[英]How to use Stackdriver Structured Logging in App Engine Flex Java environment
[英]Google App Engine. Stackdriver. Logging with Java
我想將日志發布到 Stackdriver 的“自定義日志”。 這些功能是測試版,因此可能沒有描述,如何在 App Engine 上使用 Java API 進行日志記錄。 無論如何我想描述我的問題:我使用這個 API 版本:
"com.google.apis:google-api-services-logging:v2beta1-rev10-1.21.0"
所以,首先我像這樣構建日志對象(我希望這是正確的):
public static Logging createAuthorizedClient() throws IOException {
// Create the credential
HttpTransport transport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleCredential credential = GoogleCredential.getApplicationDefault(transport, jsonFactory);
if (credential.createScopedRequired()) {
credential = credential.createScoped(LoggingScopes.all());
}
return new Logging.Builder(transport, jsonFactory, credential).setApplicationName(SharedConstants.APPLICATION_ID).build();
}
獲得 Logging 客戶端后,我嘗試將條目推送到日志:
LogEntry lEntry = new LogEntry();
lEntry.setTextPayload("I want to see this log!");
WriteLogEntriesRequest writeLogEntriesRequest = new WriteLogEntriesRequest();
writeLogEntriesRequest.setLogName("My Super log");
List<LogEntry> listEntries = new ArrayList<>();
listEntries.add(lEntry);
writeLogEntriesRequest.setEntries(listEntries);
Logging logging = LoggingManager.createAuthorizedClient();
Write write = logging.entries().write(writeLogEntriesRequest);
WriteLogEntriesResponse writeLogResponse = write.execute();
但我得到的是:
com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 OK
{
"code" : 400,
"errors" : [ {
"domain" : "global",
"message" : "Invalid resource id",
"reason" : "badRequest"
} ],
"message" : "Invalid resource id",
"status" : "INVALID_ARGUMENT"
}
=== 更新:工作解決方案 ===
感謝 mshamma。 這是完整的代碼,如何將數據發送到日志記錄:
public boolean send() {
WriteLogEntriesResponse response = null;
try {
final String now = getNowUtc();
final String insertId = "entry-at-" + now;
final Map<String, String> labels = ImmutableMap.of("project_id", SharedConstants.APPLICATION_ID, "name",
"projects/" + SharedConstants.APPLICATION_ID + "/logs/" + this.logName);
Logging service = createAuthorizedClient();
MonitoredResource ressource = new MonitoredResource();
ressource.setType("logging_log");
ressource.setLabels(labels);
LogEntry entry = new LogEntry().setInsertId(insertId).setResource(ressource).setTimestamp(now)
.setJsonPayload(this.entriesMap)
.setLogName("projects/" + SharedConstants.APPLICATION_ID + "/logs/" + this.logName)
.setSeverity(this.severity);
WriteLogEntriesRequest content = (new WriteLogEntriesRequest())
.setEntries(Collections.singletonList(entry));
response = service.entries().write(content).execute();
} catch (Exception e) {
}
return response != null;
}
private static String getNowUtc() {
SimpleDateFormat dateFormatUtc = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
dateFormatUtc.setTimeZone(TimeZone.getTimeZone("UTC"));
return dateFormatUtc.format(new Date());
}
此代碼適用於最新版本的日志記錄 api
因此 EntriesMap 是:
private Map<String, Object> entriesMap;
我在非托管 Python 環境中遇到了同樣的問題。 我的工作正常,我可以在您的代碼中看到至少兩個問題。
日志名稱需要遵循以下模式:“projects/<project-id>/logs/<log-id>”。 在此處查看該字段的文檔: https : //cloud.google.com/logging/docs/api/ref_v2beta1/rest/v2beta1/LogEntry#SCHEMA_REPRESENTATION
您應該向日志條目 (lEntry) 和寫入日志條目請求 (writeLogEntriesRequest) 添加資源描述符。 對於 GAE,資源類型字段應設置為“gae_app”,並且您必須向資源添加三個標簽來標識您的 GAE 部署:“project_id”、“module_id”和“version_id”。
我希望這將有助於解決您的問題!
