Diagnostics: Settings

Per cluster

Part of Diagnostics.

General

Enabled schedulation

Master on/off switch for the scheduled scan

• Default: off

Cron Schedule

When the scheduled scan runs

• Default: 0 6 * * *

Number which should will keep

Max number of past scan results to retain (minimum 1)

• Default: 30

Notifier

Notifier configurations that receive the report at the end of every scan (scheduled or manual). Nothing is sent when both attachment switches below are off

Attach PDF report

Attach the PDF report to the notification

• Default: on

Attach Excel report

Attach the Excel workbook to the notification

• Default: off

Profiles

The Fast, Standard and Full buttons at the top of the settings load a ready-made set of values (thresholds go back to their defaults):

Profile	What it does
Fast	Skips the slowest reads (backup content, snapshots, LVM-thin metadata) for a quick scan of large clusters
Standard	The defaults
Full	Turns on every optional check (S.M.A.R.T. details, ZFS pool details, NVD CVE lookup, OK results) for audits

API

Setting	Default	Purpose
Max parallel requests	5	Max parallel requests when fetching data (1 = sequential)
API timeout (seconds)	0	API timeout in seconds (0 = use the default)
Include OK results (audit mode)	off	Also emit a result for every check that passes (Gravity = Ok). Useful for audit-style reports proving controls were verified, not only violated

Threshold: Node / Qemu / Lxc

Each of the three contexts (Node, Qemu, Lxc) has its own RRD Data and Thresholds. Node has extra checks, listed below.

RRD Data	Default	Purpose
Time frame	Day	Period of the metrics analysed: Hour, Day (last 24 hours), Week (last 7 days), Month or Year
Consolidation	Average	Average = smoothed trend over the period, Maximum = peak detection, catches short spikes

Threshold	Warning	Critical
CPU (%)	70	85
Memory (%)	70	85
Network (%)	0	0
Health Score, Node	70	50
Health Score, Qemu / Lxc	60	40
PSI Pressure (PVE 9.0+): CPU (some) (%), Qemu / Lxc	50	80
PSI Pressure (PVE 9.0+): CPU (some) (%), Node	40	70
PSI Pressure (PVE 9.0+): I/O (full) (%), Qemu / Lxc	20	50
PSI Pressure (PVE 9.0+): I/O (full) (%), Node	10	30
PSI Pressure (PVE 9.0+): Memory (full) (%), Qemu / Lxc	10	30
PSI Pressure (PVE 9.0+): Memory (full) (%), Node	5	15

Node-only thresholds

Setting	Default	Purpose
Max vCPU Ratio	4.0	Warn when total vCPUs / physical CPUs exceeds this ratio
Consolidation CPU (%)	10	Below this, the node is considered underutilised
Consolidation Memory (%)	20	Below this, the node is considered underutilised
IOWait (%)	Warn 10 / Crit 25	Average CPU time spent waiting for I/O over the RRD time frame; sustained high values point to a storage bottleneck
S.M.A.R.T.	off	Per-disk SMART attribute scan (1 API call per disk per node)
S.M.A.R.T. → Temperature (°C)	Warn 55 / Crit 65	Disk temperature thresholds (set Warning to 0 to disable)
S.M.A.R.T. → SSD Wearout (%)	Warn 70 / Crit 85	Percentage of SSD life consumed before warning
ZFS detail checks	off	Deeper ZFS pool status check
LVM-thin metadata check	on	LVM-thin metadata usage check (full metadata pool causes data corruption)

Storage thresholds

Threshold	Warning	Critical
Usage (%)	70	85

Snapshot checks

Setting	Default	Purpose
Enable	on	Toggle the per-VM/CT snapshot scan (skip the API call when off)
Max Count	10	Warn when a VM/CT has more than this many snapshots (0 = disabled)
Max Age (days)	30	Warn when the oldest snapshot exceeds this age in days (0 = disabled)

Backup checks

Setting	Default	Purpose
Enable	on	Toggle backup hygiene checks (skip API calls when off)
Max Age (days)	60	Warn about backups older than this on storage (0 = disabled)
Recent Days	7	Warn when no backup exists within this window (RPO violation, 0 = disabled)

CVE checks

Setting	Default	Purpose
NVD checks for Proxmox VE specific CVE	off	Lookup NVD for Proxmox VE specific CVEs (CPE filter)
Min CVSS score	7.0	Report only CVEs at or above this score (0 = report all)
