Re: [Nut-upsuser] Accurate battery reports? (HP R3000 XR)
Hi NUT cgi started to report the battery at 100% without i remember doing anything.

Citeren Jon Bendtsen jbendt...@laerdal.dk: NUT cgi started to report the battery at 100% without i remember doing anything. It could be that the UPS has performed an automatic battery test or runtime calibration in the mean time (which is not unusual for many higher end devices). Note that in general, you'd be interested in changes in the trend, rather than absolute values. This not only counts for battery charge, but for most other readings as well. If there is a significant change in a value without you doing something, it's worth investigating what causes it.

[Nut-upsuser] Accurate battery reports? (HP R3000 XR)

Citeren Jon Bendtsen jbendt...@laerdal.dk: I have a HP R3000 XR UPS which NUT never says is at 100% battery. It seems stuck in 98 or 99 . something percentage. Please mention the driver you're using when asking for help. How accurate should i expect the reports to be? All my other UPSes has been and is at 100%, even those i have retired. Most drivers will report the value received from the UPS directly so you would have to ask the vendor/manufacturer about the accuracy of the readings. Some drivers attempt to calculate the battery charge themselves when the value is not reported by the UPS and generally there will be a note in the man page about which algorithm is used then. For basically all values that are reported, you should be looking at changes and trend lines, rather than absolute values. A UPS is not a measuring instrument and more often than not, the resolution of readings doesn't reflect the accuracy.

How accurate should i expect the reports to be? All my other UPSes has been and is at 100%, even those i have retired. This is something I have noticed during testing of the driver. My PW5115 is only going up to 90% and the PW5125 is at 98%. This is reported from the ups and i am not sure how this is measured. But in the config of the ups you have possibility to set the 'Max Battery Equalize Voltage' this is the highest voltage the battery get charged to. Protocol and info is now public at http://www.networkupstools.org/protocols/eaton/ The problem is at the moment the driver does not support setting this parameter. I hold back on this as it may damage the ups if it is not done in the right way. But you may hook up the settings program from powerware (Eaton) to make adjustments. is bcmxcp a eaton driver? My monitor system runs debian. The host that is physically connected to this ups runs: nut 2.2.2-6.4 The web script runs nut-cgi 2.0.4-4 If you can try the new 2.4.1, you have some more info from the ups, and better support for load-segments. And it would be fine for me if you can test it so it don't break the function of the HP XR series. sorry, the UPS is already in production usage. As for 2.4.1, i will get it eventually once it is in debian stable. I did try to upgrade to 2.4.1-3 from debian testing, but i had to change a lot to get it working, so i gave up and reverted to debian stable. ___ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
Re: [Nut-upsuser] Accurate battery reports? (HP R3000 XR)
OK Jon, just a comment. is bcmxcp a eaton driver? For some years ago Eaton purchased Powerware, but the driver was developed before that. On the nut 1.4 series it was Martin Schroeder that made the driver. But it was dropped, so i was sitting with some Powerware ups'es that I have to monitor. Tore Ørpetveit was getting some info from Powerware Norway, so in 2004 I and Tore started to rewrite the driver. Then Wolfgang Ocker added usb support. Oliver Wilcock sent me some patches for load segments (This code is rewritten, but he was pushing it in :-) ) HP and Compaq re-branded some Powerware equipment like the HP3000XR. sorry, the UPS is already in production usage. As for 2.4.1, i will get it eventually once it is in debian stable. I did try to upgrade to 2.4.1-3 from debian testing, but i had to change a lot to get it working, so i gave up and reverted to debian stable. OK, I fully understand that.
