Re: [Monitorix-general] [SPAM] want to monitor ping with monitorix

[Jordi S. <jo...@fi...>]

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.
