Host disk bars were showing virtual filesystems like tmpfs, /dev, /run,
/sys, and Docker overlay mounts. These clutter the UI and don't represent
meaningful disk usage.
Changed from `shouldIgnoreReadOnlyFilesystem` (read-only only) to the
full `fsfilters.ShouldSkipFilesystem` which also excludes:
- Virtual FS types: tmpfs, devtmpfs, sysfs, proc, cgroup, etc.
- Special mountpoints: /dev, /proc, /sys, /run, /var/lib/docker, /snap
- Network filesystems: fuse, nfs, cifs, etc.

Add 13 test cases for convertPBSSnapshots covering:
- Empty/nil input handling
- Basic snapshot field mapping
- Files as string array
- Files as object array with filename field
- Invalid file objects ignored gracefully
- Verification status as string ("ok" vs other)
- Verification status as object with state field
- Verification object without state field
- Multiple snapshots with unique IDs
- Empty namespace handling in ID generation
- Container (ct) backup type
Coverage: convertPBSSnapshots 0% -> 100%
- Test nil input returns nil
- Test empty slice returns nil
- Test single task with all fields populated
- Test task with error state (failed tasks)
- Test multiple tasks conversion
- Test nil time pointers preserved as nil
- Test zero time values converted to nil (defensive handling)
- Test all optional time fields (UpdatedAt, StartedAt, CompletedAt)
Improves monitoring package coverage for Docker Swarm task handling.
- sanitizeGuestAddressStrings: IPv6 loopback with CIDR (::1/128) edge case
(96.2% -> 100%)
- parseContainerConfigNetworks: parts without equals, mac/ips/ip6addr/ip6prefix
key variants, whitespace-only values, all-empty results (97.2% -> 100%)
- mergeNVMeTempsIntoDisks: NVMe disk with no legacy temps (continue branch),
more disks than temps (break branch) (97% -> 100%)
Go map iteration order is non-deterministic, causing flaky test failures.
This fix ensures "Composite" sensor is always preferred over "Sensor 1"
by checking them in separate loops rather than relying on iteration order.
- recordGuestSnapshot: nil handling, field setting, map initialization
- GetDiagnosticSnapshots: nil/empty handling, sorting verification
Both functions now at 100% coverage.
When tasks have identical NextRun and Priority, the Less function
falls back to comparing InstanceName alphabetically. Add test to
cover this edge case branch, improving Less coverage to 100%.
Tests for LXC container config parsing functions:
- sanitizeRootFSDevice: rootfs device extraction
- collectIPsFromInterface: recursive IP extraction from various types
- parseContainerRawIPs: JSON IP parsing
- parseContainerConfigNetworks: network interface parsing with MAC
normalization, CIDR stripping, sorting
- parseContainerMountMetadata: mount point metadata parsing
- extractContainerRootDeviceFromConfig: root device extraction
- mergeContainerNetworkInterface: interface merging by name/MAC
- convertContainerDiskInfo: Proxmox disk info conversion
- ensureContainerRootDiskEntry: root disk entry creation
91+ test cases covering edge cases, invalid data, and complex scenarios.
Coverage improved from 40.6% to 42.2%.
Tests for all 9 functions handling Docker host identification:
- uniqueNonEmptyStrings: dedupe with order preservation
- sanitizeDockerHostSuffix: string cleaning for IDs
- tokenHintFromRecord: redacted token hints
- dockerHostIDExists: ID existence check
- dockerHostSuffixCandidates: candidate suffix generation
- fallbackDockerHostID: hash-based ID generation
- findMatchingDockerHost: host matching by various criteria
- generateDockerHostIdentifier: unique ID generation with suffixes
- resolveDockerHostIdentifier: main resolver orchestration
86 test cases covering edge cases (nil, empty, whitespace), Unicode
handling, and complex matching scenarios.
Tests cover nil/empty inputs, basic field copying, time fields
(CreatedAt/UpdatedAt with nil and zero value handling), update status
conversion, endpoint ports, and labels cloning.
- Use public API AcknowledgeDockerHostCommand instead of private function
- Use strings.Contains instead of custom helper functions
- Add test case for empty hostID (skips validation, succeeds)
The error message referenced "Settings -> Docker -> Removed hosts" but
that UI path no longer exists. The correct path is now
"Settings -> Agents -> Removed Docker Hosts".

Add 56 test cases covering:
- isTransientError: 13 cases for context errors, retryable MonitorErrors,
and standard error types (nil, Canceled, DeadlineExceeded, Timeout, etc.)
- shouldTryPortlessFallback: 14 cases for connection error patterns that
trigger port fallback (refused, reset, no such host, timeout variants)
- shouldAttemptFallback: 13 cases for timeout/deadline/canceled patterns
used in storage polling fallback
- classifyDLQReason: 8 cases for dead letter queue reason classification
(max_retry_attempts vs permanent_failure)
- Edge cases: 3 cases for overlapping error patterns and partial matches
First test file for these error classification utilities used in retry
and fallback decision logic.
Add 97 test cases for four utility functions in monitor.go:
- stringValue (30 cases): Type-to-string conversion for various Go types
including string, int types, float types, json.Number, fmt.Stringer
- anyToInt64 (34 cases): Interface-to-int64 conversion with overflow
handling, string parsing, and json.Number support
- parseInterfaceStat (15 cases): Interface stat map parsing for network
interface statistics
- extractGuestOSInfo (18 cases): QEMU guest agent OS info extraction
with fallback logic for various Linux distros, Windows, FreeBSD
Coverage for these functions: 0% → 100%
Package coverage: 37.5% → 38.5%
Added comprehensive tests for 6 previously untested pure utility functions:
- sortContent: sorts comma-separated storage content values
- formatSeconds: converts total seconds to HH:MM:SS format
- dedupeStringsPreserveOrder: deduplicates strings while preserving order
- sanitizeGuestAddressStrings: validates and filters IP addresses
- copyFloatPointer: creates independent copy of float64 pointer
- clampInterval: clamps time.Duration to specified bounds
Tests cover edge cases including empty inputs, boundary conditions,
special values (DHCP, loopback addresses), and various separators.
Coverage increased from 36.8% to 37.5%.
32 test cases covering makeNodeSnapshotKey and makeGuestSnapshotKey
utility functions used for diagnostic memory snapshot storage. Tests
cover simple inputs, edge cases (empty strings, negative VMIDs),
special characters, and key uniqueness verification. Also includes
struct field tests for NodeMemoryRaw and VMMemoryRaw.
First test file for diagnostic_snapshots.go. Coverage 36.7% → 36.8%.
The backup status indicator feature was incomplete - it added the UI
component but never populated VM/Container LastBackup from actual
backup data. Now SyncGuestBackupTimes() is called after storage
backups and PBS backups are polled, matching each guest's VMID to
its most recent backup timestamp.
Fixes#786
