Hi I was wondering if anyone know how to setup ping tests to Dynamic ips / host names. Currently i've got it setup to monitor static ip addresses but just got a new unit thats dynamic.
host setups I have now:
define host{
use server
host_name testname.test.com
alias test
address 172.xx.xx.xxx ; ip address
}
I was wondering if theres a way to set it up like this:
define host{
use server ; It’s much easier to assign a profile because it will know what to monitor
host_name testcomputer.Test
alias testcomputer
address testcomputer.test
}
Setup alerts to monitor Dynamic hosts
Re: Setup alerts to monitor Dynamic hosts
If you have a dynamic dns implementation that should work. And testing should be straightforward enough. Let us know if it works as expected.
Thank you!
Thank you!

Pretty new at this, not sure if I do. How would I go about checking that

ping testcomputer and see if it resolves the hostname to an IP address.

The plugin
Code: Select all
check_dns
Please see usage below:
Code: Select all
This plugin uses the nslookup program to obtain the IP address for the given host/domain query.
An optional DNS server to use may be specified.
If no DNS server is specified, the default server(s) specified in /etc/resolv.conf will be used.
Usage:
check_dns -H host [-s server] [-q type ] [-a expected-address] [-A] [-n] [-t timeout] [-w warn] [-c crit]
Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
--extra-opts=[section][@file]
Read options from an ini file. See
https://www.nagios-plugins.org/doc/extra-opts.html
for usage and examples.
-H, --hostname=HOST
The name or address you want to query
-s, --server=HOST
Optional DNS server you want to use for the lookup
-q, --querytype=TYPE
Optional DNS record query type where TYPE =(A, AAAA, SRV, TXT, MX, ANY)
The default query type is 'A' (IPv4 host entry)
-a, --expected-address=IP-ADDRESS|HOST
Optional IP-ADDRESS you expect the DNS server to return. HOST must end with
a dot (.). This option can be repeated multiple times (Returns OK if any
value match). If multiple addresses are returned at once, you have to match
the whole string of addresses separated with commas (sorted alphabetically).
If you would like to test for the presence of a cname, combine with -n param.
-A, --expect-authority
Optionally expect the DNS server to be authoritative for the lookup
-n, --accept-cname
Optionally accept cname responses as a valid result to a query
The default is to ignore cname responses as part of the result
-w, --warning=seconds
Return warning if elapsed time exceeds value. Default off
-c, --critical=seconds
Return critical if elapsed time exceeds value. Default off
-t, --timeout=INTEGER:<timeout state>
Seconds before connection times out (default: 10)
Optional ":<timeout state>" can be a state integer (0,1,2,3) or a state STRING

Re: Setup alerts to monitor Dynamic hosts
how is your dhcp setup? how about DNS? you should look for something similar to this - https://technet.microsoft.com/en-us/lib ... s.11).aspxNagiosNoob89 wrote:Pretty new at this, not sure if I do. How would I go about checking that
