how to do this graphing in nagios

[h.sabrey]

Hello Gents,

as long as my work with nagios core continues my linux experience is improving "Thanks Nagios", and of course much more requirements pops up.

we have the devices of mikrotik, ubnt, and cisco in the network and of course linux servers for radius and nagios which all needed to be monitored. now, after installing nagios, i want to monitor the network in terms of SNMP parameters graphing it and record this data for 30 days.

SNMP parameters are (PING, Traffic, CPU load, up-time) and the bandwidth of the internet.

how to start and where to begin, if any problems faced, it'll be posted here, to make knowledge available for all.

thanks for the link, but is the only graphing tool for nagios?

[Box293]

There are other tools available, PNP4Nagios is the only one I've played with.

what about MRTG, is it integratable to the Nagios?

[Box293]

It certainly is.

Honestly I use Nagios XI which includes MRTG so I've never had to set it up from scratch, however I'm sure if you follow the documentation you'll get it working.

which documentation, describe the integration between nagios and MRTG

[rkennedy]

I couldn't find much instruction on MRTG / Nagios, but I will direct you to our exchange which has a Graphing addons available.

while the installation the last part about editing the command.cfg and the nagios.cfg

for the nagios.cfg
command to be executed from the website is :-

Code: Select all

Type sed -i 's/^#host_perfdata_file_template=.*/host_perfdata_file_template=DATATYPE::HOSTPERFDATA\\tTIMET::$TIMET$\\tHOSTNAME::$HOSTNAME$\\tHOSTPERFDATA::$HOSTPERFDATA$\\tHOSTCHECKCOMMAND::$HOSTCHECKCOMMAND$\\tHOSTSTATE::$HOSTSTATE$\\tHOSTSTATETYPE::$HOSTSTATETYPE$/g' /usr/local/nagios/etc/nagios.cfg and press Enter

Type sed -i 's/^#service_perfdata_file_template=.*/service_perfdata_file_template=DATATYPE::SERVICEPERFDATA\\tTIMET::$TIMET$\\tHOSTNAME::$HOSTNAME$\\tSERVICEDESC::$SERVICEDESC$\\tSERVICEPERFDATA::$SERVICEPERFDATA$\\tSERVICECHECKCOMMAND::$SERVICECHECKCOMMAND$\\tHOSTSTATE::$HOSTSTATE$\\tHOSTSTATETYPE::$HOSTSTATETYPE$\\tSERVICESTATE::$SERVICESTATE$\\tSERVICESTATETYPE::$SERVICESTATETYPE$/g' /usr/local/nagios/etc/nagios.cfg and press Enter

command in the original file is

Code: Select all

#host_perfdata_file_template=[HOSTPERFDATA]\t$TIMET$\t$HOSTNAME$\t$HOSTEXECUTIONTIME$\t$HOSTOUTPUT$\t$HOSTPERFDATA$
#service_perfdata_file_template=[SERVICEPERFDATA]\t$TIMET$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$

what i understood that we need to uncomment the lines in the original file while the comment in the website is quite different.

great thanks for BOX293, only something related to configuration

##
we want to monitor and graph the PING, || Port1, Port2, Port3,.... etc || and the most important the bandwidth of Port1 in each device.

the configuration is done according to the 3 file strtgy, i.e. file1= routerhostgroups.cfg, file2= routerservicegroup.cfg, file3= xx_routername.cfg

below is the configuration of :
:::: File1

Code: Select all

define hostgroup{
	hostgroup_name       Local_Routers         ; The name of the hostgroup
#	alias				Local Routers         ; Long name of the group
	}

:::: File2

Code: Select all

# Create a service to PING to router

define service{
	use					generic-service							; Inherit values from a template
	hostgroup_name		Local_Routers							; The name of the hostgroup the service is associated with
	service_description		PING									; The service description
	check_command		check_ping!200.0,20%!600.0,60%			; The command used to monitor the service
	normal_check_interval	5									; Check the service every 5 minutes under normal conditions
	retry_check_interval		1									; Re-check the service every minute until its final/hard state is determined
	}


# Monitor uptime via SNMP

define service{
	use					generic-service							; Inherit values from a template
	hostgroup_name		Local_Routers							; The name of the hostgroup the service is associated with
	service_description		Uptime	
	check_command		check_snmp!-C public -o sysUpTime.0
	}



# Monitor Port 1 status via SNMP

define service{
	use					generic-service							; Inherit values from a template
	hostgroup_name		Local_Routers							; The name of the hostgroup the service is associated with
	service_description		Port 1 Link Status
	check_command		check_snmp!-C public -o ifOperStatus.1 -r 1 -m RFC1213-MIB
	}



# Monitor bandwidth via MRTG logs

define service{
	use					generic-service							; Inherit values from a template
	hostgroup_name		Local_Routers							; The name of the hostgroup the service is associated with
	service_description		Port 1 Bandwidth Usage
	check_command		check_local_mrtgtraf!/var/lib/mrtg/192.168.1.20_1.log!AVG!1000000,1000000!5000000,5000000!10
	}
# 192.168.1.20 is the router Port1 IP

:::: File3

Code: Select all

# 001.MySite1
define host{
	use			generic-router					; Inherit default values from a template
	host_name	001.MySite1					; The name we're giving to this Router
#	alias			001.MySite1					; A longer name associated with the Router
	address		192.168.1.20					; IP address of the Router
	hostgroups	Local_Routers, 03-Al-Mahari		; Host groups this Router is associated with

but...
when getting in the nagiosserver/nagios/pnp/index.php the only graphed is the "001.MySite1" Host & Ping.

want to graph the:-
1- per single host => PING, Port1 status, uptime & Traffic bandwidth for Port1
2. sum of (Traffic bandwidth of port1 of all devices) . this to know the overall traffic consumed
