Add an option to return the expiration date in unixtime (time since
epoch).
./check_expire -H domain -u
It's particularly useful for alerting or monitoring systems that do
their own calculation based on the metric they receive (and not based on
exit codes).
For instance you can use the following in zabbix 5.4:
- item: check_expire["-H","{HOST.CONN}","-u"]
- trigger: last(/check_expire["-H","{HOST.CONN}","-u"])-now()<2592000
Where 2592000 is 30 days in seconds.

# check_expire
|
|
|
|
A Nagios (and compatible) plugin to check the impending expiration of a domain name. It relies on RDAP exclusively (no whois) and works with every top-level domain with RDAP (which includes all the ICANN ones).
|
|
|
|
## Usage
|
|
|
|
check_expire follows the usual Nagios rules. The options are:
|
|
|
|
* -H: domain name to monitor
|
|
* -c: critical threshold in days
|
|
* -w: warning threshold in days
|
|
* -v: verbose details in output
|
|
* -u: unixtime output
|
|
|
|
## Installation
|
|
|
|
You need Python 3 and [Requests](http://python-requests.org/). You can install Requests, for instance, with pip `pip3 install requests`.
|
|
|
|
Then, copy the script `check_expire` and the file `ianardap.py`to the directory of local plugins.
|
|
|
|
## Icinga configuration
|
|
|
|
If you use Icinga, here is a possible definition of the command:
|
|
|
|
```
|
|
object CheckCommand "expiration" {
|
|
command = [ PluginContribDir + "/check_expire" ]
|
|
|
|
arguments = {
|
|
"-H" = "$address$",
|
|
"-c" = "$expiration_critical$",
|
|
"-w" = "$expiration_warning$",
|
|
"-v" = { set_if = "$expiration_verbose$" }
|
|
}
|
|
|
|
}
|
|
|
|
apply Service "expiration" {
|
|
import "generic-service"
|
|
|
|
check_command = "expiration"
|
|
|
|
assign where host.address && host.vars.monitor_expiration
|
|
}
|
|
```
|
|
|
|
And a possible use:
|
|
|
|
```
|
|
object Host "bortzmeyer-org" {
|
|
...
|
|
|
|
address = "bortzmeyer.org"
|
|
|
|
vars.monitor_expiration = true
|
|
vars.expiration_verbose = true
|
|
|
|
}
|
|
```
|
|
|
|
## Zabbix configuration
|
|
|
|
For monitoring systems that do not rely on exit codes but on calculation mechanism based on the metric they receive you can use the `-u` option that will only return the expiration date in unixtime format.
|
|
|
|
For instance, you can use the following in zabbix 5.4:
|
|
|
|
* item: `check_expire["-H","{HOST.CONN}","-u"]`
|
|
* trigger (30 days before expiration): `last(/check_expire["-H","{HOST.CONN}","-u"])-now()<2592000`
|
|
|
|
Where `2592000` is the number of seconds in 30 days.
