* Add gpu util, power and procs. Consolidated gpu calls into `data_harvester`. Changed config flag from `enable_gpu_memory` to `enable_gpu`. Added GPU utilization to the cpu widget. Added GPU process memory usage and utilization percentage to the proc widget. Added key binds for gpu process toggling. Added GPU power usage to the battery widget. Added bounds check to battery widget header. Show battery widget header when `gpu_enable`. Added feature flag `legacy-functions` to `nvml-wrapper`. updated config file(s). updated help text. updated docs. * Code Review: Remove GPU util from cpu widget Remove GPU power from battery widget Use reference for gpu widgets_to_harvest Extract match arm to function for feature gate * Code Review: add gmem% toggle * Do not poll gpu temp when filtered * Code Review Two Changes: adjust doc wordings remove extra references remove extra widget harvest checks init proc gpu values use convert_temp_unit for gpu temp

# Process Widget
|
|
|
|
The process widget displays a table containing information regarding a running process, along with sorting,
|
|
searching, and process control features.
|

</figure>
|
|
|
|
## Features
|
|
|
|
The process widget has three main components:
|
|
|
|
- The main process table
|
|
- The search sub-widget (opened with ++ctrl+f++ or ++slash++)
|
|
- The sort menu sub-widget (opened with ++s++ or ++f6++)
|
|
|
|
By default, the main process table displays the following information for each process:
|
|
|
|
- PID
|
|
- Name of the process
|
|
- CPU use percentage (note this is averaged out per available thread by default)
|
|
- Memory use percentage
|
|
- Reads per second
|
|
- Writes per second
|
|
- Total amount read
|
|
- Total amount written
|
|
- User
|
|
- Process state
|
|
|
|
It can also additionally display the following columns:
|
|
|
|
- Process running time
|
|
|
|
With the feature flag (`--enable_gpu` on Linux/Windows) and gpu process columns enabled in the configuration:
|
|
|
|
- GPU memory use percentage
|
|
- GPU core utilization percentage
|
|
|
|
|
|
See [the processes configuration page](../../configuration/config-file/processes.md) on how to customize which columns
|
|
are shown.
|
|
|
|
### Sorting
|
|
|
|
The table can be sorted by clicking on the table headers, which will either sort the table by that column, or if already
|
|
sorting by that column, reverse the sorting order.
|
|
|
|
Alternatively, one can sort using the sort menu sub-widget, which is brought up using ++s++ or ++f6++, and can be controlled by arrow keys or the mouse.
|
|
|
|

|
|
</figure>
|
|
|
|
### Grouping
|
|
|
|
Pressing ++tab++ in the table will group entries with the same name together. The PID column will be replaced with the number of entries in each group, and usage
|
|
is added together when displayed.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/process_grouped.webp" alt="A picture of grouped mode in a process widget."/>
|
|
</figure>
|
|
|
|
Note that the process state and user columns are disabled in this mode.
|
|
|
|
### Process termination
|
|
|
|
Pressing ++d+d++ or ++f9++ will allow you to terminate the currently selected process/process group. On Unix-like
|
|
operating systems, you are also able to control which specific signals to send (e.g. `SIGKILL`, `SIGTERM`).
|
|
|
|
<figure>
|
|

|
|
<figcaption><sub>The process termination menu on Linux</sub></figcaption>
|
|
</figure>
|
|
|
|
If you're on Windows, or if the `disable_advanced_kill` flag is set in the options or command-line, then a simpler termination
|
|
screen will be shown to confirm whether you want to kill that process/process group.
|

|
|
|
|
### Tree mode
|
|
|
|
Pressing ++t++ or ++f5++ in the table toggles tree mode in the process widget, displaying processes in regard to their parent-child process relationships.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/process_tree.webp" alt="A picture of tree mode in a process widget."/>
|
|
</figure>
|
|
|
|
A process in tree mode can also be "collapsed", hiding its children and any descendants, using either the ++minus++ or ++plus++ keys, or double-clicking on an entry.
|
|
|
|
Lastly, note that in tree mode, processes cannot be grouped together due to the behaviour of the two modes somewhat clashing.
|
|
|
|
### Full command
|
|
|
|
You can show the full command instead of just the process name by pressing ++P++.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/process_full.webp" alt="A picture of a process widget using full commands."/>
|
|
</figure>
|
|
|
|
### Search
|
|
|
|
Pressing ++slash++ or ++ctrl+f++ will open up the search sub-widget. By default, just typing in something will search by the process name.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/search/search.webp" alt="A picture of searching for a process with a simple search."/>
|
|
</figure>
|
|
|
|
This search can be further enhanced by matching by case, matching the entire word, or by regex.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/search/regex.webp" alt="A picture of searching for a process with a search condition that uses regex."/>
|
|
</figure>
|
|
|
|
We are able to also search for multiple things/conditions.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/search/or.webp" alt="A picture of searching for a process with a search condition that uses the or operator."/>
|
|
</figure>
|
|
|
|
And if our search uses a keyword, we need to use quotation marks around the term to properly search it.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/search/quotes.webp" alt="A picture of searching for a process with a search condition that needs quotation marks."/>
|
|
</figure>
|
|
|
|
Lastly, we can refine our search even further based on the other columns, like PID, CPU usage, etc., as well as grouping together conditions.
|
|
|
|
<figure>
|
|
<img src="../../../assets/screenshots/process/search/cpu.webp" alt="A picture of searching for a process with a search condition that uses the CPU keyword."/>
|
|
</figure>
|
|
|
|
You can also paste search queries (e.g. ++shift+insert++, ++ctrl+shift+v++).
|
|
|
|
#### Keywords
|
|
|
|
Note all keywords are case-insensitive. To search for a process/command that collides with a keyword, surround the term with quotes (e.x. `"cpu"`).
|
