Metrics Units

To eliminate ambiguity and help you make sense of your systems, the following units may be associated with metrics submitted to Datadog:

typeunit(s)
BYTESbit / byte / kibibyte / mebibyte / gibibyte / tebibyte / pebibyte / exbibyte
TIMEnanosecond / microsecond / millisecond / second / minute / hour / day / week
PERCENTAGEpercent_nano / percent / apdex / fraction
NETWORKconnection / request / packet / segment / response / message / payload / timeout / datagram / route / session
SYSTEMprocess / thread / host / node / fault / service / instance / cpu
DISKfile / inode / sector / block
GENERALbuffer / error / read / write / occurrence / event / time / unit / operation / item / task / worker / resource / garbage collection / email / sample / stage / monitor / location / check / attempt / device / update / method / job / container / execution / throttle / invocation / user / success / build / prediction
DBtable / index / lock / transaction / query / row / key / command / offset / record / object / cursor / assertion / scan / document / shard / flush / merge / refresh / fetch / column / commit / wait / ticket / question
CACHEhit / miss / eviction / get / set
MONEYdollar / cent
MEMORYpage / split
FREQUENCYhertz / kilohertz / megahertz / gigahertz
LOGGINGentry
TEMPERATUREdegree celsius / degree fahrenheit
CPUnanocore / microcore / millicore / core / kilocore / megacore / gigacore / teracore / petacore / exacore

Units are displayed automatically on timeseries graphs, query value widgets, and toplists, as shown in the following screenshot of a Redis dashboard:

On timeseries graphs, move your cursor over any graph to see the relevant units. The raw data is automatically converted to readable display units (fractions of a second to ms, millions of bytes per second to MiB/s, etc.):

Units are also displayed at the bottom of timeboard graphs, and metric descriptions are available by selecting Metrics Info from the gear dropdown:

To change a metric unit, navigate to the metric summary page and select a metric. Click Edit under Metadata and select a unit, such as bit or byte from the dropdown menu.
