Overview
|
|
========
|
|
|
|
FoundationDB processes generate log files known as trace logs that include details about the sequence of events that a process performed and record a variety of metrics about that process. These log files are useful for observing the state of a cluster over time and for debugging issues that occur in the cluster, a client, or various tools.
|
|
|
|
Each file contains a sequence of events for a single process, ordered by time. Clients that use the multi-version or multi-threaded client features will generate :ref:`multiple log files simultaneously <mvc-logging>`. Each entry in the log file will be either an XML event or a JSON object that containts several mandatory fields and zero or more arbitrary fields. For example, the following is an event generated in the XML format::
|
|
|
|
<Event Severity="10" Time="1579736072.656689" Type="Net2Starting" ID="0000000000000000" Machine="1.1.1.1:4000" LogGroup="default"/>
|
|
|
|
Most FoundationDB processes generate trace logs in the format described in this document. This includes server and client processes, fdbcli, and backup and DR tooling.
