Netdata¶
Netdata provides real-time performance and health monitoring for your DiskStation with an interactive web dashboard.
Package Information¶
| Property | Value |
|---|---|
| Package Name | netdata |
| Upstream | github.com/netdata/netdata |
| License | GPLv3 |
Prerequisites¶
- DSM 7.0 or newer
- For per-process disk I/O monitoring: SSH access (see Post-Install)
Installation¶
Install netdata from Package Center. The web dashboard is available at http://your-nas:19999 and appears in the DSM main menu.
Post-Install¶
Enable Process Monitoring and System Logs (Optional)¶
Per-process disk I/O monitoring requires apps.plugin to run with elevated privileges, and browsing systemd journal logs requires the same for systemd-journal.plugin. DSM 7 blocks setuid binaries from unsigned packages, so this must be applied manually after install:
This prompts for your DSM password when needed, grants root privileges to both plugins, and restarts the package. It only needs to be run once per install or upgrade.
After running it, process monitoring appears under Metrics, and system journal logs are browsable under Logs in the web UI.
Verify It's Running¶
The dashboard at http://your-nas:19999 should load immediately.
Configuration¶

Troubleshooting¶
Disk I/O not showing per process¶
Run netdata-fix from SSH. It grants the needed root privileges and restarts the package for you.
System logs not appearing¶
Run netdata-fix from SSH. The systemd-journal.plugin needs root privileges (via setuid) to read the journal files, which DSM blocks for unsigned packages until the fix is applied.
