Probably, I am looking to monitor things not available with zabbix-agent like systemd, zabbix-agent2 does.
Salut!
If I can help Stephdl setup a Zabbix monitoring system, sure!
A small payback for all the great code Stephdl has written!
Just PM me…

basically I did
monitor postfix
monitor systemd
send alert to telegram because my email server could be down
monitor LVM/RAID
@mrmarkuz is in the loop, if you have Templates or tricks, please shoot

@Andy_Wismer What do you think about using zabbix-agent2 instead of zabbix-agent? Is it safe?
Does it make sense to integrate some typical NethServer app checks, like Nextcloud?
What I use in check_mk and where I didn’t find a counterpart in Zabbix yet:
Some user login check like a webdav check for Nextcloud would be nice because it’s a more reliable check than just service running and it checks the account provider too.
I’d also like a mail loop test to check if a mail goes from some smtp server to another imap server.
Last resort is integrating SMS via mobile or GSM gateway because www could be down…

Hi Markus
Zabbix has a very good track record so far, both on security, reliability and also update reliability…
I’d say it’s safe, but I’d like to do a bit more testing…
I have a new Proxmox hardware at home, so far everything is working satisfactorily…
These can be done, both are good ideas as a standard, so is integrating a sms fallback…
Some user login check like a webdav check for Nextcloud would be nice because it’s a more reliable check than just service running and it checks the account provider too.
I’d also like a mail loop test to check if a mail goes from some smtp server to another imap server.
I have some more ideas, I’ll put these in a seperate post…
My 2 cents

Did you already try zabbix-agent2 ?
Great.
@syntaxerrormmm do you have some ideas about the 2 zabbix agents or good checks to integrate?
the configuration of agent2 is nearly similar, I dropped the postfix template to the new folder of agent2, AFAIK it is workable.
It seems agent2 can do smartctl check for drives too
I would like to know how to import a template with an API inside zabbix, we have backend files, we know how to import them, a rpm and it is over, but templates for now need to be enabled manually. Hence my interest.
The GSM gateway could be a nice toy

I found an easy way with zabbix-cli (Download).
Create the file $HOME/.zabbix-cli_auth containing credentials:
Admin::zabbix
Import Template_Systemd.xml:
zabbix-cli -C "import_configuration Template_Systemd.xml 0"
You may use an old mobile phone with an sms web gateway app too.

Cool, we could imagine a rpm to bundle extra templates and backends needed to monitor what we want on a nethserver. These plugin exist but need to be adapted to the distro path or sometimes be fixed like I did for Postfix.
This rpm will be extra, no require in it, you install it if you want
Relative to the gsm I need to do something for this, one day, I would like a multiwan.
Hi
MultiWAN with GSM is easily possible, at least for outgoing. AFAIK, in most of Europe, on 4G/LTE, incoming is NOT possible. Most Telcos (or all) in Europe use Provider-NAT for the 4G/LTE networks, meaning you’ll get a 10.x.x.x IP on your WAN, not a real Internet routable IP. So NAT will NOT work.
I’ve tested this for Switzerland and Germany with a few Providers. The Huawei Mobile Hotspot (The model with LAN connection) allows “Port Forwarding”, but as the Providers I tested use Provider NAT with a 10.x.x.x IP, this will not work for incoming traffic.
What WILL work is a VPN, if initialized from the LAN side. (Outgoing works).
Any experiences from elsewhere, or other continents?
My 2 cents

Look for “two-way APN”. It’s usually a really not cheap option for mobile connections and is reserved for some special applications.
Also… IPv6 is coming…

Did you ask the Provider-Support if it is possible to deactivate the NAT? I use drei.at and it is possible, they call it “open internet”…
I did try, but the two providers I had available both did not have this option…
We only have 3 mobile providers in Switzerland…
This is why I am not hurry to go, mainly it is for people behind the router to continue to work, If I put my mobile in router mode it is the same. For a team it makes sense, for me at home even if I have to work it is not a first priority, of courser for the fun I would like to do it.
I have the box for emergencies, and a second one for working “On the road”, as both have unlimited Internet. My phone is limited…
And I often work with more than one box or notebook, eg Mac / Linux…
This way, both “see” each other and both have Internet…
This is true for the first installation but not for former installations

I think we could create a user for zabbix-cli with password saved in /var/lib/nethserver/secrets on first install. For existing installations one may need to create the user manually.
