station:

The LMA station identifier

name:

The LMA station name

status:

"up" indicates the LMA station is working. "down" indicates the LMA station has not reported its status recently, so is probably offline or off. The "sdate" and "stime" fields show the last time the station reported its status. "offline" indicates the system has no information on the last time the station reported its status.

sdate:

The Linux system date, from the BIOS clock.

stime:

The Linux system time, from the BIOS clock.

load:

The system load. x/y/z minute load average. x = 1 minute average, y = 5 minute average, z = 15 minute average. Unless doing something major, these numbers should all be much less than unity. (The one minute one might vary a bit, but for sure, you should generally see the 15 minute average be very close to zero, or else there may be a process consuming too much of the CPU.)

uptime:

The amount of time since the last reboot.

duty:

The percentage of time the station was taking data in the last 30 days

/:

The percent of full capacity for the / partition. (/ is where the core OS is located.) Should always be in the neighborhood of 80-90%. LMA data gets stored on separate partitions (see below).

/boot

The percent of full capacity for the /boot partition if there is one.

/dev/shm

The percent of full capacity for the /dev/shm filesystem.

/data:

The percent of full capacity for the /data partition. This is the primary data partition for the USB solid-state hard-disk.

PID:

This is the process ID for the lma_DataHandler program (the program which actually collects data from the LMA board, and writes it to shared memory). If there's a number there, then it is running. If there isn't a number, there is a problem. Note, no checking is done to ensure that only one process is running, so this isn't a perfect test, but if there's a number there, and the rest of the other things below are okay, we are golden.

PIDRD:

This is the process ID of the lma_ReadData program, the daemon which reads LMA data out of shared memory and writes it to a data file.

PIDTL:

This is the process ID of the lma_TrigLog program, the daemon which reads LMA status out of shared memory and writes it to a trigger file.

PIDAT:

This is the process ID of the lma_AutoThresh program, the daemon which adjusts the threshold.

PIDDEC:

This is the process ID of the lma_Decimate program, the daemon which reads LMA data out of shared memory, decimates it, and sends it to the real-time processing computer.

Phase:

The phase count of the oscillator -- the difference between 25,000,000 and the actual number of cycles for the local data clock.

pdate:

This is the date, as reported by LMA board.

ptime:

This is the time, as reported by the LMA board.

temp:

This is the temperature (Celsius) of the LMA board.

gps:

The number of satellites being tracked by the GPS receiver, as reported by the LMA board.

current trigfile:

The name of the current trigger log file, for a recent second. (Trigger logs are found in the directory /home/lma/log/.)

trig ID:

The station letter, as reported in the trigger log, for a recent second.

tdate:

The date, as reported in the trigger log file, for a recent second.

ttime:

The time, are reported in the trigger log file, for a recent second.

tver:

The firmware version for the LMA board, as reported in the trigger log file, for a recent second.

tthresh:

The threshold (in dBm) of the station, as reported in the trigger log file, for a recent second.

ttrigs/s:

The current trigger rate as reported by the trigger log file, for a recent second.

tsat:

The number of satellites being tracked by the GPS receiver, as reported in the trigger log file, for a recent second.

ttemp:

The temperature (Celsius) as reported in the trigger log file, for a recent second.

files today

This is the count of number of data files collected for the current day. There should be 6 ten-minute files per hour.

files today-1

This is the count of number of data files collected for yesterday. If all is well, this should be 144 (6 files per hour times 24 hours).

files today-2

This is the count of number of data files collected for two days ago. If all is well, this should be 144 (6 files per hour times 24 hours).

current datafile:

The data file which the lma_DataHandler program is current writing to (assuming it is currently active, otherwise it would be the one last written to). The data files are in the directory /home/lma/data/YYMMDD.

vp1

Voltage of solar panel 1

vp2

Voltage of solar panel 2

cp1

Current of solar panel 1

cp2

Current of solar panel 2

vb1

Voltage of battery 1

vb2

Voltage of battery 2

cb1

Current of battery 1

cb2

Current of battery 2

vl

Voltage to load

cl

Current to load

bytes/month

This shows the rolling total of bytes (upload + download) which the sensor has used on the network during the last 30 days.

decimation status

This indicates whether the decimation process has stopped working. (The decimation can stop working when the Internet dies -- the decimation program tries to send data to a no-longer-active Internet, which hangs the program.) If so, log onto the station and give the command "/root/bin/lma_restart.pl". There is a cron process which checks to make sure the decimation program is active, so this should be done automatically.
