The Reporting screen displays graphs of system information for CPU, disk, memory, network, NFS, partition, target, UPS, ZFS, and system functions. The CPU report displays by default.
The settings opens the Reports Configuration configuration screen.
Reports Configuration settings specify how TrueNAS displays the graphs and the host name of the Graphite server.
|Report CPU usage in Percent||Reports CPU usage in percent instead of units of kernel time.|
|Graphite Separate Instances||Sends the plugin instance and type instance to Graphite as separate path components: host.cpu.0.cpu.idle. Disabling sends the plugin and plugin instance as one path component and type and type instance as another: host.cpu-0.cpu-idle.|
|Remote Graphite Server Hostname||Remote Graphite server host name or IP address.|
|Graph age in Months||Maximum time (in months) TrueNAS stores a graph. Allowed values are 1-60. Changing this value causes the Confirm RRD Destroy dialog to display. Changes do not take effect until TrueNAS destroys the existing reporting database.|
|Number of Graph Points||The number of points for each hourly, daily, weekly, monthly, or yearly graph. Allowed values are 1-4096. Changing this value displays the Confirm RRD Destroy dialog. Changes do not take effect until TrueNAS destroys the existing reporting database.|
|Reset to Defaults||Resets all entered values and settings back to defaults.|
|CPU||Displays the CPU Temperature, CPU Usage, and System Load graphs.|
|Disk||Displays graphs for each selected system disk and by report type.|
|Memory||Displays both the Physical memory utilization and Swap utilization graphs.|
|Network||Displays an Interface Traffic graph for each interface in the system.|
|NFS||Displays the NFS Stats (Operations) and NFS Stats (Bytes) graphs.|
|Partition||Displays graphs showing disk space allocations.|
|System||Displays both the Processes and Uptime graphs.|
|Target||Displays graphs only for systems with iSCSI ports configured and shows the bandwidth statistics for iSCSI ports.|
|UPS||Displays the graphs only if the system is configured for and uses a UPS.|
|ZFS||Displays the ARC Size, ARC Hit Ratio, ARC Requests demand_data, ARC Requests demand_metadata, ARC Requests prefetch_data, and ARC Requests prefetch_metadata graphs with the Arc and L2 gigabytes and hits (%), and the hits, misses and total number of requests.|
The following sections provide examples of each report graph.
CPU graphs show the amount of time spent by the CPU in various states such as executing user code, executing system code, and being idle. Graphs of short-, mid-, and long-term load are shown, along with CPU temperature graphs.
Disk graphs shows read and write statistics on I/O, percent busy, latency, operations per second, pending I/O requests, and disk temperature. Use the Select Disks dropdown list to select the disks and the Select Reports dropdown to select the report types to display.
|Select All||Displays all available graphs for any or all disks selected on the Disks dropdown list.|
|Disk Temperature||Displays the minimum, maximum and mean temperature reading for the disk selected.|
|Disk I/O||Displays the disk read and write I/O stats in bytes/s.|
Temperature monitoring for the disk is disabled if HDD Standby is enabled. Check the Storage > Disks Edit Disk* configuration form for any or all disks in the system if you do not see the temperature monitoring graph.
Network graph report received and transmitted traffic in megabytes per second for each configured interface.
NFS graphs show information about the number of calls for each procedure and whether the system is a server or client.
Partition graphs display free, used, and reserved space for each pool and dataset. However, the disk space used by an individual zvol is not displayed as it is a block device.
System graphs display the number of processes grouped by state, sleeping, running, stopped, zombies and blocked, and system uptime.
ZFS graphs show compressed physical ARC size, hit ratio, demand data, demand metadata, and prefetch data and metadata.
