Mam 3 problemy s Centreonem (resp. Nagiosem) a prosim Vas o pomoc:
- v konfiguraci služeb mi chybí pole ARGS pro pridani promennych parametru k prikazu
- nevykresluji se grafy (resp. necitelny png obrazek)
- a nedari se mi spustit command, ktery potrebuje prava roota (prostrednictvim sudo). Neznam spravnou syntaxi, z konzole OK
Diky za pomoc. Predpokladam, ze nejsem jediny, co pouziva Nagios v kombinaci s Centreonem.

Zdravim a dekuju za reakci. Vse mam nastaveno (postupoval jsem podle navodu), ale bohuzel problem pretrvava,. Jsem bezradnej
skript $USER1$/check_asterisk_peers -p 100poustim pres centreon v Configuration > Commands > Checks a vysledek je takovy:
Plugin test Command Line /usr/lib/nagios/plugins/check_asterisk_peers -p 100 Output CRITICAL: ?[0;37mUnable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?) ?[0m Status CRITICALALE, kdyz ho pustim v terminalu pod uzivatelem nagios (pod tim bezi i centreon) se
sudo (v /etc/sudoers mam potrebne udaje, tudiz na tento prikaz nepotrebuje uzivatel nagios heslo), vysledek je ok:
server:~# su nagios server:/$ whoami nagios server:/$ sudo /usr/lib/nagios/plugins/check_asterisk_peers -p 100 OK: 100Kam do toho commandu v centreonu mam zadat
sudo?
drwxrwsr-x 3 nagios nagios 20480 2011-07-15 18:52 libexec
drwxr-xr-x 3 root root 12288 20. čec 12.27 plugins
Takze to precte kazdy. Oni ty pluginy jdou spoustet, to je ok. Ale kdyz uz ten samotny plugin potrebuje prava roota, tak ho musim pustit pod sudo (/etc/sudoers mi resi to, ze neni zapotrebi vyzva k zadani hesla korektne). Ale to nevim, jak to z toho centreonu udelat, protoze tam pred command sudo nejde priradit.

Usage: check_asterisk_peers [--type | -t sip|iax] [--peers | -p peers] [--registrations | -r registrations] [--verify-peers] [--verify-registrations] [--config-file filepath]
Usage: check_asterisk_peers --help | -h
Description:
This plugin checks Asterisk peers via Asterisk CLI commands to make sure
they are in a healthy state. Unlike other monitoring plugins, status
is obtained from the perspective of the Asterisk server -- it's a good plugin
to use for monitoring the state of your connections to providers.
Both the peer itself and registration status to a peer can be monitored,
with the option of verifying that the peer/registration is actively configured.
If any of the checked peers/registrations return a non-OK state, a critical
state is returned. If verification is being used and a peer/registration is
not verified as being in the active configuration, then the status check is
skipped for that item instead of a critical state being returned.
Tested to work on Linux.
The following arguments are accepted:
--type | -t (Optional) The type of peer to check. Valid values
are sip, iax. Defaults to sip.
--peers | -p (Optional) A space separated list of peers to check.
Use the peer name given in the configuration,
without the surrounding brackets.
--registrations | -r (Optional) A space separated list of registrations
to check, in the form of username@uri. For example,
to check the registration of peer foo to
somesite.com, use foo@somesite.com
--verify-peers (Optional) If set, peer entries are verified in
the configuration, and the check is skipped
if they are not found.
--verify-registrations (Optional) If set, registrations are verified in
the configuration, and the check is skipped
if they are not found.
--config-file (Optional) The location of the configuration file(s).
Use a space separated list if specifying multiple
files.
Default value is based on the --type setting:
sip: /etc/asterisk/sip.conf
iax: /etc/asterisk/iax.conf
--help | -h Print this help and exit.
Examples:
Check peers [foo] and [bar]:
check_asterisk_peers -p \"foo bar\"
Check peers [foo] and [bar], and registration for usr baz at somesite.com,
and verify that both the peers and the registration are actively configured.
check_asterisk_peers -p \"foo bar\" -r \"baz@somesite.com\" --verify-peers --verify-registrations
Caveats:
The verification checks will not work correctly if there is any leading or
trailing whitespace on any of the register statement lines or the peer
section headings.
This plugin does not work with Realtime.
This plugin calls the asterisk executable directly, so make sure that the user
executing this script has appropriate permissions! Usually the asterisk binary
can only be run by the asterisk user or root. To grant the nagios user
permissions to execute the script, try something like the following in your
/etc/sudoers file:
nagios ALL=(ALL) NOPASSWD: /path/to/plugins/directory/check_asterisk_peers
Then call the plugin using sudo:
/path/to/sudo check_asterisk_peers

ASTERISK="/usr/bin/sudo /usr/sbin/asterisk"Zkus, jestli to pomuze...
sudo y centreonu pred script nejde jen tak napsat..
/usr/bin/sudo $USER1$/check_asterisk_peers -p 100nezkousel jsem, je to jenom napad
Také jsem se s tím trochu trápil a nakonec jsem to vyřešil tak, že jsem si udělal nový soubor, který volám z Centreonu a obsahuje to sudo.
Obsah souboru vypadá nějak takto:
#! /bin/sh
/usr/bin/sudo /usr/local/nagios/libexec/check_mailq -M 'qmail' -w '80' -c '100'
>> nevykresluji se grafy (resp. necitelny png obrazek) toto VYRESENO: problem s Centreonem a PHP 5.3 (funkce split je deprecated). Zeditoval jsem /etc/php5/apache2/php.ini a zmenil error_reporting = E_ALL & ~E_NOTICE na error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED podle navodu.
