Blower: The light blue line indicates that the blower (draws air to the sampler) was
running and no line means that the blower was off. No action has to be taken on the
Dev LAN regarding the blower states.
Detector: Missing intervals or gaps show that no data has been received for a specific
station or the automatic processing has failed. Known possible reasons are:
(a) The SHI message subsystem is down:
• Check the SHI message subsystem (see [IDC/DEVLAN/OG-SHI], section
3.4.8).
(b) PHD message did not successfully pass the processing pipeline:
Check the content of messages directory
to verify that RN
data messages from the station are received and stored on the Development LAN. Also IDCX.msgdisc table content may provide additional
information in this regard. If there are messages in status RUNNING and
there is an increasing number of messages in status RECEIVED a messageprocessing queue is blocked. This typically occurs after a crash of an
application, which unsuccessfully tried to process a message and left it in
status RUNNING. Update the message status from RUNNING to RECEIVED
in order to re-process the message, or to FAILED in order to avoid reprocessing.
/dvl/data/shared/messages/<yyyy>/<jjj>
Check the invalidmail directory
/dvl/data/shared/messages/invalidmail to verify that the
sender is successfully authenticated and RN data messages are not rejected.
Check the log files of the input pipeline processing chain in
/dvl/logs/rn/pipeline for any processing errors starting with the
file input_<yyyymmdd>.log where yyyymmdd corresponds to the date
of interest.
Check the log files of the automated analysis in /dvl/logs/rn/analyze
for the particulate samples and in /dvl/logs/rn/xanalyze for the
noble gas samples to identify any processing errors.
(c) Data are not being forwarded from the Operations LAN to the Development
LAN:
Check the recent procmail logs in /ops/logs/rn/procmail to determine if RN
data messages are forwarded to the Development LAN.
Check the invalidmail directory in /ops/logs/rn/procmail/INVALIDMAIL
to determine if procmail rejects any forwarded RN data messages.
Contact a processing engineer responsible for the IDC Operations LAN to
determine if RN data messages are sent to the Development LAN.
Contact the system administrator to determine if there are any general
email problems in the system.
