Hi DavidH,

I'd go with a setup where collectd is sending metrics via network to a
central location, that can be a prometheus for example (which is pulling
for metrics, to be exact).
You could then use your device of choice to visit that site.

Collectd is has a list of write targets, and if the write did not
succeed, it will try again. Until this is successful, it stores the
metrics (by default).

prometheus runs fine on even small devices.

A side remark: collectd never spelled with an upper-case 'D' at the end.
Where did you read it that way?
