Federation Master, Federation Child, or a standalone Foglight Management Server. To do that, click Choose a Foglight Server and select a host from the list that appears.
This view provides more information on:
• |
Data load summary (Data Service, Inserts per 5 minutes views). In the Inserts per 5 min embedded view, num_rows_inserted_per5min shows the number of rows inserted every five minutes, while avg_insert_per5min shows one-hour average of num_rows_inserted_per5min. Spikes on the Data Service embedded view often indicate some kind of data processing lull such as a high amount of incoming data (seen as an increase in batchesProcessed), or insufficient resources to process incoming data decrease in batchesDiscarded). |
• |
Whether there is enough memory (JVM Memory Usage view). In this view, memory_usage shows the heap memory usage, totalMemory shows the amount of total heap memory, and freeMemory is the free heap memory. A sawtooth on the JVM memory graph is normal, but if the amount of memory freed by a garbage collect (such as the height of the sawtooth) is small, you may need more memory on your system. A large topology results in a high amount of incoming data and a decrease in free memory. The amount of free memory should never be zero. If it does reach zero this is an indication to adjust the server configuration. |
• |
Whether the load on the server is too high (Server Load Status view). Server load is mostly determined by the memory usage in the JVM old generation. If the server runs out of memory it will go into an “overloaded” state. A server can be in this state and have some memory available in the JVM new generation. If that is the case, the server discards incoming agent data but can continue to service browser interface requests to some degree. If the server remains to be overloaded, it likely needs to be re-configured to have more memory available, or less workload coming from the browser interface and/or the agents. |
Incoming data spikes (batchesProcessed increases), slow processing (batchesDiscarded increases) | ||
Too large topology, too much incoming data (freeMemory increases) | ||
The Agents view is designed to see what agents you are running, listed by type. By selecting agent types in the tree, a graph showing the number of agents as a function of time is plotted. This graph is handy for viewing changes to the agents, for example if a number of agents that you did not know about were added, or checking if old agents are properly removed.

Copy: This view shows the activity of the ParNew garbage collector, used to reclaim memory in the JVM new generation part of the heap. In most cases, there is no need to be concerned with the data on this view unless the numbers become unreasonable (one hour or higher). |
• |
ConcurrentMarkSweep: This view shows the activity of the ConcurrentMarkSweep garbage collector, used to reclaim memory in the JVM old generation part of the heap. In general, the values appearing on this view should stay low. An occasional spike does not indicate any problems (such as once a day). If spikes become frequent, the Foglight Management Server memory allocation may need to be adjusted (for example, by balancing the size of new and old generations). In some cases it might be required to increase the overall Foglight Management Server heap. |

This view highlights the data and metrics that are being processed in time or getting discarded.
The Service - Data & Message view shows details on data handling of the Foglight Management Server such as the number of skipped messages and the number of discarded metrics. The top-right embedded view shows the percentage of data that is dropped by the server over time, while the top-left embedded view shows the counts of total and skipped messages over time. A high percentage of dropped data can often indicate a server overload. The embedded view in the bottom right is useful for indicating how long data processing is expected to take. If that value grows over time, that is a good indication that the Foglight Management Server cannot keep up with the load from the agents.

Some Foglight dashboards have reports associated with them. This allows you to run a report based on the current dashboard. You can generate the report using the Reports menu in the top-right corner.
The Performance Overview dashboard and Management Server View are associated with the Management Server Performance Summary Report. Run this report by choosing Management Server Performance Summary Report from the Reports menu, and specifying the input parameters in the report wizard.
The Misbehaving Clients tab displays the disconnections per count for a selected FglAM instance.
The following metrics are displayed for each agent:
• |
CDT Node Count: The number of internal data nodes produced by the CDT. Typically, there is one node for each topology object and its metrics, and one global (root) node in the tree. |
• |
CDT Value Count: The number of metrics and/or observations produced by the CDT. |
• |
Max Stack Depth: The depth of the data tree structure submitted by each agent instance. When a topology object in the data submission refers to another topology object, that increases the depth by one. When the second object refers to a third, the depth is increased again. |
• |
Node Count: The number of nodes in the submission. It is a measure of how large the data submission is. |
• |
Pre-processing time: The Agent Manager makes two passes over the data submitted by an agent. This is the time spent on the first pass, when the Agent Manager fills in references, validates the submission, calculates missing timestamps, and performs other pre-processing tasks. |
• |
Processing time: The length of time it takes the Agent Manager to transfer the data submission to the CDT processing engine of the Management Server. |
