[DEBIAN] MRTG

[Verwijderd]

Mensen Ik draai nu al een hele tijd met tevreden heid debian maar ik kom er niet uit hoe ik MRTG moet instellen dat die mijn trafic van eth0 bij houd hij installeert goed maar daarna gaat het fout. Ik zal er voor de zeker heid een stukje kopieren uit mijn log files en mijn mrtg.conf er bij zetten.

heb je wel snmp geinstaleerd?

Wat doet dat pakketje precies ?

dat zorgt ervoor dat er informatie over eth0 wordt verzameld, en van die deamon maakt mrtg weer gebruik.

Nu krijg ik de volgende fout in mijn logfiles hoe los ik dit op?

snmpd.conf:
###############################################################################
#
# EXAMPLE.conf:
# An example configuration file for configuring the ucd-snmp snmpd agent.
#
###############################################################################
#
# This file is intended to only be an example. If, however, you want
# to use it, it should be placed in /etc/snmp/snmpd.conf.
# When the snmpd agent starts up, this is where it will look for it.
#
# All lines beginning with a '#' are comments and are intended for you
# to read. All other lines are configuration commands for the agent.

#
# PLEASE: read the snmpd.conf(5) manual page as well!
#


###############################################################################
# Access Control
###############################################################################

# By far, the most common question I get about the agent is "why won't
# it work?", when really it should be "how do I configure the agent to
# allow me to access it?"
#
# By default, the agent responds to the "public" community for read
# only access, if run out of the box without any configuration file in
# place. The following examples show you other ways of configuring
# the agent so that you can change the community names, and give
# yourself write access as well.

# The following lines change the access permissions of the agent so
# that the COMMUNITY string provides read-only access to your entire
# NETWORK (EG: 10.10.10.0/24), and read/write access to only the
# localhost (127.0.0.1, not its real ipaddress).

# For more information, read the FAQ as well as the snmpd.conf(5)
# manual page.

####
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

# sec.name source community
com2sec paranoid default public
#com2sec readonly default public
#com2sec readwrite default private

####
# Second, map the security names into group names:

# sec.model sec.name
group MyROSystem v1 paranoid
group MyROSystem v2c paranoid
group MyROSystem usm paranoid
group MyROGroup v1 readonly
group MyROGroup v2c readonly
group MyROGroup usm readonly
group MyRWGroup v1 readwrite
group MyRWGroup v2c readwrite
group MyRWGroup usm readwrite

####
# Third, create a view for us to let the groups have rights to:

# incl/excl subtree mask
view all included .1 80
view system included .iso.org.dod.internet.mgmt.mib-2.system

####
# Finally, grant the 2 groups access to the 1 view with different
# write permissions:

# context sec.model sec.level match read write notif
access MyROSystem "" any noauth exact system none none
access MyROGroup "" any noauth exact all none none
access MyRWGroup "" any noauth exact all all none

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file:

syslocation Unknown (configure /etc/snmp/snmp.local.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

# Example output of snmpwalk:
# % snmpwalk -v 1 localhost public system

# system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4

###############################################################################
# Process checks.
#
# The following are examples of how to use the agent to check for
# processes running on the host. The syntax looks something like:
#
# proc NAME [MAX=0] [MIN=0]
#
# NAME: the name of the process to check for. It must match
# exactly (ie, http will not find httpd processes).
# MAX: the maximum number allowed to be running. Defaults to 0.
# MIN: the minimum number to be running. Defaults to 0.

#
# Examples:
#

# Make sure mountd is running
proc mountd

# Make sure there are no more than 4 ntalkds running, but 0 is ok too.
proc ntalkd 4

# Make sure at least one sendmail, but less than or equal to 10 are running.
proc sendmail 10 1

# A snmpwalk of the process mib tree would look something like this:
#
# % snmpwalk -v 1 localhost public .1.3.6.1.4.1.2021.2
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2

# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
#
# Note that the errorFlag for mountd is set to 1 because one is not
# running (in this case an rpc.mountd is, but thats not good enough),
# and the ErrMessage tells you what's wrong. The configuration
# imposed in the snmpd.conf file is also shown.

Waarschijnlijk draait snmpd nog niet lang genoeg. (alhoewel... ) Je het snmpd wel gestart he (moet bij elke boot trouwens weer - dus stel dat even in als dat nog niet zo is). Probeerde je het gelijk?

Je moet ook even goed kijken of de configuratie van smnpd wel overeenkomt met mrtg (vooral die dingen als 'public' enzo).

[M4RTiN]

nu werkt je snmap wel maar geeft een error terug

hoe stel je je mrtg in? via ip 127.0.0.1? zoniet probeer dat eens

waarschijnlijk moet je snmpd eerst goed configgen

[gekkie]

MRTG hoeft geen gebruik te maken van SNMP als alleen de gegevens van dezelfde machine wilt weergeven.
Het is ook mogelijk de resultaten van bijvoorbeeld perl-scripts weer te geven met MRTG.
Eens zoeken op de homepage van MRTG, daar staan wel links naar pagina's met voorbeeld configuraties en scripts !

[sebas]

je moet ook een keer snmpwalk hebben gedraaid, voor details

code:

user@host:~ > man snmpwalk

... my $.02

Jopie hij draait goed maar nog 2 dingen die niet goed werken. Als het goed is maakt die statstieken van eth0 maar bij de uitlezing van de grafiek komt die niet oven de 3b uit hoe komt dit ? En heb ik mijn snmpd nu veilig ingesteld?
