Probleme mit MRTG

Benny² · Dec 26, 2011

Hallo,

in diesem Tutorial habe ich einfahc mal bei mir auf den Server gezogen und etwas bearbeitet. Nun sieht meine Config so aus:

# Created by
# /usr/bin/cfgmaker public@localhost

### Global Config Options

# for UNIX
# WorkDir: /home/http/mrtg

# for Debian
WorkDir: /var/www/virtual/eplay-tv.de/status/htdocs

# or for NT
# WorkDir: c:\mrtgdata

### Global Defaults

# to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

EnableIPv6: no

PS:
Nutze Debian 6
So sieht es aktuell aus http://status.eplay-tv.de/

Die gezeichneten Graphen haben alle eins gemeinsam:
Sie beziehen die Daten aus Scripten.
Bei den nicht gezeichneten Graphen ist es genau das Gegenteil: Es sind SNMP-Daten.
Ergo liegt der Fehler im SNMP.

Nun lässt "error status: noSuchName" den Schluss zu, dass hier irgendwas unbekannt ist.
Ich tippe darauf dass Deine "LoadMIBs" falsch sind. Check das mal, denn bei Debian 6 werden die glaub ich ohne .txt geschrieben.

Benny² · Dec 28, 2011

Ja stimmt, hab jetzt auch gerade geschaut in dem Ordner wohin er gehen will, aber den Ordner gibt es nicht und in dem Ordner wo ich es vielleicht vermute finde ich nicht das was es sein könnte.

Weißt du vielleicht, welche Dateien das sein könnten?

Huschi · Dec 28, 2011

Ein "locate UCD-SNMP-MIB" sollte helfen.
Bei mir liegen sie unter /usr/share/mibs/netsnmp. Aber ohne .txt am Ende wie noch in Debian 5.

Jo, super da hab ich die Dateien gefunden - Nur leider hat sich bislang nicht viel verändert, außer das der Log jetzt eine andere Fehlermeldung ausspuckt

Das Problem mit mrtg-sensors kannst Du auf der Console prüfen.
Die anderen per snmpwalk:

Code:

snmpwalk -c public localhost

Evtl. ist "public" nicht in der richtige snmp-Community-Name?

huschi.

also wenn ich dein code eingebe, bekomme ich das aus der Konsole:

/etc/snmp/snmp.conf: line 9: Warning: Unknown token: com2sec.
snmpwalk: No securityName specified

So sieht die Config aus:

#
# As the snmp packages come without MIB files due to license reasons, loading
# of MIBs is disabled by default. If you added the MIBs you can reenable
# loaging them by commenting out the following line.
mibs :

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

Was ist daran falsch?

Huschi · Dec 28, 2011

"com2sec" gehört eigentlich in die snmpd.conf.
Aber selbst dort hab ich es draußen und statt dessen:

Code:

rocommunity public localhost

Die snmp.conf hingegen ist vollständig leer (nur Kommentare).

huschi.

Benny² · Dec 30, 2011

also ich hab die snmp.conf mal auskommentiert und in der snmpd.conf finde ich auch den code, bloß mit -V systemonly dahinter.

Bloß, wenn das jetzt läuft, snmp ist auch restartet, läuft es nicht und wenn ich dein code oben ausführe, bekomm ich die Meldung snmpwalk: No securityName specified

Hier mal den komplette Conf von der snmpd-Datei

Und statt localhost steht da default. Was verlierst Du wenn Du meinen Vorschlag einfach übernehmen würdest zum Testen?

Das Problem mit mrtg-sensors hatte ich oben schon angegangen. Du anscheinend noch nicht.

SNMPGET Problem for ifInOctets.0 ifOutOctets.0 sysUptime sysName on
public@localhost::::::v4only

Woher das kommt, kann ich Dir nicht sagen. Denn diese Einstellung steht oben in Deiner Config nicht.
Aber wahrscheinlich fehlt die Verknüpfung mit der IF-MIB-Datei.

huschi.

Benny² · Dec 30, 2011

also wenn ich in der console sensors eingebe, bekomme ich solch eine liste, aber in der config habe ich coretemp... auch eingetragen, es bringt aber nichts.
und von fan-sensoren habe ich das auch noch nichts entdeckt.

Code:

# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +38.0°C  (high = +80.0°C, crit = +99.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +38.0°C  (high = +80.0°C, crit = +99.0°C)

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +38.0°C  (high = +80.0°C, crit = +99.0°C)

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +39.0°C  (high = +80.0°C, crit = +99.0°C)

Was soll denn die IF-MIB-Datei auslesen?
Denn bis jetzt fehlt nur noch der Traffic und die SWAP-Grafik
(außer natürlich die Temperatur und der Fan)

Huschi · Jan 2, 2012

Wer lesen kann ist klar im Vorteil:
Es geht um den Befehl "mrtg-sensors".

Das "IF" steht für "Interface" womit Deine Netzwerkkarte gemeint ist. (=> Traffic)
Aber hier musst Du selber erstmal die passende MRTG-Config suchen. Das kann man Dir auf die Entfernung nicht abnehmen.

Nicht bei allen OVH Servern kannst du einen Lüfter auslesen. OVH setzt ja auf Wasserkühlung.
