Ok, so how does this look...<br />

<div dir="auto">No, the Synology and the three servers are all on the one UPS (also my switch and spare monitor). All these are super low power devices (two Intel NUCs and a Raspberry Pi) so at idle the draw like 50-75w and at max load it’s like 100-150w tops. UPS is rated for 300w.<br /></div>

<div dir="auto">I changed it to this, thanks.<br />
<br />
So does everything look good with my config files? Any thoughts on what may be going on here? I really wish I could reproduce this, I think that’d make this a lot easier to troubleshoot. <br />
<br />
Thanks,<br />
<br />

I'm guessing that the UPS supplies only the NAS, not the 3 Ubuntu machines. Do<br />
they have their own UPS's?<br />
<br />
<blockquote type="cite">I have all three servers set as slaves, so is the Synology considered the<br />

confirm this.<br /></blockquote>
<br />
I've been looking at the Synology documentation and their NUT setup is not at<br />
all clear. Some of their site is nonsense. I gather from other sites that the<br />
NAS is indeed the master and that upsmon runs in the NAS. This makes sense if<br />
the UPS is for the NAS and nothing else. It also simplifies shutdown if NAS<br />
users mount NFS supplied directories in the NAS.<br />
<br />
<blockquote type="cite">So what I have done so far is enable the "Network UPS Server" on the Synology,<br />
entered the three IPs of the servers in there, set it to shutdown when battery<br />
is low and enabled "Shutdown UPS when the system enters safe mode". I then<br />
installed NUT on all three servers. In nut.conf I changed MODE to<br />
"MODE=netclient". I then added my MONITOR line in upsmon.conf. on all three. <br />
Looks something like this: <br />
<br />
MONITOR ups@192.168.1.70 1 monuser secret slave<br />
<br />
My SHUTDOWNCMD looks like this:<br />
SHUTDOWNCMD "getUPSstatus ups@192.168.1.70 ; logger -t upsmon.conf \"UPS status is $UPSstatus\" ; /sbin/shutdown -h +0" <br /></blockquote>
<br />
From your previous reports it looks as if getUPSstatus does not work in a<br />
SHUTDOWNCMD declaration since the shell variable it creates gets lost. It<br />
probably better to declare something like<br />
<br />
SHUTDOWNCMD "logger -t upsmon.conf \"UPS status [$( upsc ups@192.168.1.70 ups.status )]:$( upsc ups@192.168.1.70 )\" ; /sbin/shutdown -h +0" <br />
<br />
<blockquote type="cite">I think I've definitely made a mistake though, in that I have not set RUN_AS_USER in upsmon.conf<br /></blockquote>
<br />
The default user is usually set when NUT is built for a specific Linux<br />
distribution. I don't know what user Ubuntu have chosen, but I will guess that<br />
they have followed Debian and use "nut". I suggest you do not change this.<br />
<br />
<blockquote type="cite">and set up the appropriate permissions.<br /></blockquote>
<br />
Again, I assume Ubuntu build NUT with the correct file permissions for their<br />
default user.<br />
