Kako dodati Windows host Nagios poslužitelju za praćenje

Koristite donje upute za instalaciju NSClient++ Agent na Udaljeno Windows računalo. Najprije preuzmite najnoviju stabilnu verziju NSClient++ 0.3.1 izvornih datoteka dodatka, koje se mogu pronaći na donjoj poveznici.

1. http://sourceforge.net/projects/nscplus/

Nakon što preuzmete najnoviju stabilnu verziju, raspakirajte NSClient++ datoteke u novi C:\NSClient++ direktorij.

Sada otvorite MS-DOS naredbeni redak iz Početnog zaslona –> Pokreni –> upišite 'cmd' i pritisnite enter i prijeđite na direktorij C:\NSClient++.

C:\NSClient++

Zatim registrirajte uslugu NSClient++ na sustavu pomoću sljedeće naredbe.

nsclient++ /install

Na kraju, instalirajte NSClient++ sistemsku traku pomoću sljedeće naredbe.

nsclient++ SysTray

Otvorite Windows Services Manager i desnom tipkom miša kliknite NSClient idite na Properties i zatim 'Log On' karticu i kliknite potvrdni okvir koji kaže “Dopusti interakciju usluge s radnom površinom“. Ako već nije dopušteno, označite okvir da biste to dopustili.

Otvorite datoteku NSC.INI koja se nalazi u direktoriju C:\NSClient++ i uklonite komentare sa svih modula definiranih u odjeljku “moduli”, osim za Provjerite WMI.dll i RemoteConfiguration.dll.

;NRPEClient.dll

Odkomentirajte “allowed_hosts” u odjeljku “Postavke” i definirajte IP adresu vašeg Nagios poslužitelja za praćenje ili ostavite prazno kako biste dopustili bilo kojem hostu da se poveže.

[Settings]
;# ALLOWED HOST ADDRESSES
;  This is a comma-delimited list of IP address of hosts that are allowed to talk to the all daemons.
;  If leave this blank anyone can access the deamon remotly (NSClient still requires a valid password).
;  The syntax is host or ip/mask so 192.168.0.0/24 will allow anyone on that subnet access
allowed_hosts=172.16.27.41

Odkomentirajte “port” u odjeljku “NSClient” i postavite na zadani port ‘12489’. Obavezno otvorite port ‘12489’ na vatrozidu Windows.

[NSClient]
;# NSCLIENT PORT NUMBER
;  This is the port the NSClientListener.dll will listen to.
port=12489

Na kraju pokrenite uslugu NSClient++ sljedećom naredbom.

nsclient++ /start

Ako ste ispravno instalirani i konfigurirani, trebali biste vidjeti novu ikonu u traci sustava u žutom krugu s crnim 'M' unutra.

Korak 2: Konfiguriranje Nagios poslužitelja i dodavanje Windows hostova

Sada se prijavite na Nagios poslužitelj i dodajte neke definicije objekata u Nagios konfiguracijske datoteke za nadzor novog Windows stroja. Otvorite datoteku windows.cfg za uređivanje pomoću uređivača Vi.

[root@tecmint]# vi /usr/local/nagios/etc/objects/windows.cfg

Uzorak Windows definicije glavnog računala već je definiran za Windows stroj, možete jednostavno promijeniti definiciju glavnog računala kao što su polja host_name, alias i address u odgovarajuća vrijednosti vašeg Windows stroja.

Define a host for the Windows machine we'll be monitoring
Change the host_name, alias, and address to fit your situation

define host{
        use             windows-server  ; Inherit default values from a template
        host_name       winserver       ; The name we're giving to this host
        alias           My Windows Server       ; A longer name associated with the host
        address         172.31.41.53    ; IP address of the host
        }

Sljedeće usluge već su dodane i omogućene u datoteci windows.cfg. Ako želite dodati neke druge definicije usluga koje je potrebno nadzirati, možete jednostavno dodati te definicije u istu konfiguracijsku datoteku. Provjerite jeste li promijenili host_name za sve ove usluge s host_name definiranim u gornjem koraku.

define service{
	use			generic-service
	host_name		winserver
	service_description	NSClient++ Version
	check_command		check_nt!CLIENTVERSION
	}

Add the following service definition to monitor the uptime of the Windows server.

define service{
	use			generic-service
	host_name		winserver
	service_description	Uptime
	check_command		check_nt!UPTIME
	}

Add the following service definition to monitor the CPU utilization on the Windows server and generate a CRITICAL alert if the 5-minute CPU load is 90% or more or a WARNING alert if the 5-minute load is 80% or greater.

define service{
	use			generic-service
	host_name		winserver
	service_description	CPU Load
	check_command		check_nt!CPULOAD!-l 5,80,90
	}

Add the following service definition to monitor memory usage on the Windows server and generate a CRITICAL alert if memory usage is 90% or more or a WARNING alert if memory usage is 80% or greater.

define service{
	use			generic-service
	host_name		winserver
	service_description	Memory Usage
	check_command		check_nt!MEMUSE!-w 80 -c 90
	}

Add the following service definition to monitor usage of the C:\ drive on the Windows server and generate a CRITICAL alert if disk usage is 90% or more or a WARNING alert if disk usage is 80% or greater.

define service{
	use			generic-service
	host_name		winserver
	service_description	C:\ Drive Space
	check_command		check_nt!USEDDISKSPACE!-l c -w 80 -c 90
	}

Add the following service definition to monitor the W3SVC service state on the Windows machine and generate a CRITICAL alert if the service is stopped.

define service{
	use			generic-service
	host_name		winserver
	service_description	W3SVC
	check_command		check_nt!SERVICESTATE!-d SHOWALL -l W3SVC
	}

Add the following service definition to monitor the Explorer.exe process on the Windows machine and generate a CRITICAL alert if the process is not running.

define service{
	use			generic-service
	host_name		winserver
	service_description	Explorer
	check_command		check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe
	}

Na kraju uklonite komentar s datoteke windows.cfg u /usr/local/nagios/etc/nagios.cfg.

[root@tecmint]# vi /usr/local/nagios/etc/nagios.cfg

Definitions for monitoring a Windows machine
cfg_file=/usr/local/nagios/etc/objects/windows.cfg

Na kraju provjerite ima li u konfiguracijskim datotekama Nagios grešaka.

[root@tecmint]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Total Warnings: 0
Total Errors:   0

Things look okay - No serious problems were detected during the pre-flight check

Ako postupak provjere izbaci bilo kakvu poruku o pogrešci, popravite te pogreške dok se postupak provjere ne završi bez poruka o pogrešci. Nakon što ispravite te pogreške, ponovno pokrenite uslugu Nagios.

[root@tecmint]# service nagios restart

Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.

To je to. Sada idite na web sučelje Nagios Monitoring na “http://IP-adresa-poslužitelja/nagios” ili “http://FQDN/nagios” i unesite korisničko ime “nagiosadmin ” i lozinka. Provjerite je li Udaljeni Windows host dodan i nadzire li se.

To je to! za sada ću vam u svom nadolazećem članku pokazati kako dodati Pisač i Prekidače na Nagios poslužitelj za nadgledanje. Ako imate bilo kakvih poteškoća prilikom dodavanja hosta Windows u Nagios. Komentirajte svoje upite putem odjeljka za komentare, a do tada pratite linux-console.net za još ovakvih vrijednih članaka.
