<div>Hello,</div><div> </div><div>The two files which I shared were created by cron.

Please,<br />remove these files and let your crond create them, and then read their<br />contents and see if are correct.<br /><br />Besides this, I see some errors in your log file that makes me think<br />that your configuration file is either outdated or you removed a lot of<br />lines from it, which is not recommended.<br /><br />Please, read the FAQ <<a href="https://www.monitorix.org/faq.html#Q107" rel="noopener noreferrer">https://www.monitorix.org/faq.html#Q107</a>> to know<br />how to configure Monitorix properly.<br /><br />Regards.<br /><br /><br /><br />On 8/14/25 10:30, wilson rodrigues wrote:</p><blockquote> Hello,<br /> I misunderstood the purpose of running in parallel two cron jobs.

Hence you can have multiple cron jobs running at the<br /> same time. This suggestion didn't have any relationship with the errors<br /> in your log file.<br /> <br /> What are the contents of the files '/tmp/ping1_results.txt' and<br /> '/tmp/ping2_results.txt'?<br /> <br /> Also, please, paste you Monitorix log file.<br /> <br /> Regards.<br /> <br /> <br /> On 8/14/25 09:46, wilson rodrigues wrote:<br /> <br /> Hello,<br /> I have now separated two commands in two shell scripts and<br /> having error<br /> repeating twice in log.
