Memory performance data
The Overview page displays a graph of the aggregate performance data for the Memory used by the hosts selected in the filter. As described in View monitoring history, you can hover on a period point to view what CPU operation was taking place at that point in time. Each chart and associated performance metrics are described in the following table.
Chart |
Description |
|---|---|
Process Size |
The number of MB of total process memory for the MarkLogic process. |
RSS |
The total amount of GB of Process Resident Size (RSS) consumed by the cluster. |
Huge Pages |
The size of huge pages for the MarkLogic process in MB. Available on Linux platform. Sum of Sizes after /anon_hugepage in /proc/[MLpid]/smaps. |
Anon |
The total amount of GB of Process Anonymous Memory consumed by the cluster. |
Swap |
The swap rate (from Linux /proc/vmstat) for the cluster in pages/sec. |
File Memory |
The I/O page-in rate (from Linux /proc/vmstat) for the cluster in pages/sec. |
Forest Memory |
The amount of space forest data files take up in memory. |
Cache Memory |
The amount of virtual memory used by caches. |
Click on the arrow in the upper left-hand section of the MEMORY graph in the Overview page to view graphs that present more detailed MEMORY performance metrics. The charts on the MEMORY DETAIL page are described in the following table. The displayed metrics are drawn from /proc/vmstat.
