- NAB Data Corpus
- ---
-
- Data are ordered, timestamped, single-valued metrics. All data files contain anomalies, unless otherwise noted.
-
-
- ### Real data
- - realAWSCloudwatch/
-
- AWS server metrics as collected by the AmazonCloudwatch service. Example metrics include CPU Utilization, Network Bytes In, and Disk Read Bytes.
-
- - realAdExchange/
-
- Online advertisement clicking rates, where the metrics are cost-per-click (CPC) and cost per thousand impressions (CPM). One of the files is normal, without anomalies.
-
- - realKnownCause/
-
- This is data for which we know the anomaly causes; no hand labeling.
-
- - ambient_temperature_system_failure.csv: The ambient temperature in an office
- setting.
- - cpu_utilization_asg_misconfiguration.csv: From Amazon Web Services (AWS)
- monitoring CPU usage – i.e. average CPU usage across a given cluster. When
- usage is high, AWS spins up a new machine, and uses fewer machines when usage
- is low.
- - ec2_request_latency_system_failure.csv: CPU usage data from a server in
- Amazon's East Coast datacenter. The dataset ends with complete system failure
- resulting from a documented failure of AWS API servers. There's an interesting
- story behind this data in the [Numenta
- blog](http://numenta.com/blog/anomaly-of-the-week.html).
- - machine_temperature_system_failure.csv: Temperature sensor data of an
- internal component of a large, industrial mahcine. The first anomaly is a
- planned shutdown of the machine. The second anomaly is difficult to detect and
- directly led to the third anomaly, a catastrophic failure of the machine.
- - nyc_taxi.csv: Number of NYC taxi passengers, where the five anomalies occur
- during the NYC marathon, Thanksgiving, Christmas, New Years day, and a snow
- storm. The raw data is from the [NYC Taxi and Limousine Commission](http://www.nyc.gov/html/tlc/html/about/trip_record_data.shtml).
- The data file included here consists of aggregating the total number of
- taxi passengers into 30 minute buckets.
- - rogue_agent_key_hold.csv: Timing the key holds for several users of a
- computer, where the anomalies represent a change in the user.
- - rogue_agent_key_updown.csv: Timing the key strokes for several users of a
- computer, where the anomalies represent a change in the user.
-
- - realTraffic/
-
- Real time traffic data from the Twin Cities Metro area in Minnesota, collected
- by the
- [Minnesota Department of Transportation](http://www.dot.state.mn.us/tmc/trafficinfo/developers.html).
- Included metrics include occupancy, speed, and travel time from specific
- sensors.
-
- - realTweets/
-
- A collection of Twitter mentions of large publicly-traded companies
- such as Google and IBM. The metric value represents the number of mentions
- for a given ticker symbol every 5 minutes.
-
-
- ### Artificial data
-
- - artificialNoAnomaly/
-
- Artificially-generated data without any anomalies.
-
- - artificialWithAnomaly/
-
- Artificially-generated data with varying types of anomalies.
