j’ai resolu le prbl de permission, & j’arrive a démarrer Nagios. Mais, quand je lance l’interface web, je n’arrive pas a monitorer le reseau & je recois un messages d’error:
:x
Error: Could not read host and service status information!
The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you’ve just installed things, make sure you read the documentation on starting Nagios.
je check que nagios est up avec la commande :
[root@audit /]# ps -ef|grep nagios

Je n’arrive pas a comprendre pourquoi la commande ping ne marche pas… voila comment je l’ai defenie dans le fichier commands.cfg
‘check_ping’ command definition
define command{
command_name check_ping
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5
}
je refere a la commande dans le fichier services.cfg :
###############################################################################
Ping Test
###############################################################################
Service definition for Ping Tests
define service{
use generic-service ; Name of service template to use
host_name msebbane,bnassreddin,redouane,Linux,linux1
service_description PING
is_volatile 0
check_period 24x7
contact_groups apache
notification_options w,u,c,r
check_command check_ping
}
dans le fichier resources, j’ai specifier l’emplacement des plugins :
Sets $USER1$ to be the path to the plugins
$USER1$=/usr/local/nagios/libexec
j’ai aussi telecharger les plugins necessaire & installer sous /usr/local/nagios/libexec
[root@audit /]# ls /usr/local/nagios/libexec
check_breeze check_http check_nagios check_real check_ups check_by_ssh check_ifoperstatus check_nntp check_rpc check_users
check_dig check_ifstatus check_nt check_sensors check_wave check_disk check_imap check_ntp check_smtp
negate check_disk_smb check_ircd check_nwstat check_ssh urlize
check_dns check_load check_oracle check_swap utils.pm check_dummy check_log check_overcr check_tcp utils.sh check_file_age check_mailq check_ping check_time
check_flexlm check_mrtg check_pop check_udp
check_ftp check_mrtgtraf check_procs check_udp2
Quand le lance nagios avec l’option -v, il donne 0 erreurs & 0 warning:
***[root@audit /]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg ***
***Nagios 1.2
