Health Checks

Health Checks

This page lists every check SPSWeather runs against each farm in scope, what it reports, and the ExclusionRules key that disables it (see Configuration → ExclusionRules).

SharePoint checks

Check	Reports	ExclusionRules key
SharePoint version	Build/version of each SharePoint server	(always)
Servers	The SharePoint servers of the farm	(always)
Upgrade status	Whether a configuration upgrade action is required	(always)
Health Analyzer	Failing Health Analyzer rules surfaced in Central Administration	HealthStatus
Trust farm API	HTTP status of the trusted-farm REST API	APIHttpStatus
Site collections	HTTP status of the monitored site collections	SPSiteHttpStatus
Failed timer jobs	Timer-job failures over a lookback window, with a failure-ratio threshold	FailedTimerJob
Solutions (WSP)	Farm solution deployment status	WSPStatus
Content databases	Status and size of each content database	(always)
User Profile audiences	Audience compilation status	(always)

Search checks

Check	Reports	ExclusionRules key
Crawl status	Last crawl status per content source	(always)
Crawl logs	Crawl log error/warning counts	(always)
Search topology	State of the search topology components	(always)

System / IIS checks

Check	Reports	ExclusionRules key
Distributed Cache	AppFabric / Distributed Cache instance status	(always)
IIS application pools	State of the IIS application pools	(always)
IIS worker processes	w3wp.exe resource usage	IISW3WPStatus
IIS site certificates	TLS certificate validity/expiry per IIS site	(always)
Last reboot	Last reboot time of each server	(always)
.NET version	Installed .NET Framework version	(always)
Application event errors	Recent errors in the Windows Application event log	EvtViewerStatus
Disk usage	Drive size and free space	(always)

SQL Server checks

SQL data is collected from a SharePoint server with dependency-free ADO.NET (System.Data.SqlClient — no SqlServer module needed). The SQL servers are discovered from Get-SPDatabase, so checks follow the farm's own databases. The service account needs VIEW SERVER STATE and read access to master/msdb. An unreachable instance produces a single red row instead of failing the run.

Check	Reports	ExclusionRules key
Instances	Edition/version/build, MAXDOP (advisory if ≠ 1), max server memory, TempDB file count vs CPUs	SQLInstanceStatus
Databases	State, recovery model, data/log size, last full backup age, compatibility level, AutoShrink/AutoClose	SQLDatabaseStatus
Disk volumes	Free space per volume hosting SQL files (sys.dm_os_volume_stats)	SQLDiskStatus
Availability	AlwaysOn AG replica sync health and recent failed SQL Agent jobs	SQLAvailabilityStatus

SQL alert thresholds are configurable in the environment config: SQLDiskFreeThresholdPercent (default 15) and SQLBackupMaxAgeDays (default 3). Database offline state, a missing/old full backup, low volume free space, an unhealthy AG replica, a failed backup job, or an unreachable instance raise an alert; best-practice deviations (MAXDOP, memory, TempDB, AutoShrink/AutoClose) are shown as orange advisories without raising the global alert.

How an ALERT is raised

Every check returns rows flagged as informational or not (an internal IsInfo flag). When any collected check contains at least one non-informational (failed) row, SPSWeather:

• tags the email subject with [ALERT] (otherwise [INFO]), and
• raises the email priority to High, and
• writes a Warning (event ID 2000) to the SPSWeather Event Log.

In the HTML report, failing rows use the tdfailed (red) style, below-threshold timer-job failures use tdwarning (orange), and healthy rows use tdsuccess (green).

Disabling checks

Add the corresponding key to ExclusionRules in your config to skip a check. Authorized values:

None, APIHttpStatus, SPSiteHttpStatus, EvtViewerStatus, IISW3WPStatus, HealthStatus, WSPStatus, FailedTimerJob, SQLInstanceStatus, SQLDatabaseStatus, SQLDiskStatus, SQLAvailabilityStatus.

Checks marked (always) above are not individually excludable.
