Hello everyone!
Update: After the changes I did yesterday the data was stored correctly.
Only the overview graphs had missing/wrong data, but it was fixed by
setting
max_rtt = 1000000000
in the overview section. Now all graphs are ok.
@Tobi: If I make the changes to the "max" setting in the rrd in the
github code would you consider a pull request to remove the rrd limits
(or do you want to do it yourself)?
I will also release the plugins I've been working on in the near future
- they could be included in the core plugins if you'd like/if people
find them useful.
Regards,
Adrian

Hi Adria,
yes, there are a few assumptions about timeing hardcoded in
smokeping ... but you can certainly relax them ...

Hello everyone!
I'm writing some custom plugins for smokeping that don't measure time, but
measure bps (one plugin does periodic speedtests with speedtest.net). The
values returned are usually in the 10^6 range (Mbps).
I noticed that the plugin works correctly, returns the data in the correct
format, but it doesn't get stored in the rrd:
ds[ping1].index = 3
ds[ping1].type = "GAUGE"
ds[ping1].minimal_heartbeat = 7200
ds[ping1].min = 0.0000000000e+00
ds[ping1].max = 1.8000000000e+02
ds[ping1].last_ds = "2.3910000000e+08"
ds[ping1].value = NaN
ds[ping1].unknown_sec = 92
last_ds is correct, but I guess rrdtool ignores it because it's higher than
"max".
I've looked in the code where it sets the max value, and it's hardcoded to
180:
Smokeping.pm:560: "DS:median:GAUGE:".(2*$step).":0:180",
Smokeping.pm:561: (map {
"DS:ping${_}:GAUGE:".(2*$step).":0:180" }
I wonder - why is the need to hardcode it to 180? I understand most probes are
fast and return small numbers, but - is there any benefit from setting a max
value, and not setting max to "U"?
I will change my code to have it set to U and report back if the problem
persists (I expect there will be problems with the Y scale, but we'll see...
Regards,
Adrian
