Bandwidth Usage Reports

Lists each server and virtual guest on an account, and their bandwidth usage throughout the given time period.

Data Time Alignment

The SoftLayer_Metric_TrackingObject class will auto-align your requested time to its nearest data collection boundary.

For example, if you wanted bandwidth data from 2019-02-03T00:30:00 to 2019-02-04T00:30:01 with a 3600s rollup, you would get data back from 2019-02-03T01:00:00 to 2019-02-04T00:00:00

This is especially problematic when requesting rollups for 12 and 24 hour periods. For these, the collection boundary starts at 00:00 UTC. So if you are in CST timezone for example, your request of data from 2019-02-03T00:00:00 to 2019-02-04T00:00:00 will get aligned to 2019-02-03T18:00:00-06:00 and 2019-02-03T18:00:00-06:00

So if you are interested in daily values of your bandwidth, make sure to understand you should send in your requests in UTC so everything aligns to what you requested. This script does this for you, which should hopefully help.

NOTE Bandwidth from the Metric_TrackingObject is going to be in octets, or bytes.

 Softlayer Stores in octets (bytes), sizes printed are in Giga Bytes (octets / 1024^3)
Sum values are a running total for the time period requested.

Summary Reports

Possible values for Metric_Data_Type. All summaryTypes must be the same for each request.

KeyName

  • PUBLICIN
  • PUBLICOUT
  • PRIVATEIN
  • PRIVATEOUT

summaryType
