[smokeping-users] One hour polling records data, but shows zero on graphs

[Adrian Popa]

Hello gentlemen,

I'm running a Smokeping instance where I have a bunch of probes that run 
every 5 minutes, and a specific probe that I need to run every hour. For 
this probe I have set step = 3600 in the config:

+ YoutubeDL
binary = /usr/local/bin/youtube-dl
timeout = 60
step     = 3600
pings    = 3

The RRDs created have step 3600 and minimal_heartbeat 7200, as expected. 
They record correct values for loss (which is zero for all 
measurements), median, ping1, ping2, ping3 (have values NaN and 1719 
unknown_sec).

The graph that gets drawn is a flat line at zero (green color).

Here is a dump of my rrd to get all the data: https://fnpaste.com/E1D9

Could anyone tell me:
1. Does having step set at 3600 forces polling to be done every hour 
(since the data has a minimum resolution of 1h? Or is smokeping polling 
every 5 minutes and agrregating that data to one data record?
2. What can I do about the graphs showing zero? I suspect it's because 
it has the same rrd structure as the stock '5 minute' rrd, but I haven't 
been able to define a custom database format for this probe. Any 
pointers on how to do that?

Also, examples of slower polling would be nice!

Regards,
Adrian
