Read Your Android Fleet's Health at a Glance

To read your fleet’s health at a glance, you need one number per state, in words, with the rule behind it and a way to jump to the phones that make it up. Colour alone is not enough, and neither is a list you have to scroll.

Picture a Monday morning at a small cleaning company. Twelve phones went out with crews on Friday. Before the first job, the office manager wants to know one thing. Are all twelve fine, or is one of them going to be a problem today?

The old way is a spreadsheet, a few text messages and a guess. The better way is a chart that says “11 Healthy (92%), 1 Needs attention (8%)” and lets you click straight to the one phone.

Here is how that works, and how to read it without second-guessing the colours.

What “healthy” actually means

A health chart is only useful if you know the rules. Otherwise a green slice is just a green slice.

The NounDesk dashboard sorts every live phone into one of three groups. It checks the rules from top to bottom, and the first rule that matches wins, so each phone lands in exactly one group.

Critical if any of these is true:

• Google’s security check rates it potentially compromised.
• It is in lost mode.
• It has been offline for more than 24 hours and is not compliant.

Needs attention if any of these is true:

• It is not compliant with its security policy.
• Google’s security check rates it at risk.
• It has been offline for more than 24 hours.
• It is disabled or being erased.

Healthy is everything else. Compliant, no security warning, and seen in the last 24 hours.

The fleet health rules guide spells all of this out with examples. You can also open How these are calculated under the chart itself.

Only live phones count. Phones still waiting to enroll, erased phones and retired phones are left out, and the chart’s subtitle says how many phones it covers.

Why offline does not mean broken

A phone that drops off the network for an hour is not a problem. A technician in a basement, a driver in a dead zone, a phone that ran flat at lunch. If every gap turned the chart red, you would stop looking at it.

So NounDesk uses four connectivity states:

• Online: seen in the last 15 minutes.
• Recently offline: seen in the last 24 hours.
• Offline: not seen for more than 24 hours.
• Not seen yet: enrolled but never checked in.

A Recently offline phone can still be Healthy. Only a full day without a check-in moves a phone to Needs attention, and only offline plus not compliant makes it Critical.

Charts you can read without a legend

The dashboard shows fleet health as a donut chart. Every slice carries its label, its count and its percentage as text, right beside it. You never have to match a colour to a key.

That matters more than it sounds. Colour blindness is common, and red against amber is the classic pair that blurs. The amber in these charts is lighter so it stays distinct from red, but the text is what does the work. The chart reads the same in black and white.

Percentages are rounded so they always add up to 100%.

Click any slice’s label and you land on the matching phones. Healthy opens the compliant phones. Needs attention or Critical opens the phones that need you.

The same charts on the Reports page

The Reports page uses the same donut charts for four questions:

• Compliance: how many phones meet their policy.
• Connectivity: how many are online, recently offline, offline or not seen yet.
• Device Trust: how many are Trusted, At risk, Not trusted or not reported yet.
• Security update age: how old each phone’s last security update is.

Each works the same way. Label, count and percentage on every slice, and a click through to the phones.

Longer breakdowns stay as bar charts. Policy, group and Android version can have many entries, and a donut with eight thin slices is harder to read than a row of bars. The reports and audit log guide covers the full page, including the CSV downloads.

If your Monday check keeps turning up old security updates, our guide to keeping company Android phones updated has a short monthly routine.

How to read your fleet in NounDesk

Every role can see the dashboard and reports, including Viewers.

1. Open the Dashboard. Read the tiles across the top: total devices, online, offline, compliant, needs attention, security risks, open alerts and any devices waiting to enroll.
2. Look at the Fleet health chart. Read the count and percentage on each slice.
3. Select Needs attention or Critical to open the phones behind them.
4. Open a phone and read why it is there. A problem reads in words, for example a required app that is missing.
5. For the wider view, go to Reports and read the compliance, connectivity, Device Trust and security update age charts.

The honest limits

The tile and the chart count different things. The Needs attention tile counts compliance only. The Needs attention slice in the chart also counts offline, at-risk and disabled phones, and moves the most serious to Critical. If the two numbers differ, that is why.

It shows what phones last reported. A phone that is switched off still shows its last known state until it checks in again, or until a day passes and it moves to Needs attention.

It tells you. It does not fix. The chart points at the phone. Changing a policy, chasing an update or locking the phone is still your job.

Company-owned Android only. The charts cover phones and tablets enrolled in NounDesk, which means company-owned Android 8 or newer.

What to do this week

1. Pick a time for the check. Monday at 8 works for most crews. It takes a minute once it is a habit.
2. Open How these are calculated once. Read the three rules, so a slice never surprises you.
3. Clear every Critical phone the same day. Start with any phone flagged as potentially compromised.
4. Work through Needs attention by the end of the week. Most are a missing app, an old update or a phone left in a drawer.
5. Look at the security update age chart once a month. It is the one an insurance questionnaire tends to ask about.

FAQ

What does Needs attention mean on the fleet health chart?

It means the phone is not compliant, is flagged at risk by Google’s security check, has been offline for more than 24 hours, or is disabled. The full rules are under How these are calculated.

Can I read the charts if I am colour-blind?

Yes. Every slice shows its label, count and percentage as text, so you never rely on colour alone, and the amber is lighter so it stays distinct from red.

Why is a phone that was offline this morning still Healthy?

Because it was seen in the last 24 hours. Only a phone that has not checked in for a full day moves to Needs attention.

How do I get from a chart to the actual phones?

Click the slice’s label. It opens the devices list filtered to the phones in that slice.
