# config system

Commands for updating firmware, diagnosing system health, and making tweaks to basic system functions.

---

## show system status

Runs a health check on various aspects of the host machine, and reports back if it finds any potential problems, urgent or not.

```plaintext
show system status
```

Example output:

```plaintext
[Thu Dec 19 04:18:05 2024] > show system status

## show system autocomplete

FMADIO systems feature a small selection of Bash auto-complete scripts to make common operations easier (e.g. LXC start-up/shut-down, stream_cat). This command reports whether these scripts are automatically exported to newly-spawned Bash shells.

```plaintext
show system autocomplete
```

Example output:

```plaintext
[Thu Dec 19 04:23:02 2024] > show system autocomplete
[Thu Dec 19 04:23:02 2024] Bash auto-complete script self-export is enabled
```

This command supports JSON output when run from the shell:

```plaintext
fmadio@fmadio20v3-508:/mnt/store0/develop$ fmadiocli --json "show system autocomplete"
fmad fmadlua Dec 18 2024 (/opt/fmadio/bin/fmadiolua --nocal /opt/fmadio/bin/fmadiocli --json show system autocomplete )
Disable cycle calibration
[Thu Dec 19 04:24:38 2024] CmdLine [--json]
[Thu Dec 19 04:24:38 2024] JSON [show system autocomplete]
{"IsJSON":true,"Status":true,"System.AutoComplete":true}
```

---

## config system autocomplete

FMADIO systems feature a small selection of Bash auto-complete scripts to make common operations easier (e.g. LXC start-up/shut-down, stream_cat). This command changes whether these scripts are automatically exported to newly-spawned Bash shells.

```plaintext
config system autocomplete <true|false>
```

Example output:

```plaintext
[Thu Dec 19 04:31:47 2024] > config system autocomplete false
[Thu Dec 19 04:31:47 2024] disabled Bash auto-complete rule self-export on host startup
```

---

## show system firmware

Prints a list of all the firmware images currently uploaded to the system and reports on which image is presently installed.

```plaintext
show system firmware
```

Example output:

## config system firmware install

After uploading a firmware image, it is unpacked and ready for installation using this command. Its name can be given, in which case the file at `/mnt/system/firmware/&lt;name&gt;` will be installed. Alternatively, its absolute path can be given, in which case that path will be used as-is. **Note that the new installation will only take affect after rebooting the system.**

```plaintext
config system firmware install <firmware image name or path>
```

Example output:

## show system cpu

Prints a table of all logical cores on the system and their properties, including what role they have been assigned.

A CPU which is assigned to “fmadio” has affinity to the capture device itself, and if a CPU is described as “belonging to the system” (the right-most column in the table), that means that it is always forced to the “fmadio” assignment.

```

## config system cpu

Modify the CPU mapping configuration. `strict` makes it such that every CPU gives priority to the capture device; `relax` makes it such that the only CPUs which give priority to the capture device are those for which it is mandatory.

`reload` is meant for use after manually modifying `/opt/fmadio/etc/time.lua`; this reloading is done automatically if using `strict` or `relax`.

```plaintext
config system cpu <strict|relax|reload>
```

Example output:

```plaintext
[Tue Jan 21 04:31:50 2025] > config system cpu strict

**Note:** this command requires sudo permissions to function correctly.

**Note:** the system **must** be rebooted after this command is done in order for it to take effect.

## config system iopriority

Set how aggressively captured packets get written to disk. `strict` is the default. `balance` reduces contention with other processes, but introduces some risk that packets can be lost during periods of very high network traffic.

```plaintext
config system iopriority <strict|balance>
```

Example output:

```plaintext
[Sat Jan 18 01:07:09 2025] > config system iopriority strict
[Sat Jan 18 01:07:13 2025] Set capture IO priority to strict mode
[Sat Jan 18 01:07:17 2025] > config system iopriority balance
[Sat Jan 18 01:07:17 2025] Set capture IO priority to balance mode
```
