System Overview Table
This page shows you various tables generated from the current stats from all the systems, allowing you to quickly compare systems and check their health.
The Stats shown here cover approximately 4 hours, if a system doesn't have the stats, the backend process wasn't able to gather the data for over an hour. Any "blank" stat in the "System Overview Table" indicates that the data was not collected for that specific stat. One thing to note is that the Security Failures, Application and System Logs for any Microsoft® Windows 2003 and before OS are not collected due to performance issues.
Clicking on a servername in any of the tables will open a detailed page for that system's current stats, also any table header in the "System Overview Table" can be clicked, which will sort the table by that value (click again to reverse the sort order).
If you hover over the images in the "System Overview Table", the "tooltip" will show you the exact stats for the image.
Note that the "Stopped Services" column refers to Services that are set to start Automatically, but are currently not running.
This table shows the systems with a high Average CPU % Usage stat. This stat is collected over the last 3-4 hours.
This table shows the % Memory Used during the last time the stats were collected (normally within 15 minutes).
% Used - Calculated using the total system memory and the Windows Available Memory Stat
Avail - This is taken from the \Memory\Available Bytes perflong counter
Used - This is taken from the \Process(_Total)\Working Set perflong counter
Kernel - This is taken from the \Memory\Pool Nonpaged Bytes perflong counter
\Memory\Pool Nonpaged Bytes
Cache - This is taken from the \Memory\Cache Bytes perflong counter
Note: In theory, adding up the Windows Avail, Used, Kernel and Cache memory should add up to the system's physical memory, but in practice this does not work. This is the result of processes using shared DLLs and some RAM allocations that are not counted anywhere (such as trimmed working set pages that have yet to be written to disk). Refer to the "Top Hidden Memory" Table to see which systems are affected by this phenomenon.
This table shows the difference in Memory Stats when taking the total System Memory and subtracting the \Memory\Available Bytes, \Process(_Total)\Working Set, \Memory\Pool Nonpaged Bytes, \Memory\Cache Bytes counters.
On normal systems, this counter should be close to 0 or even in the negative numbers. There are some processes and applications that could affect this number tremendously and can be identified by using a tool such as SysInternals RamMap. Some identifiers that affect this are:
AWE - This usually refers to a SQL Server process running under "AWE" on systems that allow "Lock Pages in Memory". Note that this is the default when using Microsoft SQL Enterprise versions when the process runs under the Default account (simply run the process under a service account to disable this feature).
Driver Locked - This indicates a driver locked some memory. The most common culprits are Virtualization products. When running a VM, it uses "Driver Locked" memory to provide memory for the VM. Also, if a physical host is short on memory, it might "balloon" the Driver Locked memory on the Virtual Machine to free up memory so the host is not affected by over-committed memory settings.
Note that this info is produced from the latest collected data (usually collected every 15 minutes). For more information on this counter refer to the AppAdminTools Website.
This table shows the systems with the highest \Memory\Available Bytes perfmon stat. Showing the Top Stat allows you to make necessary resource adjustments in Virtual envionments. This info is produced from the latest collected data (usually collected every 15 minutes).
This table shows the logical drives with the highest Disk Used percentage. This allows you to identify which systems might become affected by an out of space disk issue. This info is produced from the latest collected data (usually collected every 15 minutes).
This table shows the logical drives with the highest Disk Free Space. Showing the Highest Free Space allows you to make necessary resource adjustments with Systems utilizing NAS or SAN storage or Systems in Virtual envionments. This info is produced from the latest collected data (usually collected every 15 minutes).
