# Understanding the figures on Performance graphs

Where Performance tile graphs and drilldowns in SquaredUp show very small numbers they will use *m* (milli) or *µ* (micro) where appropriate, and large numbers will get *k* (kilo) or *M* (mega) assigned.

Name | Symbol | Value | Description |
---|---|---|---|

milli | m | 0.001 | One milli is a thousandth of one |

micro | µ | 0.000001 | One micro is a millionth of one |

kilo | k | 1000 | A thousand |

mega | M | 1000000 | A million |

The *k* means thousands, and should not be mistaken for kb.

The *M* means millions, not MB.

## Units of measurement

SCOM only stores the number values, not the unit of measurement such as % or GB.

The metric name often includes the units of measurement, for example *Memory - Available MBytes* or *PercentBandwidthUsedTotal.*

## Performance tiles metric label

In v4.8 and above you can add *metric labels* to Performance graphs.

If one of the pre-configured metric labels of percent, bytes, megabytes or seconds is chosen then SquaredUp will convert very small or large values which would normally be displayed as m, µ, k or M into the selected (or upscaled) metric.

For more information see Performance Metric Labels.

Performance drilldowns cannot be configured like tiles, so will continue to use m, µ, k or M as described in this article.

## Large numbers on a graph

When bytes, megabytes or seconds are selected SquaredUp will 'scale up' the label to MB, GB, minutes or hours as appropriate. When using the preconfigured options SquaredUp will also convert very small or large values which would normally be displayed as m, µ, k or M into the selected (or upscaled) metric. See Understanding the figures on Performance graphs.

The Bar Top n graph below shows a figure of 1.71k:

This is actually 1709, as you can see when hovering over the figure. The metric name shows that this figure is returned in MB.

When the *metric label* is changed to *megabytes* SquaredUp shows 1.67GB:

This is 1709 divided by 1024 and rounded to two decimal places to convert MB into GB.

Clicking on the Bar Top n graph takes you to the drilldown page, and when the time period is changes to show the same aggregation then the 1.71k avg figure is shown. This is because Performance drilldowns cannot be configured like tiles, so will continue to use m, µ, k or M.

## Small numbers on a graph

The drilldown graph below is showing some very small percentages for the metric `PercentBandwidthUsedTotal`

:

The y-axis uses *m* to indicate milli. The max figure of 7.08m is actually 0.00708

The latest and average figures use *µ* to show the very small figures. 12.7µ is actually 0.0000124, which correlates with the latest point on the graph.
