Better use a<br />crontab line for each command.<br /><br />I don't know that is 'fcron', I only have 'cronie' in my Fedora.<br /><br />Regarding the error in the log file, can you, please, paste here the<br />section <gensens> from your configuration file?<br /><br />Regards.<br /><br /><br /><br />On 8/14/25 08:30, wilson rodrigues wrote:</p><blockquote> I am using this command as per <a href="https://www.monitorix.org/faq.html" rel="noopener noreferrer">https://www.monitorix.org/faq.html</a><br /> <<a href="https://www.monitorix.org/faq.html" rel="noopener noreferrer">https://www.monitorix.org/faq.html</a>> (Is there an easy way to integrate<br /> a ping statistic?)<br /> <br /> |ping -c 5 -nq 8.8.8.8 | tail -1 | awk '{if ( $4 == "" ) { print<br /> "0/0/0/0" } else { print $4}}' | awk -F / '{print $2 }' > /tmp/<br /> ping1_results.txt ping -c 5 -nq 8.8.4.4 | tail -1 | awk '{if ( $4 ==<br /> "" ) { print "0/0/0/0" } else { print $4}}' | awk -F / '{print $2 }' > /<br /> tmp/ping2_results.txt |<br /> <br /> I have created a shell script with above commands.
