Help for 1 Minute Polling

I followed this tutorial:

https://docs.librenms.org/Support/1-Minute-Polling/

First I updated the values: / settings / poller / rrdtool /

I converted the RRD files so that they can take the new configuration

But, which value to update in the “cron.d” concerning poller-wrapper.py ?

Thanks

From the link you posted https://docs.librenms.org/Support/1-Minute-Polling/ it seems your value in cron should correlate to the value of the rrdstep you set up in the web ui.

You must also change your cron entry for poller-wrapper.py for this to work
(if you change from the default 300 seconds).

Hi,

Ok, Im agree with you but, in the cron entry " */5 * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16", which is the value i need to change ?

* * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16

Thanks !

I will try this night.

*/1 * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16
if your rrdstep is 60 seconds.

What is the difference between "* * * * * " and “*/1 * * * *”?

nothing they are the same https://crontab.guru/
