Hello,

It’s very strange.
poller-wrapper.py is not work when use cron!!!
For example, when I start manualy for polling all switch with the name starting loop0-pn :

/poller.php -h loop0-pn* ---->>> It's ok , RRD Ok
When I configure Cron for this , it’s Ok

When use /poller-wrapper.py manualy it’s Ok
RRD file is updated.

But when I use poller-wrapper.py in cron, it’s not ok

For exemple, i configure cron for polling my device with poller-wrapper.py (all 15mn)

I can see, via rrdtool dump rrd/sw-23-strasbourg-1.reseau.nantes.net/ping-perf.rrd
The rrd file isn’t not updated.

Hi,

I think to have undertand,
It’s complicated to me to explained to you…

In my cron, i launch poller-wrapper.py all 15mn, it’s not ok
If I launch all 5mn, it’s ok.

Cdlt,

We use 5 minute polling, if you want to change to 15 minutes then follow http://docs.librenms.org/Support/1-Minute-Polling/
