[Nut-upsuser] using nut in cacti
Hi. Are there any off-the-shelf solutions to monitor nut ups' with cacti? I suppose snmp could be used, but since upsc can be run locally in the cacti server, it might be easier to use a simple script.

[Nut-upsuser] tracing a problem with newhidups
Hi. I'm having trouble with nut-2.0.3 on a linux kernel 2.4.32 machine and a
MGE Evolution 3000. The problem is that I'm getting the following message,
repeatidly, on dmesg:
usbdevfs: usb_submit_urb returned -22
(-22 means -EINVAL)
I traced the problem with newhidups -DD auto and found out that the -22
error appears in a line none (-22) of the output as:
--
upsdrv_updateinfo...
Waiting for notifications...
none (-22)
entering string_to_path()
parsing UPS
Looking up UPS
--
The function calls in userspace are:
[newhidups.c] upsdrv_updateinfo()
[libhid.c] HIDGetEvents()
[libusb.c] libusb_get_interrupt()
[libusb] usb_interrupt_read()
[libusb] usb_urb_transfer()
In the usb_urb_transfer() function one can find that
--
urb.number_of_packets = 0; /* don't do isochronous yet */
urb.usercontext = NULL;
ret = ioctl(dev-fd, IOCTL_USB_SUBMITURB, urb);
--
and in the kernel code of linux/drivers/usb/host/uhci.c:
--
static int uhci_submit_urb(struct urb *urb)
[...]
case PIPE_ISOCHRONOUS:
if (urb-bandwidth == 0) { /* not yet checked/allocated
*/
if (urb-number_of_packets = 0) {
ret = -EINVAL;
--
So it seems that setting number_of_packets to zero is directly related with
the kernel error.
What is going on here? Is it a bug in nut?
Cheers,
Rodrigo

I'm using Linux kernel 2.4.32 and nut-2.0.3. Can you describe your setup a little more? Do you have other USB devices in the system? Are they plugged into the same external or root hub? Sure. The machine is a Compaq Proliant ML350 (G3), P4 Xeon, the UPS is the only device on the bus. It is the central server of the institution, running all mail (MTA and IMAP), UNIX accounts, and user web pages.

[Nut-upsuser] MGE Evolution, USB and linux
I have a MGE Evolution 3000 connected via USB to a linux server (HP Proliant G3). The server is running kernel 2.4.30 and nut-2.0.3. But before nut trying to connect to the UPS, I guess HID doesn't work as long as I get a message like this in dmesg: -- usb.c: new device strings: Mfr=4, Product=136, SerialNumber=50 usb.c: USB device number 2 default language ID 0x409 Manufacturer: MGE UPS SYSTEMS Product: Evolution SerialNumber: AF3G03062 usb.c: unhandled interfaces on device usb.c: USB device 2 (vend/prod 0x463/0x) is not claimed by any active driver.
