Intune generates a lot of data. Most of it isn’t worth watching closely. The skill in day-two operations isn’t finding more things to monitor – it’s identifying the small set of signals that tell you something real, and ignoring the rest.
Most Intune environments start with too much monitoring. Every report gets bookmarked. Every blade gets checked weekly. After a few months of nothing actionable surfacing from most of them, the reviews get skipped and nothing gets monitored at all. The useful signals get buried in the noise of everything else, and real problems go undetected until they’ve been quietly present for weeks.
The goal is a short list of things you actually check, on a cadence that makes sense, where findings are actionable rather than informational.
Device compliance is the highest-value thing to watch regularly. The compliance dashboard shows which devices are compliant, non-compliant, not evaluated, or in a grace period. A healthy environment has a stable compliance rate – the number doesn’t need to be perfect, but it should be stable. A compliance rate that’s drifting downward over weeks is a signal worth investigating. A sudden spike in non-compliant devices usually indicates a policy change, a software update that conflicted with a compliance requirement, or an enrollment issue. The compliance trend matters more than the snapshot.
Non-compliance reasons are more important than the non-compliance count. Drilling into why devices are non-compliant tells you whether you have a real security gap or a policy design problem. Devices non-compliant because they’re missing a required OS build indicate a patch management issue. Devices non-compliant because a compliance rule requires something the device can’t satisfy – a setting that isn’t applicable to that OS version, a hardware requirement that specific devices don’t meet – indicate a policy design problem that needs fixing rather than a device that needs remediating. Those are completely different problems with completely different responses.
Non-compliance reasons tell you whether you have a security problem or a policy problem. One requires device remediation. The other requires policy correction. Treating them the same wastes time on the wrong fix.
Application deployment failures are the second thing worth watching regularly. The app deployment report shows install success, failure, and pending states per application. Persistent failures on specific applications indicate detection logic problems, packaging issues, or compatibility conflicts. A sudden increase in failures across multiple applications often indicates an Intune service issue, a network connectivity problem, or a device configuration change that broke the delivery mechanism. Applications that consistently show a high pending rate on specific device groups indicate those devices aren’t checking in reliably – which is a separate problem worth investigating.
Configuration profile errors are worth a periodic check but don’t need daily attention. The configuration profile report shows which profiles applied successfully, which had errors, and which returned not applicable. A small number of not applicable results is normal – it means settings in a profile don’t apply to some devices in scope. A profile with a high error rate on specific devices warrants investigation. Persistent errors that nobody has investigated in months are a sign the monitoring cadence needs to be tightened.
Entra ID sign-in logs and Conditional Access reporting surface access patterns and policy behavior. The CA report in Entra ID shows which policies are being evaluated, what the results are, and whether policies in report-only mode are producing expected behavior. Checking this after any CA policy change – even a minor one – before moving out of report-only mode is the minimum responsible practice. Checking it periodically in steady state catches unexpected behavior from changes elsewhere in the environment that you didn’t anticipate affecting CA evaluation.
Defender for Endpoint alert volume is worth watching at a high level – not to investigate every alert, but to detect trends. A sudden increase in alerts across the fleet after a software deployment or a policy change indicates something worth looking at. Sustained low alert volume with no spikes is the normal healthy state for a well-configured environment.
The right monitoring cadence is weekly for compliance and app deployment, monthly for configuration profiles and CA behavior, and quarterly for a full environment health review. More frequent than that for most environments produces diminishing returns.
Automation reduces the overhead of monitoring without reducing its value. Intune’s built-in alerts can notify on compliance threshold breaches, enrollment failures, and certificate expiry. Setting these up means you’re notified when something crosses a threshold rather than having to check manually. The alerts that matter are the ones tied to actionable thresholds – a compliance rate dropping below a defined percentage, an enrollment failure rate spiking above normal, a certificate approaching expiry. Alerts for everything produce the same noise problem as monitoring everything manually.
