Gaps in graphs when changed from 5 min to two min polling

[Kristoffer_Fagerlund]

After chaning to 2 minutes polling from 5 I get gaps in the RRD graphs

Polling time for this specific device:

Cron:
> 33 */6 * * * librenms /opt/librenms/cronic /opt/librenms/discovery-wrapper.py 1
> */5 * * * * librenms /opt/librenms/discovery.php -h new >> /dev/null 2>&1
> */2 * * * * librenms /opt/librenms/cronic /opt/librenms/poller-wrapper.py 32

> */5 * * * * librenms /opt/librenms/poll-billing.php >> /dev/null 2>&1
> 01 * * * * librenms /opt/librenms/billing-calculate.php >> /dev/null 2>&1
> */5 * * * * librenms /opt/librenms/check-services.php >> /dev/null 2>&1

I ran “./scripts/rrdstep.php -h all” after changing the settings.

Why two minutes and not one? I have about 3 devices that sometimes polling takes longer then 60s, avg is 30s.

Polling time is ok as you saw in my first post.

here again:

btw the single most important thing to add is a local dns cache, ie powerDNS , that lowered my polling time from 100ish to a few seconds per device.

Settings the polling time to one minute fixes the gaps in the graphs, I was using two minutes before. Maybe it was the script that converts the RRD files that was hardcoded for 60s.
