What is aggregate time series data?
Time aggregation is the aggregation of all data points for a single resource over a specified period (the granularity). Data aggregations in Resource Time Series reports are of the time aggregation type. Typically, multiple aggregated data points are presented in a report for a given reporting period.
What does aggregate time mean?
Aggregate hours is a statistic that is gathered by the U.S. Department of Labor (DOL). Aggregate hours represents the sum of hours worked by all employed people, either full- or part-time, during the course of a year. Aggregate hours can also refer to the total hours worked by one sector or group of workers.
How are time series stored in a database?
This can be a stock price, a scientific observation, or the load of a server. While there exist several database implementations specialized on handling time series data, there is no common format in which time series are stored and queried, and in theory any database engine can be used to handle time series data.
How are time series data formatted in metricbeat?
To summarize, within a Metricbeat document, time series data and metadata are mixed, and you need specific knowledge about the document format to retrieve exactly what you need. In contrast, if you want to process, analyze, or visualize time series data, the data typically should be in a table-like format like this:
Do you use linear regression in time series?
You should definitely not consider linear regression as you have time series data which has auto-correlative structure. Your post suggests a simplistic approach (30 day rolling means) which is an attempt to characterize your series. An ARIMA model is an optimization of “how many data points to use” and “how to weight them” .
When to use a time series in monitoring?
In a server monitoring use case, there will always be one key-value pair to specify which host a time series belongs to, but the additional information that can be added can be anything, and can later be used to only request metrics about a specific set of hosts.
