Perfect, then I have updated the example in the Monitorix web site.
Thank you.

Hello,
If the contents you shared were created by crond then problem might be
that at the time when Monitorix reads the files they are truncated,
since the crond takes some time to create them and Monitorix tries to
read both files around the sezond zero.
I'd recommend you to prefix the lines in your scripts with a 'sleep 10',
to make sure that Monitorix reads the previous values before the files
get truncated,
Let me know if that worked for you.
Regards.

Hello,
If running the scripts manually the graphs are created
successfully then
the problem is in your crond daemon, not in Monitorix.
Don't show me the contents of these two files after
executing the
scripts manually since we already know that it works this
way. Please,
remove these files and let your crond create them, and
then read their
contents and see if are correct.
Besides this, I see some errors in your log file that
makes me think
that your configuration file is either outdated or you
removed a lot of
lines from it, which is not recommended.

Hello,
The recommendation to use two commands is to
have them run
in parallel
instead of serial. Hence you can have multiple
cron jobs
running at the
same time. This suggestion didn't have any

in your log file.
What are the contents of the files '/tmp/

Hello,
If you use only a single script to
execute these two
commands you must
keep in mind that the second command
will be
executed 5
seconds later.
That won't scale well if you plan to
track more
pings.
Better use a
crontab line for each command.
I don't know that is 'fcron', I only have
'cronie' in my
Fedora.
Regarding the error in the log file,
can you,
please,
paste here the
section <gensens> from your
configuration file?
Regards.

I have created a shell script
with above
commands.
When the
script is
run manually it is working fine.
Getting
the two
graphs in
monitorix.
But when same script is run in
fcron only
ping2 graph is
displaying
correctly. My crontab entry is
* * * * * root sh /root/bin/
monitorix_ping_gensens.sh
Error in /var/log/monitorix is
Use of
uninitialized
value $val in
division (/) at /usr/lib64/
monitorix/
gensens.pm line
156.
What I have tried: Disabling
fcron entry
and running
script
manually
works fine. With fcron only
ping2 graph is
working.
Sincerely,
Wilson Rodrigues
