To eliminate ambiguity and help you make sense of your systems, the following units may be associated with metrics submitted to Datadog:
| type | unit(s) |
|---|---|
| BYTES | bit / byte / kibibyte / mebibyte / gibibyte / tebibyte / pebibyte / exbibyte |
| TIME | nanosecond / microsecond / millisecond / second / minute / hour / day / week |
| PERCENTAGE | percent_nano / percent / apdex / fraction |
| NETWORK | connection / request / packet / segment / response / message / payload / timeout / datagram / route / session |
| SYSTEM | process / thread / host / node / fault / service / instance / cpu |
| DISK | file / inode / sector / block |
| GENERAL | buffer / 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 |
| DB | table / index / lock / transaction / query / row / key / command / offset / record / object / cursor / assertion / scan / document / shard / flush / merge / refresh / fetch / column / commit / wait / ticket / question |
| CACHE | hit / miss / eviction / get / set |
| MONEY | dollar / cent |
| MEMORY | page / split |
| FREQUENCY | hertz / kilohertz / megahertz / gigahertz |
| LOGGING | entry |
| TEMPERATURE | degree celsius / degree fahrenheit |
| CPU | nanocore / 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.
