They all sound dramatic! What do I do with it all ?!

And where are you seeing these errors?

It is FreeNAS. It is a name not just a collection of letters.

Got email allerts with them. Nice colorfull Red/Orange/Green emails :- )

 

[Chris Moore]

The Netdata service is creating those emails. It doesn't work properly in 11.2. I don't know if anyone filed a bug, but I think they should have. It has been discussed on the forum before.

 

[Dariusz1989]

Interesting, so they are nothing I should "panic" about I take? Looks like they are set to panic when stuff runs at 90% - well in ram case, not sure what to think of teh tcp/udp ones and system.swapio... hmm

I can't say definitively, but I think it is just that the alert levels are not where they should be considering the way that FreeNAS works. The last person that reported this just turned it off so they stopped getting emails. If you would do some investigation and report back, it might help fix the problem in future.

 

[Dariusz1989]

Sounds good thanks! Will dig in to it a little.

<mod hat>

That's not really that helpful and could be taken badly. Alternative suggestion:

"Please note, the name is FreeNAS, which roughly means Free Network Attached Storage, or possibly FreeBSD-based Network Attached Storage, depending on how you roll."

I was getting some of these messages. I did a google search and found this thread. I figured I would add my recent alerts here in case it would help someone..

It might be worth mentioning that the udp and tcp was after starting a scp session with some fairly large files in them. If it happens again I will take a closer look at the tcp and udp issues. As for the ram alert. I set those to silent cause I know ZFS uses a lot of ram and netdata is just not used to that being normal. For others you can find alerts here

Code:

 /usr/local/etc/netdata/health.d

The footer of the netdata emails will show you what created the alert and you can edit the .conf file to silence them *if* you are sure that the issue is "normal" for FreeNAS.

Hopefully this helps and isn't just a dup of another thread.
