Thanks Michael. I will make sure I turn off Monit on all my ALIX boxes.
I get that I can fine tune things to make them work but frankly for the money I think I will just change them all out to APU’s or not upgrade.

Hmm looks like Monit will need to go as nearly 15M.
Chrony is also fairly heavy on memory. Is this all I have in 1.2.10?
Do I disable SNMP by just removing mnt/kd/snmp/snmpd.conf ?
I have PHP using 45M plus. Is this normal? Anything I can do in php.ini?

Hmm Im a bit worried actually about upgrading to 1.2.10 with Asterisk 13 on my ALIX boxes.
Some sites showing 5M free.

Michael,

Since this is an ALIX box, (low RAM, low performance) best to not enable anything "extra" IMHO.

So do you think I should turn it off by default and only turn it on when I need it?

Hmm I liked it better before I implemented Monit. Blissful ignorance ☺

I got am email from one of my servers with the following:
Event:                    Resource limit matched
                                                               Service    3016-Tilton-CM1
               Date:        Tue, 29 Aug 2017 16:26:14
               Action:      alert

               Description: loadavg(5min) of 2.2 matches resource limit [loadavg(5min) > 2.0]

I found this in the logs of the server:

..... and lots more

Should I turn off the Netstat server? I assume this turns off darkstat!

Hi Michael,

I have a few Alix 2D13 PBX running in the field (with Asterisk 11 though). They usually have between 100 and 50 MB of free RAM.
I always create my own builds for them and leave out all packages that I don't need (e.g. netsnmp, Zabbix).

I also don't enable Monit on Geode CPUs, cause there are some memory related issues over a longer time period.

I you want I can send you my Buildroot .config file offlist.
Since there will be no official Alix/net5501 builds in the future, you need to build yourself anyway.

Michael
