/**
* DTO for pageable XLog request.
* - date : (required) date to retrieve as String format YYYYMMDD
* - serverId : serverId if available (mandatory if it's multi-server connected scouter webapp)
* - startTimeMillis : (required) start time as milliseconds(long)
* - endTimeMillis : (required) end time as milliseconds(long)
* - startHms : (required-exclusive with starTimeMillis) start time as hhmmss
* - endHms : (required-exclusive with endTimeMillis) end time as hhmmss
* - objHashes : (required) object hashes by comma separator also allowed with bracket. eg) 10011,10012 or [10011,10012]
* - pageCount : count to retrieve in one time. (max limit is 30,000, default 10,000)
* - lastTxid : available from previous response for paging support. (long)
* - lastXLogTime : available from previous response for paging support. (long)
