# Linux Operations Healthcheck Toolkit
|
||
|
|
|
||
|
|
This directory contains first-pass Linux diagnostics for common host checks. The scripts focus on health visibility, disk usage, service status, network troubleshooting, and lightweight reporting without making system changes.

## Scripts
|
||
|
|
|
||
|
|
- `healthcheck.sh` - consolidated host overview.
|
||
|
|
- `disk_check.sh` - threshold-based filesystem usage check.
|
||
|
|
- `service_check.sh` - service state validation for critical daemons.
|
||
|
|
- `system_report.sh` - timestamped report generation for quick evidence capture.
|
||
|
|
- `network_troubleshoot.sh` - local network, DNS, route, and connectivity checks.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd infra-run/scripts/bash/os-healthcheck
|
||
|
|
|
||
|
|
./healthcheck.sh
|
||
|
|
./disk_check.sh 90
|
||
|
|
./service_check.sh sshd nginx
|
||
|
|
./system_report.sh
|
||
|
|
./network_troubleshoot.sh 8.8.8.8
|
||
|
|
```
|
||

## Notes
|
||
|
|
|
||
|
|
- The toolkit is read-only and suited to initial triage.
|
||
|
|
- It aligns with the portfolio pattern of quick pre-check and evidence collection steps.
