Here is my configuration (As i now will be at home ) owfs.conf is: error_print = 3 error_level = 0 format = f.i cache_size = 0 Celsius foreground allow_root owfs: server = 127.0.0.1:4304 owfs: pid_file = /var/run/owfs.pid owfs: mountpoint = /mnt/1wire server: usb server: port = 127.0.0.1:4304 server: pid_file = /var/run/owsever.pid http: server = 127.0.0.1:4304 http: port = 8080 http: pid_file = /var/run/owhttpd.pid
By collectd i have the config for onewire: LoadPlugin onewire <Plugin onewire> Interval 5 Device "-s 127.0.0.1:4304" </Plugin> Best regards, Roland From: Roland Franke Sent: Wednesday, October 29, 2014 10:07 AM To: OWFS (One-wire file system) discussion and help Subject: Re: [Owfs-developers] Missing data Hello, i build owfs (Now 2.9p8) together with collect (now 5.4.1) with an buildroot System for my x86 (32bit) softwarerouter (www.fli4l.de). In that i have activate OWSERVER; OWHTTPD and OWFS. My USB-Adapter is set for be using with OWSERVER and OWHTTPD and OWFS will be connected to the OWSERVER (But similar timeouts i will get without OWSERVER and OWHTTPD, when i connect my USB Adapter directly to the OWFS) By the onwire-plugin i made an modification, so that this can read more sensor-tyes as only type 10 (I use type 28, but also type 31 and else). Now the opnewire-plugin read in the data directly over the libowfs (There is no seperate program from me made for that). Please note, that i am be also only an "user" from different ready Systems (From the main programming) and have also only used some script for the preparemend here. But the main collection of the data over collectd with the libowfs was not touched or changed from me. Best regards, Roland > Gregg Levine <gregg.drw...@gmail.com> hat am 29.
