Example 1 with LogQuery

use of com.google.appengine.api.log.LogQuery in project teammates by TEAMMATES.

the class CompileLogsAction method getErrorLogs.

private List<AppLogLine> getErrorLogs() {
    LogService logService = LogServiceFactory.getLogService();
    long endTime = new Date().getTime();
    // Sets the range to 6 minutes to slightly overlap the 5 minute email timer
    long queryRange = 1000 * 60 * 6;
    long startTime = endTime - queryRange;
    LogQuery q = LogQuery.Builder.withDefaults().includeAppLogs(true).startTimeMillis(startTime).endTimeMillis(endTime).minLogLevel(LogLevel.ERROR);
    Iterable<RequestLogs> logs = logService.fetch(q);
    List<AppLogLine> errorLogs = new ArrayList<>();
    for (RequestLogs requestLogs : logs) {
        List<AppLogLine> logList = requestLogs.getAppLogLines();
        for (AppLogLine currentLog : logList) {
            LogLevel logLevel = currentLog.getLogLevel();
            if (LogLevel.FATAL == logLevel || LogLevel.ERROR == logLevel) {
                errorLogs.add(currentLog);
            }
