Here code that doesn't use at but sleep; it doesn't need external storage of data but runs continuously.
Wat i suggest is to log evrything in the beginning by echoing the variables to the logfile, mainly the Delay to see if you have to adjust the tolerance at another value.
I let you code the different logs you want to make (i can help u) but try first the functioning of the script. You can add lines for monitoring purpose by echoing commands or start the script with the -x parameter like bash -x simple.sh
Code:
#!/bin/bash
File1=simple.txt # The file to check
LogFile=simple.log # The log file
DelayMax=30 # Timeout delay
Tolerance=2
# BEGIN ##############################
while true
do
StampNow=$(date +%s)/60 # stamp in minutes
StampFile=$(date -r "$File1" +%s)/60
let Delay=$StampNow-$StampFile
if [ $Delay -gt $DelayMax ]
then
echo "$(date) : ERROR : Timeout" >> $LogFile
# etc.
exit 1
elif [ $StampFile -eq $StampOld ]
then
sleep $Tolerance minutes # Retry a bit later
else
StampOld=$StampFile
let NewDelay=$StampNow-$StampFile+15+$Tolerance # To synchronize with the updating
sleep $NewDelay minutes
fi
done
nothing more before 7:00 or 8:00 GMT
Code:
frans@localhost-$ sleep 8 hours

torrus_monitor
TORRUS_MONITOR(8) torrus TORRUS_MONITOR(8)NAME
monitor - Torrus Monitor.
SYNOPSIS
torrus monitor --tree=TREENAME [options...]
DESCRIPTION
This command starts the Monitor process for the tree TREENAME. By default it forks into a daemon, sets the log output file to
/var/log/torrus/monitor.TREENAME.log, performs one monitoring cycle, and sleeps until the next cycle is scheduled. In daemon mode the log
file can be reopened by sending it a SIGHUP signal.
OPTIONS --nodaemon
Prevents the process from becoming a daemon and sets the log to STDERR.
--runonce
Instructs the script to run once and exit. Implies --nodaemon.
--delay=N
Makes the daemon sleep for N minutes before starting the first cycle. This would happen on the daemon startup and also after each
configuration recompilation. For example, when monitor and collector start simultaneously, the collector needs some time to retrieve
the data being monitored.
--debug
Sets the log level to debug.
--verbose
Sets the debug level to info.
--help
Displays a help message.
FILES
/etc/torrus/conf/torrus-siteconfig.pl
Torrus site configuration script.
/var/log/torrus/monitor.TREENAME.log
Monitor's log for the tree TREENAME.
