---------------------------------------------------------------
|
||||
With this check plugin / script, Nagios can monitor the replication of DNS zones
|
||||
between the authoritative DNS server for a domain and one or more of it's slave
|
||||
(or secondary) DNS servers. The script can check one or multiple DNS zones and
|
||||
can be pointed at one ore more specific DNS slave server(s) or us the NS records
|
||||
of the zone to check all DNS servers of that domain (or a combination of this)
|
||||
|
||||
The script expects a (comma separated list of) DNS zone(s) to validate as its
|
||||
first command line parameter. It optionally also accepts one or more DNS servers
|
||||
to check as further parameters (either separate parameters or comma separated).
|
||||
If no DNS Servers are provided or the `-n` command line option is passed it will
|
||||
lookup the DNS Servers from the NS records in de DNS zone.
|
||||
|
||||
The script will first fetch the authoritative DNS server from the SOA record, so
|
||||
that server must be reachable. This first lookup will be done against the first
|
||||
DNS server, if provided, or the default nameserver of the host. Next it will
|
||||
fetch the DNS zone's SOA record from each server and compare it with the master.
|
||||
|
||||
Installation is straightforward, after installing the script on your server, add
|
||||
the following to your `commands.cmd` configuration file to make it available:

||||

most sensors require some configuration to make them available:

* No setup is required to read the CPU temperature.

|

* To enable 1-wire interface support on the RaspberryPi use the command:
|
||||
|
||||
~~~
|

sudo raspi-config nonint do_onewire 0
|
||||
~~~
|
||||
or use `raspi-config` in interactive mode (9. Advanced Options --> A9. 1-Wire).
|
||||
Please note that changing this requires a reboot.
|
||||
~~~
|
||||
|
||||
Installation for is straightforward, after installing the script on the server
|
||||
add the following to your Nagios `commands.cmd` configuration file:
|
||||
or use `raspi-config` interactively (1. Interfacing Options --> P7. 1-Wire).
|
||||
Please note that changing this requires a reboot.
|
||||
|
||||
* To enable I2C interface support on the RaspberryPi use the command:
|
||||
|
||||
~~~
|
||||
sudo raspi-config nonint do_i2c 0
|
||||
~~~
|
||||
|
||||
or use `raspi-config` interactively (1. Interfacing Options --> P5. I2C).
|
||||
Please note that changing this requires a reboot.
|
||||
The I2C interface also requires the `SMBus` or `SMBus2` library, to install
|
||||
the `SMBus` library on Raspbian Linux run:
|
||||
|
||||
~~~
|
||||
sudo apt install python-smbus
|
||||
~~~
|
||||
|
||||
`SMBus2` is a pure Python implementation that requires system-wide or a
|
||||
`virtualenv`-based installation, less trivial than installing the package.
|
||||
|
||||
Configuration of Nagios to use the script is straightforward, after installing
|
||||
the script on the server add the following to your Nagios `commands.cmd`
|
||||
configuration file to enable checking the CPU temperature:
|
||||
~~~
|
||||
# 'check_cpu_temperature' command definition to monitor CPU temperature in C
|
||||
# parameters: warning (ARG1) and critical (ARG2) temperature in Celcius
|
||||

|
||||

||||

|

command_line [install_path]/plugins/check_temperature -F -w $ARG1$ -c $ARG2$ rpi_cpu
|
||||
}
|
||||
~~~
|
||||
|
||||
To monitor a supported temperature sensor on its default address, add:
|
||||
~~~
|
||||
# 'check_temperature' command definition to monitor a single temperature in C
|
||||
# parameters: warning (ARG1) and critical (ARG2) temperature in Celcius
|
||||
define command {
|
||||
command_name check_temperature
|
||||
command_line [install_path]/plugins/check_temperature -w $ARG1$ -c $ARG2$ w1_ds18b20
|
||||
command_name check_cpu_temperature
|
||||
command_line [install_path]/plugins/check_temperature -w $ARG1$ -c $ARG2$ <<sensor>>
|
||||
}
|
||||
|
||||
# 'check_ftemperature' command definition to monitor a single temperature in F
|
||||
# parameters: warning (ARG1) and critical (ARG2) temperature in Farenheit
|
||||
define command {
|
||||
command_name check_ftemperature
|
||||
command_line [install_path]/plugins/check_temperature -F -w $ARG1$ -c $ARG2$ w1_ds18b20
|
||||
command_name check_cpu_temperature_f
|
||||
command_line [install_path]/plugins/check_temperature -F -w $ARG1$ -c $ARG2$ <<sensor>>
|
||||
}
|
||||
~~~
|
||||
With `<<sensor>>` replaced by the sensor, e.g. w1_ds18b20 for a 1-wire DS18B20,
|
||||
i2c_mcp9808 for an I2C MCP9808 sensor or i2c_bme280 for an I2C BME280. Run
|
||||
`check_temperature -h` to get the list of supported sensors. In case you have
|
||||
multiple sensors, add a separate definition for each sensor with a different
|
||||
value for `command_name`.
|
||||
|
||||
If you need to pass on additional parameters, e.g. the sensor serial for an
|
||||
1-wire DS18B20, you can do that like this:
|
||||
~~~
|
||||
# 'check_temperature_sensor' command definition to monitor a single temperature in C
|
||||
# parameters: sensor serial (ARG1), warning (ARG2) and critical (ARG3) temperature in Celcius
|
||||
define command {
|
||||
command_name check_temperature_sensor
|
||||
command_name check_ds18b20_sensor
|
||||
command_line [install_path]/plugins/check_temperature -w $ARG2$ -c $ARG3$ w1_ds18b20 -s $ARG1$
|
||||
}
|
||||
|
||||
# 'check_ftemperature_sensor' command definition to monitor a single temperature in F
|
||||
# parameters: sensor serial (ARG1), warning (ARG2) and critical (ARG3) temperature in Farenheit
|
||||
define command {
|
||||
command_name check_ftemperature_sensor
|
||||
command_name check_ds18b20_sensor_f
|
||||
command_line [install_path]/plugins/check_temperature -F -w $ARG2$ -c $ARG3$ w1_ds18b20 -s $ARG1$
|
||||
}
|
||||
|
||||
~~~
|
||||
|
||||
Likewise, to pass the I2C address for an I2C MCP9808 use something like:
|
||||
~~~
|
||||
# 'check_temperature_sensor' command definition to monitor a single temperature in C
|
||||
# parameters: sensor address (ARG1), warning (ARG2) and critical (ARG3) temperature in Celcius
|
||||
define command {
|
||||
command_name check_mcp9808_sensor
|
||||
command_line [install_path]/plugins/check_temperature -w $ARG2$ -c $ARG3$ i2c_mcp9808 -a $ARG1$
|
||||
}
|
||||
|
||||
# 'check_ftemperature_sensor' command definition to monitor a single temperature in F
|
||||
# parameters: sensor address (ARG1), warning (ARG2) and critical (ARG3) temperature in Farenheit
|
||||
define command {
|
||||
command_name check_mcp9808_sensor_f
|
||||
command_line [install_path]/plugins/check_temperature -F -w $ARG2$ -c $ARG3$ i2c_mcp9808 -a $ARG1$
|
||||
}
|
||||
|
||||
~~~
|
||||
|
||||
For the list of supported sensors run `check_temperature -h` and to get the
|
||||
options sensor ``<<sensor>>`` supports run `check_temperature <<sensor>> -h`.
|
||||
|
||||
Make sure to replace `[install_path]/plugins` with the location of the script.
