The other approach is interesting but i have no experience with xinetd and it looks too complicated for what i need.
But thank you.

Well is extend-sh with snmpd is not something you want to do ( Which for
reasons, you are not using ) you have basicly 2 things you can do
- Passive checks: Cronjob runs your smartctl, then it sends a reply
to your Icinga server with status ( issue here is machines have to be
able to communicate to your icinga server, not the pratical choice for
security )
- Exposing the smartctl with xinetd on some ports. I do something
similar to check the Galera status of MariaDB servers with Haproxy.
Again not great for security, but you only have to whitelist your
Icinga2 server in firewall to access that port you expose. So your check
would do a http check on the port you chose, if status 200, means all
good, 500 or else means you have issue. you could also set a body in the
page to have perfdata/status details.
example xinetd
cat /etc/xinetd.d/mysqlchk # This file is being maintained by Puppet. #
DO NOT EDIT service mysqlchk { port = 9999 disable = no socket_type =
stream protocol = tcp wait = no user = nobody group = root groups = yes
server = /usr/local/bin/clustercheck only_from = 0.0.0.0/0 per_source =
UNLIMITED log_on_failure += USERID flags = REUSE }
And a sample return in the check it self
[...]
return_ok() { debug_log "return_ok()" echo -e "HTTP/1.1 200 OK\r\n" echo
-e "Content-Type: text/html\r\n" echo -e "Content-Length: 43\r\n" echo
-e "\r\n" echo -e "<html><body>MySQL is running.</body></html>\r\n" echo
-e "\r\n" rm $ERR_FILE $TMP_FILE exit 0 } return_fail() { debug_log
"return_fail()" echo -e "HTTP/1.1 503 Service Unavailable\r\n" echo -e
"Content-Type: text/html\r\n" echo -e "Content-Length: 42\r\n" echo -e
"\r\n" echo -e "<html><body>Node *down*: ${1}.</body></html>\r\n" sed -e
's/\n$/\r\n/' $ERR_FILE echo -e "\r\n" rm $ERR_FILE $TMP_FILE exit 1 }
[...]

That's not what I asked.
I meant what scenario, not what tools.
I have icinga2 running already but i'm not monitoring remote hardware,
only remote availability via icmp or tcp port (like http, pop, etc).
I was thinking maybe somebody does this on a large enough scale and can
recommend a theoretical setup based on personal experience with setup,
maintenance, ease of configuration, scalability, automation etc.
I didn't ask about man pages or command line parameters to plugins, no
thank you, I can read those myself.

Looks like nagios has a few smart monitoring plugins here:

They are likely available in your distributions package manager under a
name like "nagios-plugins".

Greetings,
I want to monitor several remote servers drives for SMART
errors and
also disk usage.
On icinga2, what scenario do you recommend ?
Thank you.
