Nagios check_snmp " unrecognized option '--invert-search' "



When attempting to use the “--invert-search” option I received the error “ ./check_snmp: unrecognized option '--invert-search' ”.  Does this work with regular expressions?  Could you provide me with an example of how this should be used?.  Was there an update that added this option that I may need to install?


Best Regards,

Matthew Fairfield

check_procs Plugin



I have an issue where the user being queried is an Active Directory user. The UID for our AD users starts at 10000. I can run the command with the -u option for any locally authenticated user, and it works fine. I can even run the command check_procs with the -u and the AD user directly and it runs fine. However, if I use the check_nrpe and the -u option, it says user not found. Have you run into this before? If so, was there a work around? Are you aware of an nrpe user id limit? I haven’t found anything on it. If there is, may I have that, so I can make an exception for this user? This is on Linux.


Thank you,

check_cluster; verify servicestateID


I was trying to write a command definition for a large (80+ node) service cluster and no matter what args I pass in the "-d" flag, it seems to return OK. Is there a way for me to verify the correct servicestateID is getting retrieved from the cluster check?

Command is invoked thusly:

 [root <at> mon1 plugins]# ./check_cluster --service -d $SERVICESTATEID:cs01:custom-http$,$SERVICESTATEID:cs02:custom-http$,...$SERVICESTATEID:csNN:custom-http$ -w 30 -c 40
check_cluster - Warning: start=0 end=30; Critical: start=0 end=40
CLUSTER OK: Service cluster: 84 ok, 0 warning, 0 unknown, 0 critical

[check_ldap] Disable SSL common name verification


I'm trying to use the 'check_ldap' plugin to monitor an instance of an OpenLDAP server configured with StartTLS on port 389.
In my Nagios host definition, I've set the adresse of the server to a relative name such just 'servername' instead of full qualified domain name.
During the STARTTLS handshake the check plugin, return an error with the following message :

    additional info: TLS: hostname does not match CN in peer certificate

Using relative domain name as address for host definition is convenient and I can't use the full qualified domain name instead.

Is there any way t disable SSL common name verification by using extra opts ?

Thanks by advance

check_http with basic auth on server without an "authentication challenge"


Many years ago, I had the check_http plugin working to monitor a very basic
network printserver.  At that point, I was using monitoring the printer server's
existence with ping and check_http.

Some time ago, I didn't need/want it anymore so I put it in a box.

Now, I have taken it out again, and wanted to monitor it.

Currently running icinga2 on openbsd current with monitoring plugins:

# /usr/local/libexec/nagios/check_http -V
check_http v2.1.2 (monitoring-plugins 2.1.2)

# uname -mrsv
OpenBSD 5.9 GENERIC.MP#1982 amd64

# icinga2 -V
icinga2 - The Icinga 2 network monitoring daemon (version: r2.4.4-1)

Anyway, trying to use basic auth with check_http fails for this print server.

I have another (even older, but maybe not quite as cheap) print server that is
monitored fine.

On the "working" one, I can confirm check_http works with:

# /usr/local/libexec/nagios/check_http -I -v -a user:pass
GET / HTTP/1.0
User-Agent: check_http/v2.1.2 (monitoring-plugins 2.1.2)
Connection: close
Authorization: Basic U0M0MTc2OTg6dHlyb25l
HTTP OK: HTTP/1.0 200 Document follows - 3905 bytes in 1.032 second response
time |time=1.032029s;;;0.000000 size=3905B;;;0

But, when I try confirming this on the "non-working" print server with:

# /usr/local/libexec/nagios/check_http -I -v -a user:pass
GET / HTTP/1.0
User-Agent: check_http/v2.1.2 (monitoring-plugins 2.1.2)
Connection: close
Authorization: Basic YWRtaW46TWR1S3dadDc=

CRITICAL - Socket timeout after 10 seconds

When I use wget I was also getting the same discrepancy; wget pulled down the
page for the "working" print server, but not the "non-working" one.

Eventually, I was able to discover that the issue with wget was the need for the
"--auth-no-challenge" switch.

It appears this print server does not send an authentication challenge; but
simply expects the basic auth credentials to be sent.  From the wget man page:

           If this option is given, Wget will send Basic HTTP authentication
           information (plaintext username and password) for all requests,
           just like Wget 1.10.2 and prior did by default.

           Use of this option is not recommended, and is intended only to
           support some few obscure servers, which never send HTTP
           authentication challenges, but accept unsolicited auth info, say,
           in addition to form-based authentication.

So, it seems that this old "non-working" print server does not send an
authentication challenge.

I am not sure if this is relevant to check_http, but some prior version of
check_http worked with this piece of hardware many years ago, but does not any

Is there anything I can do to get check_http working in this situation, or
should I just abandon http checks for this hardware?

Fw: Fehlende Checks in Monitoring_Plugin nach Installation

Hallo Zusammen,

ich hoffe bei Ihnen Lösung meines Problems zu finden:

Versuchsweise habe ich auf Centos 7x64 Icinga2, Icingaweb2 (v.2.3.1), Director (v.1.0.0) installiert.

Dazu habe ich Monitoring_plugins (v.2.1.2) installiert:

# ./configure --with-nagios-user=icinga --with-nagios-group=icinga

# make

# make install

Die installation ist problemlos gelaufen (bis jetzt habe ich so gedacht)

Als ich angefangen die Services zu definieren, habe ich festgestellt, dass mind. 2 Checks  (check_mysql und check_ldap)
zwar in Icinga Director zu sehen sind, aber in Plugin Verzeichnis "/usr/local/libexec" sind die nicht zu finden.

# ls /usr/local/libexec/
check_apt         check_icmp                check_nagios      check_smtp                     
check_breeze    check_ide_smart          check_nntp        check_snmp                      check_ssh
check_by_ssh    check_ifoperstatus      check_nt            check_snmp_boostedge.pl    check_swap
check_clamd      check_ifstatus           check_ntp           check_snmp_cpfw.pl           check_tcp
check_cluster     check_imap                check_ntp_peer  check_snmp_css_main.pl      check_time
check_dbi          check_ircd                  check_ntp_time  check_snmp_css.pl             check_udp
check_dhcp       check_ldap_connect    check_nwstat     check_snmp_env.pl             check_ups
check_disk         check_ldap.pl             check_oracle      check_snmp_int.pl               check_users
check_disk_smb  check_load                check_overcr      check_snmp_vrrp.pl             check_wave
check_dummy     check_log                 check_ping         check_snmp_load.pl              libexec
check_file_age    check_mailq               check_pop         check_snmp_mem.pl             negate
check_flexlm       check_mrtg               check_procs       check_snmp_nsbox.pl           urlize
check_ftp           check_mrtgtraf          check_real         check_snmp_process.pl        utils.pm
check_hpjd         check_mssql_health    check_rpc          check_snmp_storage.pl        utils.sh
check_http         check_mysql_health    check_sensors    check_snmp_win.pl

Gibt es für diese Checks irgendwelche Abhängigkeiten, die mir bis jetzt nicht bekannt sind, oder sind mir in der Installation Fehler unterlaufen?

Danke für Antwort voraus.

Mit freundlichen Grüßen
Artur Symowski
