Abstract: The disclosed embodiments provide a system that processes data received from a remote system. During operation, the system sends, from a computer system to a remote system, a request for a local time at the remote system and records a time of transmission of the request. Next, the system obtains, from the remote system, a response to the request, wherein the response includes the local time of the remote system. The system then computes a difference between the time of transmission and the local time of the remote system to determine a time offset that accounts for a time difference between the computer system and the remote system. Finally, the system uses the time offset to standardize timestamps in time-series data received from the remote system, wherein standardizing the timestamps associated with the time-series data comprises adjusting the timestamps to conform to a time standard.

Abstract: Techniques and mechanisms are disclosed that enable a data collection system to adaptively control collection of data from one or more external data sources. At a high level, adaptively controlling collection of data from external data sources may include collecting performance information related to one or more data collection nodes and, in response to analyzing the collected performance information, adapting rates at which the data collection nodes send data collection requests to external data sources. Data collection performance information generally may include, but is not limited to, network traffic data, error messages generated by external data sources and/or data collection nodes, computing device performance information, and any other types of information related to a data collection node's ability to collect data from external data sources.
