# 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
|
|
* -t: timeout for RDAP requetss (in seconds)
|
|
|
|
## 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" = "$expiration_warning$",
|
|
"-t" = "$expiration_timeout$",
|
|
"-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.
