com.google.cloud.logging
A client for Cloud Logging - Real-time log management and analysis.
Here's a simple usage example for using google-cloud from Compute Engine/App Engine Flexible. This example shows how to write and list log entries. For the complete source code see WriteAndListLogEntries.java.
LoggingOptions options = LoggingOptions.getDefaultInstance();
try(Logging logging = options.getService()) {
LogEntry firstEntry = LogEntry.newBuilder(StringPayload.of("message"))
.setLogName("test-log")
.setResource(MonitoredResource.builder("global")
.addLabel("project_id", options.getProjectId())
.build())
.build();
logging.write(Collections.singleton(firstEntry));
Page<LogEntry> entries = logging.listLogEntries(
EntryListOption.filter("logName=projects/" + options.getProjectId() + "/logs/test-log"));
Iterator<LogEntry> entryIterator = entries.iterateAll();
while (entryIterator.hasNext()) {
System.out.println(entryIterator.next());
}
}
This second example shows how to use a java.util.logging.Logger to write log entries
to Cloud Logging. The snippet installs a Cloud Logging handler using
LoggingHandler.addHandler(Logger, LoggingHandler). Notice that this could also be done through
the logging.properties file, adding the following line:
com.google.cloud.examples.logging.snippets.AddLoggingHandler.handlers=com.google.cloud.logging.LoggingHandler
For the complete source code see AddLoggingHandler.java.
