The NAS Bridge dashboard displays pre-configured graphs showing system metrics.
About this task
- Cache Usage
- Intent Log Size
- Disk Rate
- Network Rate
- CPU Load
- Memory
- Object Store Latency
The standard NAS Bridge dashboard is read-only and cannot be modified.
Summaries of the graphs are provided in the following table. The default time frame specified in the graphs is "Today so far."
| Graph | Description |
|---|---|
Cache Usage |
Shows cache usage for each cache device over the specified time frame. Use the Cache Device drop-down list to select which cache device is shown. The Cache Usage graph includes two lines, as follows:
|
Intent Log Size |
Shows the Intent Log Size for each file system over the specified time frame. The Intent Log Size represents the degree to which the files in the cache have been "cleaned" (that is, persisted to the StorageGRID system). A non-zero value means that there are still operations in the queue to commit "dirty" files that have not been persisted to the StorageGRID system. A zero value means that all objects in the cache have been persisted. Use the File System drop-down list to select which file system is shown. |
Disk Rate |
Shows the number of bytes of data that were read and written per second by each disk in the system over the specified time frame. |
Network Rate |
Shows the data rate between the network and the NAS Bridge over the specified time frame. Also includes tables showing the minimum, maximum, and average rates for received and transmitted data. |
CPU Load |
Shows the CPU load over the specified time frame. This chart includes three lines that show the average load for 1-minute, 5-minute, and 10-minute intervals. |
Memory |
Shows RAM usage for the NAS Bridge in gibibytes (GiB) over the specified time frame.
|
Object Store Latency |
The communication time from the NAS Bridge to its configured StorageGRID grid and back. If this value is higher than a few milliseconds or fluctuates significantly, check your network setup. |
Steps
- Review the information in the graphs.
To... Do this... Determine the value of the data at an exact moment in time Move the cursor over the graph. Increase the amount of time shown Click Zoom Out or press Ctrl+Z. Shift the time backward Click < or press the t key followed by the left arrow key. Shift the time forward Click > or press the t key followed by the right arrow key. Specify a different time range for the graph Click the clock icon 
and select or enter the range. The default setting is Today so far.Refresh the data Click the refresh icon 
. Set an auto-refresh rate Click the clock icon, select how frequently you want the data to be refreshed, and click Apply. The default refresh rate is one minute.
