Introduction

SA380 series loggers write a journal about the most important internal activities like startup, shutdown, communication.

The syslog is the first place to look during debugging and investigation.

Where to find the Syslog

SA380

GUI

Go to Menu. View Data. Select the appropriate date. Select the dateLog.txt file.

   

Syslog will show up as text file:

Web interface

 

You have to have network access to the logger to do this. It can be achieved by connecting directly with an Ethernet cable, or connecting remotely through a network.

You need to have the IP address of the logger!

 

Enter the logger's IP address into your web browser:

You will be prompted to enter username/password:

You will be able to browse the data stored on the logger as a folder:

Navigate to the syslog file:

                

The folder belonging an actual date can have multiple digital log files and a syslog file. Select the dateLog.txt syslog file:

 

SA380TX

GUI

Similarly to SA380: Go to Menu. Go to Digital instead of Real-time system log! Press Show. Select system log and press Show.

    

Syslog has to show up:

Web interface

For the SA380TX logger you have to enter the IP address and have to specify the port as well:

You will be prompted for username/password. This and navigating to the actual syslog is the same as on the SA380.

Notice that each syslog lines are broken into two lines on the screen to be able to view most of the parameters.

SA380TX-L

dPanel

This assumes you have connection to the SA380TX-L logger either connected with a USB cable or you have network access to the logger through GPRS alternatively there can be Ethernet card installed.

First you have to select the right type of connection:

For USB cable connection, select USB:

 dPanel have to pick up the logger connected to the computer. Press Connect.

The connected logger will enumerate the information on the Real-time tab:

To get to the syslog, select Historic:

 

Select Syslog on the sub-tab:

 Normally it shows the last syslog entries retrieved from the logger. First time around it will be empty.

To simply retrieve the latest syslog, press Refresh data:

Web interface

SA380TX-L loggers with new version of firmware (version number?) have web-based configuration tool. The presence of the web tool can be checked with dPanel:

 On the real-time tab we get a valid WWW version, which indicates the web-tool is installed on the logger.

Enter the logger's IP address into your browser:

The web configuration tool needs javascript enabled in your browser.

Successful connection will show the loading screen first:

Once loaded it shows the current configuration of the logger:

Navigate to the syslog: Select Historic tab. 

Historic data normally shows the syslog by default. If not, select Syslog sub-tab:

WebCFG retrieves the latest syslog entries:

 

How to read the Syslog

Basics

SyslogDescriptionExample
System startup                  First message after the logger boots.
System startup 1.5T444 29Oct14 serno=65532
System shutdown                 Usually the last message in the syslog before the logger powers down or restart. 
Daily status                    

Available disk space on each disks.

Slave unit statuses.

GPRS and dialup status.

Daily status dsk1:374M dsk2:Miss dsk3:Miss Master:Y Slaves:NNNNNNN RasDial:Disconnected RasServe:Enabled
Disk failed or not present      

Internal or External disk. Internal disk is critical.

SA380 needs external disk when used as juridical logger.

 
Remote access heartbeat receivedRemote client connected to the logger and retrieved site name and firmware version. 

Enabling RAS server             

Disabling RAS server            

Can be seen time-by-time in SA380 loggers to

make sure the RAS server is not hung up in call.

 

The SA380TX-L logger has a few more messages worth including here.

SyslogDescriptionExample
Database startedPart of the normal startup. Version indicates data structure changes.Database started Database File Manager version 0.2
Slave configuredSlave processor got configuration. Optional parameters show available digital and analogue channels.Slave configured AnaMask=0x0003, DigMask=0x0000000F
Slave has started loggingStarted the slave processor logging cycle. It is not logging during configuration phase. 

Errors

SyslogDescriptionExample
Thread stopped                  Software failure or possible overload. (1)thread=DiskLogger,state=8
Thread safety system restart    Software failure or possible overload. (2) 
Unexpected disk removal         Error: only for Internal 
Battery level low at startup    

Flat battery; battery is not charging. Let the logger charge the battery for a few hours.

If the error still shows, send the logger back to MPEC for battery replacement.

2.9V

Event receiver overflow         System is overloaded. (3) 
Could not delete folder         File system error? 
Could not create file           Important for SA380: must have external disk installed. 
Modem command failed            

Serial port error; modem error. It is not an error during modem baud-rate detection!

Try to restart communication on the logger.

missing echo
M Tx File processing failed     

Slow comms (file has been removed since), file system error.

Logger had no connection to the server long enough to fill the message queue in the meantime.

Check in the syslog if the GPRS communication was lost for a long time.

 

In case of system overload errors (1) (2) (3), it is a good idea to double-check the data collection settings. It is possible that the logger is collecting way too much data.

Acquire-on-change thresholds are the usual suspects. You may want to set the threshold higher.

GSM Modem

SA380TX

SyslogDescriptionExample
Modem power off                   
Modem power on

M Build Event                   

After 1.5 the logger only logs the fact that the message has been serialised.

tick:ticktime interval, smp:number of samples in message,evt=number of events

Events contain the samples.

On old loggers (before 1.5)
