# sysinfo

## Python based scripts for obtaining system information from Linux.

* Python2 and Python3 compatible
* Output in JSON format
* Simple scripts and extensible structure
* Parallel commands execution
* Output to stdout or file
* Output can be processed by jq
* Storing output from commands in the selected directory
* Reading the stored outputs of commands from the selected directory

## Command-line arguments
```
usage: sysinfo.py [-h] [--all] [--error] [--export-only] [--export-dir PATH] [--import-dir PATH]
                  [--info] [--list] [--output OUTPUT] [--pool POOL] [--verbose] [commands [commands ...]]

positional arguments:
  commands                    Commands

optional arguments:
  -h, --help                  Show this help message and exit
  --all, -a                   Execute all commands.
  --error, -e                 Show only error outputs from commands.
  --export-only               Export output from commands without processing.
  --export-dir PATH           Path to the directory for saving output from commands.
  --import-dir PATH           Path to the directory for reading the stored outputs of commands.
  --info, -i                  List all commands with command line arguments.
  --list, -l                  List all commands.
  --output OUTPUT, -o OUTPUT  Path to the output file.
  --pool POOL, -p POOL        Pool size for parallel execution of commands. (default value is 5)
  --verbose, -v               Add more info to output - options, commands, raw command result.
```
## Examples

### Standart JSON output
```
python2 sysinfo.py lscpu
```
```json
{
    "lscpu": {
        "output": {
            "architecture": "armv6l",
            "bogomips": "996.14",
            "byteOrder": "Little Endian",
            "coresPerSocket": "1",
            "cpuMaxMhz": "1000.0000",

            "threadsPerCore": "1",
            "vendorId": "ARM"
        }
    }
}
```

### Get single value
```
python2 sysinfo.py lscpu | jq -r ".lscpu.output.modelName"
```
```

```

### Output in CSV format
```
python2 sysinfo.py lsblk | jq -r ".lsblk.output[] | [.name, .label, .size,
.mountpoint] | @csv"
```

"mmcblk0p2","rootfs","14.3G","/"
```

### Storing output from commands in the selected directory
```
sudo python sysinfo.py --export-dir ./out blkid
```

### Reading the stored outputs of commands from the selected directory.
```
sudo python sysinfo.py --import-dir ./out blkid
