Another terminal based graphical activity monitor, inspired by [gtop](https://github.com/aksakalli/gtop) and [vtop](https://github.com/MrRio/vtop), this time written in [Go](https://golang.org/)!
See the [mini-blog](/xxxserxxx/gotop/wiki/Micro-Blog) for updates on the build status, and the [change log](/xxxserxxx/gotop/blob/master/CHANGELOG.md) for release updates.
Working and tested on Linux, FreeBSD and MacOS. Windows binaries are provided, but have limited testing. OpenBSD works with some caveats; cross-compiling is difficult and binaries are not provided.
If you install gotop by hand, or you download or create new layouts or colorschemes, you will need to put the layout files where gotop can find them. To see the list of directories gotop looks for files, run `gotop -h`. The first directory is always the directory from which gotop is run.
- **Prebuilt binaries**: Binaries for most systems can be downloaded from [the github releases page](https://github.com/xxxserxxx/gotop/releases). RPM and DEB packages are also provided.
- **Source**: This requires Go >= 1.14. `go get -u github.com/xxxserxxx/gotop/cmd/gotop`
gotop requires a font that has braille and block character Unicode code points; some distributions do not provide this. In the gotop repository is a `pcf` font that has these points, and setting this font may improve how gotop renders in your console. To use this, run these commands:
If Go is not installed or is the wrong version, and you don't have root access or don't want to upgrade Go, a script is provided to download Go and the gotop sources, compile gotop, and then clean up. See `scripts/install_without_root.sh`.
Run with `-h` to get an extensive list of command line arguments. Many of these can be configured by creating a configuration file; see the next section for more information. Key bindings can be viewed while gotop is running by pressing the `?` key, or they can be printed out by using the `--list keys` command.
In addition to the key bindings, the mouse can be used to control the process list:
Most command-line settings can be persisted into a configuration file. The config file is named `gotop.conf` and can be located in several places. The first place gotop will look is in the current directory; after this, the locations depend on the OS and distribution. On Linux using XDG, for instance, the home location of `~/.config/gotop/gotop.conf` is the second location. The last location is a system-wide global location, such as `/etc/gotop/gotop.conf`. The `-h` help command will print out all of the locations, in order. Command-line options override values in any config files, and only the first config file found is loaded.
A configuration file can be created using the `--write-config` command-line argument. This will try to place the config file in the home config directory (the second location), but if it's unable to do so it'll write a file to the current directory.
Config file changes can be made by combining command-line arguments with `--write-config`. For example, to persist the `solarized` theme, call:
gotop ships with a few colorschemes which can be set with the `-c` flag followed by the name of one. You can find all the colorschemes in the [colorschemes folder](./colorschemes).
To make a custom colorscheme, check out the [template](./colorschemes/template.go) for instructions and then use [default.json](./colorschemes/default.json) as a starter. Then put the file at `~/.config/gotop/<name>.json` and load it with `gotop -c <name>`. Colorschemes PR's are welcome!
Some devices have quite a number of data points; on OSX, for instance, there are dozens of temperature readings. These can be filtered through a configuration file. There is no command-line argument for this filter.
The list will grow, but for now the only device that supports filtering is the temperature widget. The configuration entry is called `temperature`, and it contains an exact-match list of comma-separated values with no spaces. To see the list of valid values, run gotop with the `--list devices` command. Gotop will print out the type of device and the legal values. For example, on Linux:
```
$ gotop --list devices
Temperatures:
acpitz
nvme_composite
nvme_sensor1
nvme_sensor2
pch_cannonlake
coretemp_packageid0
coretemp_core0
coretemp_core1
coretemp_core2
coretemp_core3
ath10k_hwmon
```
You might then add the following line to the config file. First, find where gotop looks for config files:
```
$ gotop -h | tail -n 6
Colorschemes & layouts that are not built-in are searched for (in order) in:
- [VictoriaMetrics/metrics](https://github.com/VictoriaMetrics/metrics) Check this out! The API is clean, elegant, introduces many fewer indirect dependencies than the Prometheus client, and adds 50% less size to binaries.
**ca. 2020-01-25** The original author of gotop started a new tool in Rust, called [ytop](https://github.com/cjbassi/ytop), and deprecated his Go version. This repository is a fork of original gotop project with a new maintainer to keep the project alive and growing. An objective of the fork is to maintain a small, focused core while providing a path to extend functionality for less universal use cases; examples of this is sensor support for NVidia graphics cards, and for aggregating data from remote gotop instances.
